7 Regional Geology: The region of the subject area belongs to peninsular gneiss of Archean group. The regional area forms a part of granite green terrain of eastern part of Dharwar Craton. These green rocks are introduced by granitic rocks of grey, brown and black varieties. In this area the granite terrain comprises of banded/streaky gneiss ranging in composition from tonalite to granodiorite, magmatic Gneiss and granodiorite granite with compositional variation between granodiorite granite and alkali feldspar granite. Among these Gneissic granites and dykes are suitable for us in stone industry. Geological Era Geological unit Rock Type proterozic Closepet granite and its equivalent peninsular gneiss with older Granite Migmatites Granite variants Migmatites *gneisses and granites Archean Schistose rocks of green stone belts and its equivalents Local Geology The subject area belongs to hillock rising to a height of about 110 m with boulders from ground level. The black granite is exposed as a boulder rock in the centre portion with gentle slopes and boulders are covering on top portion. The lease area is mostly consists of big dolerite boulders on the surface all along the trend of east to west. In this lease area about 5 6 m thick material is containing small, medium size and uneven boulders with multiple fractures and joint zones. The ripple type and migmatite granite boulders are exposed with a height of 2 to 3 m from the surface itself. The size of the boulders varies from 3 to 4 M 3. The boulders area available on the top of the hillock and sheet rock may be available below the boulders. The boulders are of uniform texture black granite which are of 5x3x3 m size on the mound of the deposit and small boulders are 3x2x2 m size area moderately distributed on the slope of the QL applied area. QL applied area is yielding good deposit of black granite which shows uniform in grain size with widely spaced joints.

8 The commercial name of Black Granite of Yadamari is G-20 of Chittoor. The rock is essentially composed of Quartz, Orthoclase Feldspar and biotite. The rock is compact and moderately hard with less joints. Estimation of Geological Reserves: Reserves: Geological traverses in the quarry and the sandy resources in the vicinity of quarries facilitated to access the shape and size of the deposit in the area. It is highly elevated deposit rising up to 110 m above ground level within the quarry area. Method of Estimation of Reserves: The calculation of prospects, deposit of mine is done at every stage, right from preliminary to last stage of exploration and mining The present exposure of the boulders and sheet rock, and the observations made in the adjacent quarry the reserves of the area has been estimated by the following parameters. The Black Granite is formed as Vertical Dolerite dyke. So that the proved Zone is considered up to the benches formation in lowest width of QL applied area and basing on the field observations and similar type of rock formation recoveries it is anticipated that the present recovery factor may be considered up to 20% and it ay may vary depth in future.

The mining advances east wards. An area of 1497 M 2 will be excavated producing 3042 M 3 of Market Grade Granite. Second Year: The mining will be continue towards east of 1 st year workings RL 593 m to 581m covering an area of 1512 M 2 two benches of 6 m x 6 m height will be formed. The mining advances East wards. An area of 1512 M 2 will be excavated producing 3262 M 3 Market Grade Granite Third Year: During the third year mining will continue towards 2 nd year workings RL 600 m to 588 m covering an area of 1492 M 2 two benches of 6 m x 6 m height will be formed. The mining advances East wards. An area of 1492 M 2 will be excavated producing 3262 M 3 of Market Grade Granite. Fourth Year: During the Fourth year mining will continue towards east of 3 rd year workings RL 602 m to 590 m covering an area of 1488 M 2 two benches of 6 m x 6 m height will be formed. The mining advances East wards. An area of 1488 M 2 will be excavated producing 3181 M 3 of Market Grade Granite.

12 Fifth Year: During the fifth year mining will continue below 4 th year workings RL 600 m to 598 m covering an area of 1493 M 2 two benches of 6 m x 6 m height will be formed. The mining advances East wards. An area of 1493 M 2 will be excavated producing 3136 M 3 of Market Grade Granite. An area of 7482 M 2 will be excavated producing M 3 of Market Grade Granite PROJECT DESCRIPTION TYPE OF MINING The Black Granite in the quarry lease applied area is exposed on the surface with boulders. Hence, it is proposed to mine the Black Granite by opencast, semi mechanized methods, by developing the benches of 6 M height with 6 M width from the top of the hillock. The development of benches in the sheet rock will be 60 o safety slopes. Therefore, mining operations are to be carried out in this area in 2 stages. 1. Development 2. Production Stage 1 The removal of big size and under sized boulders will be cleared in the quarry lease applied area for the next five years by using excavator. The hard rock exposed will be subjected to drilling, blasting and splitting from mother rock. Stage-2: After removal of weathered and semi weathered rock under sized boulders. The quarrying will be followed in the form of linear cut method. This involves loosing of primary block from the mother rock. Hence primary cutting will be done by line drilling method where loose spaced parallel holes along straight line will be made. Line drilling method is used for separation of primary blocks. i. Once the free face is developed in working place the primary cuts are taken up over a maximum length of 10 mtrs to a width of 3 mtrs and to a depth of 6 mtrs depends upon the joints availability. These dimensions are confirmed as for filed studies. Primary block will be cut into secondary blocks by jack hammers drilling and wedge cutting and this block will be dislodged from in-situ position by an excavator.

