GEOLOGICAL MAPPINGThe lithological contacts of Limestone were marked in detail on Surface Geological Plan videPlate No.IV.The entire Mining Lease area is fully outcrop with limestone and the mining lease area isdivided into 6 section lines along the West-East. Detailed traverses were made along and inbetween all the cross section lines laid in the area and litho units exposed in the field weremapped. The order of occurrence and the exposure of litho units is as following:

O.B. Soil with a thickness of 0.2 to 0.25mGrey Limestone

The attitudes viz. strike and dip observed in various litho units were recorded. The generalstrike of the limestone band is N-S. The beds generally dip towards E. During mapping workthe local variations in the strike direction have also been noticed and shown in the geologicalplan. Limestone constitutes the elevated portion, present ridge resulting from weatheringerosion and structural disturbance.

In consideration of the data collected from the outcrops and subsequent exploration ofsubsurface data obtained from drill holes, different litho units were delineated and plotted onplan.

OUTCROP SAMPLINGWhile geological mapping, samples were collected from outcrops particularly near lithologicalcontacts. Outcrop samples were collected along section lines and the above

12

samples were analysed for their TC, SiO2, Al2O3 etc. During the exploration 169 nos. ofoutcrop samples were collected and analyzed. Summary of analysis of outcrop samplesenclosed vide annexure – XIIA.

DRILLING

Previously the Gujarat Ambuja Cements Ltd (GACL) and MECL has carried outprospecting in the area. 4 bore holes drilled by GACL has been marked on the plan.

The Mentioned 4 Core bore holes (OBH-1 to OBH-4) were drilled at grid interval of398m.X398m during 1996. Now the entire area has been explored with 54 bore holeswith grid intervals of 199m X 199 m. However these 4 bore holes have been shown inthe geological Plan & Section vide Plate No.IV & V.

M/s. GACL 4 nos 182.50

Total: 4 nos 182.50_____

All the bore holes were drilled vertically to establish the depth persistence of limestone.The quantum of core drilling was decided based on various considerations viz.topography, attitude, disposition of litho units, structural complexity of the deposit,compositional variation etc., and studied the depth persistence of different limestonebands, quality variations, if any, its subsurface behaviour and also to decipher thegeological structure of the deposit .

The Budawada mine is opened on 01.02.2014. The notice of sinking of bore holes inForm ‘J’ submitted to IBM vide our Letter No.MCL/Mines/RBLM/262 dated 03.03.2014.The core drilling activities are being commenced on 23.02.2014.

Core Drilling

A total metreage of 3100 m was drilled in 54 boreholes as on 15.06.2014. Core drillingwas carried out at 199 m X 199 m grid pattern in such a way that boreholes could yieldmaximum sub-surface data over the largest possible extent of the deposit upto a depthof 50 m. Out of 54 bore holes 8 bore holes drilled upto a depth from 50 m to 100 mwith a grid interval of 398 m X 398 m to establish depth persistence of limestone.Core boreholes were drilled up to a maximum depth of 50.00 m to prove the existenceof the limestone deposit for the proposed scheme period considering at presenteconomical limit of 25 m R.L (40m form the ground level).

Total No. of Bore holes drilled : 54

Total meterage : 3100

Minimum depth drilled : 50 m

Maximum depth drilled : 100 m

CORE RECOVERY

In a deposit where limestone is intercalated with clay and other soft & friable deleteriousmaterials, achieving good recovery of core was a difficult task. However, to ensuremaximum recovery, appropriate measures were taken and results were satisfactory. Thecore recovery achieved in different limestone units is ranging from 80 % to 90%.SAMPLING

Logging and Sampling:

Core samples were collected and were systematically processed to yield a representativepowder for carrying out the chemical analysis. The length of core obtained for every onemeter was measured for calculating the core recovery percentage. The core is then splitlongitudinally and logged by examining its colour, grain size, texture, compactness andminerals present. One half of the core was packed in the GI core boxes. The other halfof the split core was grouped for every 1.5 m for carrying out the full analysis. Thegrouped half core was pulverized to about 10 mm size, coned and quartered to yield arepresentative sample of about 200 gms. This sample was further pulverized and passedthrough 100 mesh BSS sieve to obtain a representative powdered sample.

