K D Engineering Document No. Q439-03-028-01 12 August 2011 KDE FORM No. A263a-7/12/99

1.0 SUMMARY Lydian International, LTD. (Lydian) has engaged K D Engineering (KDE), an independent engineering firm located in Tucson, Arizona, to prepare a Preliminary Economic Assessment (PEA) of the Amulsar heap leach facility. The KDE study was prepared to standards pursuant to Canada’s National Instrument 43-101 (NI 43-101) and was based on the following:

▪ KDE site visit conducted in May 2011

▪ Geological review, mineral resource estimates, estimates of potentially mineable mineral (PMM) and mine capital and operating cost estimates completed by CSA Global (UK)

▪ Heap leach facility design and cost estimates by Golder Associates Inc.

(Golder)

▪ Metallurgical testing by SGS Lakefield, SGS Cornwall and Wardell Armstrong International

▪ Environmental and Social Impact Scoping Study February 2011 plus a July

review of the content of this PEA by Wardell Armstrong International 1.1 Geology, Exploration and Resource Estimation The Amulsar Project is covered by two special prospecting licenses (SPL) No 41 and 42, along with a small mining license, No 14/588. The licenses are held by Geoteam CJSC, a 95 percent owned subsidiary of Lydian. Lydian has the option to purchase the remaining 5 percent. The SPL’s were granted in 2009 and are valid for 5 years with the potential to extend the period. The mining license is valid for 25 years.

The Amulsar high sulphidation gold deposit is situated in central Armenia and is hosted in the Upper Eocene to Lower Oligocene calc-alkaline magmatic-arc system that extends north-westward through southern Georgia into Turkey and south-eastwards into the Alborz-Arc of Iran. The volcanic and volcano-sedimentary rocks of this system comprise a mixed marine and terrigenous sequence that is interpreted to have developed as a near-shore continental arc along the southern margin of the Eurasian Plate and at the northern limit of the Neo-Tethyan Ocean. The Neo-Tethyan ocean closed and subduction ceased along this margin in the Early Oligocene when a fragment of continental crust known as the Sakarya continent, collided at the trench axis and accreted with the Eurasian plate.

Geological structures represent a very important control on gold mineralization

throughout the Amulsar deposit. Both NE and NW striking, steeply dipping, structures are the dominant trends at Tigranes and Artavasdes, whilst at Erato the dominant structural trend strikes at approximately 010 degrees and dips steeply to the west. There is no one obvious alteration facies that hosts the gold mineralization at Amulsar,

and this relates in part to the fact that the gold resides in late structures that cut lithologies and units that have been affected by multiple alteration events. Lydian has developed the following sequence of alteration events at Amulsar. Sequence of Alteration Events

▪ The emplacement of a high level intrusive into a volcanic pile resulted in extensive clay alteration, followed closely by silicification of ledges within the core area with surrounding clay alteration remaining.

▪ Silica-alunite alteration with the generation of second phase breccias and the

introduction of sulphide (dominantly pyrite) gold-silver ± copper mineralization.

▪ Later supergene processes caused the oxidation of sulphide material within

silica altered bodies to depths of over 200 m. The alteration observed at Amulsar appears indicative of being in the deeper parts of the high sulphidation epithermal system. Gold mineralisation at Amulsar is a late event in the development of the deposit. Gold occurs within limonitic zones after the oxidation of sulphide material, and three dominant controls on the localisation of gold mineralization have been defined. Sequence of Mineralizing Events

▪ The argillic altered (kaolinised) porphyritic andesite formed an impermeable barrier to mineralising fluids, and caused ‘ponding’ of higher grade mineralization along the contacts

▪ Faults and fractures provided conduits for the introduction of gold mineralising

fluids

▪ Porous and permeable lithological units (hydrothermal breccias, volcaniclastic breccias, and occasional leached/vuggy volcanics) allowed for the lateral migration of mineralising fluids away from structurally controlled conduits

The presence of silver mineralization is not well understood, and does not appear to correlate strongly with gold grades. Silver values average between 2.0 g/t silver and 5 g/t silver, although tenors can reach greater than 100 g/t within narrow intervals. Copper and other base metals are virtually absent from the areas explored to date. Mineral Resource Estimate The May 2011 Mineral Resource estimate has been utilized for this PEA. This was an update of two previous Mineral Resource estimates that were released in March 2010 and March 2009. The April 2011 Mineral Resource estimate was based upon the

results of diamond and RC drilling completed between 2008 and 2010 plus additional grade data from channel sampling undertaken on outcrops at Amulsar. During 2010 Lydian staff undertook a thorough review of the Amulsar geology, including surface mapping, logging of oriented drill core and closer spaced infill drilling which resulted in the generation of a more robust geological model, where lower grade strata-bound mineralization and higher grade structural bound mineralization are defined. Diamond drill recovery during 2010 was good, increasing from 93 percent in 2009 to 96 percent in 2010. Reverse circulation (RC) recovery increased from 72 percent in 2009 to 89 percent in 2010. Overall there does not appear to be a strong trend of greater than 0.2 ppm gold value samples (resource grade) that exhibit poor recovery. Bulk density has been determined by paraffin wax sealed method, and for the current mineral resource estimate the following bulk densities were assigned to the dominant lithologies.

▪ Breccias = 2.33 g/cm3 ▪ Volcanic = 2.41 g/cm3 ▪ Porphyritic Andesite = 2.24 g/cm3

CSA Global (UK) (CSA) conducted a thorough review of the assay results

collected from RC drilling and diamond drilling and believe these to be reliable for the purposes of resource estimation. RC and diamond assay datasets exhibit similar population distributions and are considered compatible for use in resource estimation. Assays on blank material inserted by Lydian demonstrate minimal contamination whilst duplicate samples show acceptable levels of accuracy and precision. CRM charts show acceptable levels of accuracy and precision, however there are a number of outliers which appear to be a result of incorrect labelling of CRM’s.

The mineral resource estimate comprised two sets of domain wireframes, the first based on 0.2 g/t gold to 0.3 g/t gold sub-horizontal strata-bound material and the second based on 0.3 g/t greater gold focused on mineralization that is structurally controlled. Domain wireframes were created by Lydian with input from CSA. The structural domains were then grouped according to their dominant strike orientation. A total of 12 domains were identified and used during mineral resource estimation. For the mineral resource estimation procedure, sample data was composited to one meter intervals prior to top cut analysis. Variography was performed on the larger domains, with these models being applied to the smaller domains where cross validation showed a positive correlation between the two populations. As a result of the geostatistical assessment Ordinary Kriging (OK) was used for the estimation of gold grade in all domains. Gold grade was estimated into a block model with cells 20 m x 20 m x 5 m (X x Y x Z), sub celled down to 2 m x 2 m x 0.5 m (X x Y x Z). Bulk density was assigned according to dominant rock type.

The May 2011 Amulsar Mineral Resource estimate has been classified in accordance with CIM guidelines A CIM compliant Indicated and Inferred Mineral Resource, reported at a 0.4 g/t gold cut-off totals 80.7 million tonnes at 0.97 g/t gold for 2.52 million contained ounces of which 32.4 million tonnes at 1.1 g/t gold for 1.1 million

ounces are contained within the Indicated resource and 48.3 million tonnes at 0.9 g/t gold for 1.4 million ounces contained within the Inferred resource (Ref CSA NI 43-101 May 2011, quoted here to one decimal place).

1.2 Mining

The selected Amulsar Whittle optimisation shell for the Indicated resource option contains 31.0 million tonnes of Potentially Mineable Mineralisation (PMM), allowing for 5 percent PMM loss and 5 percent waste dilution, at an average head grade of 0.98 g/t and 75.9 million tonnes of waste, resulting in an overall strip ratio of 2.45:1. The selected pit shell provides a “specified discounted cash flow” of US$ 263.75 million with two push backs. These figures exclude capital expenditure.

The selected Amulsar Whittle optimisation shell for the Indicated and Inferred resource option contains 53.6 million tonnes of PMM, allowing for 5 percent PMM loss and 5 percent waste dilution, at an average head grade of 0.94 g/t and 138.0 million tonnes of waste resulting in an overall strip ratio of 2.57:1. The selected optimum pit shell provides a “specified discounted cash flow” of US$ 367.08 million with two push backs. These figures exclude capital expenditure.

The optimisation work that has been completed, based on the input parameters provided by Lydian, demonstrates that the Amulsar gold deposit has the potential to be a financially viable operation.

The conversion factors from resources to PMM are favourable for both the

Indicated resources option and the combined Indicated and Inferred resources option.

The limits of the Whittle pit shell generated using the current mineral resource model, demonstrates that exploration should be extended both laterally and at depth.

This initial optimisation work demonstrates that a portion of the resources which are currently in the Inferred Category have the potential to be economically mineable. Further drilling should therefore be carried out within this portion of the Inferred resources to bring them to the Indicated Category.

The aforementioned scoping study is based on parameters determined at a

conceptual stage. Additional work and detail is required to:

▪ Convert Inferred resources at Tigranes and Artavasdes to Indicated resources to enable potential conversion to Probable Reserves. This will require additional drilling and geological investigation.

▪ Convert at least the first 3 years of potentially mineable mineralization to

measured resources allowing conversion to Proven Reserves. This will need additional drilling and detailed geological analysis.

▪ Carry out adequate hydrological test work to quantify if there are risks associated with water inflow into the pit including groundwater, snow and rainfall in order to achieve the required level of confidence for pit slope designs and life-of-mine planning.

▪ Carry out adequate geotechnical test work to enable accurate design of pit

slope angles based on both wet and dry pit walls. 1.3 Metallurgy To date scoping level testwork has been completed by SGS Lakefield/SGS Cornwall (SGS) and Wardell Armstrong International (WAI) on samples from the Amulsar project. Initial exploratory testwork carried out by SGS investigated the following process routes:

▪ Gravity ▪ Whole ore cyanidation leach (Carbon in Leach) ▪ Coarse ore cyanidation leach (Heap Leach)

Gravity tests showed that the Gravity Recoverable Gold (GRG) component at Amulsar is very low with 8.5 percent GRG recovered to a low grade sulphide concentrate. Whole ore cyanidation leach tests conducted at various grind sizes ranging from 75 to 150 µm resulted in gold leach recoveries of circa 97 percent, after 48 hours of leaching.

Coarse ore bottle roll leach tests conducted at various crush sizes ranging from 1/2 to 1/4 inch resulted in a gold leach recovery of 96 percent at the finest crush size, after 15 days of leaching. Based on the preliminary characterization testwork it was concluded that the Amulsar ore would be amenable to processing by heap leach technology.

Further testwork was carried out on composites generated by combining core

samples from the Tigranes and Artavasdes deposits and considered by Lydian geologists to be representative. Again, testwork explored conventional CIL versus heap leach technology. A summary of the testwork results is shown in Table 1.1 below.

Table 1.1 shows that there is a direct correlation between sample crush/grind

size and gold leach recovery, i.e. the finer the size of the sample the higher the gold

leach recovery as a result of better gold liberation. These initial scoping testwork results indicated good recoveries and potentially attractive processing economics of the Amulsar project if the bulk mined low-grade ore is prepared using a 3-stage crushing facility and heap leached.

Lydian commissioned WAI to undertake an additional program of laboratory

testwork on samples from the Amulsar deposit. WAI conducted further bottle roll and column tests on the two composite samples originally tested by SGS. The testwork generally focused on leaching at finer crush sizes (-38mm, -19mm and -12mm) and using higher cyanide concentrations (0.025 to 0.075 percent NaCN) than were used in the SGS testwork.

It is concluded that, from the column test results, the optimum crush size for both

samples is probably 19 millimeter and the optimum cyanide concentration is 0.05 percent, although further work to determine the impact of cyanide concentration upon silver extraction will be required.

In late 2010, Lydian shipped whole core from three diamond drill holes representing each of the deposits; Tigranes, Artavasdes and Erato. Composite samples were also prepared representing each of the main four metallurgical rock types including: pervasive iron oxide, gossan, fault gouge and siliceous breccia.

The objectives of the testwork program were to determine variability of gold leach recovery arising from rock type, and crush size. WAI were commissioned to conduct both coarse bottle roll leach tests and column leach tests. Tests were conducted on individual drill hole intervals, at crush sizes of -19 mm and -12 mm.

Results of the coarse bottle roll cyanidation leach tests conducted for 14 days are

summarized in Table 1.2.

Table 1.2 Coarse Bottle Roll Cyanidation Leach Test Summary

Drill Hole Deposit Leach Recovery, %

Gold Silver -12 mm -19 mm -12 mm -19 mm

DDAM68 Erato 97.0 96.5 42.7 45.9 DDAM70 Artavasdes 86.5 82.8 44.0 36.3 DDAM71 Tigranes 90.7 89.2 42.8 48.7

The coarse bottle roll leach tests again showed that a higher gold leach recovery

was achieved with the finer crush size. Gold leach recovery at -12mm was 2 percent higher on average, compared to those achieved at a crush size of -19mm.

The coarse bottle roll leach tests also showed that there was no leach variability

arising from the different rock types represented at the Tigranes, Artavasdes and Erato deposits. The outcome of the coarse bottle roll leach tests was to prepare composite samples for column leach tests. Composite samples representing the four major rock types and each of the deposits were prepared and are currently being leached.

Particle size determinations conducted on each of the composite samples

prepared for the column leach tests indicated that the percentage of -38 µm was on average 5 percent by weight for all column samples. Hence it was decided not to conduct any percolation/agglomeration tests ahead of the column leach tests. Percolation tests will be conducted once the column has been terminated.

The test results confirmed that the Amulsar gold mineralization is amenable to

recovery using heap leach technology. Conventional three-stage crushing, followed by stacking, leaching and carbon-in-column (CIC) gold recovery is suggested.

Initial column leaching was exceptionally rapid for both samples with up to 80

percent gold recovery being recovered after seven days of leaching at a crush size minus 12 mm. Initial column leach testing indicate that greater than 85 percent gold leach extraction is attainable after 70 days of leaching.

Column leach tests also indicate that cyanide and lime consumption rates are

low at 0.4 kg/t and 1.0 kg/t respectively. 1.4 Recovery Methods

Run-of-mine ore will be hauled from the pit to the three stage crushing plant located in proximity to the mine. Haulage from pit to crushing is 1 kilometer or less. The crushing plant consists of primary crushing through a jaw crusher, secondary crushing through a cone crusher, and tertiary crushing through a pair of cone crushers. The circuit will reduce ROM ore from minus 700 millimeter top size to a product of 80 percent passing 12 millimeters and is designed to process ore at a rate of 5 Mtpa. In the first year of operation 3.75 Mtpa will be processed and 5 Mtpa in year two. Installation of a duplicate circuit ramps up production to 7.5 Mtpa in year 3 and to 10 Mtpa for Year 4 and through the life of the project.

Crushed ore will be transported approximately 3.5 kilometers on an overland

conveyor to be distributed along the north side of the leach pad. Pebble lime will be added to the ore while on the overland conveyor. A tripper conveyor will deliver the ore from the overland conveyor to a series of initially eight, ultimately twenty four, portable conveyors. A stacking conveyor will place the ore on the leach pad in lifts of a nominal thickness of 8 meters.

The heap leach pad will be constructed in three phases. The first phase, suitable

for the first three years of operation, will have an area of 347,430 m2 and will accommodate 13.4 Mt of ore in six 8-m lifts. The second phase will add 431,100 m2 of pad area and accommodate 28.9 Mt of ore in four 8-m lifts above the Phase 1 pad heap and the Phase 2 pad. The third phase will add 265,630 m2 of pad area and accommodate 32.7 Mt of ore in six additional lifts, for an ultimate ore heap amount of 75 Mt.

Pregnant leach solution, intermediate leach solution and storm ponds will be located east of the leach pad, and a barren leach solution tank will be located inside the Adsorption-Desorption-Regeneration (ADR) plant near the ponds. Barren and intermediate leach solutions dosed to contain 0.5 gpl sodium cyanide will be applied by drip emitters to the top of the ore heap at irrigation rates of 10 l/h/m2 and will operate to reduce evaporation in summer and allow leaching to continue in winter to maximize PLS gold concentration. These solutions will be stacked such that the barren solution will be used to irrigate the ore in a secondary leach cycle and the intermediate solution will be used to irrigate fresh ore in a primary leach cycle. The primary leach cycle will be 30 days and the secondary 80 days. Leaching of precious metal from the ore will continue as the leached ore is buried by consecutive lifts. After 30 days of buried lift leaching, 140 total leach days, the predicted overall recoveries of 85 and 40 percent for gold and silver respectively, will be attained with an overall leach solution to ore ratio of 3 m3/t.

The barren and intermediate leach solutions will percolate through the ore and be

collected in a network of perforated drain pipes installed within a granular layer above the pad liner. The solution will gravity flow from the drain pipes via transfer pipes exiting the pad and draining into the process ponds. The transfer pipes will direct the solution to either the pregnant or intermediate ponds by valve control.

The pregnant leach solution will be pumped from the pregnant pond into the ADR

plant. Precious metal will be adsorbed from solution onto activated carbon counter-currently in five adsorption columns of 4-t carbon capacity each. Five additional carbon columns will be installed for the Phase II expansion. Carbonate scale will be removed from four-tonne batches of loaded carbon in an acid wash vessel using dilute hydrochloric acid. Precious metal will be desorbed from the acid washed carbon in a strip vessel operating under elevated temperature and pressure. After the carbon is used it will be regenerated in a kiln. The strip solution will report to an electrowinning solution where precious metal will be deposited onto steel mesh cathodes. Weekly, the deposited metal will be washed from the cathodes, dried in a retort to volatilize and collect elemental mercury, and smelted in an induction furnace.

The doré, containing roughly equal proportions of gold and silver, will be shipped

off-site for sale and refining.

1.5 Infrastructure

The Amulsar Gold Project covers an area of 130 km2, located in south central Armenia. Currently paved roads are available to the town of Jermuk and a 15 km dirt road is available from Jermuk to the mine site. Since the proposed mine site is near Jermuk there is no need for a construction camp for this construction effort. Currently an exploration camp is available at site which utilizes a portable generator. There is good infrastructure surrounding the Amulsar project. This includes the main sealed highway between Yerevan and Iran, high tension power lines and substations, a gas pipeline from Iran, year round water from the Vorotan River and a fibre optic internet cable. As a consequence of the project location on the top of a

mountain ridge, a reasonable amount of infrastructure will need to be constructed during project development. Mobile phones work on most parts of the project area. For supplies, material and equipment can be shipped to the ports of Poti or Batumi, Georgia, then trucked through Georgia and Armenia to the Amulsar project site. Community relation issues are currently handled by HSEC manager and a community liaison officer and a good understanding of local issues and sensitivities has been established. The strategy for accommodating all construction personnel, employees and security personnel during the construction period will be detailed as part of the Bankable Feasibility Study (BFS). 1.6 Environmental and Social Impact

Wardell Armstrong International Limited (WAI) was instructed by Lydian

International Limited (Lydian) to undertake an Environmental and Social Impact Assessment (ESIA) for the Amulsar open pit gold project in southern Armenia. The internationally compliant ESIA will be undertaken in parallel with the BFS in order that each process can inform the other and to ensure that environmental and social issues are considered throughout the mine design, construction, operation and closure stages.

The scoping phase of the ESIA has been completed. The purpose of the ESIA Scoping Study is to set out the main project parameters and identify any potential environmental and social impacts. It also sets out the national and international legislative framework and assesses the project status against international standards. Actions required have been identified in detail in a separate Gap Analysis. The main findings of these reports are summarised here, however, for completeness this report should be read in conjunction with the full versions of the Scoping Study and Gap Analysis. The Scoping Study identified no prohibitive social and environmental issues for the project. A number of environmental and social considerations were ascertained through this exercise and associated public consultation events. These issues will form a focal point for further baseline studies in order to better characterise them and provide information on how they might be mitigated. Risks will also be directly addressed via assessments, consultation and the preparation and implementation of relevant management plans. The issues identified, together with the steps required to further quantify and/or mitigate them, include:

▪ Groundwater and surface water hydrology, quality and sustainability - further hydro-geological study, modelling and geochemical assessment via the installation of monitoring wells needs to be undertaken. Site-wide water balance calculations need to be determined and the sustainability of sourcing examined and managed;

K D Engineering Document No. Q439-03-028-01 12 August 2011 KDE FORM No. A263a-7/12/99

▪ Visual impact – The visual impact of the project needs to be assessed from Jermuk, the public highway and village communities, with the results included in public consultations;

▪ Traffic - quantification of mining traffic and a traffic impact assessment is

required;

▪ Land disturbance and take - a land use survey, biodiversity assessment and archaeological study are required to inform an impact assessment and determine any compensation required for grazing lands and any required mitigation or management;

▪ Biodiversity - field surveys need to be undertaken on areas of potential

major disturbance. An ethnobotanical study is also required. The results will inform an overall impact assessment;

▪ Dust - dust dispersion modelling and impact assessment on flora and fauna

used by communities needs to be undertaken;

▪ Noise - Noise impact modelling, incorporating the operating specifics of mine fleet and machinery needs to be undertaken to inform the noise impact assessment on the nearest sensitive receptors;

▪ Cyanide and hazardous materials - As the project will use cyanide in its

heap leach process, the usage, transport, handling and disposal of cyanide will need to be managed via formal plans and procedures in accordance with international best practice, particularly the International Cyanide Management Code (ICMC);

▪ Waste rock - acid- and leachate-generating potential of waste rock types is

being assessed via a program of geochemical testwork. Environmental protection measures and/or management techniques will be incorporated in dump design, if needed;

▪ Local labour - expectations require careful management in an area of high

unemployment and a skills audit to assess future potential employment opportunities should be undertaken;

▪ Social Baseline - supplemental demographic surveys and a health baseline

assessment (to include seasonal visitors) need to be undertaken;

▪ Local Industry - further appraisal of the main (agricultural and manufacturing) sectors is required, including individual contributions to domestic income. An assessment of potential diversification and increase in access to markets with advent of mining is considered beneficial;

K D Engineering Document No. Q439-03-028-01 12 August 2011 KDE FORM No. A263a-7/12/99

▪ Public disclosure and consultation - to be undertaken in line with international best practice, at all stages of the ESIA and mine development processes (to include Jermuk) to manage expectations, allay concerns, establish NGO partnerships, inform community development and spending and influence mine design;

▪ Closure - considerations need to be addressed from conceptual stage via the

preparation and continual update of a Mine Closure and Rehabilitation Plan (MCRP) (to include heap leach rehabilitation).

The findings of the Scoping Study and the terms of reference for continuing work

were presented, in May 2011, to the neighbouring communities. Key issues and observations were noted and are accommodated in the steps listed above. Details of the minutes from these consultation events can be made available on request. Further ESIA public consultation will be held in late 2011 and will include an indication of proposed mine design.

Since the issue of the Scoping Study, Lydian has commissioned several discrete studies in response to the above and has pledged support and resources to the actions identified. Issues, “red flags” were identified that requires detailed studying. A work plan covering all of the red flag items identified above has been developed between Geoteam and WAI and work is progressing against each of these topics. WAI will monitor and review the process of environmental and social baseline data collection by Geoteam, and general progression of the ESIA works, and provide continuing technical support, as required, to ensure that both national and international requirements are met. The baseline programme is continuing and the next ESIA deliverable will be a baseline progress report in third quarter 2011.

1.7 Capital Cost Capital costs for the project were estimated by CSA Global (UK) for mining, KDE for the processing plant and Golder for the leach pad and ponds. The capital expenditures for the Amulsar Project will occur in two phases; years 1 to 3 is Phase I and years 4 through the remaining years is Phase II. The initial and sustaining capital costs for the base case owner operator and contract mining cases are summarized in Table 1.3.

▪ Additional drilling to enhance classification and extension of mineral resources.

▪ Owner operated mining versus contract mining. ▪ Leasing vs. Direct Capital Purchase of Owner Fleet. ▪ In pit waste dumping. ▪ In pit crushing-conveying versus remotely located crushing plant. ▪ Single primary gyratory crusher versus two parallel primary jaw crushers. ▪ Metallurgical optimization on representative sample to fix design criteria and

costs to BFS standards and to enhance silver recovery. ▪ International ESIA compliance work. ▪ Plans for Project operating and project execution. ▪ Risk and Reward assessments.

