For the first time gold deposit has been located in Rajasthan in the Aravallis. The gold mineralisation is associated with minerals such as pyrite, pyrrhotite, arsenopyrite and chalcopyrite. Host rock is found to be carbonate dominated volcano-sedimentary rock. Detailed exploration has been carried out in 4 blocks -Bhukia, Jogpura, Dughocha Main and Dugocha North and Dughocha east and following deposits have been proved. Dughocha Main Block: 0.48 million tones with 2.24 ppm Au Dughocha North Block : 0.24 million tones with 1.91 ppm Au Dughocha East Block: 0.1 million tones with 2.00 ppm Au. This significant prospecting breakthrough has jumpstarted exploratory studies for similar type of deposits in other schist belts of Rajasthan. While prospecting for gold in Dugocha area a unique rock akin to Shungite of Keralia, Russia has been identified. Compositionally, it has been identified as metaexhalite.
