4 2. Introduction of the project/background information: i) Identification of the project & proponent Present project is for manganese mining at village Maharkund in Saoner Tehsil of Nagpur district. Deposits at the Maharkund were worked by some earlier lease holder on a very small scale and then abandoned. Project proponent: M/s VRHPL, Nagpur has been engaged in manganese mining operations and sale of ores like bauxite and manganese. VRHPL hold manganese leases at Kirnapur (23.67 ha), Saoner tehsil and at Kachurwahi-Wadegon (78.5 ha) ) villages in Ramtek tehsil. They own a bauxite lease (95.57 ha) in Kumbhwade in Rajapur taluka of Ratnagiri district. Maharkund lease period is 50 years. Lease letter is at Annexure 1. Project: Location: Lease measuring ha is non- forest revenue land. It can be reached from Nagpur via Khapa and village Badegaon. Site can be reached from Badegaon by a seasonal road. Site is 46 km from Nagpur. Nearest railway station is Khapa.

7 ii. Brief description of nature of the project: This project proposal is for manganese mining by mechanized open cast method at village Maharkund in Saoner tehsil. Mechanized mining without drilling and blasting has been proposed because the ore is friable and soft. Geological reserves are 193,000 tonnes. Manganese contents vary from to percent; iron 8.67 to per cent and silica from to per cent. This lease has been previously worked but not in the recent past i.e. not after Width of manganese ore body is 1-2 m. Open cast excavation will be in the existing pits. First bench of 6 m height in first year will be 72 m along the strike. Second bench will follow as per mining plan. O.B., ore, rejects generation in two years O.B. = m 3 Ore = T Mineral rejects = T Soil = Nil Ultimate depth of the pit will be 39 m below ground level (bgl). Ground water table varies between 10 and 20 m bgl. Water from the working pit will be pumped out to a seasonal nalla to the west. This drain which ultimately meets the Khera seasonal drain and Khera drain meets the Kanhan river.

8 Equipment like back hoe, loaders (0.9 m 3 bucket capacity), rock breakers will be procured. iii. Need for the project/importance to country Manganese is required in steel and ferro alloys industry. There are a number of units around Nagpur. Quality of ore at Maharkund deposits is acceptable to these and will meet the requirements of regional manufacturers. This part of Maharashtra is known for manganese deposits and which have been worked since long. iv. Demand & supply gap: As in iii above and marketability has been confirmed by project proponent. v. Import vs. indigenous production: Import of this ore will reduce and hence the cost of production will also reduce proportionately. vi. Export possibility: Proposed production tonnes in two years will be adequate for domestic consumption and export is not envisaged at this stage. vii. Domestic markets: Bhilai steel plant, ferro alloys unit in Kanhan and Chandrapur area are assured markets.

9 viii. Employment generation: Revival of mining at this site will generate direct and indirect employment to about 40 persons including 12 technical persons. 3. Project description: i) This is an independent project and is not linked with any other project ii) Location: Location of lease at Maharkund is shown in Figure 1. Project boundary with coordinates is shown in Figure 2.

Proposed infrastructure: i) There will be one office shed, rest room and roads during the operational phase.

19 ii) Residential area is not planned; hence social infrastructure like sewerage, garbage management, power supply to colony etc. will not be necessary. v) Drinking water, rest room will be part of office premises. 7. R & R R & R is not involved in this project since land is owned by the proponent. 8. Project schedule & cost estimates Project proponent is acquainted with requirements of mining. It is proposed to start mining after EC is granted. Mining will be carried out as per the approved mining scheme during the years Cost estimates Item Asset Rs. In lakhs (Office, rest shelter, store guard room, plant & machinery etc) Working capital margin Pre operative 2.50 MSEDCL charges 2.50 Fixtures 1.00

20 Cost of production per tonne of ore is likely to be Rs 4000/-. Selling price is dependent on market at a point of time and can be between Rs /- per tonne. 9. Analysis of proposal: Review of the mining scheme, study of prevailing demand for manganese ore shows that it will be possible to mine manganese without disturbing any of the prevailing constituents of environment. Drilling and blasting will not be required because ore is soft. The only activity will be of transportation of mined ore from site to the user industry. There are no sensitive receptors or eco systems. Discharge of mine pit water will ensure perennial flow in the local drain which can be used for agriculture.