1.10 Conclusions and Recommendations

This engineering study qualifies as a PEA level document according to Canadian National Instrument 43-101. The economic models utilized in this report indicated a range of before tax rate of return from 39.5 to 46.0 percent at an assumed gold price of US$ 1,200 per ounce. If the gold price used in the economic evaluation, which excludes inferred resources, is increased to current levels (US$ 1,500 per ounce in July 2011), then the before tax rate of return ranges from 54.7 to 61.8 percent.

The studies to date have not indicated any major difficulties or costs in

establishing the necessary infrastructure facilities to support the operation. Several opportunities were proposed by the client and their consultants to further reduce the overall capital or operating costs including the following:

▪ Project development of a phased approach to the construction effort.

▪ Additional drilling and metallurgical testing to define the Amulsar deposit.

▪ Further develop the trade off studies including contract vs. owner operated

mining and a crusher equipment layout and location optimization.

Based on the optimization work that has been completed, using the input parameters provided by Lydian, the Amulsar gold deposit has the potential to be a financially viable operation and it is recommended that this be advanced to a BFS.

4.0 PROPERTY DESCRIPTION AND LOCATION

The following property description and location is a summary taken from the 19 May 2011 NI 43-101 report mentioned in the Introduction of this report and from Lydian documentation.

4.1 Summary The Amulsar Gold Project covers an area of 130 km2, located in south central Armenia (Figure 4.1). The project area is covered by two Special Prospecting Licenses (SPL). The Saravan license (No 42) and the Gorayk license (No 41). A small Mining License (No 14/588) has also been granted, which covers the Amulsar area. The current SPL’s were granted in August 2007, following the conversion of the original Amulsar license (No 193) to a mining license. Five years is allowed for exploration, with two extensions of two years allowed, before a mining license application must be submitted. A 17 km2 extension to the Saravan license was awarded in May 2011. The Armenian Ministry of Energy and Natural Resources approved an initial C1+C2 reserve of 16.38 t of gold metal in balance and 3.6 t of gold off-balance for the Tigranes site at Amulsar on February 23, 2009. These soviet-style reserves are not CIM compliant. Subsequently an application was submitted for a Mining License which was granted on 4th April 2009. Mining License No 14/588 is valid for 25 years, although under the approved work programme the resource would be exploited in 14.4 years. Lydian has submitted an application to the Armenian Ministry of Energy and Natural Resources, in July 2011, to update the approved resources and to cover both the Tigranes and Artavasdes areas. Following approval of the updated resources Lydian intends to apply for a revised Mining License covering the enlarged resource area. The licenses are held 100 percent by Geoteam CJSC (‘Geoteam’), an Armenian registered closed joint stock company. Geoteam is owned 95 percent by Lydian Resources Armenia (a wholly owned subsidiary of Lydian International Ltd.). Lydian entered into a put and call arrangement under which the terms for the acquisition of the remaining 5 percent have been agreed (Lydian press release dated 10-12-2010).

Armenia’s mining law came into force in April of 2003 and was subsequently amended in December of that year. This law was significantly modified in January 2007 when the National Assembly classified all metallic minerals as strategic and introduced an auction or tender process for all Prospecting and Mining Licenses. There is also a 5-year assurance on foreign investments wherein the investor can choose for that period to operate under the previous or current legislation. The Gorayk and Saravan Special Prospecting licenses (No’s 41 and 42) were awarded to Lydian at auction and were granted under the 2007 mining law. The World Bank is advising the Armenian Government on revisions to the existing mining laws, including royalties, and a revised mining code is expected to be finalized by the end of 2011.

4.2 Armenian Minerals Legislation

A Prospecting License is an exclusive license granted for a term of three years without extension. It is activated by execution of a Concession Contract which regulates the licensee’s activities under the law. If exploration results prove positive, and if there is an indication of economically significant resources, a Prospecting License must be converted within its term to a Special Prospecting License or to a Mining License. A Special Prospecting License is current for a period of between three and five years, but with up to two extensions possible for periods of two years each. On application for a Special Prospecting License the licensee can conclude a Stabilization Contract which is a written agreement with the Republic of Armenia regulating the licensee’s advanced exploration activities under the law. A Mining License is valid for a period of up to 25 years but the actual term is based on the mining plan submitted as part of the Mining License application and the time required to exploit the resource. In the case of Mining License No 14/588 the resource will be exploited in 14.4 years based on the submitted mining rate of 1.5 Mtpa.

Application for a Special Mining License can be submitted at any time but usually follows granting of a Special Prospecting License. Special Prospecting License holders have the entitlement to convert the license to a Special Mining License upon application. Special Mining Licenses are current for a period from twelve to twenty five years, but can be extended upon application by the licensee. Under the 2007 regulations the Prospecting License stage has been annulled for newly awarded ground and only Special Prospecting Licenses, current over 5-year terms, are granted at auction. The execution of a Concession Contract is still required. Concession Contracts for all three Lydian licenses have been executed. 4.2.1 Royalties Armenian Mining royalty tax comprises two components, a Natural Reserves Depletion Fee and Royalty. These are calculated as follows:

▪ Natural Reserves Depletion Fee This is payable on quarterly basis before the 1st day of the second month of the following quarter. The Natural Reserves Depletion Fee is calculated on 1.5 percent of the quantity of the officially approved precious metal reserves depleted during the quarter, using metal prices announced by the Armenian government (based on international market prices).

▪ Royalty Royalties are payable if profitability of a mining license holder exceeds 25 percent. The calculation of the royalty and payment is done on a quarterly basis. Profitability is calculated by the following formula (R-C)/R, where; R - is revenue from mined reserves sold

C - is operational expenses for the same period For each 0.8 percent increase exceeding 25 percent profitability, the payable royalty is 0.1 percent of the revenue amount. Operational expenses are all expenses related to production with the exception of:

▪ Capital expenses ▪ Amortization and depreciation calculated for tangible and non-tangible assets ▪ Financing cost including interests for loans.

The royalties are payable before 30th of the month following the reportable period. 4.2.2 Armenia - Newmont Joint Venture Agreement

In April 2010 Lydian terminated its 50:50 Joint Venture with Newmont and acquired full ownership of the Amulsar project via its 95 percent owned Armenian subsidiary, Geoteam C.J.S.C. Under the agreement Lydian purchased Newmont’s interests in the Joint Venture for a total consideration of US$ 15 million in pre-production payments, additional post production payments and the issuance of 3 million ordinary shares in Lydian on signing the agreement. The preproduction payment is paid in three US$ 5 million tranches. The first tranche was paid on signing the agreement in April 2010, the second tranche is due at the end of 2011 and the final tranche is to be paid either at the end of 2012 or 90 days after completion of a BFS and all permissions to move into production are in place, whichever occurs earliest. Regarding the post production payment, Lydian can elect from three options - to pay Newmont a single payment of US$ 15.6 million on production, to pay an on-going 3 percent NSR, or make 20 quarterly payments of US$ 1 million each. 4.2.3 Environmental Liabilities and Permits There are no special environmental restrictions or known past liabilities in respect to the Amulsar area. Lydian is required to operate under normal environmental terms and conditions, as set out by the relevant Armenian authorities. Lydian has all the necessary permits to undertake exploration work at Amulsar. Additional permits will be required as the project advances from exploration to construction and onwards to production. For details, refer to Section 20.7.

5.0 ACCESSIBILITY, CLIMATE, LOCAL RESOURCES, INFRASTRUCTURE AND PHYSIOGRAPHY

The following property accessibility, climate, local resources, infrastructure and physiography descriptions are taken from the NI 43-101 report dated the 19th May 2011 mentioned in the Introduction of this report. 5.1 Access The Amulsar area is located some 170 km by sealed road and 15 km by unsealed track to the southeast of Yerevan. The license area straddles the boundary between Vayots-Dzor and Syunik provinces and incorporates part of the main highway south from Yerevan into Iran. 5.2 Climate The weather is highland continental with generally hot summers and cold winters. Temperature varies significantly depending on altitude. Mean summer temperatures are reported as 25ºC, with mean winter temperatures being around minus 4ºC. Annual precipitation is low, with an average in the order of 700 mm. Snow falls across higher ground during the winter months and can remain from early November through to late March. Because of the altitude, Amulsar Mountain is snow covered for the winter months. Until all season roads are constructed, snow plows are purchased and routine maintenance is ongoing access is generally possible only from March to November and access for heavy machinery is confined to the period from May to October/November. 5.3 Resources and Infrastructure Infrastructure in the main areas of Armenia is generally well developed, with a good road and power network except in more remote regions. A high-tension power line transects the southern limits of the license (Figure 5.1). Most areas have mobile phone coverage. The capital, Yerevan, has a high standard airport, with regular flights to many international centres.

Figure 5.1 - Physiography and Infrastructure in the Vicinity of the Amulsar Licenses

Green- Amulsar Mining License; Red-Saravan license; Blue-Gorayk license 5.4 Physiography Armenia covers an area of 29,800 km², with much of the country being mountainous. Elevations are more than 1,500 m in most places, rising to a maximum of 4,090 m. Most of the mountainous areas are covered by scrub vegetation, with some forested zones. There are a number of fertile river valleys. The country lies within a seismically active zone, with some areas having a high risk of major earthquakes. The last major quake was in 1988 in northern Armenia. The Amulsar area is also seismically active with the most recent destructive earthquake being recorded in September 1931 at the township of Sisian some 30 km to the southeast of the prospect area. Destructive earthquakes have also been recorded in the ancient city of Vayk, some 20 km to the west. The core of the Amulsar area comprises a mountainous terrane, an approximately 7 km long northwest-southeast trending ridge which reaches a maximum altitude of 2,988 m. The mountainous area around Amulsar is quite rounded and, with

6.0 HISTORY

The following history descriptions are taken from the NI 43-101 report dated 19th May 2011 mentioned in the Introduction of this report. 6.1 Armenian Mining and Exploration - General History Due to its location within a tectonically active collision zone between the Arabian and Eurasian plates, Armenia has been endowed with a range of mineral resources, particularly large, porphyry-style copper-molybdenum deposits, as well as many polymetallic and gold bearing vein systems. Large scale metal production began in the early 19th century with the opening of the Alaverdy and Kapan polymetallic mines. More recently, in the 1950’s, the Zangezur Copper Molybdenum Combine, developed the world-class Kadjaran deposit in the south of Armenia, which produces 3 percent of the world’s molybdenum output. The dissolution of the Soviet Union, coupled with low metal prices, severely disrupted Armenia’s mining industry in the 1990’s, but a new legislative framework and improved market conditions led to a significant upturn over the last few years, prior to the recent downturn in metal prices. Metal production comes from the Kadjaran (Cronimet) and Agarak (GeoProMining) copper/molybdenum porphyry deposits and the Kapan vein-type polymetallic deposit (Dundee Precious Metals) in the south and the Shahumyan polymetallic deposit in the north, although these have been adversely impacted by the metal price slump of late 2008 and 2009. Gold deposits known to date are primarily hosted in veins and brittle shear structures - the Zod gold mine (GeoProMining) in eastern Armenia is an example of the latter, but gold is also present as an accessory mineral in some polymetallic deposits. Other foreign exploration companies active in Armenia include Global Gold, Caldera Resources and Anglo African Minerals. 6.2 Amulsar History

The Amulsar region was initially identified by the Armenian Soviet Expedition in 1936 to1937 as an area of “secondary quartzite” which was deemed to host potential as a silica resource. Work aimed at testing the potential of the silica resource commenced in 1946 with the development of small-scale exploration adits. This work concluded that the alunite content of the silica was too high (up to 25%) and that, as such, the project was of no interest as a source of quality silica. Further work in the early 1960’s identified the “secondary quartzite” as metasomatic in origin, developed due to the replacement of intermediate composition volcanic rocks (known regionally as the Amulsar Suite). Some 300 m of tunneling and 640 m3 of trenching were also completed during this time, mostly on the north-eastern side of the ridge. Testing of a bulk sample concluded that the silica was of sufficient

quality for the production of low grade glasses. Volumetric calculations made during this time estimate indicated some 360 million tonnes of secondary quartzite rock at Amulsar. Research work by the Soviet Expedition continued at Amulsar during the period 1979 to 1982. This work was focused principally on understanding and mapping the alteration zonation across the area. Silica reserves at Amulsar were never entered onto the Republic of Armenia State Balance and no further exploration or research work has been conducted by the Soviet Expedition in the area since 1982.

7.0 GEOLOGICAL SETTING The following geological setting descriptions are taken from the NI 43-101 report dated 19th May 2011 mentioned in the Introduction of this report. 7.1 Regional Geological Setting

The following section is taken from an internal Lydian report detailing the geological setting at Amulsar.

The Amulsar high sulphidation gold deposit is situated in central Armenia and is hosted in the Upper Eocene to Lower Oligocene calc-alkaline magmatic-arc system that extends north-westward through southern Georgia into Turkey and south-eastwards into the Alborz-Arc of Iran.

Volcanic and volcano-sedimentary rocks of this system comprise a mixed marine

and terrigenous sequence that is interpreted to have developed as a near-shore continental arc along the southern margin of the Eurasian Plate and at the northern limit of the Neo-Tethyan Ocean. The Neo-Tethyan closed and subduction ceased along this margin in the Early Oligocene when a fragment of continental crust, known as the Sakarya continent, collided at the trench axis and accreted with the Eurasian plate. The location of Amulsar within this arc is shown below in Figure 7.1.

yellow circles indicate gold dominant resources. 7.2 Local Geologic Setting

The oldest rocks within the Saravan and Gorayk license areas are siliciclastic marine sediments found in the north-west of the Saravan License area and interpreted to be Upper Palaeocene in age. These comprise westerly dipping (approx. 30°) coarsely bedded, polymictic, matrix supported conglomerates with occasional Bivalve fossils preserved. Clasts are sub-rounded and composed of variable intermediate composition volcanics. The lithology is interpreted as having formed in a near shore, relatively high-energy marine shelf environment (Figure 7.2A).

These conglomerates are overlain by a thin (less than 20 m thick) tuffaceous unit that hosts at least two separate known zones of carbonate vein-style base metal

Page 51: LYDIAN INTERNATIONAL, LTD. · 2015. 6. 15. · 1. I am an Independent Mineral Process Engineering Consultant and contributed to a Report entitled “Lydian International, Ltd., Development

mineralization. Veins are relatively narrow (30 mm to 200 mm wide), and the largest identified zone of veining is less than 5 m in width, the along-strike and down-dip extent of which is unknown. The dominant ore mineral is copper-bearing azurite and minor lead-bearing galena (refer to Figure 7.2 right hand image).

license area. (Right Image) - Carbonate vein-style base metal mineralization (Sample No. AR2777: 1805 g/t Ag, 14% Cu, 1.94% Zn).

These conglomerates and tuffs are uncomformably overlain by an Upper Eocene

age, thick succession of northward dipping (approx. 10°) dark-grey, monolithic, sub-aqueous, basalt-andesite composition volcano-sedimentary breccia units that grade into increasingly coherent extrusive volcanic lava flows which exhibit autoclastic "quench" textures higher in the sequence, formed as a result of extrusion in a sub-aqueous environment (Figure 7.3).

There are numerous basaltic sills less than 2 m in thickness that can be traced

for greater than 1 km along bedding planes within the sequence. These volcanic/volcano-sedimentary units cover a large area and can be seen surrounding Saravan Village and to the north-east of Gorayk Village.

The bedded lithologies detailed above were subsequently intruded into by a large, hypabyssal andesite dome that dominates the Amulsar Mountain, with associated lava flows that overlie the bedded units at lower elevations to the north and west. The intrusion has a fine to medium grained porphyritic crystalline texture, with an aphanitic groundmass and plagioclase phenocrysts ranging from less than 1 mm to 3 mm.

Figure 7.6 - B - B’ cross section showing geology from Artavasdes to the eastern and northern

slopes of Tigranes.

The Amulsar gold deposit itself is situated along the ridge-top of the mountain, hosted in a sequence of Eocene-Oligocene volcanic andesites and volcaniclastic rocks that overlie the lithologies detailed above and dip at approximately 20° to the north east. These rocks have commonly been affected by multi-stage acid-leaching hydrothermal alteration events which have produced widespread texturally destructive silicification and hence it is often very difficult to identify any primary composition or texture and there is no known unaltered examples. Poorly sorted, coarse grained (5 mm to 200 mm), matrix supported, sub-angular clasts are characteristic of the volcaniclastic units which are most commonly found lower on the flanks of the deposit at Erato and North Erato; flow-banding is a common feature within the volcanic units that dominate the Tigranes and Artavasdes areas. These units were later intruded by a large, irregular sill-like feldspar-augite porphyritic andesite, with feldspar phenocrysts less than 5 mm within an aphanitic matrix.

Episodic fault activity and high level magmatism has been responsible for the

development of multi-stage phreatic and hydrothermal breccias that form large bodies throughout the deposit. The character of these breccias is variable across the deposit, although it appears that they formed predominantly during two separate events. The relative ages of these breccias is best determined by the alteration of matrix and their component clasts, and cement type. The oldest breccias are pre-mineralization, altered to massive silica to silica clay, grey in color, and monomictic to polymictic; they are also relatively competent with poor permeability due to the strong silica massive cement. The second phase of brecciation and alteration appears to have occurred shortly after the intrusion of the feldspar-augite porphyritic andesite sill, and was potentially contemporaneous with gold mineralization. These breccias can occur as monomictic where found on the margins of the porphyritic andesite sill, yet are predominantly polymictic, poorly sorted with rounded ‘milled’ clasts, although jigsaw breccias are occasionally present to a much lesser extent. The discriminating feature of these second stage breccias is the hydrothermal fluid derived cement composed of hematite dusted silica and having a ‘honey’ brown color, there is also a close association with gold mineralization and silica-alunite alteration. Clasts of the early ‘grey’ silica massive altered lithologies and occasionally clasts of porphyritic andesite can be found within these second phase breccias. Associated with this second brecciation was the formation of massive sulphide cemented hydrothermal breccias and veins with clasts of

early ‘grey’ silica altered volcanics. These have been entirely oxidized by supergene processes, altering the massive sulfides to hematite-jarosite cement.

The porphyritic feldspar-augite andesite is interpreted to have been emplaced post the first silica alteration and breccia event but prior to the second and gold mineralization. This inference can be made because clasts of the early ‘grey’ silica altered lithologies are found within the porphyritic andesite (Figure 7.7 Left Image), yet it is brecciated by the second stage breccias and localisation of higher grade gold mineralization often occurs at its boundaries due to its capacity as an impermeability barrier to hydrothermal fluids.

At lower elevations than the outcropping Amulsar deposit, unaltered Quaternary basalt flows seen to the north, east and south, overlay the Lower Tertiary volcano-sedimentary and intrusive rocks.

Structures represent a very important control on gold mineralization throughout the Amulsar deposit, hence surface and down-hole mapping of structures has been carried out across the project area, and has been integral in the generation of the geologic and resource models. From Lydian’s work it is clear that both northeast and northwest striking, steeply dipping trends show most strongly at Tigranes and Artavasdes, although the orientations are not tightly constrained and show a continuation of possible strike orientations between northeast and west-northwest. At Erato the dominant structural trend observed in approximately striking 010° and dipping steeply to the west, however down-hole and surficial structural data is limited at present. High grade structures are seen as faults, veins, and fractures, with no significant orientation controlling higher grades than the other. 7.4 Alteration

There is no one obvious alteration facies that hosts the gold at Amulsar. This relates in part to the fact that the gold resides in late structures that cut lithologies and units that have been affected by multiple alteration events. Silica is a universal component of the gold mineralized intervals, but the high grade gossans often lack any alteration characteristics that can be recorded other than quartz and alunite, hence the strong alunite association.

7.5 Sequence of Alteration Events

Lydian proposes the following sequence of alteration events at Amulsar;

▪ The emplacement of a high level intrusive into the volcanic pile and generation of copious amounts of hot water resulted in extensive clay alteration, followed closely by silicification of ledges within the core area with surrounding clay alteration remaining.

▪ Silica-alunite alteration with the generation of second phase breccias and the

introduction of sulphide (dominantly pyrite) gold-silver ± copper mineralization. The porphyritic feldspar-augite andesite underwent argillic alteration in which the plagioclase feldspar phenocrysts are replaced by kaolinite, the augite phenocrysts by pyrite and the groundmass by fine-grained quartz. Outwards from the silica – silica-alunite ledges, the groundmass quartz content of the kaolinised rock decreases, forming an impermeable barrier and causing ‘ponding’ of mineralization along the contacts.

▪ Later supergene processes caused the oxidation of sulphide material within

silica altered bodies to depths of over 200 m, converting sulphides to hematite and jarosite and liberating gold and silver. The massive quartz bodies are normally a product of wholesale silicification. Where the quartz displays a vuggy texture, it is commonly due to supergene oxidation and removal of pyrite grains rather than to the hypogene leaching of silicate minerals. The sulphur released is believed to have caused the leaching of copper, removing it from the system and explaining the complete lack of copper mineralization within the area drilled so far.

The alteration observed at Amulsar appears indicative of being in the deeper parts of the high sulphidation epithermal system. This hypothesis is supported by the presence of steeply dipping, structurally controlled silica ledges, and the lack of shallowly inclined silicified horizons generated at paleo-water tables and/or powdery advanced argillic alteration formed in the steam-heated environment between paleo-water tables and paleosurfaces. Also the observed presence of wormy (elsewhere termed gusano texture) pyrophyllite replacement textures that is formed at temperatures of over 240°C and is common near the base of silicic lithocaps, and in turn over the top of shallow porphyry systems (e.g. Yanacocha, Tucari, and Tantuatay).

8.0 DEPOSIT TYPES AND MINERALISATION The following deposit types and mineralization descriptions are taken from the NI 43-101 report dated 19th May 2011 mentioned in the Introduction of this report. Gold mineralisation at Amulsar is seen to have been a late event in the development of the deposit; hence the spatial distribution was therefore controlled by all alteration events and structures. Gold occurs within limonitic zones after the oxidation of sulphide material, and three dominant controls on the localisation of gold mineralisation have been defined:

▪ The argillic altered (kaolinised) porphyritic andesite formed an impermeable barrier to mineralising fluids, and caused ‘ponding’ of higher grade mineralisation along the contacts, often appearing as thick, leached and ‘gossanous’ zones. This is present throughout the deposit: in the Tigranes area the contacts are irregular yet generally steeply dipping, whereas in parts of Artavasdes and at Erato, the argillic altered porphyritic andesite forms an overlying ‘cap’ which results in the localisation of sub-horizontal mineralisation within siliceous units below.

▪ Faults and fractures provided conduits for the introduction of gold mineralising

fluids, resulting in high grade ‘gossanous’ veins and clay-gouge dominated faults. These often form broad corridors of numerous, closely spaced high-grade structures, and can also be seen to cross-cut the argillic altered porphyry andesite, and allow for discrete zones of mineralisation; such as between Tigranes and Artavasdes where mineralisation is seen to be continuous between the two areas along such structures.

▪ Porous and permeable lithological units (hydrothermal breccias, volcaniclastic

breccias, and occasional leached/vuggy volcanics) allowed for the lateral migration of mineralising fluids away from structurally controlled conduits, and formed large tonnages of lower grade material. This is seen particularly well in Erato, where weaker silicification has preserved the intrinsic permeability of the original lithologies and resulted in broad areas of consistent gold mineralisation.

The presence of silver mineralisation is as yet poorly understood, and does not appear to correlate strongly with gold grades. Silver values at Amulsar average 2 to 5 g/t silver, although can reach greater than 100 g/t silver within narrow intervals. Copper and other base metal mineralisation is virtually absent from the areas drilled so far, although this is present within carbonate veins from lower stratigraphic elevations in the west of the Amulsar license area. A small silver mining project adjoins the Amulsar licence to the northwest, exploiting argentiferous galena hosted in a structurally controlled vein. This deposit is also located at a lower stratigraphic elevation to the Amulsar deposit.

