8 DETAILS OF THE MINE MINE AREA: This mine lease (ML) area is located at Addepalli (V), Chillakur (M), SPSR Nellore District, A.P. The mine site extends over an area of acres. The Mining lease area is located at a distance of 1.10 km from Eedulavaripalem village. GEOLGOY AND EXPLORATION: TOPOGRAPHY: The physiography of the area is flat sand bearing terrain with scattered small bushes and scrubs. The height of the dunes existing in the area varies from M from the ground level. The dunes are very less in number, the area is almost flat with slant topography. The height increases towards west from eastern side. Regional Geology: The geology of the area is comprised of Nellore Schist belt covered by sand formed by huge cyclone effect and back water of Bay of Bengal. The sand is widely exposed into surface; rather than area is fully covered by sand everywhere. The sand migrates from place to place by air borne weathering in the form of dunes. In this area due to the influence of migration of sand deposit, the ditches and worked out pits will be filled with fresh sand slowly. The schist, sand and sandy soil incorporates the general regional geology of the mining lease applied area. The main geological sequence is as follows: Recents Silica Sand and Clay Nellore Schist Belt Allumina and Silica Rich Products Dharwars Schists, Phylite etc. 8

9 Archaeons Igneous Rocks Local/Area Geology: Local Geology and Lithology of the area is as follows: Silica Sand Fine Grade Sandy Soil Schists and Other Rocks Silica Sand 1 to 5.0 M Thick Sand with Sedimentation of Clayey Material Below 6 M (Not confirmed in any of the existing operating mines) The mining lease applied area is fully sandy in appearance throughout. Therefore the geological sequences are referred in general way. Details of Exploration: No other exploration is carried out in the area as the subject area is applied for grant of quarry lease. Exploration already carried out in the area No mining is carried out in the area as the subject area is applied for grant of mining lease. RESERVES: The reserves are calculated by drawing cross sections perpendicular to slope namely A-A1, B- B1, C-C1 & D-D1. Based on the working pits of the existing mining leases around the subject area, the influence of the pit upto RL 90 (below the ground level) duly considering 4 M from surface as Proved Deposit and 6 M below as Probable & Possible Resources so the entire resources are calculated. As the entire area is occupied by the single litho unit silica sand deposit with East- West trend with shallow dips (6 o ) towards North. The litho units show a conformable sequence with gradational transitions. Hence, cross sectional area method is adopted for estimation of 9

10 reserves with sectional influence of 50 M. The volume arrived from the cross sectional area is multiplied with the sectional influence and tonnage factor 2.5 MT for arriving the reserves. The calculation Silica Sand reserves are given below. Category of Deposit as per UNFC guidelines The thickness of the ore body is not uniform; it changes from place to place in strike direction. The quality of Silica Sand also changes from central zone to contact zones. The mineralization of Silica Sand is uniform in the entire applied area. The availability ore body is homogeneous. Geological parameters considered for Proved Category (G1) Geological Survey: A topographical survey with total station was carried out in the total applied area. The boundary pillars were demarcated in the mine. A topographical map is prepared in 1:50000 scale and all the surface features are shown. The Geological mapping was carried out based on the topographical survey. All the litho units with their attitudes are delineated on the map. With the above mapping conducted in this mining lease applied area. It is classified under G1 axis. Feasibility Axis Considered for Proved Category (F1) Geology: The Silica Sand is mineralized in a continuous vein form in NW-SE strike formed by the Marine Tidal action (Deposition). A continuous process in Geological Mapping also proved in surface pitting. Mining: The mining plan is specially designed with 1.5 meters bench height for proper recovery of Silica. The recovery of the Silica Sand from ROM is 98%. 10

