1.5.0 REVIEW OF IMPORTANT CHAPTERS OF PREVIOUS PLAN

1.5.1 EXPLORATION: State Geology and Mining Department have already carried out detailed mapping of the Mineral deposits in these areas during 1992 to 1993 by regionally. The Geological Survey of India has already carried out detailed mapping of the commercial Quartz & feldspar deposits of Tamilnadu. In the previous approved scheme period, two boreholes with each 10m depth was proposed, but the lessee has carried out six boreholes upto 9m depth during the previous scheme period. There is one existing pit and their dimension is given below.

Locations of drilled boreholes are marked in the geological plan and sections and year wise plan and sections (Refer Plate No.IV & V).

Scheme of Quarrying Avadathur Quartz and Feldspar Quarry The quarry has reached maximum 30m depth and based on the existing pit and drilled boreholes, the depth of the mineralization has been proved upto 30m depth with an average of 2m topsoil. The lease area is narrow and irregular; therefore the bench formation below 32m depth in the southwest and below 23m depth in the Northeast from the elevated portion of the lease area would be difficult. Hence, the reserves and resources are estimated as given below during the present scheme period.

Table-4 Depth of estimation of the reserves and resources during the present scheme period [2015-16 to 2018-19]

32m [2m topsoil + 6m Overburden + 24m pegmatite (Quartz + Feldspar)] From the elevated portion of the lease area

Eight boreholes upto 20m depth are proposed during the present scheme period in the year 2015-16 at 50 grid interval, to know the characteristics features of pegmatite vein and to find out the further depth persistence of the mineralization. No trial pits and trenches are proposed during the present scheme period. Locations of proposed boreholes are marked in the geological plan and sections and year wise plan and sections (Refer Plate No.IV & V). 1.5.2 MINE DEVELOPMENT: During the time of previous approved scheme period (2010-11 to 2014-15), one year 2010-11 is lapsed. Proposals were given only for four years 2011-12 to 2014-15 and the mining operation was proposed to be carried out in the southern portion of the lease area in northeast-southwest direction to a depth of only 8m. The mining operation was carried out in the South and Southeastern portion of the lease area. At present there is one existing pit and its dimensions is 240m (max) x 47m (max) x 30m (d) (max).

Handling of waste and ore & Places of working: The wastes include mineral rejects, topsoil. The mineral rejects is 40% of ROM which includes rock fragments, impurities etc. The mineral rejects generated during the previous scheme period was dumped in the northwestern portion of the lease area. The topsoil generated during the previous scheme period was utilized for afforestation purposes.

1.5.3 EXPLOITATION: In the approved Scheme period (2010-11 to 2014-15), the planned production of Quartz & Feldspar was about 1531 tonnes @ 60% recovery, whereas the actual production of Quartz & Feldspar during the second scheme period was about 2810 tonnes @ 60% recovery. The production and development was carried out in the South and Southeastern portion of the quarry lease area.

1.5.4 RESERVES ESTIMATED IN THE EARLIER APPROVED SCHEME PERIOD [2010-11 to 2014-15] WITH GRADE.

During the previous approved mining scheme period (2010-11 to 2014-15), the reserves were estimated upto 32m depth with an average of 2.0m topsoil.

The grade of the Quartz & Feldspar mineral is of glass and ceramic grade. The bulk density of the mineral was taken as 2.6. Table-6 Reserves estimated in the earlier approved scheme period [2010-11 to 2014-15]

Total Mineable reserves as per the previous approved Scheme period (2010-11 to 2014-15) @60% recovery = 99,979 Ts Reserves depleted during the previous approved Scheme period (2010-11 to 2014-15) @ 60% recovery = 8,810 Ts

Scheme of Quarrying Avadathur Quartz and Feldspar Quarry The reason for deviation in production of ROM: Production during the previous plan period was higher than the anticipated and the reason was due to good market demand. Pegmatite consists of Quartz & Feldspar conglomerate together. The recovery percentage of the quartz & feldspar is based on the total recovery. During the operation on the band, it is found that the enrichment of feldspar and quartz varying. Depending upon the market demand, the lessee will exploit the mineral. Hence, the deviation in quartz & feldspar is bound to occur.