Lydian have indicated that genetic similarities exist between the mineralisation at Amulsar and Gryphon Gold Corporation’s Borealis gold project in Nevada, USA, however the alteration patterns differ in detail. Both are high sulphidation epithermal gold deposits which have higher grade, structurally controlled mineralisation surrounded by a lower grade, strata bound halo of mineralisation. A generic type section of the Borealis deposit can be found in Figure 8.1.

9.0 EXPLORATION

The following exploration information is taken from the NI 43-101 report dated 19th May 2011 mentioned in the Introduction of this report.

The work program at Amulsar has been designed to define the scale of the epithermal system and the extent and grade of the gold mineralization within that system. Drilling in 2008 was focussed on defining the main body of the Amulsar deposit to satisfy regulatory requirements to gain a mining license. Drilling in 2009 was undertaken as a step out program, surrounding the previous drilling and to test the extents of the Amulsar deposit. Drilling in 2010 was focussed on infill drilling at Artavasdes, Tigranes and Erato, to upgrade some parts of the resource to higher categories. This work is summarised in the Table 9.1 below.

10.0 DRILLING The following drilling information is taken from the NI 43-101 report dated 19th May 2011 mentioned in the Introduction of this report 10.1 Drilling Lydian has carried out two types of drilling at Amulsar during 2010. Reverse circulation (RC) and diamond (DDH) drilling was undertaken. A total of 49 core holes and 127 RC holes drilled, totalling 24,539 m, comprising 7,502 m of diamond drilling and 17,036 m of RC drilling. Drill-Ex International was responsible for all of the drilling on site during this time. Drill holes were angled and were drilled either towards the northwest or southeast (in the northern area) and southwest or southeast (in the southern area) to optimize the intersection angle with the steeply dipping mineralized zones. Holes were laid out on northwest-southeast grid lines. In central areas, at Tigranes and Artavasdes drill holes were spaced 40 m apart, with holes generally drilled at 40 m intervals along these sections. Hole spacing became larger towards the edges of the deposit. Drilling at Erato was based on a rough 80 m by 80 m grid. Hole depth generally ranged from 100 to 250 m but most holes were drilled to approximately 140 m down hole depth. The diamond drill holes were usually drilled at PQ diameter for the first 20 m to 30 m and then reduced to HQ diameter. Standard practice during the drill program was to survey all drill collars and to carry out down hole directional surveys. In addition, during drilling, regular orientation tests were carried out using the Ezy Mark system to help establish the true dip and strike of the rock units and vein/fracture systems. Down Hole surveying was conducted using a Globaltech Pathfinder system, no deviation issues were identified. After logging of rock chips or drill core, samples were taken, generally at one-meter intervals throughout the entire hole, and dispatched for multi-element analysis and gold assay. A total of 7,082 samples were assayed from drill core, as well as 16,962 rock chip samples from RC holes. Analysis for silver was also undertaken; however samples were in some instances composited up to 6 m to reduce costs and limited QA/QC data was acquired during analysis for silver. If Lydian is interested in including silver assays as part of future MREs then CSA recommend re-sampling at original intervals, with representative QA/QC sample support. Silver results were not reported as part of this MRE. Drill results, lithology interpretations and assay results have further defined the two previously identified zones of gold mineralization, Tigranes and Artavasdes. Increased drilling to the north has defined an additional area of gold mineralisation, Erato. Many of the holes show a pattern of relatively widespread low grade mineralization (generally less than 1g/t gold) within silica-altered zones (sometimes with

43mDepth(approx.1g/t gold) Based on drilling to date, the Amulsar deposit remains open at depth. The Artavasdes area remains open along strike and to the south. The area to northeast of Tigranes has untested potential on the extensions of the main northeast trending mineralised faults present on Tigranes. The Erato area remains open in all directions and limited drilling has occurred at the Erato North target. Further infill drilling at Tigranes and Artavasdes is required in order to increase the geological and grade continuity such that currently defined resources can be upgraded to higher resource categories. Step-out drilling along strike and to the east of Artavasdes area should be considered in order to investigate mineral continuity in areas of sparse drilling. Infill drilling is required at Erato in order to adequately confirm geological and grade continuity such that the defined resource can be upgraded to a higher resource category. Drilling to further investigate mineral potential at Erato north along with other exploration targets should be undertaken to assess the likelihood of augmenting the current resource base with resources from these areas.

10.2 Planned Drilling for 2011 Lydian has planned drilling totalling 45,000 m and aims to complete at least 30,000 m during the 2011 drill season, comprising 15,000m of DD and another 15,000 to 30,000 m of RC drilling. Planned collar positions, compared to historic drilling are displayed in Figure 10.3. This total excludes holes planned for metallurgical testwork, hydrological monitoring and pump testing, geotechnical investigations, and sterilization drilling planned as part of the planned BFS. Lydian states their drilling objectives as;

▪ Infill drilling - to close off gaps within the current Indicated resource and to upgrade Inferred portions of the resource that are located within the current pit design. A significant amount of this drilling will be in boulder field areas which have not been accessed previously for drilling.

▪ Step out drilling - to test the lateral extensions of the mineralised faults that

have been identified in the current model and to upgrade the classification of Exploration Potential Material.

▪ Deep drilling - to test the depth extents of mineralisation below current drilling. ▪ BFS drilling - to obtain core for geotechnical, hydro-geological and

metallurgical requirements for the BFS. Lydian consider the planned drilling, along with improvements in wireframe models and planned improvements to QA/QC procedures should allow the upgrade of a portion of the current resource to Measured Resource, to be considered as part of the next resource update. CSA offers the following comment on planned drilling;

▪ The current plan is ambitious, but should be achievable as long as Lydian can source enough drill equipment and that the equipment doesn’t suffer from any major breakdowns, or unexpected delays.

▪ Planned infill drilling is considered sufficient to support an extended Indicated

Resource within the current planned pit.

▪ Step out drilling is sufficient to further define current Exploration Potential material, with the possibility for some to be upgraded into an Inferred category.

▪ Exploration holes are focussed on defined targets from region exploration

work and should investigate the potential for mineralisation in these areas.

CSA cannot say that the planned drilling will increase, or upgrade the current resource estimate, or its classification. This is entirely dependent upon the results of the planned drilling.

10.3 Channel Sampling A total of 1,092 m collected from 43 channels from across the Amulsar area. Channels were cut by a two bladed angle grinder to approximately 2 cm depth, Figure 10.4. Perpendicular cuts were made to facilitate sampling which was undertaken using a hand chisel and a hammer. Samples were collected below the channel in a sample bag, Figure 10.5. Samples were delineated according to the geological and alteration styles identified.

Drill hole collars are represented by small black dots 10.4 RC and DDH Sample Recovery Investigation During the 2008 drill campaign core recovery averaged approximately 91 percent, with RC recovery close to 100 percent. RC and DD recovery during 2009 decreased to 72 and 93 percent respectively. Recoveries from the 2010 drill campaign have increased with diamond core recovery at 96 percent and RC recovery at 89 percent. CSA undertook a review of RC sample recovery versus assay grade to assess this relationship and to determine the level of confidence that can be applied to the representivity of samples within mineralized zones. It was observed that the majority of samples within the interpreted domains exhibited a range of recovery values between 60 and 120 percent. Very low sample recoveries dominantly occur in near-surface areas, to a depth of 10 m. Sample recoveries exceeding 100 percent may occur at down-hole depths corresponding to the end of a drilled run, and may be due to sample accumulation in the cyclone.

Correlation plots of grade versus recovery within each of the 12 interpreted domains are contained in the May 19, 2011 43-101 Technical Report mentioned in the Introduction. It was observed that a broad spread of recoveries occurred within each domain. However the majority of material was collected with recoveries greater than 60 percent. Overall there does not appear to be a strong trend of >0.2ppm gold samples (resource grade) exhibiting poor recovery. However, clearly samples that have been affected by poor sample recovery are present within the mineralized zones, and to some extent the representivity of sample grades may be brought in to question and some grades may be overstated or understated, to an unknown degree. As part of future resource development, Lydian should undertake a detailed investigative study of the RC sample recovery versus grade relationship, focusing on an analysis of spatial representivity and drilling practices, as well as investigating whether sampled material could have been preferentially lost during drilling. Overall CSA considers that the effect of poor sample recovery in mineralised domains to be minimal. 10.5 Twin Hole Investigation Lydian under took a twin drill hole investigation during exploration and resource drilling at Amulsar. A total of 14 RC and DD holes were twinned, see Table 10.3.

Table 10.3 RC and DD Twinned HolesRC DD

A review of the global data populations for RC and DD data was undertaken and is shown in the following P-Plot (Figure 10.7) and Histogram (Figure 10.8) of gold distribution within the 0.3 g/t wireframes supplied by Lydian. A review of the local data, using twinned drill hole data supplied by Lydian was also undertaken. Diamond drill hole data was composited to 1m intervals (or 2 m intervals in the case of holes DDA-042 vs. RCA-144 and DDA-045 vs. RCA-156 where RC data was collected in 2 m samples).

Figure 10.7 - Probability plot of RC and DD assay grade within Structural wireframes

Figure 10.8 - Histogram of RC and DD assay Data within Structural wireframes

CSA believes that there is no conclusive evidence, nor any suggestion, that RC assay data consistently understates or overstates gold grade as compared to diamond core assay data, on a global or local scale. There are no specific grade ranges that show difference. CSA conclude that one or other sample type does not introduce bias. When the twin hole data (RC V DDH) was reviewed and, accounting for shift where appropriate when comparing intervals between holes, do not see any significant understating of RC as compared to DDH. High grade intervals in RC are replicated in twin DDH and low grade too. Any observed differences, which we don't consider to be significant, are more than likely related to natural grade variation and the nugget effect. Given that there appears to be no observed bias with either DDH and RC data, and recent average RC sample recovery of 89 percent appears not to understate or overstate grade, CSA considers both data sets, exhibiting the average recovery stated above, to be acceptable for use in resource estimation work.

10.6 Sample Density Analysis Density determination at Amulsar has progressed through a number of phases. Density prior to 2009 was estimated using data from two studies, and a total of 55 samples. The first data set was comprised of 13 half core samples from 2 diamond drill holes representing a number of lithologies and alteration styles. SG was determined using hydrostatic weighing and waxing of the samples, testwork was undertaken by Geoid, an Armenian company specializing in mineralogical studies. Results of this testwork produced SG’s that ranged between 2.17 g/cm3 and 2.54 g/cm3, with an average of 2.38 g/cm3. The second study, undertaken prior to 2009, comprised 42 half core samples of a uniform 10cm length, collected at various depths from 13 holes. Samples covered a range of lithologies and alteration types encountered at Amulsar and improved spatial representivity. SG was determined by ALS Chemex using procedure OA-GRA08 which, depending on the nature of the sample utilised paraffin wax as a sealant. The specific gravities obtained from this work ranged from 1.96 g/cm3 to 2.68 g/cm3, with an average of 2.41 g/cm3. Testwork in 2009 was undertaken by Newmont on a total of 241 samples from a range of material types. Samples were selected from the 2008 and 2009 diamond core, and were grouped according to logged alteration and lithology. SG was determined using the paraffin wax sealant method, producing a weighted average SG for each alteration type. Lydian undertook a review of SG samples during 2010 as the geological model was developed, grouping them into dominant rock type; breccias, volcanics and porphyry andesite, and producing average SG values according to rock type, Table 10.4.

Table 10.4 SG Values According to Rock Type Rock Type Bulk Density (g/cm3)

Porphyritic Andesite 2.24 CSA reviewed the SG data available and concluded;

▪ The data was not affected by any outliers (Figures 10.9, 10.10 and 10.11). ▪ There was no correlation between SG and gold grade (Figure 10.12). ▪ SG data collected adequately covers the resource area at Amulsar (Figure

10.13).

SG values were assigned to the blocks within the mineral resource estimate according to rock type. Lydian has not collected any SG samples following the Newmont review in 2009. The current SG dataset is well spaced throughout the deposit and represents the dominant rock types, however when compared to the total sample population the data set is small. CSA recommend that Lydian continue to collect SG information at a 1:20 ratio during drilling to further refine the SG value for the deposit. 10.7 Sampling Method and Approach 10.7.1 RC Drilling RC samples are taken every one metre down the hole by collection of rock chips at the cyclone on the RC rig. Lydian state that the hole is normally air-flushed out after each metre to avoid contamination of the following sample. At the drill site the samples are weighed, logged, bagged, labelled and sealed, prior to transporting to the Amulsar Camp for splitting (Figure 10.14). Samples are split to produce two 1.5 to 2 kg samples, one for assay and the second to be kept as an archive sample. The riffle splitter is cleaned between samples by brushing and the use of compressed air. Individual weights for the entire 1 m sample, and the final sample were recorded in order to recalculate any over-/under-estimations. These samples are transported to the Lydian sample preparation facility at Gorayk for insertion of QA/QC samples into the sample batch and dispatch to the assay laboratory. Archive RC samples are stored at the Gorayk facility.

10.7.2 DD Drilling Geological and geotechnical logging are carried out on the core at the Amulsar camp. Once logged sample intervals are marked up on core boxes prior to the core being transported to the sample preparation facility at Gorayk. Sample lengths can vary, depending on geology and other factors, but are typically in the range of 1 m. Current practise dictates that core is pushed to one end of the core box and sample marks are made onto the core tray. CSA considers this practise to be inadequate, allowing for human error when sampling and would recommend that sample intervals be marked on core prior to cutting and sampling, with either a china graph pencil or white paint marker. Lydian systematically photographs all core prior to sampling. Historic logging has been of a high quality, however due to the nature of the mineralisation it is difficult to identify the two mineralisation styles from rock type alone. CSA would recommend that logging of percent porosity should be undertaken to assess whether this can be used as an indicator of mineralisation style along with structural measurements and may go some way towards identifying mineralisation types during logging and prior to the receipt of assay results.

11.0 SAMPLE PREPARATION, ANALYSIS AND SECURITY The following sample preparation, analysis and security descriptions are taken from the NI 43-101 report dated 19th May 2011 mentioned in the Introduction of this report. Lydian’s sample preparation facility is located in the village of Gorayk to the southeast of the Amulsar project. The facility includes core saws, a core crushing unit, and storage for both core boxes and archive samples. Prior to the establishment of their own crushing facility, all Lydian rock and half core samples from the Amulsar project were bagged, labelled and sealed on site and transported to the ALS Chemex analytical laboratory in Romania for sample preparation and gold assay. In mid-September 2008 Lydian installed its own crushing facility at Gorayk. This comprises an ALS Chemex mobile containerised unit, consisting of a drying oven, jaw crusher and riffle splitter. The crusher can crush split core to 90 percent less than 2 mm and also allows Lydian staff to manage on-site, the coarse rejects of the crushed diamond half-core. The crusher and riffle splitter are cleaned between samples by brushing and the use of compressed air. Lydian employ an experienced local analytical laboratory operator to run the unit and uses this facility to carry out preliminary preparation of its rock and half core samples, allowing it to dispatch 1 kg crushed samples to the ALS Chemex laboratory in Romania. In mid-September 2010 the crusher suffered a mechanical breakdown and was not in operation during CSA’s May 2011 visit. Lydian has ordered a new containerised sample preparation unit from ALS Chemex in Johannesburg which is due for delivery in June 2011 and will replace the existing unit. The new sample preparation laboratory will contain two crushers and a rotary splitter divider which will allow Lydian to reduce the sample size shipped for assay to 200 g to 250 g which will significantly reduce sample shipping costs. Core samples are split by diamond saw in two equal halves - one half is returned to the core box for future reference, while the other half is bagged, and oven dried prior to crushing. An assay sample and an archive sample are collected from the splitting of the crushed core. Diamond core duplicate assays are produced as an additional split sample. Since the breakdown of the crusher in September 2010 half core has again been sent to ALS Romania, with quarter core being used for duplicate samples. On arrival in Romania ALS gives the samples a batch code and weighs all samples. Each sample is then logged in and ascribed an individual bar code. Rock samples not already received in crushed form are subject to fine crushing to 70 percent of material passing 2 mm. Samples are split using a riffle splitter and a 1,000 g split is then pulverised to 85 percent passing 75 µm. A 50 g sub-sample is analysed at the Romanian laboratory for gold by fire assay, with an AA finish. The remainder of the split sample is sent by ALS Chemex to its sister

laboratory in Perth (pending registration to ISO 9001:2000) or Vancouver (ISO17025), where the sample is subjected to a four acid digest, followed by analysis for 33 elements by ICP-MS (ALS ME-ICP61 package). Additional analyses are undertaken for samples returning assays returning grades above the detection limit (typically silver, zinc and lead). All ALS Chemex laboratories operate in compliance with ISO17025. ALS Chemex carries out regular checks by duplicating analyses for several samples, and by inserting its own blanks and standards as part of its own Quality Management System. Lydian prepares its samples and dispatches these to ALS Chemex with the inclusion of blanks, duplicates, and standards of different concentrations with random numbering.

12.0 DATA VERIFICATION The following data verification is taken from the NI 43-101 report dated 19th May 2011 mentioned in the Introduction of this report. Nerys Walters, Senior Geologist, CSA Global, visited the Lydian core storage facility at Gorayk village during May 2011 to view drill core from the Amulsar prospect and to review geology, sampling procedures and assay results. Core from holes DDA-030, DDA-034, DDA-035, DDA-036, DDA-044 and DDA-047 were examined. From a study of the assay results for these holes it was clear that the highest gold grade intercepts are directly related to massive clayey limonite zones, while wider, lower-grade sections relate to pervasively silicified and brecciated zones, sometimes with limonitic matrix. Miss Walters also visited the Amulsar site, where she located and measured the collar positions for holes RCA-223, RCA-280 and DDA-044. They were surveyed in using handheld GPS along with the survey Trig beacon at the top of Artavasdes. A brief review of the geology was undertaken but thick snow cover prohibited review in some areas. Observation of diamond drill practices (Figure 12.1) were undertaken on the lower slopes of Amulsar. CSA considers Diamond drill practices to be of a high standard with a well organized and safe work environment, drilling was undertaken by well-trained competent drillers and offsiders. No further on-site verification has been undertaken, and it has been assumed that all processes and procedures that were reviewed and found to be adequate during the previous review remain current.

Figure 12.1 - Drilling being observed during the CSA site visit (2011)

In preparation for the forthcoming BFS, Lydian engaged Wardell Armstrong Ltd. in 2010 to review all Diamond and RC drilling, sampling and assaying QA/QC procedures for assayed core and metallurgical test work samples as well as comparing results of twinned RC and core drill holes. Wardell Armstrong concluded the following: “With regard to the exploration programme itself, WAI is very satisfied with all aspects of the work from the planning, execution and results derived therefrom. Furthermore, Lydian has used international best practice at all times to undertake the drilling and ancillary exploration works, also made easier by the selection of a highly competent drilling contractor in Drill-Ex International” (Newall, 2010). 12.1 QA/QC Introduction Industry standard assay QA/QC control was implemented by Lydian during exploration and resource development activities in 2008, these practices are still current.

In addition to the QAQC data reviewed below, at the time of reporting Lydian were about to submit approximately 1,200 pulp samples, from 2006-2010 RC and Diamond drilling, to Alfred H Knight in Alaska. Lydian states that these samples come from holes drilled across the resource area and have been selected at a rate of 1 in 20 (5%) for assay greater than 0.2g/t gold and 1 in 40 (2.5%) for assays less than 0.2 g//t gold. A similar programme will be undertaken at the end of the 2011 drill programme. CSA has not had access to this data and as a result cannot comment on the representivity of the sample batch. In addition to reviews undertaken as part of previous resource work in 2009, CSA conducted a review of QA/QC data from RC and DDH sampling undertaken during 2010. A summary of QA/QC data is tabulated below.

Table 12.1 2010 Assay QA/QC Summary 

  During the 2010 RC DD sampling program a total of 3,646 QA/QC samples (comprising 2% blanks, 3% duplicates and 5% certified reference samples) were generated, which is considered representative of drilling and spatially representative. CSA believes the proportion of blanks and duplicates to be acceptable. 12.2 RC QA/QC Control Plots for RC QA/QC data collected during the 2010 drilling campaign is contained in Figures 12.2 to 12.10 below,

Figure 12.10 - RC Assay QA/QC – CRM G307-2 (1.08ppm)

12.3 RC QA/QC - Conclusions Results from the analysis of blank reference samples shows less than 1 percent of samples (2/470) returning grades greater than 3× the detection limit (greater than 0.015 ppm gold) which is considered acceptable. Sample assays adjacent to these outliers were checked for the possibility of contamination during sample preparation. Adjacent samples were not mineralized. CSA recommends that during future drilling campaigns the primary laboratory be audited to ensure adequate sample preparation practices are adhered to. Results from the analysis of duplicate sample assays suggest a close correlation between the original assay and the duplicate assay (correlation coefficient = 0.98). The scatter graph in Figure 12.3 shows that duplicate results exhibit acceptable levels of accuracy and precision. On the whole, results from the submission of standard reference material suggest assaying accuracy to be within acceptable limits. The control plots show that 99 percent, 100 percent, 98 percent, 100 percent, 99 percent, 98 percent and 93 percent of samples returned values within an acceptable tolerance of plus or minus 10 percent for CRM’s 300-7,303-2,398-6,900-6, 904-8, GLG304-1 and 307-2 respectively. Although the majority of returned values fall within acceptable limits, CRM 300-7 and 398-6 show a slight bias towards under-reporting and CRM 304-1 and 302-2 show a slight tendency towards over reporting. There appear to be no significant, non-random patterns to any dataset other than weak to moderate cyclicity within acceptable limits. It is probable that this cyclicity is related to equipment calibration. Outliers are present in the control charts, notably for CRM G300-7, G398-6, G904-8, GLG 304-1 and G307-2. Review of these outliers indicates that they may be

due to incorrect labeling of the CRM, resulting in some confusion in expected values. CSA Recommends that Lydian reviews systems in place for the insertion of CRM samples to minimize these errors in future. The results of standard analysis suggest no significant bias exists and assay results may be considered reliable. CSA notes that although flagged, outliers have not been investigated by Lydian at the time of reporting. CSA recommends that Lydian reviews systems currently in place that manage the insertion of CRM samples to minimize these errors in future. Current blank samples are sourced from alluvial sand for RC samples. Although no significant contamination has been identified CSA would recommend that Lydian source certified blank material to align their procedures with industry best practice. 12.4 DDH QA/QC A total of 47 diamond holes have been drilled in 2010. Control Plots for DDH QA/QC data collected during 2010 is contained in Figures 12.11 to 12.19 below.

Adjacent samples were not mineralized. CSA recommends that during future drilling campaigns the primary laboratory be audited to ensure adequate sample preparation practices are adhered to. Results from the analysis of duplicate sample assays suggest a reasonable correlation between the original assay and the duplicate assay (correlation coefficient = 0.83). The scatter graph in Figure 12.12 shows duplicate results to exhibit acceptable levels of accuracy and precision at grade ranges less than 2 ppm gold. At elevated grades, less levels of precision are observed. It should be noted that the presence of 7 outliers (7/193, or 4 percent of total population) does influence the correlation coefficient. On the whole, results from the submission of standard reference material suggest assaying accuracy to be within acceptable limits. The control plots show that 95 percent, 100 percent, 98 percent, 100 percent, 97 percent, 92 percent and 100 percent of samples returned values within an acceptable tolerance of plus or minus 10 percent for CRM’s 300-7,303-2,398-6,900-6, 904-8, GLG304-1 and 307-2 respectively. Although the majority of returned values fall within acceptable limits, CRM 303-2 and 304-1 show a slight bias towards over-reporting grades, whilst CRM 398-6 and 300-7 show a slight bias towards under reporting grades. There appear to be no significant, non-random patterns to any dataset other than weak to moderate cyclicity within acceptable limits. It is probable that this cyclicity is related to equipment calibration. Outliers are present in the control charts, notably for CRM G300-7, GLG 304-1, G398-6 and G904-8. Review of these outliers indicates that they may be due to incorrect labeling of the CRM and Blank samples, resulting in some confusion in values. CSA recommends that Lydian reviews systems currently in place that manage the insertion of CRM samples to minimize these errors in future. The results of standard analysis suggest no significant bias exists and assay results may be considered accurate. CSA notes that although flagged, outliers have not been investigated by Lydian at the time of reporting. CSA recommends that QA/QC data should be monitored as drilling progresses, and any erroneous data investigated as they arise. Lydian plans to improve QA/QC monitoring during the next phase of drilling, which should address this. CSA considers the assay results collected from RC drilling and diamond drilling to be reliable for the purposes of resource estimation, being representative of the sampled material and exhibiting no significant bias. RC and diamond assay datasets exhibit similar population distributions and are considered compatible for use in resource estimation. Current blank samples are sourced from local basalt for Diamond samples. Although no significant contamination has been identified CSA would recommend that

Lydian source certified blank material to align their procedures with industry best practice. 12.6 Laboratory QA/QC Lydian provided results of Laboratory QA/QC duplicate analysis to CSA for review. Results from the analysis of Laboratory duplicate sample assays suggest a reasonable correlation between the original assay and the duplicate assay for both RC and Diamond drilling, with correlation coefficients of 0.99 for both, Figure 12.20 and 12.21. These figures show that duplicate results exhibit acceptable levels of accuracy and precision at grade ranges less than 2 ppm gold. At elevated grades, less levels of precision are observed.

