Parkerite, a rare nickel bismuth sulphide has been identified from Rakha copper deposit of Singhbhum shear zone. The mineral is associated with chalcopyrite, pentlandite bismuthinite and native bismuth. EPMA indicated the composition to be Ni3.17. Bi2.06 S2. The mineral has low indentation hardness (VHN 119 Kg/mm2) and the reflectivity ranges from 41.0% (470 nm) to 49.0% (589 nm).