1.6.0 AFFORESTATION PROGRAMME: During the previous plan period, it was proposed to plant 15 neem saplings covering an area of 150 sq.m with 60% survival rate every year in the southern boundary barrier of the mining lease area. Afforestation was carried out and the survival rate of the plants was below 25%, due to poor rainfall.

1.7.0 RECLAMATION AND REHABILITATION: Reclamation and rehabilitation was not proposed during the previous scheme period, and hence neither reclamation nor rehabilitation was carried out during the previous scheme period. The reclamation and rehabilitation will be carried out only when the quarry reaches its ultimate pit limit. The mineral rejects generated during the previous scheme period was dumped in the northwestern portion of the lease area. The topsoil generated during the previous scheme period was utilized for afforestation purposes. At present the quarry attained a maximum depth of 30m from the elevated portion of the lease area and the quarry has not reached ultimate pit limit, hence backfilling program has not been commenced. 1.8.0 CONTROL OF DUST, NOISE AND VIBRATION: The air in the area is quite fresh, quarry operation was carried out manually and jackhammer, tractor mounted compressors are deployed for the development activities. The shot hole with shallow depth performed for hard strata in relation to wind direction. Hence, the dust was minimal well within the prescribed limits. Anyhow the Ambient quality of Air respect of dust concentration, repairable dust,

SO2, NO2 were tested periodically for every season around 1 kms radius for core and buffer zones as per the guidance of TNPCB. The dust prone areas of the quarry are Blasting site, Loading, Hauling and dumping. All such areas were closely monitored as per the guidelines.

Scheme of Quarrying Avadathur Quartz and Feldspar Quarry 1.9.0 NOISE & GROUND VIBRATION: The quarrying operations do not produce any adverse environmental impacts. The quarry operations involve with minimum shot hole drilling, having 1.5 meter depth, and controlled blasting technique adopted with low VOD of class 2 slurry explosives. Hence, the noise & vibration is minimum, below the norms as prescribed in the MMR, 1961 and their amendments. The operational area lies away from the human settlement. No ground vibration noticed in and around the lease area during the course of quarrying operations.

1.10.0 SIGNIFICANT FEATURES: Being the company is much concerned above the environment, the company closely monitored the environmental factors systematically without degrading the land, water and air. However, tests have to be carried out to show the actual performance of quarry on environmental issues which will be complied in the present Scheme period.

Scheme of Quarrying Avadathur Quartz and Feldspar Quarry 3.3 DETAILS OF EXPLORATION: a. Geological Mapping (Topographical and Contour map in 1: 1000 Scale) The area was surveyed in detail by total station survey instrument with micro station software to prepare a geological map in the scale of 1:1000 showing the various formations, attitude of the deposits and the reserve position.

b. Geo-physical prospecting in the way of vertical electrical sounding. Geophysical survey in the form of vertical electrical sounding (VES), was conducted in the lease area to assess the lateral variations, vertical in homogeneities and the sub surface geology with respect to the availability of resources and reserves of Quartz & Feldspar deposits. c. Geo-chemical prospecting. The lessee collected samples from the existing quarry pit and drilled boreholes for NABL laboratory for testing and analysis to find out the chemical and physical properties of the Quartz & Feldspar mineral. It was inferred that the grade of Quartz and Feldspar is found to be of glass and ceramic grade and the recovery percentage of Quartz and Feldspar mineral is 60% and the bulk density is 2.6.

d.Technological prospecting.

Pitting: Since the Quarry is active and the depth of the quarry has already reached about maximum depth of 30m, there is no additional formation of pits in the existing quarry. The quarrying pit indicates the pegmatite vein deposit and direction of the vein. Besides, eight boreholes are proposed to be carried out during the present scheme period in the year 2015-16 at 50m grid interval and the samples will be analyzed.