CSA considers the results of Lydian’s internal QA/QC and the results detailed above adequate to assess the accuracy and precision of the ALS Chemex analytical laboratory in Romania. CSA would recommend that Lydian undertake a lab audit at the facility to review procedures and ensure that Lydian samples are being prepared and analyzed to industry best practice. 12.7 Geophysical Surveying Geophysical surveying was undertaken across the Amulsar prospect by Newmont during the now finished Joint Venture agreement with Lydian. Geophysical surveying during 2007/2008 was supervised by Mark Goldie, a Newmont geophysicist. Mr Goldie was also bought in during the interpretation and modeling work as a consultant for Condor Consulting during 2010. Approximately 150 line km of ground magnetic data was collected on a series of east west lines in 2006/2007 and 2009. Line spacing in 2006/2007 was 100 m increasing to 200 m during the 2009 survey. A total of 54.6 line km of induced polarization (IP) and resistivity (100m dipole-dipole) was completed over the Amulsar area during 2007 and 2008, Figure 12.22.

Figure 12.22 - Amulsar location map detailing magnetic and resistivity surveys

CSA reviewed two reports written by Mark Goldie, “Report on IP/Resistivity Surveys performed at the Amulsar Project, Armenia 2007 & 2008” and “Lydian Head Office Trip Summary: November 15 to 19, 2010”, contained in Appendix E of the May 19, 2011 43-101 Technical Report mention in the Introduction. These reports include the following conclusions; IP/Resistivity values, principally derived from the 2007 survey over the main area of interest, of several thousand to tens of thousands of ohm-m correspond well with the zones of known silicification, while the corresponding low chargeability reflects the depth of oxidation. Conversely, the 2008 survey area generally exhibits low resistivity, and high chargeability values in the order of 30 to 40 msec. This could represent an area of argillic alteration that contains 5 to 10 percent disseminated sulphides and may be related to a distal porphyry style system (Goldie 2008). The response of the magnetic data at Amulsar is clearly illustrating the contrast between the areas of known alteration (absence of magnetism) with the surrounding unaltered volcanics. Some lineaments can be seen in the derivative products that may represent structure (Goldie, 2010). The following recommendations were made as part of the 2010 report:

▪ Selected core and surface rock samples be collected and sent to a laboratory for physical property measurements. Susceptibility, IP, resistivity, and density information derived from this exercise will help the interpretation of the geophysical data sets and may help plan any future surveys. It is suggested

Page 94: LYDIAN INTERNATIONAL, LTD. · 2015. 6. 15. · 1. I am an Independent Mineral Process Engineering Consultant and contributed to a Report entitled “Lydian International, Ltd., Development

that a series of samples from each member of a suite of rock and alteration types be considered.

▪ Airborne magnetic/EM survey be considered to cover the Amulsar license. It

is recommended that a VTEM platform be used to fly approximately 1500 line km in an east-west direction with 100 m line spacing. The results of this survey could help in the prioritization of additional targets outside of the known area on known mineralization. The resistivity information could help identify silicification related to high sulphidation mineralization under the basalt cover, while the magnetics and resistivity could help identify other possible targets such as porphyries or base metals.

▪ Follow-up of any interesting anomalies based on the airborne survey should

be field checked and sampled with possible consideration for additional IP/resistivity to assist in the targeting. A conventional IP/resistivity approach will probably be sufficient to follow-up, but if there is a need to improve the resolution and depth of investigation of the original data sets, a Titan24 IP/resistivity approach should be considered

If there is interest in learning more about the underlying sediments and their possible relation to the mineralization at Amulsar, a ground gravity orientation reconnaissance survey could be considered at Amulsar. It is assumed that there will be a density contrast between the volcanics and sediments and that this boundary can be mapped with the gravity. Ideally the survey should extend out to any known outcropping sediments and some samples from this rock type should be sent out for physical property measurements. As a first pass, 300 to 400 stations could be collected along areas of vehicle access within the Amulsar license, such as roads and tracks, at approximately 500 m spacing. There are a number of geophysical contractors that could run this survey, and perhaps there is some capability within Armenia (i.e. through the government survey).

▪ An effort should be made to track down the raw IP/resistivity data files from Newmont (instrument dump files). These files contain important information related to the quality of the field measurements that may be of future use to Lydian.

▪ Although low priority, it may be worthwhile at some time to re-model the

IP/resistivity data in 2D with the recently acquired detailed topographic data. During 2010 Lydian staff and Mark Goldie created 3D geophysical models, generating point data with corresponding X, Y, Z locations. Lydian staff then used these 3D models to generate the following plots using a simple nearest neighbor estimation of values in Datamine, Figures 12.23 to 12.25.

Figure 12.25 - 3D Chargeability Data sliced by Rl

Lydian interprets the strong resistivity anomalies as being due to the silica alteration. There is a close relationship between the existing drilling and the resistivity anomalies which conforms this correlation. At deeper RL’s the resistivity identifies strong anomalies at Erato, to the north and east of Tigranes and to the south of Artavasdes. These areas have largely been untested by drilling and may also represent areas of silicification. The chargeability plots show small scattered highs at the higher RL levels which are interpreted as being associated with the pyrite rich porphyry andesite. At deeper RL levels a pronounced chargeability high occurs to the south and south west of Artavasdes. Lydian has embarked on an exploration drilling programme in this area which should identify the source of this chargeability anomaly. It is apparent that the bulk of the existing drilling is in areas of low chargeability and these areas are interpreted to represent oxidized silicified volcanics.

The 3D magnetics are dominated by gravity lows with small magnetic highs in the Tigranes, Artavasdes and Erato areas associated with areas of know mineralization. Sharp changes between magnetic highs and lows may represent fault structures. The 3D geophysics has been incorporated into Lydian’s drill planning for 2011.

13.0 MINERAL PROCESSING AND METALLURGICAL TESTING The following is a discussion of the metallurgical testing aspects of the proposed Amulsar Project. 13.1 SGS Lakefield Research (2008) In September 2008 a gold recovery test program was undertaken at SGS Lakefield in Canada on a crushed continuous half drill-core from the entire 146 m length of hole DDA-004, a scout hole from the 2007 drill program. The metallurgical program consisted of a qualitative mineralogical evaluation of the composited sample, Bond ball mill work index determination, gravity concentration, cyanide leaching of the gravity tailings and the whole ore, and an evaluation of the amenability or the ore to heap leaching. A summary of this work is contained in the March 2009 report, to which the reader is referred. 13.1.1 Head Assays Two 1-kg charges were submitted for duplicate screened metallics analysis for gold at 150 mesh. The minus 150 mesh fraction was assayed for gold in duplicate. The results indicated that the calculated head grade for the samples submitted for assay was 1.06 to 1.08 g/t gold. Only 1.5 to 1.9 percent of the gold reported into the plus 150 mesh fraction, indicating the gravity recoverable gold component in this sample is fairly low. A 100 to 200 gram sample of the minus 10 mesh material was submitted for S, S2- and a multi-element semi-quantitative ICP scan. The results of these assays are summarized below in Tables 13.1 and 13.2.

13.1.2 Mineralogy A 1-kg sample of Composite 1 was submitted for qualitative mineralogical evaluation. The standard “rapid mineral scan” examination was applied, which includes general mineral assemblage with manual grain counting. An X-ray diffraction analysis was included for the identification of the major minerals. The rapid mineral scan evaluates the bulk petrography and general mineral types, abundances and grain size ranges. The rapid mineral scan indicated that the Composite 1 sample consisted of the following crystalline mineral assemblage phases:

▪ Major - quartz ▪ Minor - hematite

- goethite - potassium-feldspar - rutile

▪ Trace - chlorite - mica - alunite

13.1.3 Coarse Bottle Roll Leach Test Results In order to evaluate the amenability of the ore to heap leaching, a series of coarse ore bottle roll tests was completed at two feed sizes, minus 1/2 inch and minus 1/4 inch. Typically, in these tests the bottles are rolled intermittently (1 minute every

13.1.4 Testwork Summary In addition to the coarse bottle roll leach tests, Composite 1 was also subjected to gravity separation test work and bottle roll tests on ground samples. A summary of all the test results is shown in Table 13.4.

▪ For all tests a gold recovery of 90 percent was established after only 8 hours, and reached 95 percent after 24 hours, both with modest to moderate NaCN consumptions.

▪ The results suggested that the mineralization is amenable to heap leaching

and conventional whole ore cyanidation. Given the minor difference in the gold leach recoveries obtained for the two process routes, heap leaching would be the preferred process option.

▪ The recovery of gold was in the range of 96 to 97 percent, leaving a residue

assay of 0.03 to 0.06 g/t gold.

▪ The reagent consumptions were very low, below 0.1 kg/t NaCN and 0.3 kg/t lime.

13.2 SGS Mineral Services UK Ltd During 2009 Lydian engaged SGS Mineral Services UK Ltd to conduct further testwork, focusing on coarser fractions and lower cyanide concentration solution concentrations than previous testwork and included column leach tests on large fraction half-core.

The test work was conducted on three master composites (labeled A, B and C) of half drill core samples from different parts of the Tigranes and Artavasdes areas. The composites were differentiated by alteration style and by gold and multi-element distribution. The three composites had head grades ranging from 1.09 to 1.29 g/t gold.

Metallic screen analyses of the composites show that greater than 98 percent of

the gold reported to the minus 106 micron fraction. The results confirm the observations made in previous work indicating that a gravity concentration step is not warranted with the absence of a significant coarse gold component.

Cyanidation bottle roll leach tests were conducted at two size distributions, minus

75 microns and minus 2 mm.

13.2.1 Bottle Roll Leach Tests

Cyanidation bottle roll leach tests were conducted at two size distributions, minus 75 microns and minus 2 mm, to approximate conventional CIL and heap leach technologies. The results are shown in Tables 13.5 and 13.6.

For all three composites, higher gold recoveries were attained at a crush size of minus 19 mm than at minus 38 mm. Leach kinetics were also rapid with 80 percent of the gold leached after 20 days at the minus 19 mm crush size.

A review of all final gold recovery results for all tests showed that Composite A

produced the highest level of gold recovery in all but the minus 38 mm column leach test. These results are summarized in Table 13.9.

These initial scoping testwork results suggest attractive processing economics of

the Amulsar project. Bulk mining of low-grade ore with a leach operation requiring three stages of crushing is feasible.

13.3 Wardell Armstrong International (2010) In 2010, Lydian commissioned WAI to undertake a further program of laboratory testing on the Composite A and Composite B samples originally tested by SGS. The testwork generally focused on leaching at finer crush sizes and using higher cyanide concentrations than were used in the SGS testwork. 13.3.1 Column Leach Tests Column testwork was conducted using cyanide concentrations of 0.075, 0.050 and 0.025 percent. The crush sizes were 38, 25, 18 and 12 millimeters. The columns were irrigated at a rate of 10 l/m2/h and the leach period was 68 days. The column leach test results are given in Table 13.10 and the column leach recovery curves in Figure 13.4.

The test results indicate that for both sample the optimum crush size may be 19

mm and the optimum cyanide concentration 0.05 percent, although, further work will be required to substantiate this. Tests using the higher cyanide concentrations also gave higher cyanide consumptions and the additional gold recovery needs to be related to the additional cyanide costs. The same is true for the additional costs of crushing to the finer sizes. 13.4 Wardell Armstrong International (2011) In late 2010 Lydian shipped full core from three diamond drill holes carried out in each of the deposits, Tigranes, Artavasdes and Erato, to WAI for coarse bottle roll and column leach testwork. 13.4.1 Coarse Bottle Roll Leach Tests

To determine variability in gold recovery arising from rock type and crush size coarse bottle roll leach tests were conducted on individual drill hole intervals at crush sizes of minus 12 mm and 19 mm.

The tests indicate that there is minimal metallurgical variability with respect to gold recovery as a function of rock and deposit type.

Figure 13.6 plots the gold leach recoveries as a function of head grade. It is evident that there is no effect of head grade on gold leach recovery. The two low leach recovery points, less than 82.5 percent, were for samples from the Artavasdes deposit. One of the samples had a high gold grade of 14 g/t and thus potentially could have had insufficient leach residence time, whilst the second sample had a low head grade of 0.30 g/t.

Future work will address silver extraction parameters. 13.4.2 Current Testing - Column Leach Tests At the time of writing this report drill hole intervals for each column leach test had been selected to prepare columns for each of the rock types:

▪ Leached and Iron Oxide Rich Gossan, Silicified ▪ Medium Iron Oxide, Siliceous ▪ Fault Gouge Zone ▪ Siliceous Breccia

Plus three columns to represent a master composite for each of the drill holes for:

▪ Tigranes ▪ Artavasdes ▪ Erato

Based on the coarse bottle roll leach tests the optimal crush size for the column leach tests to be carried out will be 100 percent -12 mm.

Particle size determinations conducted on each of the composite samples indicated that the percentage of minus 38 µm material was on average 5 percent by weight. Hence it was decided not to conduct any percolation/agglomeration tests ahead of the column leach tests. Percolation tests will be conducted once the columns have been terminated. 13.5 Future Testwork

As part of the 2011 field season there are plans to drill specific metallurgical diamond drill PQ holes. The purpose of these diamond drill holes will be to prepare composite samples that represent both depth and spatial across the Tigranes and Artavasdes open pit shells. Particular focuses will also emphasize on drilling within the starter pit to prepare metallurgical samples for column leach testing during the payback period i.e. first three years.

13.6 Heap Leach Design

The test results confirmed that the Amulsar gold mineralization is amenable to

recovery using heap leach technology. Conventional three-stage crushing, followed by stacking, leaching and gold recovery will be required. The design parameters for the leach stage are summarized in Table 13.13.

Table 13.13

Heap Leach Design Parameters Parameter Units Design Lift Height m 8 Solution Application Rate l/m2/h 8-10 Primary Leach Cycle days 30 Secondary Leach Cycle days 80 Solution:Ore Application kl/t 3.0

The design solution:ore application ratio of 3.0 kl/t was derived to attain an

overall gold leach recovery of 90 percent, as shown in Figure 13.7. The solution:ore application rate was derived from a column leach test conducted at a crush size of minus 12 mm and feed solution cyanide concentration of 0.5 g/l. These are the same parameters used for the current column leach tests being carried out by WAI.

In order to achieve a solution:ore application rate of 3.0 kl/t, a total leach cycle

time of 140 days is required at 10 l/m2/h. The design total leach cycle for a single lift is 110 days therefore the remaining gold will be leached in subsequent lifts. The primary leach cycle is designed to recover circa 70 percent of the gold, whilst an additional 10 percent will be recovered in the secondary leach cycle. The remaining 5 percent gold recovery will be leached in subsequent multiple lift leaching.

Laboratory column leach test recovery is downgraded by 5 percent to reflect the attainable full scale heap leach recovery due to losses on the side of the heap and due to channeling effects.

The main reason for limiting the leach cycle is to ensure that the pregnant leach

solution (PLS) grade to the adsorption circuit is maintained as high as possible. The current design PLS grade is circa 0.52 ppm gold. During the operations stage the operations staff will make the call when to terminate the leach cycle on each of the cells.

Figure 13.7 - Solution Application Rate vs. Leach Recovery

13.7 Metallurgical Recovery & Reagent Consumption Predictions

Initial column leaching was exceptionally rapid for both samples with up to 70 to

75 percent gold recovered after seven days of leaching; at crush size minus 12 mm. Initial column leach testing would indicate that circa 90 percent gold leach recovery is attainable after 140 days of leaching. For the PEA an overall gold recovery of 85 percent is used.

Column leach test recoveries are typically downgraded 2 to 5 percent units in the

full scale heap leach to take into account gold losses on the side of the heaps and due to inefficiencies arising in solution percolation within the heap.

Initial indications of cyanide and lime consumptions are that they will be low. Cyanide consumption is in the range 0.2 to 0.4 kg/t, whilst lime consumption is around 1 to 1.2 kg/t. Reagent consumptions in the laboratory are much higher than those obtained in the full scale heap, due to the recycling of leach liquor in a heap, as opposed to a static column which is in open cycle. The full scale plant reagent consumptions are typically half of those recorded in the laboratory.

These initial scoping testwork results suggest attractive processing economics of

the Amulsar project. Bulk mining of low-grade ore with a leach operation requiring three stage crushing is feasible.

14.0 MINERAL RESOURCE ESTIMATES

The text in Section 14.0 is a summary from the CSA Mineral Resource Estimate Report R210, dated 18 May 2011. Reference should be made to that report for the full details of the project geology and resource estimates.

During 2010 Lydian staff undertook a thorough review of the Amulsar geology,

including surface mapping, logging of oriented drill core and closer spaced infill drilling. This has resulted in the generation of a more robust geological model, where lower grade strata-bound mineralisation and higher grade structural bound mineralisation are defined.

The work program at Amulsar has been designed to define the scale of the

epithermal system and the extent and grade of the gold mineralization within that system. Drilling in 2008 was focussed on defining the main body of the Amulsar deposit to satisfy regulatory requirements to gain a mining license. Drilling in 2009 was undertaken as a step out program, surrounding the previous drilling and to test the extents of the Amulsar deposit. Drilling in 2010 was focussed on infill drilling at Artavasdes, Tigranes and Erato, to upgrade some parts of the resource to higher categories.

Work completed by Lydian since the production of the Mineral Resource

Estimate (MRE) in December 2009 comprised RC drilling, diamond drilling, trenching, channel sampling and sample assaying.

The mineral resource estimate comprised two sets of domain wireframes, the

first based on 0.2 to 0.3 sub-horizontal strata-bound materials the second based on 0.3 g/t Au and greater focused on mineralization that was structurally controlled. Domain wireframes were created by Lydian with input from CSA. The structural domains were then grouped according to their dominant strike orientation. A total of 12 domains were identified and used during mineral resource estimation.

The generation of distinct strata-bound and structural domains has greatly

reduced grade mixing that was highlighted as an issue during the previous resource estimates. Further refinement of these wireframes should reduce the minimal amount of grade mixing that is observed in the current domains.

Gold grade was estimated into a Block model with cells 20m x 20m x 5 m (X x Y

x Z), sub celled down to 2m x 2m x 0.5m (X x Y x Z). Bulk density was assigned according to dominant rock type.

The Amulsar Mineral Resource Estimate (MRE), dated 4 August 2011, has been

classified in accordance with CIM guidelines using the following criteria;

▪ Interpolation criteria based on sample density, variography, search and interpolation parameters.

▪ Assessment of the reliability and confidence that can be given to geological, sample, survey and bulk density data used in modelling. CSA have classified the Amulsar Mineral Resource Estimate as both Indicated

and Inferred Resources. As of 18 May 2011 the CIM compliant Indicated and Inferred Mineral Resource,

reported at a 0.4 g/t cut-off totalling 80.7 Mt @ 0.97 g/t gold for 2.52 million ounces, of this total 32.4 Mt @ 1.1 g/t gold for 1.1 million ounces is contained within the Indicated Resource and 48.3 Mt @ 0.9 g/t gold for 1.4 million ounces is contained within the Inferred Resource was delineated.

15.0 MINERAL RESERVE ESTIMATES

The mine PMM estimates, pit optimization study and mining costs have been investigated by CSA Global (UK) and are described in detail in the CSA report number R268.2011 prepared for Lydian in July 2011. The following is a summary from this report.

In April 2011, Lydian International Pty (“Lydian”) commissioned CSA Global (UK)

Ltd (“CSA”) to undertake the mining portion of a Preliminary Economic Assessment (PEA) review of the available information relating to the Amulsar Gold Project, located in Armenia, with the objective of developing a concept for the successful development of the project.

The initial stage of this work was to carry out pit optimisation work based on

physical and financial parameters agreed between CSA and Lydian. CSA has not carried out independent review of these parameters at this initial stage of the study and has relied on the information provided by Lydian.

CSA completed most of this preliminary optimisation work during April and May

2011. The purpose of this work was to test a series of options involving combinations of Inferred and Indicated resources and pit wall slopes. All other physical and economic parameters for each scenario remained unchanged. In particular, the initial optimisation work was carried out to test whether the resources which are currently in the Inferred Category would be economically mineable if further drilling were to be carried out to bring them to the Indicated Category.

The outcomes of the optimisation runs have been combined during June/July 2011

into an economic analysis to provide a preliminary indication of the viability of the project and generate sensitivity studies to changes in key economic and operational parameters particularly the option of a contractor mining verses owner mining operation. Study Approach

The following work was undertaken:

▪ Preliminary estimation of operating costs for Amulsar gold deposit

▪ Pit optimizations to determine practical pit limits, whilst maximizing the project value, using Whittle Four-X software

▪ Sensitivity analysis to determine the influence of changes in various factors on

the project ▪ Pit designs on selected optimisation shells ▪ Reporting of inventories within the Amulsar pit designs ▪ Determination of waste dump volume requirements and waste dump designs

The gold resource used in the Whittle optimiser is detailed in Table 15.1. It

should be noted that a lower cut-off grade of 0.2 g/t compared to the computed resources at a cut-off grade of 0.4 g/t was used.

Whittle Optimization Results

A balance of DCF and maximum PMM tonnes was used to select the preferred pit shells. Options 3 and 4 were immediately excluded, as a decision was made by Lydian to use the flatter pit slope angles due to a lack of geotechnical data. The optimal pit shell #36 was selected from the Option 1 optimisation. Cut back positions have been selected at Pits #7 and #11. The optimal pit shell #36 was also selected from the Option 2 optimisation. Cut back positions have been selected at Pits #8 and #23.

The decision was made to produce a pit design for Amulsar on the chosen optimal

pit shell using pit shell #36 based on the Option 2 Whittle optimisation.

A further sensitivity analysis examined the effect of adding the inferred material in Erato area to the Option 2 resource to illustrate the potential upside that the addition of this portion of the resource would have on this project should future exploration convert these resources to the measured or indicated category.

The studies indicated that the project is fairly insensitive to fluctuations in process

recoveries of the strata bound mineralization. However, it is sensitive to fluctuations in gold price, mining recovery and process recoveries of the structurally controlled mineralization.

Figure 15.3 and Figure 15.4 illustrate the results of the sensitivity analysis. Note that all sensitivities are based on the undiscounted cash flow.

16.0 MINING METHODS

The following is a summary from CSA Report No R268.2011 submitted to Lydian in July 2011.

16.1 Pit Design Parameters

In designing the final pit for Amulsar, the following criteria have been taken into

account.

• Statutory and safety measures • Policy decisions • Equipment dimensions

Design ore production rates for Amulsar start at 3.75 Mtpa in year 1 ramping up to

10 Mtpa in year 4. From the optimisation studies, the following pit shells have been chosen on which

to base the pit designs. A pit design was only completed on the final pit shell.

Features of the pit design include:

▪ 25m wide ramps to allow for the safe passing of the selected haulage trucks with an allowance for a bund wall on the open side of the ramp.

▪ A ramp gradient which allows the selected haulage trucks to maintain maximum

production.

▪ A minimum pit base width of 20m to allow for load and haul operations.

