SUMMARY

Nine sub-blocks relinquished from EPM 13932 in June 2006 were explored for gold.

Methods used included geophysical interpretation and mineral occurrence evaluation. The

areas are predominantly underlain by Palaeozoic granitoids which are locally covered by

Tertiary laterites and recent alluvium. Only one un-named prospect is reported by GSQ to

occur in the area of the relinquished sub-blocks (GSQ 292702).

1.0 Introduction

The nine relinquished sub-blocks are in two groups and are centred 15 km SW (4 sub-

blocks) and 10 km SSE (5 sub-blocks) from the centre of Charters Towers, Queensland,

(Figure 1). Charters Towers is located about 105 km SSW of Townsville. Landforms

comprise low hills and plains within the Burdekin River catchment.

The tenement lies on the Charters Towers 1:100,000 Sheet Number 8157. Access is

generally good via a network of formed roads. The area is held as grazing properties.

The Charters Towers goldfield is world class, having produced 6.6 million ounces of gold at

a grade of over 1 ounce to the tonne.

The objective of Citigold’s exploration on the EPM was to delineate mineable gold resources

for processing at the Black Jack treatment plant. Citigold’s existing infrastructure would

facilitate the early development of any viable gold deposit located in the tenement area.

2.0 Tenure

EPM 13932 was granted on 23rd of June 2003 to Charters Towers Gold Mines Ltd

(CTGM). In November 2003 CTGM changed its name to Citigold Corporation Ltd.

Nine sub-blocks were relinquished on 22nd of June 2006. The relinquished sub-blocks are

shown on figures 1 & 2, and are listed as follows:

3.0 Geology

3.1 Regional Geology

The Charters Towers Goldfield lies along a regional scale geological structure, the

Mosgardies Shear Zone. Hutton (1994) has shown that this shear zone is a major crustal

block boundary separating two separate types of deep crustal rocks. Work by the

Australian Geological Survey Organisation (Shaw et al, 1996) has established that the

Mosgardies is part of a coincident E-W gravity and magnetic boundary over 300km long.

The deep crustal structures are believed to have acted as channelways for the ore fluids

from which the Devonian gold orebodies were deposited. This major regional structural

control explains the extent, continuity, and relatively uniform structural control of most ore

bearing fissures in the district.


GSQ regional geology (Hutton et. al. 1996), showing relinquished sub-blocks.

District geology was described by Hutton and Rienks (1997). The Ravenswood Batholith

dominates the current land surface; an Ordovician to mid-Devonian igneous complex

intruded into a Pre-Ordovician package of metamorphosed sediments and igneous rocks.

The Batholith is in turn cut by Permo-Carboniferous intrusives.

The first phase of development of the Ravenswood Batholith was intrusion of granites

commencing at 490Ma (Hutton and Rienks, 1997). A major phase of intrusive activity

continued until the mid Ordovician. A second phase, dominated by extensional granodiorites

and tonalitic intrusives occurred from the mid-Silurian to the mid-Devonian. Deformation,

which occurred from the mid-Ordovician to mid-Silurian, is typically represented in the older

granitoids by steeply dipping, east striking narrow mylonite zones.

Mafic intrusives within the Batholith range from Ordovician to Silurian. Typical examples are

the Stannett Ck Gabbro and the mafic complexes north of Black Jack. Aplite and minor


pegmatite dykes are widespread, and NE trending basaltic dyke swarms occur near

Charters Towers. The Silurian Millchester Creek Tonalite, an irregular NW trending

intrusion that occupies the central Charters Towers area, cuts the older units.

The Early Devonian Broughton River and Deane Granodiorites were intruded at around 406

- 410Ma. These intrusives are more radioactive than most in the region and are distinctly

zoned as observed on radiometric and aeromagnetic images. The zoning may possibly be

evidence of convection? &/or differentiating magma chambers.

Shortly after, at ca. 400Ma, the Charters Towers mineralisation occurred at the same time

as the Lolworth Igneous Complex was intruded to the west. The mineralisation is

predominantly quartz reef hosted pyrite - sphalerite - galena - gold. The gold mineralised

fissures and associated sericitic alteration post dates the granitic intrusives and cuts across

all the earlier units in the area.

The Charters Towers style gold bearing ore shoots were typically precipitated as fissure

hosted quartz veins in structurally controlled trap sites at considerable depth. Many of these

are along kilometre scale lode zones, predominantly within granitic host rocks. On a regional

scale, Charters Towers style mineralisation is known for over 60 km. along the east-west

trend from Mt Hope in the west, to east of the Hadleigh Castle mine (Hartley & Dash, 1993).