Trenching As discussed above, there is no requirement of trenching in the existing quarry. Besides, in and around active quarries of the lease area proves the terrain consist of quartz & feldspar deposit.

Drilling The quarry has been in operation for more than a decade. The quarry has reached maximum 30m depth in the pegmatite vein. To conform the characteristics features of pegmatite vein and to find out the further depth persistence of the mineralization, eight boreholes upto 20m depth, are proposed during the present scheme period in the year 2015-16. No trail pit and trenches are proposed during the present scheme period.

Locations of proposed boreholes are clearly marked in the Geological Plan & Year wise plan (Plate No. IV & V).

3.3.1. PROPOSED STUDY TO BE CARRIED OUT: The reserves were estimated upto 32m depth during the previous scheme period.

Total Mineable reserves as per the approved scheme period (2010-11 to 2014-15) @ 60% recovery = 99,979 Ts Reserves depleted during the scheme period (2010-11 to 2014-15) (Quartz & Feldspar) = 8,810 Ts The existing pit has reached a depth of 30m. During this scheme period, the reserves are calculated upto 32m [2m topsoil + 6m Overburden + 24m pegmatite (quartz + Feldspar)] and the resource and reserves are reassessed on 08.06.2016. The informations gathered from the excavated pit are correlated to discuss the pre feasibility studies and to calculate the resource and reserves. During the present scheme period (2015-16 to 2018-19) the quarry operation is proposed to be carried out by opencast method with 3m bench height and 5m bench width to a depth of 32m [2m topsoil + 6m Overburden + 24m pegmatite (quartz + Feldspar)] from RL 302.0m to RL 270.0m.

3.4 METHOD OF ESTIMATION OF RESERVES: The quarry lease area is a slightly elevated topography and the quarrying operations were carried out for more than a decade. Based on the information gathered from the excavated pit, the depth of mineralization, petrographical settings of the area, geology of the formation, commercial utilization of mineral and the cut off grade has been ascertained clearly. By the experience gained by the lessee during the past years, the parameters required for the calculation of resource and reserves are reassessed afresh on 08.06.2016 for 32m depth with an average of 2m topsoil. The grade of Quartz & Feldspar inferred was found to be of glass and ceramic grade and this has been reconfirmed by carrying out analytical studies in NABL laboratory. The lease area is narrow and irregular; therefore the bench formation below 32m depth in the southwest and below 23m depth in the North east from the elevated portion of the lease area would be difficult. Hence, the reserves and resources are estimated as given below during the present scheme period.

Scheme of Quarrying Avadathur Quartz and Feldspar Quarry Table-14 Depth of estimation of the reserves and resources during the present scheme period [2015-16 to 2018-19]

32m [2m topsoil + 6m Overburden + 24m pegmatite (Quartz + Feldspar)] From the elevated portion of the lease area

Eight boreholes upto 20m depth are proposed during the present scheme period in the year 2015-16 at 50 grid interval, to know the characteristics features of pegmatite vein and to find out the further depth persistence of the mineralization. No trial pits and trenches are proposed during the present scheme period. Locations of proposed boreholes are marked in the geological plan and sections and year wise plan and sections (Refer Plate No.IV & V). The estimation of mineral reserves is done by cross sections method. For Reserve calculation the length and width of the deposit is shown in the Geological plan & cross sections. (Please Ref. IV & V). The recovery percentage of Quartz and Feldspar in this quarry is 60% which is well inferred by the experience gained by the lessee during the previous quarrying activity and also by the field tests carried out in the lease area and analysis done in NABL Laboratories. The bulk density has been reckoned as 2.6.

