Mineral exploration and mining history of India are closely related to the establishment of Geological Survey of India (GSI). Mineral resource assessment projects include Ferrous Minerals, Base metal, Precious Metals & Minerals, Non-Ferrous and Strategic Minerals and Industrial & Fertilizer Minerals. Mineral prognostication through synthesis of multithematic data forms a critical component of natural resource assessment studies. Lately, GSI has taken an important policy decision of extending its regional exploration work to detail exploration stage in the potential exploration blocks so that comprehensively explored blocks can be offered to the stakeholders for exploitation.