Later NNW trending faults of possibly Permo-Triassic age cut the whole sequence.

Remnants of lateritised early Tertiary fluvial sediments occur locally associated with

duricrust capped palaeo-land surfaces.

3.2 Tenement Geology

The western group of four relinquished sub-blocks (Figure 3) is underlain by Siluro-

Devonian granitoids consisting of the Powlathanga Tonalite (SDgp) and the Centauri

Granodiorite (SDgc) (Hutton et al, 1996). Both these units are locally mottled and leached

indicating deep weathering. Tertiary and Quaternary sediments cover much of the

granitoids, especially over the western two sub-blocks. The main units of the cover

sequence are as follows:

Qa & Qr: Quaternary sands, clays, gravels, soils & alluvium.

TQr: Tertiary sand, mud, gravel, ferricrete & residual

soils.

Ts: Quartzose Sandstone, Clayey sandstone, mudstone, conglomerate,

undifferentiated sediments (including the Southern Cross

Formation).

Td: Tertiary duricrust – indurated weathering profile.

Figure 3: GSQ Geology of the western group of 4 sub-blocks (Hutton et al, 1996)


The five sub-blocks of the eastern group (Figure 4) are underlain by Ordovician granitoids

(Ogh & Oso), and one local occurrence of Pre-Cambrian metamorphics (P€ct) (Hutton et

al, 1996). The various units are described as follows:

Oso: Ordovician La Villa Igneous Complex (gabbros, quartz diorites &

diorites). Ogh:Ordovician Hogsflesh Creek Granodiorite (locally granites occur).

P€ct: Pre-Cambrian Charters Towers Metamorphics.

One significant shear zone is traceable for 11 km in an ENE – WSW direction. This shear

cuts the two southeastern sub-blocks of the eastern group of 5 sub-blocks relinquished.

This shear zone is based on geophysical interpretation.

4.0 Exploration

Work on the nine relinquished sub-blocks included obtaining and reviewing past

exploration and mineral occurrence data, the evaluation of exploration potential, soil

geochemical sampling, and aeromagnetic and radiometric interpretation. Fieldwork was

only undertaken on road reserves.

4.1 Mineral Occurrence Evaluation

Hartley (1993) evaluated the mineral occurrences on the Charters Towers 1:100,000 sheet

for the Geological Survey of Qld in the late 1980s. This work was evaluated and highlighted

one mineral occurrence on the relinquished sub-blocks (Figure 4). This is an un-named

Au/Ag prospect (GSQ 292702) that is located on the southeast sub-block in the eastern

group of five sub-blocks (near the junction of Hogsflesh and Roberts Creeks).

Figure 5: Aeromagnetic data (RTP – 1999) covering part of the eastern 5 sub-blocks.


4.2 Aeromagnetic Interpretation

The Company undertook detailed low level aeromagnetic and radiometric survey of adjacent

tenements in 1999-2000 (UTS Geophysics, 2000). The survey extended into the northern

and western sections of the eastern group of five sub-blocks (Figure 5). The full results

were previously reported to the Department (Morrison et al., 2001).

The aeromagnetic image in figure 5 has been converted to “Reduced to Pole” format to

assist interpretation. The northern and western parts of the eastern group of five sub-blocks

are just inside the survey area. It is clear that a prominent NE-SW lineament would extend

through the western most sub-block, and a strong NW-SE lineament would cut the middle

sub-block. No mineralisation or alteration is recorded along these lineaments. The NE-SW

lineament appears to represent the hidden contact of the Charters Towers Metamorphics in

this location. The NW-SE lineament does not appear to represent a rock type contact, but

the stream drainages may indicate a significant fault structure. Over several kilometres to

the

CT2006- 10

NW, along the NW-SE lineament, there appears to be an alignment of several prospects

including: Bonnie Doon, Marquis of Lorne, Telegraph and the Union Lode.

4.3 Soil and Rock Chip Sampling

Several reconnaissance soil lines were put in along roads, and totalled 83 samples

(Appendix 1). The eastern group of five sub-blocks contains three soil lines for a total of 65

samples (Figure 6), while the western group of four sub-blocks has one soil line of 18

samples (Figure 7). The soil samples were unsieved apart from coarse fragments and

designed to include any quartz or gossanous lag material. They were taken from a depth of

about 20cm, and were analysed for gold, silver, copper, lead, zinc, arsenic, bismuth,

molybdenum, iron, and sulphur. None of the 83 samples contain significant gold, and only

occasional weak lead values (<100ppm) showed some anomalism in the soils. Details of

assaying methods, sampling procedures, and standard geological codes used are located in

Appendix 2.

