Detailed geophysical and geological investigations to identify copper lead and zinc mineralization around Ambaji, Banaskantha district are in progress.

ISR has initiated a project on imaging the shallow subsurface of the Kachchh district for delineation of ground water aquifers and fresh water-saline water interface.