As analyzed by NABL laboratories Quartz, which has more than 95% SiO2 and

Feldspar, which has more than 18% Al2O3 and more than 12% of K2O, is best suited for Industrial grade. The geological plan demarcating the commercially viable quartz and feldspar body has been prepared in 1:1000 scale (Plate No. IV). Totally three sections have been drawn, one along the strike direction as (X-Y) Length wise and other two sections are Perpendicular to strike as (A-B & C-D) Width wise which is suitably chosen to cover the maximum area, in the scale of Horizontal 1:1000 & Vertical 1: 500 respectively. (Plate No. IV). The details of estimation of geological resources and mineable reserves with reference to the geological plan & cross section and Conceptual Plan & Section as shown in (Plate No.IV & IX).

The Geological resources computed based on the geological cross sections up to the economically workable depth of 32m depth from the elevated portion of the lease area at the rate of 60% recovery (quartz 10% + feldspar 90%) yields 3,83,184 Ts and 6,38,641 Ts of ROM. The total geological resources are computed as 32m depth for economically viable at present market scenario. Mineable reserves have been computed as 1,12,933 Ts at the rate of 60% recovery (quartz 10% + feldspar 90%) and 1,88,222 Ts of ROM up to a depth of 32m. The mineable reserves are calculated by deducting the mineral locked up area under safety distance and bench loss. Hence the remaining area is taken for calculation of mineable reserves up to 32m depth (Refer plate No.IV).

4.0 MINING: 4.1 SALIENT DESCRIPTION OF THE PRESENT MINING METHODS: The mining operation is proposed to be carried out by opencast method. Jackhammer, tractor mounted compressors are deployed for the development activities. The pit geometry is designed according to the operating conditions of machinery. The drilling hole is carried out with jackhammer, of small diameter (30-32 mm) at shallow depth and blasted with class 2 slurry explosives with charge ratio as 0.7 to 0.9. Manual labours will be engaged for jackhammer drilling, sorting of waste and for loading the quartz and feldspar into trucks. The initiation system is done with controlled blasting techniques under the supervisation of competent persons.

Drilling Source:- Jackhammer operated by the compressed air from Tractor mounted compressor or Portable compressors.

Drilling parameters:- Burden 0.9m spacing 1.0m depth 1.65m

Charge pattern:- Charge ratio 0.7 to 0.9 kgs per hole. Stemming is 1/3 and explosives 2/3. The stemming material is moisture clay/pyroxenite mixed waste. 19

Scheme of Quarrying Avadathur Quartz and Feldspar Quarry Initiation System:- Bottom initiation system with safety fuses and ordinary or /plain electric detonators. No of blast hole: Number of the hole required per day is 7, based on the above said parameters. The dimension of the benches is proposed at 3m height and 5m width for the easy movement of men and machinery during quarry activities. The slope of the benches is maintained at 60o and less for the safety factors of the machines and men working inside the quarry. There is one existing pit and its dimensions are 240m (max) x 47m (max) x 30m (d) (max). The top soil is of 1m thickness, one bench is formed with 2m height with 450 slope. There will be ten benches in mineral with 3m height, 5m width and slope maintained as 600 from horizontal. The advancement of the pit will be from the Northeastern side of the quarry lease area and progress towards Southwest of the lease area upto 17m [2m top soil + 6m Overburden + 9m Quartz & Feldspar (Pegmatite)] from RL 302.0m to RL 285.0m during the present scheme period. During the present scheme period, the quarry operations are proposed to be carried out in the first, second, third, fourth, fifth and sixth benches. The mineral rejects and over burden that would be generated during the present scheme period is proposed to be dumped over the existing waste dump situated in the northwestern boundary barrier and also proposed to be dumped in the Southeastern boundary barrier of the lease area. Topsoil that would be generated during the present scheme period is proposed to be dumped in the Northeast and southwestern boundary barrier of the lease area and will be utilized for afforestation purposes. Proper footpath will be made between the benches for the easy access of face workers to carry out the ROM from the quarry. The waste is proposed to be handled manually or occasionally by tippers for dumping on the southeast and southwestern side to the lease area. Afforestation is proposed in the Eastern side of the 10m boundary barrier. If there is any considerable increase or decrease in the recovery factor a modified scheme will be prepared and submitted to relevant authorities for subsequent clearance and approval.