Figure 16.1 - Pit Design Terminology

16.1.1 Pit Designs

Figure 16.2 and Figure 16.3 below are plan and oblique views of the pit design of Amulsar based on the Amulsar Indicated and Inferred optimisation. The ramp daylights on the north eastern edge of the pit, close to the areas allocated for waste dumping. The final pit utilises a clockwise spiral ramp from the pit exit to access 2,688 mRL in the southern end of the pit with a switchback at 2,758 mRL to access 2,728 mRL in the northern end of the pit.

Due to the mountainous topography, the area of the waste dump is expansive

and straddles multiple valleys extending some distance from the pit, thus increasing haul distances. The open pit is also expansive with a North-South length of some 1.3 km which also contributes to increased haulage distances.

Table 16.3 below summarise the total rock tonnes, insitu and diluted ore tonnes

and grades, waste tonnes and insitu and diluted gold content within each of the mining areas of the Amulsar pit design reported by 10 metre bench.

16.2 Waste Dump Location and Design

The waste dump for Amulsar is located to the east and northeast of the main pit, in the least visible location from the majority of the communities. The average from the pit was assumed to be 1 km. The viability of in-pit dumping will be investigated as part of the BFS to potentially reduce the footprint of the surface dump, if possible.

Due to the mountainous topography, the area of the waste dump is expansive

and straddles multiple valleys extending some distance from the pit, thus increasing haul distances. This area has been nominated by Lydian as the area least likely to be mineralised in the vicinity of the pit.

If necessary, mine waste will be segregated and/or appropriately managed to

mitigate any potential Acid Rock Drainage (ARD) in accordance with the results of the ESIA ARD assessment programme. The design of the waste dump will incorporate appropriate drainage and environmental protection measures, as necessary.

Based on a swell factor of 35%, the total volume required for waste dumping for

Amulsar is 78.6 Mlcm. The swell factor has been assumed by CSA for this study and requires confirmation by future testwork. Table 16.4 provides a breakdown of the waste dump volume requirement.

16.3 Mining Methodology 16.3.1 Introduction

This study investigates two mining options at Amulsar, an owner operator mining operation and a contractor mining operation. All mining costs have been derived from typical mining costs for an operation of similar type and size.

The mining operation has been based on the following assumptions; ▪ Surface mining only

▪ Drilling and blasting of waste on 10 m benches

▪ Bulk mining of ore from the high grade structurally controlled and low grade

strata-bound ore resources

▪ A relatively small pool of local skilled and semi-skilled labour

▪ A large fleet of 130 t and 90 t rear dump mechanical drive haul trucks selected since they are in current use or on order by mining companies in Armenia and are supported by local dealers

16.3.2 Mining

The mining method assumed for the Amulsar deposit considered in this study will be conventional open pit mining, with drilling and blasting of waste on 10m benches and drilling and blasting of ore on 5m or 10m benches, depending on the ore demarcation required for grade control purposes. Load and haul will be done on flitches varying between 5m and 10m in height. The general process of loading ore and waste will use backhoe or shovel type excavators with the excavator sitting on the production bench while the haulage trucks are loaded on the level below.

The mining sequence will include removal of waste to dumps and the mining of

ore and its delivery either to the specified ROM pads or direct tipping into the conveyor bin in close proximity to the open pit. Ore from the ROM will then be transported from the pit to the Heap Leach (HL) plant by conveyor.

Ore extraction will be by a bulk mining method. The cost estimates include an allowance for grade control as there will be a requirement to mine ore and waste with a minimum of dilution and maximise recovery.

Standard ancillary equipment will be used where necessary for smooth graded floors and face clean-ups.

16.4 Open Pit Production Equipment 16.4.1 Selection Criteria

Mining operations have been assumed to work two 12 hour shifts per day six days per week. Mining equipment selection is based on optimal utilisation of the selected equipment. 16.4.2 Drilling

Drill rigs such as Sandvik Pantera DP1500 drills capable of drilling holes with diameter between 89 mm and 150 mm and Tamrock Ranger DX 700 drills capable of drilling holes with diameters between 64 mm and 115 mm would be sufficient for this operation. These one man operated diesel hydraulic drills have a stated capacity of up to 15 m per hour in hard strata.

Up to five drill rigs will be required to meet peak production for in pit ore and waste grade control and blast hole drilling at Amulsar, including allowance for downtime. 16.4.3 Loading Equipment

Loading equipment planned for Amulsar consists of 180 t hydraulic shovels such as an RH-90 class primarily for loading of ore and 250 t hydraulic shovels such as an RH-120 class for loading of waste.

Up to three RH-90 and two RH-120 hydraulic shovels will be required to meet peak production for in pit ore and waste loading at Amulsar, including allowance for downtime.

Provision has been made in this study for wheel loaders to load approximately 40 percent of ROM ore onto the conveyor for transportation to the HL plant, with the remainder being direct tipped by haul truck into the conveyor bin. 16.4.4 In Pit Haulage Trucks

A fleet of Cat 777 90-t haul trucks is planned primarily for ore transportation and a fleet of Cat 785 130-t haul trucks is planned primarily for waste transportation. Maximum truck size is constrained by equipment availability in Armenia.

Up to twenty one 777 haul trucks and sixteen 785 haul trucks will be required to meet peak production for in pit ore and waste haulage at Amulsar, including allowance for downtime. Haul distances from pit base to ramp exit and surface haulage to RoM and waste dump will be up to 2 km one way, requiring the large trucking fleets.

16.4.5 Ancillary Equipment

Ancillary equipment will include the following: ▪ Graders ▪ Dozers ▪ Service trucks ▪ Explosives transport ▪ General Purpose trucks ▪ Personnel transport ▪ Light vehicles ▪ ROM loader

16.5 Amulsar Production Schedule

A Life of Mine (LoM) mining schedule has been developed for the Amulsar open pit. The aim of the LoM schedule was to find a balance between mining high grade material as early as possible in order to get maximum returns, whilst minimising the use of stockpiles in order to keep re-handling costs to a minimum. Stockpiles were used in the schedule to smooth out annual PMM and waste mining. Strip ratios increase in later years in the schedule which mean that waste mining has to increase to maintain Heap Leach Feed. To mitigate this effect, stockpiles are created to supplement Heap Leach feed when strip ratios increase.

17.0 RECOVERY METHODS

Development of the Amulsar Project will be conducted in two phases. Phase I is the construction of a facility to process ore at a rate of 5 Mtpa. In the third year of operation Phase II will be constructed to increase throughput to 10 Mtpa for year four. The Phase II expansion will essentially entail installation of a duplicate Phase I facility, though some of the unit operations and ore handling equipment will be initially installed to support the 10 Mtpa processing rate. Attached in Appendix 1 are Design Criteria for Phase I and Phase II. Attached in Appendix 2 are Equipment Lists for Phase I and Phase II.

17.1 Crushing Plant and Stacking Ore is processed through three stages of crushing. 17.1.1 Primary Crushing Run-of-mine ore is delivered to the primary crusher feed hopper, or adjacent stockpile, by rear-dump haul trucks. A static grizzly screen above the hopper limits the top size of rock fed to the crusher to 700 mm. Below the hopper, an apron feed transfers ore at a controlled rate to the vibrating grizzly screen. Grizzly screen oversize, plus 100 mm material, feeds the primary jaw crusher. Grizzly screen undersize joins the crusher product on the primary crusher discharge conveyor which feeds the primary crusher transfer conveyor taking the ore to the second stage of crushing. The primary crushing circuit reduces the size of run-of-mine from a maximum of 700 mm to approximately 80 percent passing 165 mm. The rock breaker is installed to serve the static grizzly and the monorail crane and air compressor support jaw crusher operation. Dust is controlled at the feed pocket by water sprays and at the screens and transfer points by dust collection/filtration in the bag house. Tramp iron is removed from the crushed product by way of the magnet mounted above the discharge of the discharge conveyor. In the Phase II expansion, the entire primary crushing circuit is duplicated except both phases share a common run-of-mine stockpile, dust bag house, air compressor and transfer conveyor. 17.1.2 Secondary Crushing Primary crushed product is fed into the coarse ore storage bin. Two apron feeders transfer the ore to the coarse ore transfer conveyor which feed ore at a controlled rate to the secondary vibrating screen deck. The screen deck oversize, plus 100 mm and plus 28 mm, is fed to the secondary cone crusher. Screen deck undersize joins the secondary crusher product on a transfer conveyor for delivery to the third stage of crushing. Secondary crushing reduces the primary crushed product to approximately 80 percent passing 32 mm. The crane and air compressor is installed to support crushing operations and dust is controlled at the screen deck and crusher by collection/filtration. The Phase II expansion shares the coarse ore storage bin, crane, air compressor and product transfer conveyor with Phase I, but requires installation of two additional apron feeders, one vibrating screen deck and one secondary cone crusher. 17.1.3 Tertiary Crushing Secondary crushed product is discharged onto the fine ore screen tripper conveyor and delivered to the fine ore screen feed bin. The belt feeder delivers ore from the bin to the double deck vibrating screen. Screen oversize, plus 30 mm and plus 17 mm, reports to the screen oversize tripper conveyor and discharged into the tertiary crusher feed bin. Two belt feeders deliver the screen oversize material to two tertiary short cone crushers. The tertiary crushed product is discharged onto the fine ore screen tripper conveyor and recirculates back to the vibrating screen. The screen undersize, approximately 80 percent

passing 12 mm, reports to the fine ore collection conveyor which discharges onto the fine ore transfer conveyor. The fine ore transfer conveyor delivers ore to the crushed ore tripper conveyor and into the crushed ore surge bin. Four belt feeders transfer crushed ore from the surge bin to the overland conveyor. Tertiary crushing is supported by the air compressor and crane hoist. Dust is controlled at all transfer points, the screen and crushers by collection/filtration. The Phase II expansion requires installation of a second tertiary vibrating screen and belt feeder and two additional tertiary cone crushers with belt feeders. 17.1.4 Stacking The overland conveyor brings the ore to the vicinity of the leach pad and runs along the north side of the pad. Pebble lime is added to the ore on the overland conveyor by way of a storage silo and screw feeders with the rate of lime addition varying with tonnage. The ore with lime is discharged onto a network of up to 8 portable conveyors terminating at a radial stacking conveyor. Ore is discharged from the stacking conveyor onto the heap leach pad to an ore height of 8 meters. The overland conveyor, lime silo, portable conveyors and stacking conveyor are all sized and installed in Phase I to accommodate the increase in throughput required in Phase II, although, an additional 16 portable conveyors will ultimately be purchased as the overall height of the pad increases. 17.2 Heap Leach

Golder completed and submitted to Lydian a separate document detailing a conceptual design and cost estimate for the leach pad and ponds. Heap leaching consists of stacking the crushed ore on the leach pad in lifts and leaching each individual lift to extract the gold. Barren leach solution (BLS) containing approximately 1 g/l sodium cyanide is applied to the ore heap surface using drippers at an application rate of 10 l/h/m2. The overall leaching cycle for the ore is at least 140 days total with 30 days of primary leaching, 80 days of secondary leaching and 30 days of leaching as a buried lift. This is equivalent to a solution-to-ore application ratio of 3 m3/t ore. Leaching commences as the BLS piping is installed on the surface of the first heap lift with a sufficient area to accommodate the applied solution flow rate. The solution percolates through the ore to the impermeable pad liner where it collects in a network of perforated drain pipes installed within a 0.6 meter thick granular cover drain fill layer above the liner. The leaching process is carried out as a two-stage counter-current leach in order to maximize the gold tenor to the gold recovery process. Leach solution of intermediate strength is used as recycle leach solution (RLS) to leach freshly stacked ore. This produces a higher gold grade pregnant leach solution (PLS) reporting to the pregnant pond.

17.2.1 Leach Pad

The lined leach pad at Site 13 will be constructed in three phases with the ultimate ore heap amount of 75 Mt stacked in three stages. Each pad phase will be divided into two cells for a total of six cells.

The Phase 1 (Starter) pad will be constructed in the graded valley bottom and rise up the surrounding valley slopes enough height to accommodate the Stage 1 heap of approximately 13.4 Mt, which will be stacked on the Phase 1 pad in six 8 m thick lifts during the first three years of operation. The Phase 1 pad will have an area of 347,430 m2 and the Stage 1 heap will have a top surface elevation of 2,396 m.

The Phase 2 pad will be an expansion to the Phase 1 pad up the valley slopes and will have an area of 431,100 m2. The Phase 2 pad will allow the stacking of the Stage 2 heap of approximately 28.9 Mt in four additional lifts above the Stage 1 heap for an approximate cumulative heap amount of 42.3 Mt with a heap top surface elevation of 2,428 m. Stacking of the Stage 2 heap will continue through Year 6 of Operation.

The Phase 3 pad will again be an expansion to the Phase 2 pad up the valley slopes to the Ultimate pad limits. The Phase 3 pad will have an area of 265,630 m2, and the Ultimate (Phases 1, 2 and 3) pad area will be 1,044,160 m2. The Phase 3 pad will allow the stacking of the Stage 3 heap of approximately 32.7 Mt in six additional lifts above the Stage 2 heap for an Ultimate heap amount of 75.0 Mt with a heap top surface elevation of 2,476 m. Stacking of the Stage 3 heap will continue through Year 9 of Operation.

If additional leachable ore resources are identified, the ore may be stacked higher

on Site 13 and/or on a leach pad constructed in the western portion of Site 11 and solution from this pad would be piped to the Site 13 collection ponds.

The pad will have a composite liner system consisting of 2.0 mm LLDPE geomembrane underlain by 0.3-m minimum compacted thickness of low-permeability cohesive soil layer. The geomembrane will be smooth in most areas and may be double-side textured in a strip along the downgradient toe of the pad to enhance heap stability. An interlift liner of similar design may be constructed beneath the Stage 3 heap if deemed necessary due to insufficient percolation of the 80 m high leached ore of Stages 1 and 2 heap, to be determined in the BFS.

The drain pipe network above the pad liner will be embedded within a 0.6-m minimum loose lift thickness liner cover drain fill composed of free-draining, hard, and durable granular material. Solution and storm runoff flows collected by the drain pipe network in each pad cell will be routed via header pipes through the pad spillways to the process ponds, and will be directed by valve control to either the pregnant or intermediate ponds.

17.2.2 Collection Ponds

The collection ponds will consist of process (pregnant and intermediate) ponds, a storm pond, and an underdrain collection and monitoring pond. The collection ponds will be constructed during the Phase 1 pad construction east of the pad downgradient toe in the lowest portion of the Site 13 valley. The ponds will have a crest elevation approximately 8 m higher than the lowest existing ground surface to match the elevation of the pad spillways to the process ponds and minimize site grading cuts. The ponds layout generally matches the terrain in the area to minimize overall site grading.

Solution and storm runoff flows from the leach pad cells will be routed to either the pregnant or the intermediate ponds. A common divider berm will be constructed between the pregnant and intermediate ponds for solution and storm runoff overflow from the pregnant pond to the intermediate pond. A spillway will be constructed between the intermediate pond and the storm pond for storm runoff overflow from the intermediate pond to the storm pond.

The process ponds will accommodate the solution operational and draindown

storage requirements for the Ultimate pad, and the storm pond will accommodate the design storm runoff from the Ultimate pad and pond areas. The required size of the process ponds will double after the first three years of operation as the solution flow rate to the pad is doubled in Year 4 with the doubling of the ore processing tonnage.

The underdrain collection and monitoring pond will collect flows from the underdrains constructed beneath the leach pad and the process and storm ponds. Collected flows meeting acceptable water quality requirements will be discharged into the natural drainage. Collected flows not meeting the requirements will be pumped to the pregnant pond and/or the process plant circuit. The underdrain collection pond will be sized in the BFS to store the anticipated flows with an appropriate safety factor. The pond size shown on Drawing 2 is based on experience and should suffice for the PEA Conceptual Design purposes.

The process ponds and the underdrain collection pond will have a composite liner with a double geomembrane underlain by 0.3-m minimum compacted thickness of low-permeability cohesive soil layer, and a leak detection system between the geomembranes. The bottom (secondary) geomembrane will be 2.0 mm smooth LLDPE and the top (primary) geomembrane will be 2.0 mm single-side textured HDPE with texturing at top for traction. The leak detection system between the geomembranes will consist of a geocomposite connected to a leak detection sump and well system. The storm pond will have a composite liner consisting of 2.0 mm single-side textured HDPE with texturing at top for traction, underlain by 0.3-m minimum compacted thickness of low-permeability cohesive soil layer. 17.3 Process Plant The process plant consists of an ADR Plant, electrowinning cells, a refinery and reagent handling equipment. For the Phase II expansion, essentially a duplicate ADR

plant and electrowinning cells will be installed; the refinery and reagent handling facilities will be initially sized to accommodate the increase in metal production. The entire process plant designed by Scotia International of Nevada, Inc. treats four tonne batches of pregnant 6 x 16 mesh carbon. The plant processing steps include carbon adsorption, carbon acid wash, carbon stripping, carbon regeneration, carbon handling, sodium cyanide and sodium hydroxide mix/storage, electrowinning, and refining.

The sourcing, transportation, handling, use and disposal of any hazardous substances will be regulated in accordance with relevant framework management plans prepared in accordance with international best practice to support the ESIA submission. Brief descriptions of each processing step are presented below. 17.3.1 Carbon Adsorption Pregnant leach solution is pumped into the ADR plant, passes over a trash screen, and enters the bottom of the first carbon adsorption column. The solution flows up through the bed of carbon, over the column top and down into the bottom of the second carbon adsorption column. This is repeated for a total of five carbon adsorption stages and the design is such that solution flows by gravity through the columns. Upon exiting the fifth stage of adsorption the solution, now barren, flows through a carbon safety screen and into the barren solution surge tank. Barren solution is pumped back to irrigate the heap leach pad. The carbon flows through the five stages of adsorption counter-current to the solution. Periodically, once or twice per day, carbon is pumped from the first carbon adsorption column to the acid wash vessel, or alternatively, the strip vessel. Carbon from the second carbon adsorption column is pumped into the first column, the third into the second, and so on. Fresh or regenerated column is added to the fifth carbon adsorption column. Wire samplers are installed on the pregnant and barren leach solution lines. The adsorption plant contains a safety shower and a sump with pump to return solution to the fifth carbon adsorption column. For the Phase II expansion, a duplicate set of carbon columns is installed with associated screens, pumps, and samplers though shares the Phase I sump, shower and barren solution surge tank. 17.3.2 Carbon Acid Wash Loaded carbon is preferably pumped to the acid wash vessel prior to stripping. The acid wash vessel, constructed of fiberglass reinforced plastic, holds four tonnes of carbon. Hydrochloric acid, diluted to approximately 3 to 5 percent, recirculates through the carbon bed for a period of one to two hours. Caustic solution is pumped into the vessel to neutralize the acid followed by fresh water. The caustic solution and wash water report to the neutralization tank which is pumped to the barren solution tank via the carbon safety screen. The washed carbon is pumped to the desorption circuit. The acid

Page 142: LYDIAN INTERNATIONAL, LTD. · 2015. 6. 15. · 1. I am an Independent Mineral Process Engineering Consultant and contributed to a Report entitled “Lydian International, Ltd., Development

Lydian International - Amulsar Heap Leach Facility Preliminary Economic Assessment Page 121

wash circuit is supported by the safety shower, the sump with pump to return solution to the neutralization tank and the exhaust fan to vent acid fumes to the atmosphere. The Phase II expansion does not require modification to the acid wash circuit. 17.3.3 Carbon Stripping Metal is desorbed from the carbon in the strip vessel. The strip vessel holds four tonnes of carbon and operates under conditions of elevated temperature and pressure. Barren strip solution flows up through the bed of carbon, strips gold from the carbon, and then flows through a carbon bucket trap, a plate and frame heat exchanger to exchange heat with the barren strip solution, another trim heat exchanger to further cool the solution before reporting to the electrowinning cell feed tank. Following electrowinning the discharge solution reports to the barren strip solution tank. Caustic and sodium cyanide are added to the barren solution, which is pumped through the plate and frame heat exchanger, past an electric immersion heater, and back into the bottom of the strip vessel. Once or twice per day, the stripped carbon is transferred preferably to the kiln dewatering screen for thermal regeneration, or alternatively, to the carbon sizing screen to be returned to the adsorption circuit. The stripping circuit is supported by the safety shower, wire samplers on the barren and electrowinning feed solutions and the sump with pump to discharge solution to the adsorption circuit trash screen. In the Phase II expansion, an additional strip vessel with all auxiliary equipment is installed except for the sump and safety shower. 17.3.4 Carbon Regeneration Stripped carbon is pumped to the kiln dewatering screen. Transfer solution and fine carbon flow to the carbon fines tank. Carbon sized above 16 mesh reports to the kiln feed bin. By way of the screw feeder, the carbon is passed into the rotating carbon reactivation kiln. Under a steam atmosphere and at temperatures between 550 and 650 degrees Celsius, organic fouling is removed from the carbon. Carbon exits the kiln and reports to the carbon quench tank. The reactivated carbon is pumped to the carbon sizing screen. Transfer water and fine carbon report to the carbon fines tank. The carbon sized above 16 mesh reports to the activated carbon storage tank and, as required, is pumped back into the fifth carbon adsorption column. In the Phase II expansion, an additional kiln, kiln dewatering screen, and quench tank is installed. 17.3.5 Carbon Handling The virgin activated carbon is attritioned prior to being introduced into the adsorption circuit. The carbon is placed into the carbon attrition tank with process solution and mechanically agitated for 20 to 30 minutes. This process breaks off any platelets or sharp corners of the particles, which would have easily broken off while in the adsorption column. Fines generated in this step can amount to 3 to 5 percent of the

initial carbon weight. The attrited carbon is pumped to the carbon sizing screen. Properly sized carbon falls into to the activated carbon storage tank. Fine carbon and transfer solution report to carbon fines tank. The carbon slurry in the fine carbon storage tank is pumped to the filter press. The filtrate flows to the barren solution surge tank. The filter cake is packaged in 50-gallon drums for off-site shipment and treatment. 17.3.6 Electrowinning and Refining The electrowinning feed solution is pumped from the feed tank into the electrowinning cell. Cell electrical power is supplied by the rectifier. Metal is deposited from solution onto stainless steel mesh cathodes. The metal free solution flows to the electrowinning cell discharge surge tank and from there to the barren strip solution tank. Periodically, the sludge is washed from the cell cathodes and is pumped to the plate and frame filter press. The filtrate reports to the barren strip solution tank. The filter cake is placed into the electric retort. Dry cake is blended with flux in the flux mixer and then smelted in the induction bullion furnace. The slag is periodically reprocessed in the furnace though ultimately is packaged into 50-gallon drums for off-site shipment and processing. The doré is packaged for off-site shipment. The refining operations are supported by the exhaust fan over the electrowinning cell, the dust collector over the furnace, the high pressure water sprayer and the sump with pump discharging spill/wash solution to the barren solution strip tank. In the Phase II expansion an additional electrowinning cell and rectifier is installed. 17.3.7 Reagent Handling

In addition to the aforementioned lime silo, facilities are provided to handle the bulk caustic and sodium cyanide. Raw water and sodium hydroxide briquettes are added to the caustic mix tank to a 25 percent concentration. The caustic/mix transfer pump recirculates the solution and then transfers it to the sodium cyanide mix tank. Sodium cyanide is added to the mix tank to obtain a 20 percent concentration. This concentrated solution is transferred to the sodium cyanide storage tank and distributed to the barren solution surge tank and the barren strip solution tank. This reagent handling station is supported by the safety shower and the sump and pump reporting to the barren solution surge tank.

Metering pumps and lines deliver antiscalant directly from 50-gallon drums to the

barren solution surge tank. A pump and line deliver concentrated hydrochloric acid from carboys to the dilute

acid tank.

18.0 INFRASTRUCTURE

This section describes the proposed support facilities for the project. It includes the entire fixed infrastructure for mining operations, as well as the administration and plant operations.

18.1 Existing Infrastructure and Services 18.1.1 Location

The Amulsar Gold Project covers an area of 130 km2, located in south central

Armenia.

18.1.2 Site Access and Roads The Amulsar area is located some 170 km by sealed road from the capital city of

Yerevan, and 15 km by gravel track from the town of Jermuk. The license area straddles the boundary between Vayots-Dzor and Syunik provinces and incorporates part of the main highway south from Yerevan into Iran.