CHEMICAL ANALYSIS

All Core samples collected from bore holes were prepared for carbonate analysis areutilized in preparing composite samples. While compositing due care was taken to reflectchange in lithology, chemical characteristics, core recovery & bench level etc. Thesecomposited samples were further pulverized and made to pass through 120 mesh BSSsieve and were analyzed for major oxides like SiO2, Al2O3, Fe2O3 CaO, MgO & LOI. Inaddition composite samples representing different depths are analyzed for alkalies (Na2O& K2O) and Minor constituents (SO3 and Cl-).

6. Geo-statisticalanalysis ofborehole data

In the area, borehole data shows that the characteristic featurein the deposit is the occurrence of clay pockets within thelimestone. Though, generally the limestone is hard andcompact in nature the top of limestone column exhibitsfrequent joints and fractures. These joints and fractures actas channels for the movement of the ground water as well aspercolation of surface water runoff resulting in the formation ofcavities of large dimensions.

Based on the above detailed assessment code 1 is awarded on Geological axis.

Based on the surface and subsurfaceborehole data incorporated the proposed working pit andultimate pit limits etc are framed.




Limestone deposit is outcropped in the most of explored area.Extension and existence of Limestone is well established bydetailed drilling in the entire Mining Lease. Hence Geo-physicalsurvey is not required.


The total Mining Lease area consists of 160.00 hectares.

1) A total metreage of 3100 m was drilled in 54 boreholes.Core drilling was carried out at 199X199m grid pattern in sucha way that boreholes could yield maximum sub-surface dataover the largest possible extent of the deposit.

Total 54 no. of Core boreholes were drilled, out of which 8 no.of holes drilled upto a depth of 100 m to assess the depthpersistence of limestone and remaining 46 holes drilled up to adepth of 50 m.

In this method of drilling core collected and analyzed in orderto recover the core.

The entire area is explored with a grid interval of 199m X 199m upto a depth of 50 m. Hence the reserves upto a depth of50 categorised under G1 category.

The area under G1 level of exploration is demarcated in theGeological Plan (Plate No.IV) and Geological cross sections(Plate No.V).

34

Core samples were collected for every 1.5 mts interval.Prepared and analysed for all radicals. Litho-chemical logs(Form-K) of these samples recorded at Annexure- XIIB.


Limestone in the area is massive fine grained grey, whitelimestone, argillaceous limestone / shale. The Limestone showtypical bedded nature with varying thickness. The action ofground water on these limestone has resulted in the formationof solution cavities at different places.

6. Geo-statisticalanalysis ofborehole data

In the area, borehole data shows that the characteristic featurein the deposit is the occurrence of clay pockets within thelimestone. Though, generally the limestone is hard andcompact in nature the top of limestone column exhibitsfrequent joints and fractures. These joints and fractures act aschannels for the movement of the ground water as well aspercolation of surface water runoff resulting in the formation ofcavities of large dimensions.

The ensuing five yeardetailed programme should but be a part of the conceptual overall mining plan.

(i) Period of anticipated life of the mine:

The mining operations will be continued for a further period of 36 years after this Schemeof Mining i.e., up to 2054-2055. The residual reserves will be 88.96 million tonnes at theend of this scheme period. The rate of production will be 2.5 million tonne per annum.Based on this rate, the life of the mine will be about 36 years after completion of thisscheme period.

The ultimate pit limit is assumed on the present production/requirement keeping in viewof present economic feasibility. A water reservoir will be maintained in part of the minedout area. The Limestone is existing upto a depth of about 90 m and during this schemeperiod the deepest workings will be 33 m RL (32m depth from surface RL). Hence nobackfilling is proposed during this scheme period. This will be reviewed during nextscheme period.