4.3 PROPOSED RATE OF PRODUCTION WHEN THE QUARRY IS FULLY DEVELOPED: The proposed rate of production where the quarry is fully developed is 9,827 Ts per annum at the rate of 60% recovery. The production schedule for this plan period are drawn mainly in consideration of reserves position, market demand, men, machinery development and the cost of production. The entire mined Quartz & Feldspar is completely sold in domestic market. The viability may vary, since the market of Quartz & Feldspar depends upon the grade and requirement of industrial grade, which are governed by the market demand. The economic viability at present market conditions are tabulated below: Table -20 S.No Particulars Cost of production Per tonne 1. Labour charges Rs. 300 2. Royalty paid to Mines & Geology Rs.83 3. Explosives expenses Rs.123 4. Drilling expenses Rs. 264 5. Transport from mine head to Stockyard (loading Rs.270 & unloading) Total Rs.1040 6. Miscellaneous over needs Rs.300 Total Rs.1340 7. Average Sale value of the quartz and Rs. 1600 feldspar for commercial grade

The cost of production is Rs. 1340/ton and selling prize for Quartz & Feldspar is

Rs.1600/ton. Hence, the quarry is economically viable at present market conditions.

Scheme of Quarrying Avadathur Quartz and Feldspar Quarry 4.4 MINEABLE RESERVES AND ANTICIPATED LIFE OF QUARRY: Available mineable reserves reassessed as on 08.06.2016

Total Mineable Reserves ROM = 1,88,222 tonnes Proposed annual production ROM = 33,729 tonnes Anticipated life of the quarry = 1,88,222 / 33,729 = 6.0 years

An optimum depth of 32m has been established as economically viable depth for the safe and scientific quarrying. The Mineable Reserves are calculated by excluding the quarry loss due to formation of benches with suitable height & width, ultimate depth of quarry, the

Mineral Reserve held up within the safety distances all along the lease boundary.

The Mineable Reserves @60% for this Quartz and Feldspar quarry is thus arrived as

1,12,933 Ts and ROM 1,88,222 Ts for an assumed depth of 32m from the elevated portion of the lease area.

The average production of Quartz and Feldspar from this quarry is 20,237 Ts per year

(10% Quartz + 90% Feldspar) and Mineable recoverable reserves 1,12,933 Ts considering at the rate of 60% recovery (Quartz & Feldspar) for the entire life of the quarry.

Based on the above, and taking into consideration of the available Mineable reserves, the life of quarry will be about 6.0 years (considering 32meters depth at present scenario) at 60% recovery (Quartz & Feldspar), if the quarry is being worked continuously with an average annual production of 20,237 Ts (10% Quartz + 90% Feldspar). The life of the quarry may extend after carrying out the detailed exploration which is likely to be carrying out during the year 2015-16. The Exact life will be discussed in the ensuing scheme. This calculation is based on the plan approved by Director of Mines Safety leaving Benches and Safety barriers.

4.5 EXTENT OF MECHANIZATION: The following machineries are utilized on rental basis for the development and production work at this quarry.

The above machineries are adequate to meet out the simultaneous development and production schedule drawn out in this plan of quarrying.

5.0 CONCEPUTAL MINING PLAN: (REASSESSED) Salient features of an updated/modified conceptual plan of the quarry covering the period of anticipated life of the quarry, depicted on quarry geological plans and sections with necessary statement annexed supported by essential text, covering the basic & long term design features of quarry covering exploration, quarry development, optimum exploitation & utilization of the mineral, waste & sub-grade mineral management, and environmental aspects. The ensuing five year detailed programme should but be a part of the conceptual overall scheme.