11 Environment: There are no habitants within the area and hence no rehabilitation is required. The dump benches are properly designed. The mine is developed in such a way that it has no impact on surrounding lands is completely barricaded with green belt. Processing: No processing is required for Silica Sand. Infrastructure, constructions and services: Temporary office building, rest house for labor, drinking water and toilers will be developed in the mines. Costing Capital Cost The following capital investment is made towards mining machinery and other infrastructure Office & Infrastructure Rs. 5000/- Operating Cost/Ton Excavation of ROM (2.5 Tons/M 3 ) Rs. 85/- Handling Charges Rs. 125/- Salaries and Other Expenses/Ton Rs. 2/- Safety & Environment protection/ton Rs. 25/- Statutory Payments & Local issues/ton Rs. 5/- Royalty Rs. 175/- Total Production Cost Rs. 417/- Or Say Rs. 420/- Marketing: The average sale price of Silica Sand grade ore is Rs.600 to 700 per ton ROM. Economic Axis Considered for Proved Category (E1) Detailed Exploration: The detailed Exploration including geological survey, sand probing, and deep trenches, has indicated recoverable/saleable silica sand. Mining Report/Mining Plan/Working Mines The Mining plan is being prepared after detail study of exploration and proper design implemented as per guidelines of IBM. 11

12 Specific end use grades of reserves All the reserves assessed are above the cut off grade of above 99% Silica Sand. At present depth, the total ore extracted in the mine is economically consumed in the Glass Industry. Specific knowledge of Forest/Non-forest and Other land use data The applied mining lease area is Non-Forest, Waste Barren Govt. Land partly and a little bit Patta Land. Based on the detail study under EFG classification of UNFC, the reserves estimated will come under proved reserves of category IV. Proved Category: An evidence to the prevalence of the sand in the form of Blanket form of Deposit. The reserves are estimated afresh based on the direct evidences of mineralization clearly seen in the mine. Hence all the reserves estimated will come under Proved category. The reserves are estimated upto 90 M RL as the Silica Sand is proved upto 96 mt RL with Sand Probing. The details of section wise and category wise reserves are furnished in the table. Resources: The mineable available below 96 m will be considered as Sand resources, which have to be proved with deep probing.

17 FRESH WATER REQUIREMENT & WASTE WATER GENERATION S.No Description Fresh water Waste water Disposal 1 Domestic 2.8 KLD 2.24 KLD Septic tank followed by soak pit 2 Dust 3.0 KLD - suppression 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 excavation and transportation activities. 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: Dust rising due to transportation will be controlled by covering the trucks with cloth; dust extractors will also be employed. Regular water sprinkling at dust emanating sources viz., storage dumps 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. 17

18 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 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 ML area. The total water requirement will be 5.8 KLD which will be utilized from nearby bore well. The usage will be as follows: Domestic Use KLD Dust suppression 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. Noise Environment: There will be intermittent noise levels during excavation 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. 18

19 The noise generated is very much minimum as the Silica sand mining 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. Providing noise insulation/padding wherever practicable. 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.. Analysis of Proposal: Financial and Social Benefits will be provided to local people. The waste water after Treatment will be used for Development of Green Belt in the Mined area. SOLID WASTE No solid waste generated. SOCIO-ECONOMIC ENVIRONMENT This mining project will contribute in the development of economic status of the region and indirectly provide a platform for many businesses; both on small and big scale. The company management would give preference to local people through both direct and indirect employment. SAFETY AND ENVIRONMENT The proponent will provide all necessary provisions stipulated under the Factories Act. In addition a safety committee will be formed and manned by equal participants from Management and Workers. Personal protection equipment (PPE) will be issued to each worker. Other safety equipments shall be used according to the nature of job involved. 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. 19

20 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. 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 and 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 monitoring of various environmental parameters shall be carried out 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. PROJECT SCHEDULE AND COST ESTIMATES: The envisaged average annual production of TPA of Silica Sand The cost of the project: 80 Lakhs The annual cost estimated for Environmental Monitoring is Rs. 15 Lakhs 20

21 CONCLUSIONS The land that is going to be disturbed cannot be reclaimed during the lease period, as the Silica sand 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 minimum and kept below CPCB/MoEF/SPCB standard norms (Air, water, noise standard limits). 21
