The Mines and Minerals (Regulation and Development) Act, 1957 (MMDR Act, 1957) is the legal framework that governs the development and regulation of mines and minerals in India. Effective from 12.01.2015, the MMDR Amendment Act, 2015 amended the MMDR Act, 1957.
The key feature of the amendment was the inclusion of a provision for awarding mineral concessions through auctions, replacing the previous “first-come-first-served” method. The objective of this amendment was to enhance transparency and eliminate any discretionary powers in the granting of mineral concessions at all levels.
Additionally, the auction method guarantees the revenue generated from the auction mines accrued to the state government. The auction system incorporates two forms of concessions, namely mining leases (ML) and composite licenses (CL), which encompass prospecting licenses as well as mining leases.