5.1 TIME FRAME OF COMPLETION OF MINERAL EXPLORATIONS PROGRAMME IN LEASE HOLD AREAS: Detailed exploration including geological mapping, geophysical prospecting, geochemical prospecting and technological prospecting and periodical sampling has been carried out by lessee and consulting Geological Team to establish the Mineral Reserves and resources. The production and development for the present scheme is discussed upto a depth of 17m [2m topsoil + 6m Overburden + 9m pegmatite (quartz + feldspar)] in north and western portion of the lease area. To conform the characteristics features of pegmatite vein and to find out the depth persistence of the mineralization, eight boreholes upto 20m depth are proposed during the present scheme period in the year 2015-16. No trenches and trail pits are proposed during the present scheme period.

5.2 ANTICIPATED LIFE OF THE QUARRY: Available mineable reserves reassessed as on 08.06.2016 Total Mineable Reserves ROM = 1,88,222 tonnes Proposed annual production ROM = 33,729 tonnes Anticipated life of the quarry = 1,88,222 / 33,729 = 6 years

Scheme of Quarrying Avadathur Quartz and Feldspar Quarry Based on the above, and taking into consideration of the available Mineable reserves, the life of quarry will be about 6 years (considering 32meters depth at present scenario) at 60% recovery (Quartz & Feldspar), if the quarry is being worked continuously with an average annual production of 20,237 Ts (10% Quartz + 90% Feldspar). The life of the quarry may extend after carrying out the detailed exploration which is likely to be carrying out during the year 2015-16. The Exact life will be discussed in the ensuing scheme. This calculation is based on the plan approved by Director of Mines Safety leaving Benches and Safety barriers.

5.3 GEOLOGICAL PLANS AND SECTIONS: The quarry lease area is a hornblende biotite gneisses form of the oldest rock formation in which pegmatite intrusion lies over. On regional scale the pegmatite vein trends N400E- S400W with Vertical dip. Geological plan and sections in the scale of 1:1000 was prepared based on the surface plan (which was carried out with help of total station survey 1:500 scale) to attribute all the geological parameters. Please refer plate No. IV for geological plan and sections. The ultimate pit dimensions are as under: (Depth from the elevated portion of the lease area) Table – 23 Size of pit after four Ultimate pit dimensions at the Dimensions Present size of pit years end of life of the quarry Length (m) 240 (max) 244 (max) 244 (max) Width (m) 47 (max) 81 (max) 81 (max) Depth (m) 30 (max) 30 (max) 32 (max) Please refer Plate No. IX.

5.3 EXPLORATION, MINE DEVELOPMENT:

State Geology and Mining Department have already carried out detailed mapping of the Mineral deposits in these areas during 1992 to 1993 by regionally. The Geological Survey of India has already carried out detailed mapping of the commercial Quartz & feldspar deposits of Tamilnadu. In the previous approved scheme period, two boreholes with each 10m depth was proposed, but the lessee has carried out six boreholes upto 9m depth during the previous scheme period. There is one existing pit and their dimension is given below. Existing Pit Geometry: Table-24 Length Width Depth Area Dip˚ Strike In Meter In Meter In Meter In Ha. 240 (max) 47 (max) 30 (max) 1.12.8 Vertical N400E- S400W

With the datas analyzed from the existing pit and drilled boreholes, the deposit has been proved upto 30m depth with an average of 2m topsoil. The borehole logging datas are furnished below.

Locations of drilled boreholes are marked in the geological plan and sections and year wise plan and sections (Refer Plate No.IV & V).

The lessee with his consultant geological team thoroughly studied the area and demarcated the attitude of the band. It is inferred that the Quartz & Feldspar mineral is of glass and ceramic grade and in form of band running from N400E- S400W direction with Vertical Dip. Regular sampling and analysis during the past mining activities has revealed that the Quartz and Feldspar mineral is of ceramic and glass grade. The recovery of 60% was discussed in the previous approved scheme period and the same 60% recovery was achieved during the previous scheme period. During the course of quarry operation the ratio of feldspar mineral is enhanced from 80% to 90%. Hence the same 60% recovery with ratio of quartz and feldspar - 10%: 90% is discussed during the present scheme period. The quarry has reached maximum 30m depth and based on the existing pit and drilled boreholes, the depth of the mineralization has been proved upto 30m depth with an average of 2m topsoil. The lease area is narrow and irregular; therefore the bench formation below 32m depth in the southwest and below 23m depth in the Northeastern side from the elevated portion of the lease area would be difficult. Hence, the reserves and resources are estimated as given below during the present scheme period.