13 ii. Line drilling method will be used for cutting the primary blocks which involves drilling and blasting. iii. The holes are charged with low explosive cartridge like gun powder and non delay detonators for smooth blasting. iv. The use of delay detonators causes fragmentation and cracks in the rocks. The non detonating cords are inserted into the holes and the holes are stemmed with muck and plugged at the mouth and fired. v. Thus the blocks will be separated from the mother rock which is pulled of from the face with cranes or shovel. EMPLOYMENT POTENTIAL: The human resources deployed are as follows: S.

14 MANAGEMENT OF OVER BURDEN Rate of yearly generation of waste during the plan period: 80% of the solid waste of rocks m 3 generated can be used for the development of the internal roads and dumped in Dump Yard in SE side of Q.L applied area. So the dumping site is proposed in SE side of the quarry applied area with an area of 4088 Sq.mts. South and east side of Dump Yard is proposed Retention wall and garland drain to avoid of waste of QL applied area. Generated waste will be used for road development and backfilling. Year Rock 80% (M 3 ) 1 st nd rd th th TOTAL AVERAGE ENVIRONMENTAL MANAGEMENT PLAN The Environmental Management Plan envisage for this Mining Project is described here under with a strong commitment to follow the best Environmental Practices to reduce the negative implication to make this Project a sustainable development endeavor. The management action plan aims at controlling pollution at the source level to the possible extent with the available and affordable technology followed by treatment measures before they are discharge. Air Environment and control measures: The proposed mining activity would result in the increase of suspended particulate matter due to fugitive dust resulting from mining operations and transportation activities. Water sprinkling will be adopted to suppress the dust generated. Dust emissions and particulate emissions mitigation measures will be through water spraying at all the sources of dust formation and these measures are further elaborated as follows:

15 Regular water sprinkling at dust emanating sources viz., and transportation through haulage roads, etc will be carried out. Regular grading of haul roads and service roads will be taken up to clear accumulation of loose material. Periodic maintenance of transport vehicles and equipment will be carried out to check emission levels. Greenbelt will be developed with avenue plantation all along the haulage roads and peripheral plantation all around the mine in order to control dust. Overloading of trucks will be avoided and carrying the ore/mineral in covered trucks will be taken-up to minimize pollution levels. Water will be sprayed on haul roads for minimization of resuspension of dust due to transportation. Water Pollution Management: No rivers and other perennial water courses flow through the ML area. However, during rains the water flows through the slopes of the ML area and across the mine lease boundary and joins a natural drainage. The rainwater that collects in the mine pit bottom during the rainy season will be utilized for water spraying on the haul roads and mining area. This water will also be used for the plantation in and around the Mine Lease area. The total water requirement will be 11.5 KLD which will be utilized from nearby bore well and treated water from septic tank. The usage will be as follows: Spraying/Sprinkling on dumps, haulage roads KLD. Wire saw cutting cooling water KLD Plantation KLD. Domestic Use KLD The following that flows in the core zone will be routed adequately through channels to avoid any erosion and contamination. The mine pit water collected due to rains will be utilized for water spraying on the haul roads and for watering plantation. The waste water generated from the domestic usage will be fed to septic tank followed by soak pit.

16 Noise Environment: There will be intermittent noise levels during blasting and while usage of jack hammer. The noise levels are expected to be below 75dB. This will however be for very short duration. No mining activities are planned during night time. A thick green belt will be developed to act as noise attenuator. The management plan for controlling noise pollution is envisaged as follows. The noise generated is very much minimum as the Black Granite quarries is majority of manual and minimum Vehicular Traffic. The machinery will be maintained properly to reduce the noise levels. The protective noise reducing gear like earmuffs, the company will provide earplugs. Proper maintenance of equipment. Machinery will be fitted with properly designed noise generating acoustic silencers. Providing noise insulation/padding wherever practicable. Proper maintenance and periodic lubrication of noise generating parts of the machines Provision of thick plantation in and around the mine is planned in order to reduce the noise and prevent it from reaching to surrounding habitation areas. SOLID WASTE MANAGEMENT 80% solid waste of rocks generated can be used for the development of the internal roads and dumped in Dump Yard in SE side of Q.L applied area. So the dumping site is proposed in SE side of the quarry applied area with an area of 4088 Sq.mts. South and east side of Dump Yard is proposed Retention wall and garland drain to avoid of waste of QL applied area. GREEN BELT DEVELOPMENT The development of greenbelt in the peripheral buffer zone of the mine lease area will be undertaken well before the starting of the mining activity. Green Belt has been recommended as one of the major component of Environmental Management Plan, which will improve ecology, environment and quality of the surrounding area.