One rock chip sample (203833) was collected from the relinquished sub-blocks. This

came from the eastern group of five sub-blocks, and was taken somewhere along

Woodchopper Road, north of Hogsflesh Creek, in sub-block “U” of Clermont block 100

(AMG co-ords: E429457 & N7772383). It is described as a sub-outcrop quartz vein

sample that appears to be hosted in the Ordovician La Villa Igneous Complex (Oso). The

assay returned the following results (in ppm): 1.42 Au; 1.0 Ag; 33 Cu; 311 Pb; 115 Zn; 19

As; 3 Mo; 40,500 Fe, & 265 S. Despite the anomalous gold value, there has been no

follow-up of this sample.

5.0 Conclusions

No economically significant mineral occurrences were identified on the

relinquished sub-blocks.

Interpretation of aeromagnetic and radiometric data assisted the structural

and geological understanding of the tenements.

6.0 Rehabilitation

Fieldwork on the relinquished sub-blocks did not involve any significant ground disturbance.

Therefore no rehabilitation is required. A report on compliance with the Environmental Code

of Practice is included as Appendix 3.

PROCEDURE – BEFORE FIELD SAMPLING

Before attempting to do any soil sampling, rock chipping, lag sampling or stream sediment work, ensure that all the correct access to land procedures have been followed and that the land you are going to sample on has been cleared and authorized by management. Refer to SOP 051 – Access to Land. Also refer to the Sampling Survey Protocols.

Make sure your location has been clearly marked on the Field Location Map and that you have sufficient communication with your Department head or representative.

PROCEDURE - ASSAY METHODS

Assay methods used obviously depend on what the results are to be used for. Refer to Assay and Standard Protocols. For routine work the assays should be performed by the current NATA certified assay contractor. Normally different assay contractors are used for drilling / resource estimation assays from those used for rock chip / soil / stream sediment work. Sample submission is undertaken as described in SOP 511 - Geological Data Entry.

Specialised analytical methods are used where appropriate. In particular screen fire assays are used where coarse gold is potentially present such as in pyritic and/or gossanous quartz samples. Where more precise multi-element assays are required, typically a four acid “near total” digestion is used, HF-HNO3-HClO4 acid digestion and HCl leach.

Routine multi-element ICP analyses using aqua regia digest are undertaken to assist definition of mineral zonation, to investigate any high sulphide areas, and to check sulphide content for future environmental waste characterisation. Lead, and to a lesser extent zinc assays are useful indicators of gold mineralisation.

For routine work the following procedures are followed and elements are assayed for:

Rock Chip & non-quartz-sulphide diamond core samples Sample preparation (jaw crush to -6mm, ring mill pulverise entire sample to 85% -75um), Assay for Au (50g fire assay, AAS finish; detection 0.01ppm), Assay for Ag, As, Cu, Pb, Zn, Bi, Mo, Fe, S (ICP-AES after high temperature perchloric-hydrochloric-nitric acid digest).

75um),Soil samples Sample preparation (dry, ring mill pulverise up to 1.5kg to 85% -

Assay for Au (50g aqua regia leach at <800, graphite furnace finish; detection 0.001 ppm),Assay for Ag, As, Cu, Pb, Zn, Bi, Mo, Fe, S (ICP-AES using an aliquot from the gold aqua regia digest; semi-quantitative results).

Exploration stream sediment samples Bulk leach extractable gold (2kg active 24 hr pH controlled caustic cyanide solution extraction; detection 1ppb).

CT2006- 23

PROCEDURE - QUALITY ASSURANCE, STANDARDS, DUPLICATES AND BLANK ASSAY SAMPLES

Quality Assurance and Control (QA/QC

QA/QC assay blanks, standards and evaluation is routinely undertaken by the NATA certified assay contractors used by the Company. These include regular checking of assay data for precision and accuracy using re-splits, repeats, blanks and standards. Such check assays should usually be in the ratio of 2 standards, 5 replicates and 1 reagent blank per 50 to 84 sample.

In addition to these, internal quality assurance and control methods are being developed based on the Assay and Standard Protocols. The results of the standard assays are to be reviewed on a batch-by-batch basis and, if sample numbers permit, on a monthly basis with charts of the results prepared. All samples returning an initial assay greater than 1 g/t Au with potential to be included in resource estimation should be re-assayed. Inter-laboratory comparisons are to be run periodically which indicate an assay precision of better than +/-15% of the mean. Duplicate samples should have a precision of +/-10%.