The Ammonium Nitrate storage room is in our Jayanthipuram Limestone mine. TheANFO mixing shed is also is in the same place. The Ammonium Nitrate is mixed with FuelOil in the licensed premises and the same is transported to this mine by Explosive van.The License copies of ANFO and explosive van are enclosed vide Annexure – XIV & XV.

5.2 Yearly pit-wise development plan proposed for the next five years, depictedon plans and sections (ore and overburden to be shown clearly along withgeological formations encountered depicting also the design and layout of themine benches in case of opencast mining).

Mechanised opencast method of mining using heavy earth moving machinery with deephole drilling and blasting. It is proposed to mine the limestone with 8 m benches fromtop 65 m RL to bottom 33 m RL (i.e., 32 m below ground level) during this schemeperiod. The entire area is explored and based on the bore hole data the area year wiseproduction and development proposed.

The benches will be advanced towards West, East, North and South side of the MiningLease. A quantity of 12,500,000 M.T. of Limestone and a quantity of 1,54,652 Cu.M ofwaste development are proposed respectively during this scheme period. The waste willbe accommodated in the Temporary dump yard located at South West Corner of themining lease. The dump is chosen in the South West corner of the lease area because theentire mining lease area is forest and non mineral bearing area is not available fordumping of waste. The mining will not be taken up during this scheme period in theproposed temporary dump yard. The temporary dump yard will not block the reserves asthe generated quantity of waste will be used for road formation, plantation etc in future.

The detailed exploration has been carried out and established a total resources of 175.24million tonnes of limestone. Keeping in view of the resources available in other captivemining lease areas of our Jayanthipuram Plant, it is reviewed and proposed to produceabout 2.5 million tonnes of limestone per year from this subject mine for the overallsystematic development of the deposits, mineral conservation and life of the mines.

The year-wise production and development proposed after establishing the mineablereserves (111) under G1 scale of exploration.

45

The year-wise Production, development and direction of advances of the face is furnishedin the following table.

There is no overburden. The waste is interstitial clay only. The waste proposed in theabove may not be generated and the interstitial clay if any may get mixed with the ROMand transported along with production. The benches will advance towards North, South,West and East. The general ground level of Limestone is 65 m R.L. The advancement ofproduction is towards North, South, West and East. The location and direction ofmovement of faces year wise is shown in plate no. VI-A to VI-E.

The proposed production may vary based on the captive consumption of the cementplant, Cement market conditions, and production from other captive limestone minesbased on the quality. However the production will not cross the above proposal.

The installed Clinker capacity of the cement plant is 2.8 million tonnes for which thelimestone requirement is around 4.2 million tonnes. To meet the Limestone requirementof plant, it is proposed to produce about 2.5 million tonnes of limestone from this mineand remaining quantity will be met from other captive mines. However the productionquantities may vary based on the marketing conditions and the quality of limestoneproduced from other captive mines but will not exceed the proposed quantities duringthis scheme period on yearly basis.

Local Geology Of The Area:

The limestone deposit forms a part of Nargi Limestone belonging of Kurnool System.The entire area of 160 hectares is mostly covered with limestone outcrops, with verylittle soil cover in between outcrops.

As observed from outcrops of limestone, the general strike of the limestone band is N-Sand dip is towards W-E. In some areas the beds dipping 2° to 5° towards SE due to localvariations.

It is a simple deposit. The detailed description of litho units is given below:

Cement grade LimestoneThe average quality of grey limestone is as under:

SiO2 Al2O3 Fe2O3 CaO MgO LOI

% % % % % %Core Quality 13.0 1.3 0.5 46.1 0.6 37.1

Limestone deposit within the ML area forms part of Proterozoic Palnad sub-basinequivalent of Narji limestone formation of Kurnool Super Group. These carbonate rockswere formed by sedimentary origin. The bedding in Limestone is generally residual andhas not often been totally obliterated and dips exhibited by the rocks are those of theshear planes or secondary cleavage. Solution cavities are existing. The topography isundulating with surface reduced levels varying from 60m above MSL to a maximumelevation of 74m. The area is characterised by sparse vegetation like thorny bushesetc.,The deposit is simple and general strike of the beds varies from North-South anddipping towards East direction. Lithological sequence of the area from top to bottom isLimestone and shale.