18.1.3 Buildings

An exploration camp owned by Geoteam is established at the site. The camp has

capacity for 15 people in single and shared person accommodation units and the facilities include a kitchen, laundry, office, workshop, warehouses, sewage treatment plant, diesel and fuel tanks / mess building and diesel generator. Geoteam has also established an exploration sample preparation and core/sample storage facility in the village of Gorayk.

There is no allowance for a construction camp. During the construction period the

workers will be housed in Jermuk and travel to and from the work site.

18.1.4 Resources & Infrastructure Infrastructure near the project site is very good. The town of Jermuk is 15 km to the

north and the village of Gorayk some 6 km to the south east of the Amulsar project. Figure 18.1 shows a regional plan giving perspective of where the Amulsar project sits relative to Jermuk and Gorayk as well as the capital city of Yerevan.

There is good infrastructure surrounding the Amulsar project. This includes the

main sealed highway between Yerevan and Iran, high tension power lines and substations, a gas pipeline from Iran, year round water from the Vorotan River and a fibre optic internet cable. As a consequence of the project location on the top of a mountain ridge, a reasonable amount of infrastructure will need to be constructed during project development. In order to ‘fast track’ the project consideration will be given to constructing portable type cabins or skid mounted equipment.

18.1.5 Communications

The exploration camp is currently serviced by satellite disk based internet and TV connection. Mobile phones work on most parts of the project area and a telephone connection is available at the exploration camp.

18.1.6 Personnel

Geoteam has employed a pool of field assistants during the various exploration

programs. It is intended to hire from this pool of known employees as a first priority for the operations phase. Community relations issues are currently handled by HSEC Manager and a Community Liaison Officer and a good understanding of local issues and sensitivities has been established. 18.1.7 Power Supply

The country has ample electric power from nuclear, hydro and heat electro-power

plant sources. Power lines and sub-station infrastructure are located in close proximity to the project area. There is also a hydro-electric power plant on the Vorotan River, which is in the final stages of construction and will have an installed capacity of 1.8 MW. There are plans to increase the capacity to 2 MW. The owners intend to have this in operating in third quarter of 2011.

Power is not currently reticulated to the Project site although domestic usage

power is available at neighbouring main towns to the south and east. The supply of power in Armenia is controlled by the Armenian Electrical Networks company (AEN) that owns the distribution channels of the country in an arrangement whereby in this region power is purchased from the AEN at the 35 kV national grid, stepped down at AEN owned substations and reticulated as required to consumers.

Except for power consumption costs some capital costs to build power lines and

substation must be considered. The high tension power lines that stand along the main highway are 110 kV, however half of the year the line operates under 35 kV. The distance of the potential heap leach site is roughly 13 to 14 km from the highway. The design and construction of the lines for up to 12 km is a fixed cost. If the distance is longer than 12 km, every 250 meter will be an additional cost. The design and the construction of the power lines are done solely by AEN.

The construction and the design of the sub-station, which is an obligation to build,

is a licensed activity in Armenia. There are very limited companies that hold the licenses. An option to construct a 35 kV sub-station should be considered (as the 110 kV is

not available all year around). The 35 kV line will then be stepped down to 6 kV for reticulation around the site. From there the power would be distributed to the crushing plant and the ADR building.

Page 146: LYDIAN INTERNATIONAL, LTD. · 2015. 6. 15. · 1. I am an Independent Mineral Process Engineering Consultant and contributed to a Report entitled “Lydian International, Ltd., Development

K D Engineering Document No. Q439-03-028-01 12 August 2011 KDE FORM No. A263a-7/12/99

Another option is to bring the power in at 35 kV to the main sub-station. Then from the sub-station distribute the power to the crushing and ADR plants, which will both have their own dedicated transformers. Here the 6 kV power would be stepped down to 220 V.

Thus the overall site power requirements are one transformer to step down from 35

kV to 6 kV and two transformers to step down from 6 kV to 220 V.

18.2 Site Development The Project will require development at six major locations: ▪ The mining areas. ▪ The mine surface facilities, including the mine administration building, mine

workshops, refuelling area, mine control areas and explosives yard. ▪ The crushing plant area including administration and contract laboratory. ▪ The ADR plant, leach pad and storage ponds. ▪ Accommodations. ▪ Road and site Access.

The ESIA team provides input into the site selection and design decisions for all

major infrastructure to ensure that environmental, and social considerations inform the mine design process.

The following describes the engineering site preparation requirements at each location. The proposed overall general arrangement layout drawing is shown in Figure 18.1.

18.2.1 Mine Area A nominal area of 40,000 m2 has been earmarked for the mine services area and

is based on similar sized mining operations. The infrastructure required for the mining operation will be provided by the successful mine contractor and typically includes the refuelling station, go-line and mine control facilities for the mining fleet and administration buildings. The chosen site is located on reasonably gently sloping ground to the north of the plant site. The site will be cleared, grubbed and capped with laterite to provide pads for the facilities. A spur from the main haul road will provide mine vehicle access.

A normal area of 10,000 m2 has been earmarked for the explosives magazine. The

magazine area will be located away from the plant site and approximately 1 km north of the mine services area, on a spur off the haul road.

No large, heavily loaded structures are proposed in these areas. Based on similar

previous installations, the allowances made for bulk earthworks in the capital estimate are sufficient to accommodate any minor ground improvements which may be required subsequent to any detailed geotechnical investigations. These would be undertaken at the outset of the Project. 18.2.2 Mine Surface Facilities

The mine service area will be supplied with power by an overhead power line from

the plant. The mine administration and warehouse will be connected to the main PABX at the administration building. An optical fibre cable will connect mine service area computers to the main server. Potable water will be supplied from the water treatment facility at the plant.

The mine contractors services area will include the following facilities: ▪ Mine Administration Office. ▪ Ablutions. ▪ Mine Mess. ▪ Heavy vehicle workshop / store and washdown bay. ▪ Light vehicle workshop. ▪ Heavy vehicle fuelling station. ▪ Light vehicle fuel station. ▪ Fuel storage. ▪ Magazine.

18.2.3 Crushing Plant

The ROM pad and crushing plant will be located to the North of the main open pit. Sub-surface conditions will be established by test pit excavation and core drilling

supervised by Golder.

The crushing plant site will be cleared and grubbed to remove organic material, contoured for drainage and then capped with laterite to allow heavy vehicle traffic during construction. There is extensive laterite available in the area. 18.2.4 Leach Pad & Ponds

The Adsorption-Desorption-Regeneration (ADR) treatment plant will be located to

the East of the heap leach process and storm ponds. Site preparation for the Adsorption/Desorption/Regeneration plant and associated

ponds consist of removing of all economic timber products from the basin area, removing of vegetation, clearing and grubbing of the embankment footprints and under-drainage areas.

A description of the design and construction of the leach pad and ponds is

contained in Section 17.

18.2.5 Accommodation The strategy for accommodating all construction personnel, employees and

security personnel during the construction period will be detailed as part of the BFS.

The town Jermuk has numerous run-down apartment buildings and hotels which could be upgrades for use as staff accommodation negating the need to build a permanent accommodation camp at the Amulsar site. 18.2.6 Roads & Site Access

For supplies, material and equipment can be shipped to the ports of Poti or Batumi,

Georgia then trucked through Georgia and Armenia to the Amulsar project site. Airfreight through the Zvartnots International Airport in Yerevan is also possible.

There is a sealed road from Yerevan to the Iranian border passing to the south of

the project area and a sealed spur road to the town on Jermuk. The current project access is gained via a gravel/dirt road from the Jermuk road. A further gravel/dirt road runs along the Vorotan river valley to the town on Gorayk. The sealed roads to the site turn-off are adequate for all Project transport requirements. The existing gravel/dirt site access road to the mine site will need to be widened over its entire length of 20 km as noted below, and maintained for all weather operation, providing the main means of access to the mine site and associated infrastructure The gravel/dirt road from Gorayk can also be used to access the Amulsar site and will also require upgrading.

The roads required for the Project are: ▪ Plant access road. ▪ Village access road. ▪ Leach pad & ponds access roads. ▪ Mine haul roads.

▪ Borefield access road.

18.5 Administration and Plant Site Buildings The location of the various site buildings is shown in Appendix 3. All offices, the

plant control room and the MCC buildings will be air conditioned using individual split system units.

The following buildings have been allowed for: ▪ Administration building ▪ Plant administration ▪ First Aid clinic ▪ Laboratory ▪ Security ▪ Mess room ▪ Ablutions/Changeroom ▪ Plant Warehouse/Workshop ▪ Reagents Day Shed ▪ Chemical and hazardous substance storage facility ▪ Goldroom ▪ Sub-station and MCC buildings Current exploration assay requirements are met by the contract laboratory located

at ALS Chemex laboratories in Rosia Montana, Romania and Vancouver, Canada. The plant laboratory will be able to process Amulsar plant samples. The on-site

laboratory will comprise sample preparation, fire assay, an atomic absorption spectrometer (AAS) for assaying plant and elution solution samples, and facilities for minor metallurgical testing (screen analyses, coarse bottle roll and column leach tests).

The laboratory will consist of an insulated metal clad shed adjacent to the

goldroom building.

18.7 Water Supply

A site-wide water balance study and hydrological assessment will be conducted as part of the BFS/ESIA studies. Water sourcing and the impact on other users will also be assessed. 18.7.1 Potable Water Supply

Potable water will be used for drinking water, ablution water, laboratory water and

safety showers. Potable water is not required for any process purpose.

Page 151: LYDIAN INTERNATIONAL, LTD. · 2015. 6. 15. · 1. I am an Independent Mineral Process Engineering Consultant and contributed to a Report entitled “Lydian International, Ltd., Development

Lydian International - Amulsar Heap Leach Facility Preliminary Economic Assessment Page 130

K D Engineering Document No. Q431-02-028 12 August 2011 KDE FORM No. A263a-7/12/99

The design potable water demand is 115 m3/day based on 300 l/person per day in the staff quarters and 40 l/day for staff not resident in the quarters. A further 70 m3/d will be required within the plant (ablutions, laboratory, safety showers, etc). Accordingly, a supply of 370 m3/d has been allowed and will be purchased from local community supplies.

18.7.2 Raw Water

Subject the findings of the water balance study and hydrological assessments, the

primary source of raw water will be from the Vorotan River. An abstraction permit will be required in accordance with Armenian legislation; however, there is no reason to suspect that this will not be granted.

Rainfall for the model was based on 40 years of daily rainfall records collected at

the Vorotan pass Climate Station located approximately 4 km from the site. Raw water will be used in the following areas at an estimated rate of 0.2 tonnes of

water per tonne of ore: ▪ Elution ▪ Reagent make-up ▪ Cooling water ▪ Process water make-up ▪ Dust suppression In order to minimise the number of services it is proposed to provide firewater via

the raw water system. A diesel driven pump will start automatically on loss of raw water pressure to provide a secure fire service. A minimum volume of water will be held in the raw water pond at all times.

For exploration drilling purposes Geoteam currently holds a water use permit from

a little pond on the western side of the pit. 18.8 Process Water Supply

The primary source of process water will be the Vorotan River. Process water

quality will be monitored and, provided it is acceptable, will be used in the following areas:

a. Leach pond make-up water b. Screen sprays c. Carbon transfer d. Process plant washdown

20.0 ENVIRONMENTAL STUDIES, PERMITTING AND SOCIAL IMPACT

Wardell Armstrong International Limited (WAI) was instructed by Lydian

International Limited (Lydian) to undertake a Scoping Study as part of the Environmental and Social Impact Assessment (ESIA) for the Amulsar open pit gold project in the southern part of the Republic of Armenia (RoA).

The scoping phase of the ESIA has been completed. Scoping requires the

gathering of preliminary information on the environmental context and the potential effects of the project. This enables the assessor to identify critical issues and provides an opportunity for early consultation with the local community and statutory authorities. The output of the scoping exercise is the ESIA Scoping Study report.

The purpose of the ESIA Scoping Study is to set out the main project parameters and identify any potential environmental and social impacts. It also sets out the national and international legislative framework and assesses the project status against international standards. Actions required have been identified in detail in a separate Gap Analysis. The main findings of these reports are summarised here, however, for completeness this report should be read in conjunction with the full versions of the Scoping Study and Gap Analysis (WAI Report No. EO-52-0088-1, dated February 2011).

The information presented below provides an overview of the environmental and

social conditions within the project area. It also identifies areas where extra work is required and planned.

20.1 Climate

The area is characterized by a temperate climate of long cold winters and short relatively cool summers. Climate data for the Vorotan River area are available from the Armenian State Hydro-meteorological Service (for the period of 1980-2010).

The maximum temperature in the summer is reported to reach greater than 30°C

and the minimum winter temperature is minus 28°C, with the coldest month frequently being January. April and May generally receive the most precipitation, with summer rainfall events capable of exceeding 60 mm/d. Evapo-transpiration rates are highest in July, with relative humidity being consistently elevated in winter months (December to March).

It should be noted that the preceding data has been averaged and sourced from a

lower elevation than the deposit. Site-specific data at a closer elevation to the open pit will be generated by the meteorological station recently installed at the open pit area and by a station established near HLP site 13.

Monitoring results indicate that annual air emissions did not exceed the maximum

allowable emissions standard established for the given source. Air emissions data collected throughout the year will continue to be documented into official logbooks. In addition, visual inspection of the bag-housings, and other control devices at the mine should be part of regular operational procedures and will be documented and reviewed by the Environmental Engineer as appropriate. 20.2 Water Resources & Quality

The project area contains numerous surface water features situated in the catchments of either the River Vorotan or Arpa. These comprise seasonal melt water rivers and permanent tributaries. The Vorotan flows through the license area to its outlet in the Spandaryan reservoir to the south.

At least one lake has been identified in the Exploration License area. The largest,

Moraine Lake, is currently abstracted to facilitate drilling activities. Wetland areas have been observed in the foothills and some of the proposed potential HLP sites.

A drinking water supply pipe and an irrigation surface channel divert water from the mountains and Vorotan River, through the Exploration License, to Gndevaz village. Groundwater resources in the project area have not been defined.

Samples from the Vorotan, Arpa and Darb Rivers and their tributaries, together with the Spandaryan reservoir and Gorayk drinking water supply are taken as part of the environmental monitoring and baseline data collection program (Refer to figure 20.1). Samples are tested for a wide range of physical, chemical and microbiological parameters.

Sporadic instances of nitrate, sulfate, Cu, Mn, Zn, Cr, Fe and V levels exceeding the maximum permitted concentrations (MPCs) have been noted. Other concentrations are predominantly below the detection limits, or 'limit of record' (LOR). The microbiological quality of the Gorayk water supply is poor for drinking water purposes, but a chlorinator has been supplied to upgrade it and will be supplemented by other treatment systems, as appropriate. The surface water sampling locations are shown in Figure 20.1.

During open pit mining there is potential for water inflow from two sources: precipitation and snow melt. Rainfall is generally more prolific during March to June. Seasonal water inflow from snow melts in spring, March to May.

Analysis of environmental baseline climate data from the on-site station will further characterize the likelihood and quantities of the above.

Figure 20.1 - Surface Water Sampling Locations in Relation to the License Boundaries

20.3 Hydrogeology

The spa town of Jermuk, to the north of the project produces bottled mineral water from groundwater resources.

Prior to fall 2010, no boreholes had been drilled at the project for the purposes of

groundwater monitoring. During the third and fourth quarters of 2010, three boreholes were drilled at the open pit site and each of three possible HLP sites and will be used to monitor groundwater characteristics and quality in these areas, refer to Figure 20.2.

Six springs have been identified in the area of open pit. Five of the six springs are located in the Amulsar watershed and on the eastern slopes. Groundwater and spring water were tested for physical-chemical and chemical parameters.

This testing will be continued in 2011. Archived data on groundwater (flow, pH, major components) has also been sourced from the Republic of Armenia Geological Fund.

Historically, state exploration boreholes are believed to have been dry to depth in

excess of 70 m below ground level at the open pit location, however, water is added to facilitate drilling, hence groundwater strikes are not recorded.

A spring-fed lake (currently used for exploration drilling purposes) is present in the Mining License. Although groundwater is not expected to be encountered by the open pit, other areas of the license may have a shallower groundwater table. There is currently no definitive physical or compositional data on the groundwater system within the Exploration License. These resources remain to be fully defined. A hydrocensus and groundwater impact assessment will be required in both the open pit and designated HLP areas. The impact assessment will consider other users and sustainability of sourcing. Surface and groundwater will therefore be the subject of further detailed hydrogeological and hydrological studies for the ESIA and BFS in order to characterize the regime, assess potential impacts and allow these to be negated, designed-out or otherwise managed as the project develops.

20.4 Land and Landscape Quality

The footprint area of mine development infrastructure remains to be finalized,

however, it is considered very unlikely that the land taken for the project will materially affect local landowners, occupiers or tenants given the high elevation of the project. Nevertheless, land use will be assessed in the context of flora and fauna, ethno botany, and economic usage of grazing pastures.

Given the remote location of the site and the limited population of villages in the

vicinity, there are not considered to be significant numbers of residents that would experience visual intrusion. However, the elevation of the property extends the range of visual effect, which increases the number of vantage points from which an operation may be visible. Jermuk is a tourist destination and consequently, particular attention will be placed on the analysis and reduction of visual impact of the project development. Photomontage will be used to assess potential impacts and reduction measures.

Many internal haul roads are already in place and the effect of widening of these

will also be considered. A traffic Impact assessment will also be carried out, to assist in the identification of approach routes and network assessment, as part of the ESIA.

Archaeological and biodiversity field studies are currently being done for summer

2011.

K D Engineering Document No. Q431-02-028 12 August 2011 KDE FORM No. A263a-7/12/99

Soil samples have been taken and analyzed for physical, chemical and biological baseline characterization purposes. Geotechnical and soil classification and distribution studies are continuing throughout 2011. 20.5 Potential In-Pit Water Flow During open pit mining there is potential for water inflow from two sources: precipitation and snow melt. Rainfall is generally more prolific during March to June. Seasonal water inflow from snow melts in spring, March to May. Baseline climate data from the on-site station will further characterize the likelihood and quantities of the above.

20.6 Seismicity Armenia is situated within the highly active Caucasus region in the vicinity of the Alpine-Himalaya seismic belt. The project is situated in an area of Armenia which is seismically active. Recorded earthquakes in the Zangezur region occurred in 1138, 1309, 1314, 1622, 1658, 1931, and 1968. The 1931 earthquake was registered as 8 on the Richter Scale and there were 50 fatalities in Syunik Marz. There is no detailed information on tremors in the project area. Detailed seismic assessments studies are planned for 2011 to aid in project assessment and design as part of the BFS.

20.7 Licenses and Permits

Subsequent to the exploration phase, and prior to development of the mine, several permits and licenses are likely to be required, including:

▪ Mining Licence ▪ Rock Allocation Area and change of land use status ▪ Technical Safety ▪ Water abstraction and discharge licence ▪ Air emission permit ▪ Change of land use in case the land is outside the RAA (the change takes up to

12 months for land outside the rock allocation area) ▪ Contract with Explosives Company, which has the permit to store, transport and

blast ▪ Contract with cyanide supplier and transportation companies that are fully

ICMC compliant. ▪ Construction and Architecture permits ▪ Gas and power use designs and construction expertise and permits ▪ Waste Passports ▪ Ecological Passport ▪ Environmental Impact Assessment to meet both national and international

requirements

20.8 Acid Rock Drainage (ARD) A Phase 1 ARD Characterization Program with respect to Amulsar waste rock has been carried out by WAI on 12 samples of potential waste rock, received from the Amulsar project in accordance with the agreed ESIA program. Waste rock types were identified by Lydian geological staff from batches of PQ drill core supplied to WAI for metallurgical testwork in 2010.

The screening assessments undertaken to date indicate that one waste rock, andesite porphyry, has acid-generating potential, and whilst the majority can be classified as non-acid generating, further studies and testwork will be required to verify these findings and further characterize the andesite porphyry and any borderline rock types.

The leachability testwork performed on these samples and the relatively low

leachability of all the inorganic components under TCLP conditions would indicate that dissolved metals would be below typical and regulatory levels (US EPA and Armenian Drinking Water Standards and accepted Toxicity Characteristic Regulatory Levels) should only low levels of acidity prevail.

A bespoke program of static analyses for the purposes of the ESIA waste rock

ARD impact assessment is underway and initial results, together with the requirement for kinetic testing and/or material management, will be available in Q3 2011. Detailed recommendations to enhance the ARD assessment to BFS level will also be provided. 20.9 Environmental Monitoring Program

Following the completion of the Scoping Study the terms of reference for baseline data gathering and monitoring have been further refined. Monitoring of environmental media will continue using a methodology designed by WAI and Lydian, informed by Armenian and International lender requirements. This program has been developed for the baseline stage of the ESIA. The submission of the draft ESIA will reflect the completion of the BFS, and is currently anticipated for Q2 2012. At construction stage and prior to operation, Lydian will transpose and modify this program so that it becomes adequate for on-going operational purposes.

The primary purpose of the current monitoring program is to assure that the project

remains in compliance with Armenian operating permits and environmental regulations and the IFC’s Performance Standards and to evaluate the effectiveness of the environmental mitigation measures. The results of the monitoring program are reviewed by project management on a periodic basis. If adverse environmental changes occur as a result of the project, appropriate remedial measures will be implemented to reduce or eliminate project-related effects. Specific details of any mitigation measures associated with unforeseen project-related effects will be developed based on the results of the monitoring. The current monitoring program contributes information to the environmental criteria for the baseline study in addition to monitoring on-site exploration and field activities.

K D Engineering Document No. Q431-02-028 12 August 2011 KDE FORM No. A263a-7/12/99

An on-site Environmental Officer is employed at the project to oversee the current baseline monitoring and mitigation programs, assure that permit stipulations are met, direct worker environmental training programs, and serve as the contact for environmental status reports and site inspections. In addition, there is a Health, Safety, Environmental and Community team currently engaged with the project. The current monitoring program and team provide a valuable platform for rolling-out a formal Environmental Management and Monitoring Plan (EMMP) to guide further development of project operations. Such a plan will be developed in parallel with the ESIA process and then taken on and extended to form the basis of a construction and operation relevant EMMP. 20.9.1 Meteorology/Air Quality

Historic climatic data for monitoring purposes can be obtained from the nearby Vorotan Pass weather station; this can be supplemented by the recently installed Lydian Meteorological Stations. Data obtained from this meteorological station will provide information such as precipitation data, to aid in the refinement of the project water balance for the mine pit and process facilities.

A noise and air quality monitoring program will continue to inform the baseline study and will then extend into the monitoring of construction and full-scale operations. Air quality monitoring will involve both the collection of ambient air samples, and daily inspection of engineered air quality controls on various facilities. For the collection of ambient air samples, specific sampling stations will be identified, so that they can be used year after year to help improve the consistency of the results.

Monitoring results should indicate that annual air emissions from the past year did not exceed the maximum allowable emissions standard established for the given source. Air emissions data collected throughout the year will be documented into official logbooks. In addition, visual inspection of the bag-housings, and other control devices at the mine should be part of regular operational procedures and will be documented and reviewed by the Environmental Engineer as appropriate. 20.9.2 Groundwater Monitoring

Monitoring of the groundwater wells commenced in Q3 2011 and will be conducted as outlined in Table 20.3, Water Monitoring Schedule. On a monthly basis, the groundwater monitoring wells will be measured for water level elevations. In addition, field water quality parameters will be determined, including temperature, pH, electrical conductivity, turbidity, dissolved oxygen and salinity. On a quarterly basis, groundwater monitoring wells will be measured for water level elevation, field parameters, and the parameters listed in Table 20.4, Water Quality Monitoring Parameters.

Additional groundwater monitoring wells will be established around the project area

for evaluating the groundwater hydrology and water quality at the site. The location, spacing, and depth of these wells will be such as to comply with existing Armenian regulations regarding the monitoring of groundwater flows around heap leach pads or other industrial facilities.

Page 161: LYDIAN INTERNATIONAL, LTD. · 2015. 6. 15. · 1. I am an Independent Mineral Process Engineering Consultant and contributed to a Report entitled “Lydian International, Ltd., Development

K D Engineering Document No. Q431-02-028 12 August 2011 KDE FORM No. A263a-7/12/99

A number of monitoring wells will be located around the Amulsar project site.