Standards

Standards are to be inserted into assay batches to maintain a record of the laboratories quality control and assay accuracy. Standards come in a range of assay values and appropriately valued standards should be used with accompanying samples. Where Au values of samples taken are expected to be low, an appropriate standard of a low Au value should be used and vice versa. For current assay standards refer to the Assay & Standard Protocols. Normally, standards are added after every 50th sample, or 1 standard per batch where a lesser number of samples is submitted.

Different sampling applications will dictate various methods of use of standards, however, as a guideline, use the recommendations below. For rock chips, underground face, stockpile and diamond drill sampling, use discretion when choosing the value of the standard to be included. Assess the sampled material and decide whether the assay results should be high or low in Au, then, attach the appropriate sample.

Soil sampling: 1 standard per batch Low Au valueRock Chip sampling: 1 standard per batch Low to high Au

valueStream Sediment sampling 1 standard per batch Low Au value(If BLEG standard available)

SOIL SAMPLING:

PROCEDURE:

Before sampling:

CT2006- 24

Organise sampling equipment (First Aid Kit, drinking water, pick and shovel, sample books and bags or Kraft envelopes, data entry sheets, sieves, polyweave sacks, maps and GPS etc.)

Upon arrival at a sample site, take note of the best location to take a sample, trying to avoid any soil that may have been disturbed by earthworks, transported by creek systems or affected by old workings or constructions. These are the most common causes of soil contamination.Note: Samples taken from such areas are not a true representation of the local geochemical environment and should be avoided (if possible) at all times.

Sampling:First establish the correct material to sample and any size fraction and weight requirements. When a suitable site is found, dig out roughly a half metre by half metre area down to approx ten centimetres deep. Discard this top layer taking care to get rid of any large rocks and vegetation from the hole. You should start to see a change in the soil colour at this depth. If not, scratch further down until you do and discard this soil also. Sometimes, the soil colour will not change, in black soil areas for example. Make note of circumstances such as this and use your own discretion e.g. don’t dig forever looking for a colour change.

Once the surface layer (A Horizon) has been scraped clear of the hole, continue digging down (into the B Horizon) until you have enough to fill the bag or kraft envelope to the required weight. Discard any large rocks and excess vegetation and then sieve off the correct size fraction if this is required. Fill the sample bag and tie it off. Refill the hole and tamp down. Place the sample into a polyweave sack pre written with the lab address and sample numbers. Approximately 25 kg of samples in each sack is sufficient weight.

On the sample description sheet note the sample number, it’s location from the GPS, soil colour and any other comments you feel need to be made. Once all details have been recorded, proceed to the next sample site and repeat the same process. If soiling along a road, look for any approaching traffic before pulling out.

ROCK CHIP SAMPLING:(Includes niche sampling specific rock types or mineralisation)

PROCEDURE:

Before sampling:Upon arrival at site, write down sample number, coordinates of sample and a description of the rock chip taken using the rock chip sampling sheets. Be sure to wear safety glasses and a long sleeve shirt and trousers when hitting any rocks.

Sampling:

When you have decided on the rock to be sampled, break off a specimen piece to take back to the office and write the corresponding sample number on it. This piece can be handy as a quick reference in case of any anomalous assays.

Break up enough pieces of rock to about 2 kg, or if there is not enough for this, gather what you can and put in sample bag. Never break rocks by hand. Never break rocks in your hand with the G-pick. Preferably hold the rock firmly to the ground with your foot when hitting it, as long as it is big enough to do so safely. Tie off sample bag and place into pre numbered and lab addressed polyweave sack. Only mark the sample site if requested by the geologist. Spray paint a small mark at the site with fluorescent paint if permitted.

CT2006- 28

STREAM SEDIMENT SAMPLING:

PROCEDURE:

Before sampling:

Stream sediment sampling is undertaken to gather indicative geochemical information from a wide area without using extensive and costly exploration techniques. Active streams will carry minerals washed down from surrounding higher ground and this give you a very broad and diluted idea of mineral occurrences in the area. Samples are generally only taken from smaller creek systems. Stream sediment sampling is usually a first pass exploration tool.

The most common causes of contamination of a stream are disturbance by earthworks, old workings, constructions (Buildings, Stock yards etc) and bridges or vehicle crossings. Where possible these sites should be avoided.

Upon arrival at site, take note of the best location in which to take your sample according to the geologist’s requests. Write down the sample number, coordinates of the sample and other data required as well as any other relevant information necessary e.g. width of creek, outcrop nearby etc.

Sampling:

Collect your sample by taking a small channel of active stream sediment across the creek bed, generally avoiding any trap sites and sieving into a gold pan or dish, making sure to extract any vegetation from the sample. Sieve sizes, sample weights and collection methods may vary. Tie off sample bag / packet and place into pre numbered polyweave sack or carton.