The deposit is simple stratified tabular deposit of regular habit under categorized – I asper UNFC norms.

2.2 Reserves :

Category wise (proved, probable and possible) reserves estimated in the earlier MiningPlan/Scheme of Mining with grade:In the approved mining plan 91.10 Million tonnes of total mineral resource shown underthe category of 122.

2.3 Mining method:

Mechanised opencast method of mining using heavy earth moving machinery with deephole drilling and blasting. It is proposed to mine the limestone with 8 m benches fromtop 65 m RL to bottom 33 m RL (i.e., 32 m bgl) during this scheme period. The entirearea is explored and based on the bore hole data year wise production and developmentproposed.

The benches will be advanced towards West, East, North and South side of the MiningLease. A quantity of 1,25,00,000 M.T. of Limestone and a quantity of 1,54,652 Cu.m ofdevelopment are proposed respectively during this scheme period. The waste will beaccommodated in the dump yard located at South West Corner of the mining lease. Thedump is chosen in the South West corner of the lease area because the entire mininglease area is forest and mineral bearing and no area is available for dumping of waste.The mining will not be taken up in this dump proposed area during this scheme periodwhich will take lot of time. The dump yard will not block the reserves as the generatedquantity of waste will be used for road formation, plantation etc in future.

The year-wise production and development proposed after establishing the mineablereserves (111) under G1 scale of exploration.

The year-wise Production, development and direction of advances of the face is furnishedin the following table.

There is no overburden. The waste is interstitial clay only. The waste proposed in theabove may not be generated and the interstitial clay if any may get mixed with the ROMand transported along with production. The benches will advance towards North, South,West and East. The general ground level of Limestone is 65 m R.L. The advancement ofproduction is towards North, South, West and East.

Risk assessment is a continuous process whereby risks are analyzed, assessed and riskmanagement priorities are evaluated.

Objectives of risk assessment:

Identifying hazardous activitiesassessment of risk level and severity in different operationsidentification of control measuressetting monitoring processreduce the impact of mishaps of all kindsreduce the inherent potential for major accidents

Methodology of Risk assessment:Collection of information & identification of hazardClassify their severity and probability of occurrenceIdentification of exposed risksAssess the risk and risk rating based onProbabilityExposureConsequencesPrioritization of the risksImplementation of control measuresMonitoring risk assessmentEvaluation and correction

Risk assessment is mainly based on the environmental impact of various parameters.

i) Land contamination:-The potential for contamination during operation of mine site is, waste rock dump whichregard as contaminated land.

ii) Aquatic toxicity:-

The risk assessment in aquatic toxicity system is based on the total metal concentrationin various chemical form or oxidation state. Limestone does not contain appreciableconcentration of toxic elements.

79

iii) Acid mine drainage:-

The mining of limestone does not involve any processing operation by using chemicals.Hence there is no risk at mine site with regard to control of acid mine drainage

iv) Tailing dam:-

Tailings are very fine residuals in the chemical processing operation. It is a potentialsource of environment contamination. In the limestone mining operation there is nopossibility of tailing materials since it is not involved in the chemical process.

v) Human health:-

The chemicals from tailing dam and waste heaps may severely affect the human health.The sulphur contained in the dump can make the land toxic which indirectly affect thehuman health. During Environment Impact Assessment toxicity is nil. Hence there is norisk involved to human health due to limestone mining operation.

Factors of risks involved due to human induced activities in connection with miningoperations are 1) removal of O.B and side burden 2) drilling 3) blasting 4) excavation ofore and 5) transportation of ore.

Other factors due to natural activities are 1) fire 2) water inundation 3) electricity and 4)natural calamities.