Specific locations for groundwater monitoring wells may be modified based on the results of more detailed hydrogeological evaluation of the project area.

Water quality data will be maintained on a database. This will allow for easy retrieval of the data, in addition to statistical evaluation of trends and parameters of interest.

20.9.3 Heap Leach Pad A monitoring program for the planned valley fill heap leach pad will be maintained to evaluate and document the performance of the leaching facility. This monitoring program is divided into the following parts:

▪ Geotechnical observations ▪ Hydrologic monitoring ▪ Water balance review

Page 162: LYDIAN INTERNATIONAL, LTD. · 2015. 6. 15. · 1. I am an Independent Mineral Process Engineering Consultant and contributed to a Report entitled “Lydian International, Ltd., Development

Lydian International - Amulsar Heap Leach Facility Preliminary Economic Assessment Page 141

K D Engineering Document No. Q431-02-028 12 August 2011 KDE FORM No. A263a-7/12/99

Geotechnical Observations

During operations, regular visual inspections of the heap pad and facilities will be made to check the condition of the embankments, liner, pipelines, and sprinkler facilities. Observations will be recorded in a field diary. Special attention will be given to any gullying and erosion, distinct changes in vegetation growth, plugged pipelines or drains, and the actual operation of any monitoring instrumentation. A record of such data will be maintained by the Environmental Engineer on-site. Hydrological and Water Quality Monitoring During operations the standard monitoring program will include hydrologic analysis for the following areas:

▪ groundwater ▪ leach collection system piping ▪ collection ponds

The general groundwater monitoring program for various facilities at the mine site was addressed above in Section 20.9.2, Groundwater. The groundwater monitoring program around the heap leach facilities will be designed to measure any changes in existing groundwater conditions down-gradient of the leach pad. Solutions in the collection ponds will be analyzed weekly for pH and cyanide as set forth in Table 20.3, Water Monitoring Schedule. Water Balance Review

A heap leach facility water balance will be developed on an annual basis as based on variations in operations and meteorological conditions. The heap leach pad and processing facility should be maintained using a closed circuit water supply. Monitoring of the water balance will serve to indicate if any significant and unexplained water losses or gains in this system are occurring. Such losses or gains could indicate seepage or other problems along the closed circuit water supply system.

20.9.4 Waste Rock Drainage

The ESIA acid rock drainage (ARD) impact assessment for Amulsar waste rock types will identify the potential acid- and leachate-generating rock types which can then be segregated and managed, if necessary, to prevent soil, surface water and groundwater contamination. Furthermore, to evaluate the chemical composition of the runoff and potential infiltration to groundwater from ARD from the waste rock dumps, monitoring groundwater quality down-gradient of the waste rock disposal or ore stockpiling areas will be conducted.

Acid rock drainage will be addressed for the waste rock dumps, ore stockpiles, and

mine pits. The parameters considered to be of greatest concern in potential waste rock

Page 163: LYDIAN INTERNATIONAL, LTD. · 2015. 6. 15. · 1. I am an Independent Mineral Process Engineering Consultant and contributed to a Report entitled “Lydian International, Ltd., Development

Lydian International - Amulsar Heap Leach Facility Preliminary Economic Assessment Page 142

K D Engineering Document No. Q431-02-028 12 August 2011 KDE FORM No. A263a-7/12/99

drainage will be: acid generating potential, blasting residuals (ammonium nitrate and fuel oils), and total suspended sediments (TSS).

During mining, water quality samples will be collected from groundwater monitoring wells, mine workings, and any springs or seeps that develop in the toe areas of the waste rock dumps or ore stockpiles. Field pH and conductivity will be monitored on a monthly basis in waters collected from groundwater monitoring wells down-gradient of these facilities. On a quarterly basis or as determined by seasonal constraints, detailed laboratory analyses will be obtained for these sites. The schedule for monitoring is shown in Table 20.3, Water Monitoring Schedule. Laboratory analyses to be conducted are presented in Table 20.4, Water Quality Monitoring Parameters. As part of the spring-and-seep surveys, a visual inspection of soils will be conducted for evidence of vegetation damage and/or mineral staining. Such surface expressions could be related to ARD and should be photographed and monitored for changes. Before it is placed in the dump, waste rock will be characterized by its mineralogy. Lithologies with a high potential to oxidize and create acid conditions will be encapsulated in materials with a high potential to neutralize acid, enclosures will be constructed, or other measures taken to minimize the potential for acid rock drainage. 20.10 Reclamation and Closure For a mining project to have a positive contribution to the sustainable development of a community or region, closure objectives and impacts must be considered from project inception. Closure and reclamation objectives include:

▪ Future public health and safety are not compromised; ▪ Environmental resources are not subject to physical and chemical deterioration; ▪ The after-use of the site is beneficial and sustainable in the long term; ▪ Any adverse socio-economic impacts are minimised; and ▪ All socio-economic benefits are maximised.

In accordance with international best practice for the mining industry and the

environmental policy of Lydian International Ltd, a conceptual MCRP will be developed for the Amulsar site during the BFS and environmental and social impact assessment (ESIA) phase of project design. Additionally, further work will be required in the detailed engineering design stage to refine the concepts and produce a Final MCRP, to ensure that the site is properly rehabilitated. At this stage of the project development, it is possible to state a commitment to:

▪ progressive rehabilitation of areas as they are worked, ▪ decontamination of affected sites; ▪ provide stability of physical and chemical environmental factors and; ▪ development of a detailed plan for eventual closure and implementation of

rehabilitation as the study proceeds.

Steps will need to be taken to ensure that funding is available to rehabilitate the mine upon closure and contribute to the long-term sustainable development of the area.

According to the Concession law of the Republic of Armenia, the design and cost calculation of reclamation works should be part of the designs and the environmental bonds should be paid, with 15% of the costs during the first year after the license is granted and the rest of the sum is divided onto the remaining years of the project. The Environmental bonds are paid on the special account in the Central Bank of Armenia.

Since the basic objective for the rehabilitation of any mineral operation is to achieve a long-term sustainable after-use of the site, Lydian International will develop a plan in accordance with the following seven principle objectives:

▪ minimise the area of land to be used for mining, processing and waste disposal which will require rehabilitation;

▪ ensure that opportunities for progressive rehabilitation of leach pads, waste

dumps, pits and ponds are identified, planned and programmed;

▪ construct landforms that provide long-term physical and chemical containment and stability of mine and process wastes that are acceptable to the regulatory authorities and are in-line with international good practice;

▪ avoid aspects of the mining and leaching operation and associated activities

that would make rehabilitation more difficult, costly or less effective;

▪ ensure that post-operation landforms are provided in a suitable form for the proposed final after-use;

▪ make certain that post-closure groundwater and surface water quality is

acceptable to the regulatory authorities and meet international standards;

▪ follow a consultative process, involving all interested parties, to determine the preferred after-use for the operational area and associated facilities.

Although the MCRP will primarily address closure on exhaustion of the mineable

resources and completion of processing of stockpiled ore, it must also provide for orderly decommissioning and rehabilitation should premature closure be required.

Decommissioning procedures for cyanide facilities will be integrated into the overall MCRP. Decommissioning and closure of cyanide facilities will entail the removal or detoxification of unused sodium cyanide and the clean-up of cyanide residues in process tanks and equipment. The specific measures to accomplish these tasks will be included in the MCRP, as should cost estimates and information on financial assurance for decommissioning and closure, in accordance with the International Cyanide Management Code (ICMC). All cyanide process tanks and piping systems should be triple flushed with water to remove residual cyanide, and the effluent routed to a detoxification circuit for reduction of residual cyanide concentrations to below EU standards, or other appropriate guidelines for cyanide in tailings. The decommissioned process plant tanks and piping systems should then be cut up for disposal or recycling.

Any decant water remaining in the solution ponds after process plant decommissioning should be pumped to the secondary cyanide treatment plant and treated. It is suggested that the water quality discharge standard be less than 0.1 mg/l total cyanide. However, approvals from the appropriate Armenian government will need to be agreed.

The MCRP for Amulsar will be integrated with annual action plans, especially with regard to environmental and socio-economic management issues. On-going reviews of the closure objectives and design are necessary to allow for changes in political, legislative, physical or socio-economic conditions. If planning is delayed, it may affect which mine closure objectives can be met. Guidance may therefore be required in carrying out periodic studies of closure options, to reduce the uncertainties and ensure that the MCRP remains adequate, realistic, appropriate and integrated within the whole operation life plan. Post-closure environmental monitoring and after-care will be required, in accordance with the established Environmental Management and Monitoring Plan (EMMP). This includes the monitoring of all sensitive receptors (including air quality, soil, groundwater and surface waters) in the project area and has been designed in accordance with international standards. Post-closure monitoring of groundwater in the vicinity of the heap leach facility will be of particular importance. The cost of environmental mining should be incorporated into the costed MCRP and will need to continue for a minimum of 5 years after rehabilitation of the site, in line with international best practice. The Armenian legislative requirements for post-closure monitoring will also be incorporated into the MCRP, as directed. 20.11 Social Context The project is located on the border of two Marzes (Vayots-Dzor and Syunik). Three villages with a total population of approximately 2 000 are potentially affected by the Project. These include the communities of Saravan (consisting of Saravan, Saralanj and Ughedzor (which is only inhabited during the summer months)) and Gndevaz both of which are in Vayots Dzor Marz some 5 to 9 km to the west of the deposit and Gorayk, located in Syunik Marz, 6 km southwest of the deposit. The closest city is Jermuk (which includes the village of Kechut), located 13 km from the project. With a population of approximately 6,200 people, the city is endowed with natural hot springs and waterfalls and is home to several national and international renowned health resorts and spas. Marzes are separated into different administrative centers, with Gorayk reporting into Sisian town in Syunik Marz and Gndevaz, Saravan and Jermuk reporting to Vayk in Vayots Dzor Marz. The nature of the anticipated impact varies for each community, as is summarized below. Detailed engineering for the project is ongoing, and as such, the final location for some facilities has not yet been confirmed. The impacts currently anticipated include:

K D Engineering Document No. Q431-02-028 12 August 2011 KDE FORM No. A263a-7/12/99

▪ Gorayk - Areas of seasonal pastureland will need to be acquired by the project to locate some facilities. Significant employment opportunities will be available to this village.

▪ Saravan - Packages of land will need to be acquired by the project to locate

some facilities. It is likely that the village of Saralanj will be able to see the project activities on the mountain. Significant employment opportunities will be available to this village

▪ Gndevaz - The project activities will likely be visible from Gndevaz. Significant

employment opportunities will be available to this village.

▪ Jermuk - Studies are being undertaken to determine the visual amenity impacts of the project upon Jermuk and mitigation plans will be developed once these studies are complete. Jermuk will also be the likely residence of many of the workers on the project as it develops.

20.11.1 Standard of Living, Infrastructure and Services In order to assess the standard of living in the study areas certain indicators are presented below: Income Table 20.5 shows the relative distribution of income brackets in the study area.

Table 20.5 Income Distribution in the Study Area

Percentage of Households Gorayk Saravan Gndevaz Less than US$ 191.001 per month 70.9 79.6 58.2 Between US$ 191,00- 273 per month 17.7 11.1 16.3 Between US$ 274 - 409 per month 7.6 1.9 14.9 More than US$ 510 per month 3.8 7.4 10.6 Source: MPG consultant survey, 2009 1 Conversion 1 US Dollar = 366.30 AD (Armenian Drams)

From the table it can be seen that in Gndevaz incomes are the highest. Agricultural

produce is the major source of income, accounting for 54.6 percent in Gndevaz, 69.6 percent in Gorayk and 75.9 percent, Saravan. Housing Most houses are made from stone with an asbestos roof. The majority consist of 3 or 4 rooms with a kitchen, bathroom and toilet in Saravan community outside the main structure. The dwellings in Gndevaz look to be in generally better condition than in the other villages.

K D Engineering Document No. Q431-02-028 12 August 2011 KDE FORM No. A263a-7/12/99

Infrastructure All communities have access to electricity, whilst only Gndevaz and Gorayk have access to piped gas, which they use for cooking. Saravan uses gas canisters or wood. All communities mostly use wood and dried manure for heating. All communities have access to piped water; however the quality of water in Gorayk and Saravan is sub-standard. The information of poor water quality of Saravan is based on people’s concerns, while the Gorayk water was tested and proved to be of poor quality.

There is no domestic waste removal or sewerage system in the communities except for Gorayk, where the waste removal is organized by Geoteam. Solid waste is mostly burned by households and what cannot be burned is disposed of by crude landfill in the valleys surrounding the villages. 20.12 Historical and Social-Cultural Situation In order to contextualize and provide a better understanding of the current communities of the study area a short historical description of each community is provided1: 20.12.1 Jermuk Ruins of an ancient fortress and an 8th century basilica testify to early human settlement in Jermuk. The foundation of the modern town of Jermuk, however, only took place in 1940, when the hot springs were discovered and the first sanatorium was opened to the public. Development programs were implemented to turn Jermuk into a modern resort for all Soviet nationals. In 1980 the population of Jermuk reached 10,000. After the collapse of the Soviet Union and as a result of the economic crisis in Armenia during the 1990s, the population dropped to 6000 (including the village of Kechut, which was included administratively into Jermuk in 1996) in the beginning of the 21st century. Recently however, the Armenian authorities took steps in order to further develop the Jermuk town-resort. As a result of those new resolutions the town has experienced unprecedented success as a tourist destination. 20.12.2 Gorayk The exact date of the foundation of Gorayk could not be established. However during the 18th century the village was populated by Russians (Malakans) who were resettled from Russia due to religious issues. During the period 1912 to 1914 Armenians from surrounding villages came to settle in Gorayk and by 1951 all Russian inhabitants had left. During 1965, under the soviet system, the original Gorayk village was flooded to create a reservoir (Spandaryan) and people were moved to the area where the village is currently located (2 km away from original spot). 1 Data for the historical background is gleaned from Wikipedia and discussions with local village chiefs.

Page 168: LYDIAN INTERNATIONAL, LTD. · 2015. 6. 15. · 1. I am an Independent Mineral Process Engineering Consultant and contributed to a Report entitled “Lydian International, Ltd., Development

K D Engineering Document No. Q431-02-028 12 August 2011 KDE FORM No. A263a-7/12/99

The current position however is not favored by the population. It is regarded as a swampy and damp area, unfavorable for agriculture and lacking clean water. 20.12.3 Gndevaz There is archeological evidence (caves) of human habitation from 2000 BC. In 1300, a village was founded, but in 1602 the population was chased away by an Iranian Shah. Despite this, in 1800 the village started to regrow with families from surrounding villages. An old church, Gndevank is located in the gorge next to the village which is found in 10th Century BC. The Church is regularly visited by tourists most of which are based in Jermuk.

20.12.4 Saravan

Saravan is a much more recent settlement founded in 1950. It was subsequently inhabited by Azerbaijanis in 1980.

After 1988, all Azerbaijanis left and Armenians returned. Currently 45% of the population consists of Armenian refugees who fled Azerbaijan during the war. 20.12.5 Socio - Cultural Aspects

To further provide insight into the social life of the local population, some pertinent socio-cultural aspects characterizing the communities are listed below:

Family life and family allegiance is the cornerstone of the local community. Often family units consist of different generations, with sons bringing their wives into the family home. Mother and daughter in law relationships are paramount, with the mother in law firmly managing the household assisted by daughters and daughters in law. Although women have an important role in the household, men are regarded as the head of the family and community affairs are predominantly managed by men. There seems to be little evidence of generation conflict, with young men and women performing their roles within the extended household. The lack of jobs however, forcing young people to search for jobs outside the village may change the generation dynamics.

Armenia prides itself as being the first country to declare itself a Christian state and local communities are all adherents of the Armenian Apostolic Church. The religion can be both of a cultural lifestyle and a strict doctrine with rules and regulations.

20.12.6 Health

In discussion with local residents and health professionals it was indicated that the main health problems in the area are: high blood pressure and related heart problems, osteoporosis, cancers, diabetes, urinary tract infections and seasonal health problems such as influenza in winter and bee stings and diarrhea (due to impure water) during summer. It was also indicated that TB was on the increase.

Lydian International - Amulsar Heap Leach Facility Preliminary Economic Assessment Page 148

K D Engineering Document No. Q431-02-028 12 August 2011 KDE FORM No. A263a-7/12/99

Clinics in the villages are first tier facilities, with the health post in Gorayk referring to the hospital in Sisian for more major health problems and Saravan, Gndevaz and Jermuk referring to Vayk. There are no pharmacies in the villages, the health posts however stock a number of basic medicines which can be obtained if the resident pays a quarterly adherence fee to the clinic and for free as well. Certain categories of patients (certain chronic ailments) are provided with free medication. The clinic staff is remunerated by the government and patients that are not included in special assistance groups are required to pay a consultation fee.

Armenian rural people have the reputation of being reluctant to visit a health facility and generally wait until problems have become serious health threats before seeking medical help. Minor ailments are often dealt with at home with herbal medicines. 20.12.7 Education

All three villages have a primary school and schooling is free. The number of students at schools is however low for the capacity of the buildings (Gorayk 70, Gndevaz 133, Saravan 30) and numbers are still decreasing, threatening the schools with closure. 20.12.8 Communications

Transport All villages can be reached by tar road. Gorayk and Saravan are located on the M2 highway (silk route), Gndevaz and Jermuk are on the H43 - H42. There is a regular bus service, connecting with Yerevan and other urban areas. Roads within the villages are un-tarred, dirt roads which are often in bad condition. A substantial number of households possess private cars. Communications

There is a daily newspaper delivery in all of the villages, however only few households use the service. There are several TV stations and mobile phone networks available as well as fixed telephone lines. Each village also boasts a post office. 20.12.9 Development Needs and Community Problems During the survey conducted in 2010 the following community needs were identified.

Table 20.6

Priority Needs in the Study Area Gorayk

▪ Asphalt surfacing of roads ▪ Restoration and repair of the Recreation center ▪ Rehabilitation and reopening of the kindergarten ▪ Establishment of a bulk purchase stock ▪ Operation of any industrial plant in the community ▪ Employment ▪ Waste collection and removal system ▪ Subsidies, support to the farmers for purchasing seeds and fertilizers

Saravan ▪ Asphalt surfacing of roads ▪ Irrigation water supply improvement ▪ Gas supply ▪ Street lighting ▪ Rehabilitation of the sewerage system ▪ Establishment of a purchase point

Gndevaz ▪ Asphalt surfacing of roads ▪ Rehabilitation of the water pipes ▪ Organization of entertainment ▪ Street illumination

Source: MPC consultant survey, 2010

From the table it can be seen that the main focus is on infrastructure improvement. Asphalting of village roads and improvement of sewerage systems are a priority in all villages. Further to the table above employment and improved marketing facilities were repeatedly identified as priority needs.

Geoteam has been supporting community development activities in the three

villages since 2006 and more recently including Jermuk. Activities have included supporting the extension of a gas pipeline into Saravan, job creation through support for new enterprises (eg sewing of sample bags), supporting students that study Geology and Mining Engineering at the Universities of Armenia, refurbishment of a number of community facilities, and partnering with NGOs to extend development programs into the region (eg Kinderwall). 20.13 ESIA Recommendations and Scope of Works

A work plan covering all of the issues identified has been formally developed between Lydian/Geoteam and WAI and work is progressing against each of these topics. WAI has recommended that the scope of ESIA baseline and assessments to quantify and/or mitigate against environmental and social issues identified include:

▪ Groundwater and surface water hydrology, quality and sustainability - further hydro-geological study, modelling and geochemical assessment via the installation of monitoring wells needs to be undertaken. Site-wide water balance calculations need to be determined and the sustainability of sourcing examined and managed;

Lydian International - Amulsar Heap Leach Facility Preliminary Economic Assessment Page 150

K D Engineering Document No. Q431-02-028 12 August 2011 KDE FORM No. A263a-7/12/99

▪ Visual impact – The visual impact of the project needs to be assessed from

Jermuk, the public highway and village communities, with the results included in public consultations;

▪ Traffic - quantification of mining traffic and a traffic impact assessment is

required;

▪ Land disturbance and take - a land use survey, biodiversity assessment and archaeological study are required to inform an impact assessment and assessment of any compensation required for grazing lands;

▪ Biodiversity - field surveys need to be undertaken on areas of major

disturbance. An assessment of flora harvested and collected by villagers is required. These studies will inform an overall impact assessment;

▪ Dust - dust dispersion modelling and impact assessment on edible plant

species used by the communities needs to be undertaken;

▪ Noise - Noise impact modelling, incorporating the operating specifics of mine fleet and machinery needs to be undertaken to inform the noise impact assessment on nearest sensitive receptors;

▪ Cyanide and hazardous materials - As the project will use cyanide in its

heap leach process, the usage, transport, handling and disposal of cyanide will need to be managed via formal plans and procedures in accordance with international best practice, particularly the International Cyanide Management Code (ICMC);

▪ Waste rock - acid- and leachate-generating potential of waste rock types is

being assessed via a program of geochemical testwork. Environmental protection measures and/or management techniques will be incorporated in dump design, if needed;

▪ Local labour - high unemployment and expectations require careful

management and a Skills Audit to assess future potential employment opportunities should be undertaken;

▪ Social Baseline - supplemental demographic surveys and a health baseline

assessment (to include seasonal visitors) need to be undertaken;

▪ Local Industry - further appraisal of the main (agricultural and manufacturing) sectors is required, including individual contributions to domestic income. An assessment of potential diversification and increase in access to markets with advent of mining is considered beneficial;

▪ Public disclosure and consultation - to be undertaken in line with

international best practice, at all stages of the ESIA and mine development

processes (to include Jermuk) to manage expectations, allay concerns, establish NGO partnerships, inform community development and spending and influence mine design;

▪ Closure – considerations need to be addressed from conceptual stage via

the preparation and continual update of a Mine Closure and Rehabilitation Plan (to include heap leach rehabilitation).

WAI propose to monitor and review the process of environmental and social

baseline data collection by Lydian/Geoteam, and general progression of the ESIA works, and provide continuing technical support, as required, to ensure that both national and international requirements are met. The baseline programme is continuing and the next ESIA deliverable will be a baseline status report in Q3 2011.

WAI will also work closely with the BFS team to ensure that environmental and

social issues are taken into account with the design and siting of all major infrastructure and that appropriate alternatives are considered and/or mitigation and management measures are employed to ensure that impacts are addressed. It is therefore recommended that a time-bound, integrated ESIA and BFS schedule of works is prepared to facilitate this process.

WAI will need to ensure that the public consultation, which will be undertaken for

the purposes of the ESIA, will include available information from the BFS so that project stakeholders have the opportunity to input into the process.

The direct costs exhibited in this estimate include, but are not limited to, labor, equipment and materials for the detailed construction activities set forth below: Equipment Costs An equipment list was developed and incorporated into the cost estimate. The estimate for equipment was developed from the following sources:

▪ Written or e-mailed budgetary estimates from vendors for major equipment. ▪ Budget unit costs were provided from a local contractor for building costs. ▪ Historical data and budget costs of similar projects for miscellaneous

equipment.

