BHUBANESWAR:Under the National Airborne Geophysical Mapping Programme, the Geological Survey of India is conducting advanced Heliborne TDEM and Magnetic Surveys across 10 mineral potential zones in Rajasthan, Odisha, Karnataka, Andhra Pradesh, and Telangana.
The surveys aim to identify deep-seated and concealed mineral deposits, including critical minerals vital for India’s energy transition and strategic sectors. In 2025–26, data acquisition has been completed in 1 block of Rajasthan, 2 blocks of Odisha, and 3 blocks spanning Karnataka and Andhra Pradesh, with work currently underway in Raichur district, Karnataka.
Using state-of-the-art multi-sensor TDEM and magnetic technology, the programme enables high-resolution subsurface mapping and detection of conductive mineral zones at depth. Upon completion, the datasets will be made publicly available through the National Geoscience Data Repository, supporting government and private agencies in advancing scientific mineral exploration and resource development.
