Book's First Pagea two tier system providing self-evaluation templates to be filled in by the mine operator followed by validation through Indian Bureau of Mines. Mining Surveillance System To curb on menace of illegal mining, a satellite-based monitoring system namely Mining Surveillance System (MSS), was developed and launched which aims to establish a regime of responsive mineral administration through automatic remote sensing detection technology. The latest satellite image is juxtaposed on geo-referenced mining lease maps to check any illegal mining in the vicinity. Mineral Resources The classification of reserves/resources of various minerals based on United Nations Framework Classification (UNFC) was done in April 2010 following which National Mineral Inventory was prepared. The UNFC consists of a three dimensional system with three axes- economic viability; feasibility assessment; and geological assessment. Bauxite Total resources of bauxite as per UNFC in the country are placed at 3,897 million tonnes. These resources include 656 million tonnes reserves and 3,240 million tonnes remaining resources. By grades, about 81 per cent resources are of metallurgical grade. The resources of refractory and chemical grades are limited and together account for about 5 per cent. Odisha alone accounts for 51 per cent of country’s resources of bauxite followed by Andhra Pradesh (16 per cent), Gujarat (9 per cent), Jharkhand (6 per cent), Maharashtra (5 per cent) and Chhattisgarh and Madhya Pradesh (4 per cent each). Major bauxite resources are concentrated in the east coast of Odisha and Andhra Pradesh. Chromite As per UNFC system, total resources of chromite in the country as in 2015 are estimated at 344 million tonnes, comprising 102 million tonnes reserves (30 per cent) and 242 million tonnes remaining resources (70 per cent). About 96 per cent resources of chromite are located in Odisha, mostly in the Sukinda valley in Jajpur and Keonjhar districts. Minor deposits are scattered over Manipur, Nagaland, Karnataka, Jharkhand, Maharashtra, Tamil Nadu and Andhra Pradesh and Telangana. Gradewise, charge-chrome grade accounts for 31 per cent resources followed by ferrochrome grade (18 per cent), beneficiable grade (25 per cent) and refractory grade 14 per cent. Low, others, unclassified and not known grades together account for 13 per cent. Copper The total resources of copper ore in the country as in 2015 are estimated at 1511.50 million tonnes with about 12.16 million tonnes of copper metal. Of these 207.77 million tonnes (13.74 per cent) fall under Reserve category containing 2.73 million tonnes of copper metal and the balance 1303.73 million tonnes (86.26 per cent) are ‘Remaining Resources’ containing 9.42 million tonnes of copper metal. Rajasthan is credited with 813.33 million tonnes ore (54 per cent) containing 4.48 million tonnes of copper metal, Madhya Pradesh 283.43 million tonnes ore (19 per cent), containing 3.42 million tonnes copper, Jharkhand, 295.39 million tonnes ore (20 per cent), containing 3.28 million tonnes of copper metal and the rest 7 per cent are accounted
