3.0 Geological Reserves The reserves are computed basing on the available sub-surface Lithology of the subject area and also excavations made in the existing quarries adjacent to the subject area by other lease holders. It reveals that the sheet rock is encountered right from the surface and it extended further depths. However, thickness available upto 110m level is taken for computation of proved deposit and 10m each below the proved as probable and possible deposit. The proved deposit is considered as "Reserves" and the probable & possible deposit is considered as "Resources". Further, the percentage of recovery is a major parameter in arriving mineable deposit. In this area the 25% of recovery is considered leaving remaining percentage as waste which includes soil, bands of weather rock, fault rock, joint cracks etc. Section wise calculation of black granite reserves are given in the following table.

Total Reserves of Colour Granite @ 25 % recovery = 685418 m3 The reserves are blocked by the 7.5 barrier zone (622m x = 6988 m3 45m (average thickness) x 25% recovery factor) From pit slopes, the reserves blocked are calculated @ = 700 m3 10% of the reserves blocked in buffer zone Total Non-mineable reserves = 6988 + 7000 = 7698 m3 Total reserves assessed - Non-mineable reserves = 685418- 7698 = 677720 m3 4.0 Mineable reserves and life of the mine Total mineable reserves of 677720 m3 are available in this QL area. The production is proposed to obtain 9000 m3 per year. At this rate of production, the expected life of the mine is calculated as below. Life of the quarry: Mineable reserves/annual production = 677720 m3/9000 m3 = 75.30 years or say 75 years. 5.0 Mining Method The mining operations are carried out by opencast semi mechanization method by developing multiple benches of 5-6 m height. To minimize the cost of production and to achieve annual target production. The quarrying operation are planned to carry out partly manually and partly deploying machinery. 5.1 Separation of Large Primary Blocks of Mother Rock The primary cuts i.e. the lateral and horizontal cuts by diamond wire saw cuts through slaughter holes (A 50 m wire saw run gets around 600m2 Cut) and if situation permits by use

A-5 L. Srinivas Annexure of Form-1 of detonating cords a close spaced blast is performed (To leverage natural Joint). 10 m in length and 8 m in width and 6 m height Sizes are produced. The wire for Granite is made of the steel wire, sintered beds with plastics injected on the steel wire and between diamond beds in order to safeguard the steel wire from the abrasive components of granite (i.e Quartz, Feldspar, etc). The stationary diamond wire machines were born for three main purposes:  Squaring and dressing of irregularly shaped blocks, preparing them for final processing in slabs and tiles.  Making thickness of stone of certain width in order to utilize the best gang saws and blocks cutter having maximum productions and profit from the processing machines.  Perform automatic cuts of block into slabs of different thickness. The block can so be programmed to have a certain number of slabs each of prescribed thickness. 5.2 Sub Division of Large Primary Block Into Secondary Block (secondary Cuts) 1. Once the primary blocks are dislodged from sheet rock depending up on the dislodged material secondary blocks are cut, fractures, block lines and penetrative cracks are carefully trimmed and removed by this way. 2. The commercial blocks will be trimmed so as that the sites form right angles to each other 3. The size of blocks could be formed from the ROM of this property will be in the following dimensional ranges. Gang saw sizes Cutter sizes Length : 190 to 380 cm 90 to 180 cm Width : 140 to 200 cm 60 to 90 cm Height : 120 to 170 cm 40 to 70 cm Production of commercial blocks To give a regular shape, the removed blocks are dressed with cutting and polishing face, and the other direction perpendicular to it. For this purpose also Jack Hammer drills and feather wedges are widely used. Below sizes were produced in the ratio of 1:3 and also depending upon the recovery.

ANNEXURE - II Drilling and Blasting Drilling and blasting plays vital role in determining the size and shape of rough blocks. Drilling Pattern is important in developing a working face and also preparing the rough blocks suitable for their use in appropriate processing units. There are no important places in and around the area, blasting will be carried with precautionary measures. Drilling Parameters i. Drill holes diameter: 74/Pmm ii. Depth and inclination of the blast holes: 3 meter in case of separation primary blocks depending on the block size. Then the drill-hole will be vertical. iii. Burden and Spacing: 1.5m X 3 m iv. Stemming and charging of the blast hole: The blast hole will be charged with 100 grams of explosives and filled with clan pills subsequently; the shot hole will be stemmed using brass stemming rods. v. Explosive type: (1) Slurry based explosives or Gun Powder. Broad Blasting parameter Drill-Hole patterns for primary and secondary smooth blasting. Uniform single line equidistant holes (line drilling) will be deployed for separation of blocks from mother rock. In the case of sheet rock the primary drilling will be in the form of equidistant vertical holes to take out blocks of Gang Saw.

ANNEXURE – IV Solid Wastes Generation and Management Plan It is proposed to produce around 42683 m3 marketable granite in five years. Considering a recovery factor of 25%, to win possible 42683 m3 of granite blocks, it will be necessary to handle approximately 171450 m3 granite. Thus, 75% of waste amounting to 128588m3 will be generated over a period of five years. Such kind of waste will be dumped in dumping yard. Most of the solid waste will be disposed for road construction, back filling of mine excavation and some other general purpose. Solid waste generated year wise for first five years plan as below Table A-6. Table A-6 Solid waste generated year wise
