The Geological Survey of India (GSI) is conducting advanced G2-level exploration for rare earth elements (REE) in West Bengal's Purulia district and Assam’s Karbi Anglong. GSI Director General Asit Saha stated that both blocks are likely to be auction-ready within a year, marking a key step in tapping India’s strategic mineral reserves.

Speaking at the 3rd Minerals and Mining Conclave 2025 organised by ASSOCHAM, Mr Saha noted that while specific rare earth elements are yet to be confirmed, the deposits may include a "basket of 14 to 17" REEs. This diversity could pose technical challenges during extraction. Additionally, vanadium reserves have been identified in the lower Himalayan belt, expanding the country’s critical mineral portfolio.

G2-level exploration refers to an advanced stage of geological investigation, involving sampling to assess the quality and quantity of mineralisation. Upon completion, the findings will be submitted to the respective State mining departments and the Union Ministry of Mines for further action.

The exploration drive comes amid rising demand for REEs in electric vehicles, electronics, defence systems, and medical technologies. The move aligns with India’s broader goal of strengthening self-reliance in high-tech manufacturing and e-mobility.