32m [2m topsoil + 6m Overburden + 24m pegmatite (Quartz + Feldspar)] From the elevated portion of the lease area

During the present scheme period (2015-16 to 2018-19) the quarry operation is proposed to be carried out by opencast method with 3m bench height and 5m bench width to a depth of 32m [2m topsoil + 6m Overburden + 24m pegmatite (quartz + Feldspar)] from RL 302.0m to RL 270.0m.

5.4 OPTIMUM EXPLOITATION & UTILIZATION OF THE MINERAL: The quarry lease area consists of 2.36.5 Ha, after leaving 7.5m & 10m boundary barrier, only 1.83.5Ha could be mined. Out of this only 0.85.5 Ha is proposed for an optimum depth of maximum 17m [2m top soil + 15m Quartz & Feldspar (pegmatite)] from RL 302.0m to RL 270.0m has been taken into consideration for the utilization of the mineral in the present plan period, keeping in the view of mineral conservation, preservation and development. Anticipating the market demand, this present quantity of exploitation is proposed during the present scheme period.

Available mineable reserves reassessed as on 08.06.2016 Total Mineable Reserves ROM = 1,88,222 tonnes Proposed annual production ROM = 33,729 tonnes Anticipated life of the quarry = 1,88,222 / 33,729 = 6 years

Scheme of Quarrying Avadathur Quartz and Feldspar Quarry 5.5 WASTE & SUB-GRADE MINERAL MANAGEMENT: The anticipated waste during the present plan period is about 98,813 tonnes (40% mineral reject + Over burden). The mineral rejects and over burden that would be generated during the present scheme period is proposed to be dumped over the existing waste dump situated in the northwestern boundary barrier and also proposed to be dumped in the Southeastern boundary barrier of the lease area. Topsoil that would be generated during the present scheme period is proposed to be dumped in the Northeast and southwestern side of the lease area and will be utilized for afforestation purposes. This aspect has considered and accordingly Conceptual Mining Plan is drawn. This waste will be dumped separately in steps to prevent erosion and sliding. Retaining wall will be constructed around the dumps.

Proposed backfilling Southwest 45mx35mx32m (h) (sloping)

There is no proposal for backfilling the mined out area in this scheme period. Backfilling will be carried out at the end of the life of the quarry when the quarry reaches its ultimate pit limit. There is no sub grade mineral in the quarry. The waste does not consists any toxic substance in the form of solid, liquid and gas. The waste is only the contamination of secondary minerals in the Quartz & Feldspar mineral, which cannot be separated. If the mineral reject does not fill the quarried out pits completely, the left out pits will be fenced for collection of water which will be utilized for maintaining the afforestation all along the lease boundaries, besides the collection of rain water will also enrich the water table in and around the area.

5.6 ENVIRONMENTAL ASPECTS: The mining operation is proposed to be carried out by opencast method. Jackhammer, tractor mounted compressors are deployed for the development activities to win the mineral, minimum drilling & blasting for the quarrying activities. Manual labours will be engaged for jackhammer drilling, sorting of waste and for loading the quartz and feldspar into trucks Hence, the impact on environment like noise, dust, vibration, air pollution, water pollution may be minimal and well within the prescribed standards.

5.7 PRESENT MINING LAND USE ENVISAGED: After complete exploitation of Pegmatite (Quartz & Feldspar) to economic limit, the pit will be partially backfilled and partially allowed to stagnate the rain and seepage water, and act as sump of that area. The dewatering will be made by means of oil engine or LT electric power source; the same will be utilized for afforestation purpose and to enhance recharge the agricultural wells nearby.