17 Plantation will be done along the haulage roads and the unused area in the ML area will be developed with green cover. Suitable advice on this plantation activity will be consulted with the local Forest Department along with measures to ensure good survival rate. Concepts of Green Belt Development The concepts of Green Belt Plantation scheme are 1. Nature of Pollutants 2. Emission Levels 3. Maximum Impact zone CRITERIA FOR SELECTION OF SPECIES Species to be selected should fulfill the following specific requirements of the area - Availability of seed material - Tolerance to specific conditions or alternatively wide adapts ability to ecophysiological conditions. - Rapid growth - Capacity to endure water stress and climatic extremes after initial establishment - Differences in height, growth habits - Pleasing appearance - Providing shade - Ability of fixing atmospheric Nitrogen - Improving waste lands. DESIGN OF GREEN DEVELOPMENT The greenbelt shall be developed around the plant to act as a sink for pollutants, attenuation of noise levels and improvement in aesthetic quality of the plant. The following criteria shall be adopted in the design of greenbelt: 1. Generally fast growing trees should be planted as otherwise it will take many years for other types of trees to attain their full height. 2. Trees will be planted along the road side in such a way that there is no direct line of sight when viewed from appoint outside the foliage perimeter. 3. Trees growing up to 10 m or more in height with thick perennial foliage should be planted around the plant. 4. Sensitive species such as magnifier indica should be planted in patches along the entire greenbelt to work as an indicator of pollution.

18 5. Trees shall be planted staggeredly in each row (minimum three rows encircling the perimeter of the plant). 6. Tree trunk being free foliage up to a height of 2 to 3 m, it is advisable to grow shrubs in front of trees to give coverage to the open portion. 7. Greenbelt will be developed all around the plant area with a width of 10 m. 8. Greenbelt will be developed around the plant except wherever buildings and other structures. 9. Local Plant species will used for development of green belt. SOCIO-ECONOMIC ENVIRONMENT The main occupation of villagers is agriculture. The commencement of mining activity will benefit the locals both directly and indirectly. The direct beneficiations will be those who get employed in the mines as skilled and unskilled workers. The indirect beneficiaries will be those who open small business to sell goods required by the residents whose Per Capita income will be enhanced by the mining activity and thereby their purchasing power will be increased. In the long run a lot of social goods is expected in the comparatively backward area when the inhabitants will be able to sent their children to school. SAFETY AND ENVIRONMENT The proponent will provide all necessary provisions stipulated under the Factories Act and mines act. In addition a safety committee will be formed and manned by equal participants from Management and Workers. The management firmly believes in the concept of safety and environmentally sustainable growth. The authorities and staff are very much concern in Environment issues. The management is going to develop scientifically designed green belt around the premises to mitigate air and noise pollution impacts on the surroundings. The management proposed to monitor ambient air as per APPCB guidelines. All the employees are provided with personal protective equipment such as helmets, hand gloves, safety shoes, goggles and apron as per their place of work. The management will provide safety training to all employees periodically and regularly.

19 POST PROJECT ENVIRONMENTAL MONITORING PROGRAMME In order to maintain the environmental quality within the standards, regular monitoring of various environmental components is necessary. The mines manager will take care of Environmental Management activities with objectives as To implement control/mitigation measures To monitor this implementation process To determine and improve the efficiency of the implemented measures To identify any other unforeseen effect on environment not covered hereby. To inspect and maintain the plantation survival rate, regular cleaning drains, channels and water logged ponds and improve the drainage system and retaining walls over certain timelines. Regular training will be given to mine workers as per DGMS rules. Regular monitoring of various environmental parameters shall be carried out through third party to ascertain the following points: Status of air, noise, water, land pollution within the plant and in its vicinity; Generate data for predictive or corrective purpose in respect of pollution; and To assess and monitor environmental impacts periodically. The frequency of monitoring will be done as per norms. PROJECT SCHEDULE AND COST ESTIMATES: The envisaged maximum annual production of Black Granite in a year is estimated to be 3262 M 3. The cost of the project : 65.0 Lakhs EMP Cost : 6.5 Lakhs CONCLUSIONS The land that is going to be disturbed cannot be reclaimed during the lease period, as the Black Granite is persisting at further depth and it will take a very long time to exhaust. No measures are proposed for reclamation of the disturbed land during the next five years. There is no other significant negative impacts are anticipated as the involved mining activities are very small. All possible measures shall be adopted to control pollution emissions to the

20 minimum and kept below CPCB/MoEF/SPCB standard norms (Air, water, noise standard limits).
