Mineral Exploration Corporation Limited (MECL) is functioning under Ministry of Mines, Govt. of India with 100% Government of India holding, for systematic exploration of minerals “To Bridge The Gap Between Initial Discovery of Mineral Prospect and its Eventual Exploitation”. It is the only organisation both in Government and in private sector, possessing entire spectrum of mineral exploration facilities under one roof . Since its inception in 1972, MECL has grown from strength to strength by adopting modern techniques of exploration and it has now emerged as the premier exploration agency in the country. The Company has its corporate office at Nagpur, Maharashtra, with a number of Zonal / Project offices located throughout the length and breadth of the country. The authorised capital is Rs. 125 crores.
Dedicated service of MECL in mineral exploration over three decades has resulted in updating mineral inventory of various minerals manifold and setting up of a number of mineral based industries and Companies in India. Since inception till date, it has completed over 1331 projects of detailed mineral exploration, mine development and 1,56,665 million tonnes of mineral reserves have been established. The exploration inputs are 9.47 million metres of drilling, 3.32 million metres of geophysical logging, 6126 sq.km. of detailed geological mapping and topographical survey and 0.29 million metres of exploratory & developmental mining. Beside this more than 186 projects on remote sensing and environmental studies have also been completed.
The main strength of the company is its team of well-qualified and experienced exploration geologists, geophysicists, analytical chemists, drilling & mining engineers and surveyors supported by highly skilled, trained technical and scientific staff and state-of-art computer facilities.
MECL has made noteworthy contributions in development of the nation by exploration of coal, lignite, base metals, gold, bauxite, limestone etc. and has achieved several distinctions such as ;
Brought India on the world bauxite map by augmenting large metallurgical grade bauxite reserves in East Coast Provinces of India, which was appreciated by World class Players in aluminium industry. This has resulted in creation of National Aluminium Company Ltd. (NALCO), the largest aluminium Company and several investments are in pipeline for greenfield alumina/aluminium plants.
The largest open cast mine for copper at Malanjkhand and rich copper potential of Banwas had turned out to be the lifeline for Hindustan Copper Ltd. (HCL).
