Gold mine known since ancient times.
"The Hutti mine is probably one of the most ancient metal mines in the world, dating to the Pre-Ashokan period. The ancient miners worked down to depths between 35m and 190m. The later which was intersected in 640 ft. level workings of the main mine in the 1890s, being the deepest known ancient working in the world. Evidences from the bottom of the ancient workings indicate that mine excavations by ancients was achieved by means of fire-setting. The carbon dating test of the old timber recovered from the bottom of ancient mine workings indicated that the ancient mining activity was about 1,900 years old." (http://www.huttigold.co.in/hutti/index/history#)

The deposit occurs within the 65 km long Hutti-Maski greenstone belt consisting of Archaean metavolcanic rocks (amphibolite and meta-rhyolite).
Gold mineralization at Hutti is confined to a series of nine parallel N-S to NNW-SSE trending, steeply dipping shear zones, that are locally referred to as reefs. From west to east the name of these reefs are (i) Main, (ii) Prospect, (iii) Oakley’s, (iv) Middle, (v) Zone-I, (vi) Village, (vii) Strike Reef Hanging Wall, (viii) Strike Reef Foot Wall and (ix) New East Reef and is situated very close to the western contact of the schist belt with granite. Currently, the mining activity is in progress in Oakley’s, Middle, Zone-I, Village, Strike Reef respectively.
