The Mineral exploration and mining history of India is closely related to the establishment of the Geological Survey (GSI). Mineral resource assessment projects include Ferrous Minerals, Base Metal, Precious Metals & Minerals, Non-Ferrous and Strategic Minerals and Industrial & Fertilizer.
Lately, GSI has taken the important policy decision of extending its regional work to a detailed exploration stage in potential development areas, ensuring that comprehensively explored areas can be offered to the stakeholders for exploitation. GSI is using a range of Robertson Geo tools for its exploration projects including IP, Magnetic Susceptibility, Spectral Gamma, Resistivity, Density, Neutron, etc. It also has a logging depth deployment capability of over 1,800m. Recent projects have included the economic feasibility of potash mining in the Hanumangarh district of Rajasthan.
After preliminary exploration GSI has found potash reserves of 133 million tonnes in one area of the district. Another long-time Robertson Geo client ‘Mineral Exploration Corporation Limited’ (MECL) will now undertake a more detailed study of the reserves.