Moreover, the cost of “Installed Equipment” was estimated using a forty-three percent (43%) factor. Site Development Site development costs include excavations and back fills calculations using preliminary plans and historical data for similar plants. The initial phase cost was estimated using a twenty-five percent (25%) factor of the installed plant equipment cost. The factor was reduced to one (1%) for the second phase. The Project will require development at the following major locations:

▪ The mining areas ▪ The crushing plant area including administration and contract laboratory ▪ The mine services area, including the mine administration building, mine

workshops, refueling area, mine control areas and explosives yard ▪ The leach pad and storage ponds

Fresh, Raw and Process Water Fresh, raw and process water is discussed in Section 18 of this report. Electrical and Instrumentation Electrical and instrumentation are included using historical data for similar plants. Emergency powered generators have been included to continue to supply power to critical pieces of equipment (thickener mechanisms, agitators, etc.) in the event of a power outage. An estimate for a power line installation and substation from the local Electrical Utility is included in the factored estimate. Power Supply to Mine Power is not currently provided to the Project site although domestic usage power is available at neighboring main towns to the south and east. The supply of

power in this region is controlled by the Armenian Electrical Networks company (ANE) and will be stepped down at ANE owned substations and delivered to the mine and plant site. A small hydroelectric power plant is being developed on the Vorotan River to the NE of the Amulsar mine site which will have a total installed capacity of 1.8 to 2 MW. This is expected to be in operation in Q3 2011. The costs for Water (Fresh, Raw & Process) and Electrical Power (Electrical Instrumentation & power supply) to the site were estimated using a fifteen percent (5%) factor of the installed plant equipment cost. 21.3.2 Indirect Costs Certain indirect costs exhibited in this estimate include, but are not limited to, labor, equipment and materials for the detailed activities set forth below:

▪ EPCM for the initial phase were estimated using a twelve percent (12%) factor of the installed plant equipment cost. The factor was reduced to seven percent (7%) for the second phase and includes:

- Detailed Engineering - Procurement - Construction Management - Training

▪ Construction Indirect Costs for the initial phase were estimated using a ten

percent (10%) factor of the installed plant equipment cost and includes:

- Construction Supervision - Equipment Rental - Field Office Expenses - Mobilization/Demobilization - Consumables

▪ Spare parts costs were estimated using a five percent (5%) factor of the

installed plant equipment cost.

▪ Initial Fill & Reagents costs were estimated using a one and half percent (1.5%) factor of the installed plant equipment costs.

▪ Equipment Insurance and Freight costs were estimated using a seven

percent (7%) factor of the installed plant equipment costs. 21.3.3 Contingency and Accuracy

The KDE crushing and process plant portion of the cost estimate includes a 30 percent contingency for project unknowns and identified risks. Contingency is a

necessary part of the cost estimate and KDE utilized 30 percent based on the fact less than 5 percent of the engineering is completed to date. KDE believes the estimated contingency amount will be spent during the life of the project for identified risks and unknown items. While KDE has not performed a statistical analysis of the crushing plant and process plant accuracy of the capital cost estimate we believe based on previous experience with similar projects there is a high confidence that the accuracy of the process portion of the PEA capital cost estimate will end up between -10 percent and +35 percent of the KDE capital cost estimate. 21.3.4 Exclusions KDE has excluded the following items from the process plant estimate and they are included elsewhere:

▪ Permits, royalties and licenses ▪ Environmental testing and monitoring ▪ Metallurgical testing ▪ Escalation and Insurances ▪ Taxes, duty and import fees ▪ Solution and ponds ▪ Mining costs ▪ Reclamation and closure costs ▪ Geotechnical design and facility costs ▪ Camp Costs ▪ Allowance for design growth or specification changes

21.4 Process Operating Costs Annual and unit process operating cost estimates for Phase I (5 million tonnes per year) and Phase II (10 million tonnes per year) process operation are summarized in Table 21.5. Support Tables for the cost estimates are shown in Tables 21.6 to 21.10.

22.0 ECONOMIC ANALYSIS

A pre-income tax economic analysis model was prepared. The model uses the production and cost estimates shown earlier in this report. Costs are in 2011 constant dollars. The economic analysis uses a gold sales price US$ 1,200 per ounce and a silver sales price of US$ 20.00 per ounce and plant estimated recoveries of 85 percent for gold for all PMM grades processed and 40 percent for silver based on a nominal average grade. Operating cost estimates and values for key design parameters that have been presented in previous sections of the PEA were used as required. The economic analysis was done on an all equity financing basis. Four different scenarios were prepared, they are;

1. Owner operating mining 2. Contract mining 3. Owner operating mining with Erato resource ounces 4. Contract mining with Erato resource ounces

22.1 Owner Operating Mining Case Table 22.1 shows the project's owner operating mining pre-income tax internal rate of return and the project's pre-income tax net present values at discount rates from 0 to 20 percent.

Table 22.2 summarizes the project's revenue, costs and pre-income tax cash flow and also shows the values in units of resource processed and saleable gold ounces.

As seen in Tables 22.19 and 22.20, the project's contract mining with Erato case pre-income tax rate of return is 46.0 percent and the project's contract mining case pre-income tax net present value at a 5 percent discount rate is US$ 592.6 million. A ten percent increase in the gold price increases the estimated rate of return to 52.6 percent and increases the project's net present value, at a 5 percent discount rate, to US$ 735.5 million.

23.0 ADJACENT PROPERTIES The following adjacent properties information is taken from the NI 43-101 report dated 19th May 2011 mentioned in the Introduction of this report. Lydian’s discovery of the gold-bearing epithermal system at Amulsar remains the only significant new mineral discovery in Armenia since the country’s independence from the Soviet Union. Metal production comes from the Kadjaran (Cronimet) and Agarak (GeoProMining) copper-molybdenum porphyry deposits and the Kapan vein-type polymetallic deposit (Dundee Precious Metals) in the south and the Shahumyan polymetallic deposit in the north, although these have been adversely impacted by the metal price slump of late 2008-09. Gold deposits known to date are primarily hosted in veins and brittle shear structures - the Zod gold mine (GeoProMining) in eastern Armenia is an example of the latter, but gold is also present as an accessory mineral in some polymetallic deposits. Other exploration companies active in Armenia include Global Gold, Caldera Resources, Anglo African Minerals and Vallex who are the largest Armenian mining company. There are no competitors exploring for gold in the immediate area around Amulsar, although a small locally owned silver mining licence is located on the northwest of the Amulsar licence area.

25.0 INTERPRETATION AND CONCLUSION

As a result of considerable effort by Lydian employees and geological, mining, geotechnical, mineral processing, and environmental consultants sufficient technical information is available to produce this Preliminary Economic Assessment. This engineering study qualifies as a PEA level document according to Canadian National Instrument 43-101. The economic models utilized in this report indicated a range of before tax rate of return from 39.5 to 46.0 percent at an assumed gold price of US$ 1,200 per ounce. If the gold price used in the economic evaluation, which excludes inferred resources, is increased to current levels (US$ 1,500 per ounce in July 2011) then the before tax rate of return ranges from 54.7 to 61.8 percent. 25.1 Mining

Based on the optimisation work that has been completed, using the input parameters provided by Lydian, the Amulsar gold deposit has the potential to be a financially viable operation.

The conversion factors from resources to PMM are favourable for both the Indicated resources only option and the Indicated and Inferred resources option. As the optimisation pit shells reach both the lateral and lower extents of the current resource, this indicates that exploration should be extended both laterally and at depth.

The initial optimisation work indicates that a portion of the resources which are currently classified as Inferred have the potential to be economically mineable. Further drilling should therefore be carried out on this portion of the Inferred resources to bring them to the Indicated Category.

The chosen Amulsar Whittle optimisation shell for the Indicated resource only option contains 31.0 million tonnes of PMM (allowing for 5% losses and 5% dilution) at an average head grade of 0.98 g/t and 75.9 million tonnes of waste, resulting in an overall strip ratio of 2.45:1. The selected pit shell provides a “specified discounted cashflow” of US$263.75 million with two push backs. These figures exclude capital expenditure.

The chosen Amulsar Whittle optimisation shell for the Indicated and Inferred resource option contains 53.6 million tonnes of PMM (allowing for 5% losses and 5% dilution) at an average head grade of 0.94 g/t and 138.0 million tonnes of waste resulting in an overall strip ratio of 2.57:1. The selected optimum pit shell provides a “specified discounted cashflow” of US$367.08 million with two push backs. These figures exclude capital expenditure.

The level of confidence in the Scoping Study completed to date would not support the presentation of a Reserves Statement for the Amulsar Project.

After applying reasonable factors for losses, mining recovery and dilution, the following estimates of potentially mineable mineralization (“PMM”) can be proposed:

Conventional Open Pit Mining (Tigranes area and Artavasdes area)

PMM based on Indicated resources 36.5 Mt @ 0.92 g/t Au

PMM based on Inferred Resources 18.8 Mt @ 0.93 g/t Au

In addition to the figures quoted above, there is the potential for extensions to the Amulsar PMM to the north in the Erato area. Sensitivity analysis undertaken during the Optimisation studies has indicated this additional mineralisation would have a positive effect on the project financials.

The studies to date have not indicated any major difficulties or costs in establishing the necessary infrastructure facilities to support the operation.

Enquiries in Armenia have indicated that there are currently no contract mining companies in Armenia with the capacity or equipment to satisfy the Amulsar production schedule. Enquiries have also shown that the purchase of haul trucks greater than 180 tonne capacity in Armenia will be challenging. As a result, this study has only utilised haul trucks smaller than 180 tonne capacity.

An optimisation utilising the final PEA financial and physical parameters reported results in line with the earlier optimisations completed in the former stages of the study.

25.2 Metallurgical Testing and Mineral Processing

Results of past test programs revealed that heap leach gold extraction was influenced by particle size distribution. Test data and heap leach projections indicated that acceptable gold extraction rates and levels required crushing the gold ore to a size distribution of 80 percent passing 12 millimeters. Based on this information, an equipment assemblage was developed to crush and leach an average of 30,000 tonnes per day of ore at the size distribution mentioned above.

The Amulsar ore body is low grade. Preliminary studies completed to date indicate that it is unlikely that gold could be economically extracted if fine grinding was required as part of a beneficiation scheme. The differential gold extraction between heap leaching and fine grinding plus agitated leaching would likely not offset the capital and operating cost increases imposed by grinding. However, additional work is required to eliminate agitation leaching as a beneficiation technique.

Additional work will be devoted to infrastructure components including power acquisition, road upgrading, raw water procurement, and the leach pad and pond location. The major project risk is due to the fact that there are no existing heap leach gold mines currently operating in the country. Therefore there are also limited manpower resources available to operate the facilities. On a positive note, the Amulsar gold ore does not contain any deleterious elements and with appropriate training it is anticipated that operations will reach acceptable efficiencies.

25.3 Environmental and Social

A number of environmental and social issues were identified through the scoping

exercise and public consultations. The social and environmental issues identified were not prohibitive but will form a focal point for further baseline studies in order to better characterise them and to provide information on how they might be mitigated. Risks will also be directly addressed via assessments, consultation and the preparation and implementation of relevant management plans.

The findings of the Scoping Study and the terms of reference for continuing work

were presented, in May 2011, to the neighbouring communities as part of the public consultation and disclosure process. Key issues and observations were noted and appropriate actions have been incorporated in the proposed ESIA scope of programme of works. Lydian has commissioned several discrete studies in response to the findings of the Scoping Study and public consultation undertaken and has pledged support and resources to the actions identified.

26.0 RECOMMENDATIONS

The following opportunities were proposed by the client and their consultants to further reduce the overall capital or operating costs:

Mining

Formulate a Project Development Schedule, in line with corporate objectives,

that defines a Staged Study approach with associated data collection phases. The scope of work for each study phase should be clearly defined.

It is recommended the key technical data collection for the next phase would

include:

▪ Additional drilling to better define the structure and anomalies in the Amulsar deposit and expand and reclassify the resource base

▪ Geotechnical drilling, test work and analysis

▪ Hydrogeology test work and modelling

▪ Drilling to collect a representative sample for metallurgical testwork.

Mineral Processing

Additional metallurgical testing will be required to fully define the different

possible leaching techniques to economically process the Amulsar ores. An extensive column leach test program should be conducted at METCON Research or similar laboratory.

Crushing

Further studies to improve the economics include the following:

▪ Contract Mining verses Owner operated mining ▪ Further review of phased or ramp up of the production rates ▪ In-pit crushing ▪ Single primary gyratory crusher verses two jaw crushers ▪ Further review the topography to minimize earthwork, foundation and

conveying costs

Leach Pad and Metal Recovery

▪ Finalize leach pad location and construction schedule ▪ Identify required process water resources ▪ Finalize process plant location

Infrastructure

Review access road costs, with equipment that will be onsite there is a good chance that the road construction could be reduced by combining project with overall construction including the leach pad and ponds. Power

Further review to define the closest source from the local Armenian grid power.

Review the best options to get power to site and begin negotiations with the Armenian power utility company to further economize the design options. Environmental and Social

A work plan covering all of the issues identified has been formally developed

between Lydian/Geoteam and WAI and work is progressing against each of these topics. WAI has recommended that the scope of ESIA baseline and assessments to quantify and/or mitigate against environmental and social issues identified include:

▪ Groundwater and surface water hydrology, quality and sustainability -

further hydro-geological study, modelling and geochemical assessment via the installation of monitoring wells needs to be undertaken. Site-wide water balance calculations need to be determined and the sustainability of sourcing examined and managed;

▪ Visual impact – The visual impact of the project needs to be assessed from

Jermuk, the public highway and village communities, with the results included in public consultations;

▪ Traffic - quantification of mining traffic and a traffic impact assessment is

required; ▪ Land disturbance and take - a land use survey, biodiversity assessment

and archaeological study are required to inform an impact assessment and assessment of any compensation required for grazing lands;

▪ Biodiversity - field surveys need to be undertaken on areas of major

disturbance. An assessment of flora harvested and collected by villagers is required. These studies will inform an overall impact assessment;

▪ Dust - dust dispersion modelling and impact assessment on edible plant

species used by the communities needs to be undertaken; ▪ Noise - Noise impact modelling, incorporating the operating specifics of mine

fleet and machinery needs to be undertaken to inform the noise impact assessment on nearest sensitive receptors;

K D Engineering Document No. Q439-03-028-01 12 August 2011 KDE FORM No. A263a-7/12/99

▪ Cyanide and hazardous materials - As the project will use cyanide in its heap leach process, the usage, transport, handling and disposal of cyanide will need to be managed via formal plans and procedures in accordance with international best practice, particularly the International Cyanide Management Code (ICMC);

▪ Waste rock - acid- and leachate-generating potential of waste rock types is

being assessed via a program of geochemical testwork. Environmental protection measures and/or management techniques will be incorporated in dump design, if needed;

▪ Local labour - high unemployment and expectations require careful

management and a Skills Audit to assess future potential employment opportunities should be undertaken;

▪ Social Baseline - supplemental demographic surveys and a health baseline

assessment (to include seasonal visitors) need to be undertaken; ▪ Local Industry - further appraisal of the main (agricultural and

manufacturing) sectors is required, including individual contributions to domestic income. An assessment of potential diversification and increase in access to markets with advent of mining is considered beneficial;

▪ Public disclosure and consultation - to be undertaken in line with

international best practice, at all stages of the ESIA and mine development processes (to include Jermuk) to manage expectations, allay concerns, establish NGO partnerships, inform community development and spending and influence mine design;

▪ Closure - considerations need to be addressed from conceptual stage via the

preparation and continual update of a Mine Closure and Rehabilitation Plan (to include heap leach rehabilitation).

WAI propose to monitor and review the process of environmental and social

baseline data collection by Lydian/Geoteam, and general progression of the ESIA works, and provide continuing technical support, as required, to ensure that both national and international requirements are met. The baseline programme is continuing and the next ESIA deliverable will be a baseline status report in Q3 2011.

WAI will also work closely with the BFS team to ensure that environmental and

social issues are taken into account with the design and siting of all major infrastructure and that appropriate alternatives are considered and/or mitigation and management measures are employed to ensure that impacts are addressed. It is therefore recommended that a time-bound, integrated ESIA and BFS schedule of works is prepared to facilitate this process.

WAI will need to ensure that the public consultation, which will be undertaken for the purposes of the ESIA, will include available information from the BFS so that project stakeholders have the opportunity to input into the process.

Project Planning

▪ Commence work on a project operating plant and project execution plan ▪ Collect local and international unit construction/fabrication and supplies/labor

costs. ▪ Investigate mine equipment leasing and project financing plan

Next Stage Budget and Schedule

The authors of this report are of the opinion that the character of the Lydian’s

Amulsar Gold Project is of sufficient merit to commence with BFS beginning in August 2011.

It is recommended that the project be advanced to the BFS stage. Costs for this

level of study are estimated as follows:

US$Mine Design 220,000Mineral Processing & Infrastructure 366,254Leach Pad, Ponds, Pit Slopes & Hydrology 570,186Hydro-geological 189,099Seismic 77,285

Total 1,422,824

It is estimated that a final Lydian BFS will require 6 to 8 months to complete.

The following criteria have been developed to support the Preliminary Economic Assessment (PEA) study for LYDIAN INTERNATIONAL Ltd. at the Amulsar property in

Armenia. Precious metals will be recovered from low grade material by heap leaching. To prepare the ore for leaching, a crushing plant is planned. In Phase I, the ore

will be processed through the crushing plant at 5 million tonnes per year; Phase II will expand the facility to process 10 million tonnes per year. Crushed ore will be

deposited on the heap using a conveyor - stacker system and will be leached with a dilute cyanide solution in the conventional manner. Precious metals will be

recovered from the leach solution by adsorption on activated carbon. The precious metals will be periodically desorbed from the activated carbon and the stripped

carbon will be reactivated. Precious metals will be recovered from the strip solution by electrowinning. The product from electrowinning will be dried and smelted to

produce dore bullion which will be shipped from the site to refiners.

Phase II (10 Million Tonnes per year)Phase I (5 Million Tonnes per year)

European codes, standards and regulations will be used. Applicable codes, standards and regulations will be referenced in each Technical Specification that is

applicable for the particular piece of equipment or system that is being designed. Specific design standards will be referenced, as required, in each Technical

Specification.

Amulsar is located 170 km from Yerevan, Armenia and 6 km from Gorhayk village.

Site is located in a relatively high seismic risk area

PGArock between 0.4g and 0.5g for a seismic event

with a 10% probability of exceedance in 50 years (475-

Increasing throughput from 5 to 10 million tonnes per year will entail installation of duplicate equipment for a majority of the processing unit operations.

Run-of-mine ore will be hauled by truck to the crushing plant area by rear-dump trucks and dumped into a crusher feed hopper. An open stockpile is provided adjacent

to the crusher so trucks can dump if the crusher is not available. A single crushing line will process the design tonnage at the indicated average daily throughput noted

below. The line consists of a dump hopper, apron feeder, stationary grizzly, rock breaker, jaw crusher and associated transfer equipment. The primary crusher reduces

the size of run-of-mine ore from a maximum of 700 mm to approximately 80% passing 175 mm. Crushed ore drops onto a belt conveyor and transported to the coarse

ore storage bin. Apron feeders and a transport conveyor feed the coarse to to a double deck scalping grizzly to remove undersize material. Vibrating screen oversize is

fed to the secondary cone crusher. Secondary and tertiary crushed product are conveyed to the fine ore screen feed bin. Fine screen oversize at plus 14 millimeter is

fed to the tertiary crushers. Fine screen undersize is the crushing circuit product and is transported by agglomeration by belt conveyor. Lime, required for pH control, and Portland cement, required for agglomeration, will be added to the transfer convey

The crushed ore will be stacked on the pad using conveyors and a slewing and luffing stacker. A bulldozer will be used to rip and crossrip the heap surface before

placement of a new lift of ore.

Pregnant solution from the leaching process will be pumped from the pregnant solution pond to a carbon Adsorption-Desorption-Recovery (ADR) plant to recover the

gold from solution. Adsorption will take place in one train of 5 carbon adsorption columns in series. Solution will flow from each adsorption stage to the next stage by

gravity. Carbon will be advanced countercurrent to the solution flow by a carbon advance pump. Barren solution discharging from adsorption will flow to a barren pond

from which it will be pumped to the ore heap for further leaching. High strength cyanide solution will be injected into the barren solution to maintain the cyanide

concentration at the desired level.

Precious metals will be recovered from the strip solution by electrowinning. When the electrowinning cell is appropriately loaded with gold and silver, the stainless steel

wool cathodes will be washed with high pressure water inside the cells to flush the precious metal sludge from the cathodes. The precious metals sludge slurry then flow

to a holding tank and to a pressure filter. The stripped cathodes will be returned to the electrowinning cells. The filter cake will be treated in a retort to dry the cake. The

dried product from the retort will be smelted in an induction furnace and poured into 500 oz to 1000 oz Dore bars. The Dore bars will be shipped to commercial facilities

for refining.

The stripped carbon will be transferred by pressure eduction from the elution column over a screen and into the reactivation furnace feed tank. Carbon reactivation will

be accomplished in an electric rotary kiln-type furnace.

3

An installation for mixing and adding reagents to the process and elution circuits and a system for adding new carbon are included in the process design.

Loaded carbon from the adsorption circuit will be transferred to the acid wash vessel. The acid will be removed from the carbon by washing with fresh water. After acid

washing, the carbon will be pumped to the elution vessel. The pressurized Zadra process will be used for gold elution. Hot strip solution will be circulated through the

carbon elution vessel to desorb the precious metals from the carbon.

The primary crushing line consists of dump hopper, apron feeder, grizzly screen, rock breaker, crusher and associated dust collection and transfer equipment. Run of Mine (ROM) ore is

dumped into the dump hopper. The apron feeder screen transfers the ore at a controlled rate to the grizzly screen. The screen oversize feeds the jaw crusher. A rock breaker is available to

service the crusher or screen. The crusher reduces the size of run-of-mine ore from maximum 700 mm to approximately 80% passing 175 mm. Crushed ore drops onto a belt conveyor that

transports the crushed ore to a crushed ore storage bin. A bin is used instead of a coarse ore pile due to the extreme wind and potential dust loss.

Dust is controlled in the dump pocket with water sprays and bin vents service at the contained transfer points.

Run-of-mine ore is transported to the crushing plant area by rear-dump trucks and dumped into a crusher feed hopper. An open stockpile is provided adjacent to the crusher so trucks can

dump if the crusher is not available. One crushing line will be required to process 5 million tonnes per year, while two parallel crushing lines are required to process 10 million tonnes per year.

Two parallel secondary crushing trains are provided for 2 x 5 million tonnes per year. Each train will pull ore from the same coarse ore bin, so that some ore can be crushed through all

secondary and tertiary crushers even if one of the jaw crushing lines is down. The bin discharge is fed to a double deck scalping screen to remove fines from the secondary crusher feed.

Crushed product and the screen undersize are conveyed to the fine ore screen feed bin.

Screen Oversize

Secondary screen undersize and secondary and tertiary crusher discharge are fed to the tertiary screen feed bin by a tripper conveyor. The bin has discharge conveyors that feed the tertiary

screens. Screen oversize is conveyed by a tripper conveyor to the tertiary crusher feed bins. Screen undersize is conveyed by a tripper conveyor to the fine ore load out bin.

Crushed ore at minus 12 mm is fed to a drum agglomerator where it is mixed with cement and leach solution. Cement addition is varied with the ore tonnage and ore placement in the heap

based on input from the operations staff. Cement is trucked to the site and unloaded in an on site storage silo. The cement is metered from the silo to the agglomeration feed conveyor by a

rotary valve.

The following criteria describe the precious metal recovery plant. Pregnant solution is pumped to the carbon columns. One train of five stages in series are installed. The train will be

stepped down to allow gravity flow of solution from stage to stage. Carbon will be advanced counter currently through the columns using a recessed impeller pump mounted external

to the carbon columns. Carbon pump suction and discharge can be controlled by automatic valves so one pump serves all CIC tanks in the train. Loaded carbon from the number 1

column will be pumped to a dewatering screen which will discharge the carbon into the loaded carbon storage bin.

Barren solution from the number 5 column will flow through a wire sampler and over a vibrating safety screen. The solution from the safety screen will flow to the barren solution tank,

where the cyanide strength will be increased to the concentration required for leaching by adding 20 percent cyanide solution. Barren solution will be pumped through flow meters and

returned to the leach solution distribution system through a pipeline

Total Loaded Carbon

Carbon loaded with precious metals is processed in the Carbon Desorption circuit. As outlined below a pressure Zadra system is planned.

Air is required for the crushing and ADR plant operation. Two separate systems, one in each area are planned.

The raw water distribution system provides raw water for process requirements such as process water makeup, reagent mixing, and gland water. The top portion of the mine head tank will

be used to provide raw water surge for the system. The bottom portion of the mine head tank will provide the fire water storage for the system.

The potable water distribution system provides well water for safety showers and other uses as required. A small head tank located near the raw water head tank will be used to provide

surge and head for the system.

The process water loop includes pumps and piping to provide process water in the plant area. The process water will be pumped to all ADR process areas and may contain solids and other

chemical contaminates. The water is used to facilitate carbon movement.
