Kuramite is a mineral of the stannite group. It is named after the Kochbulak Au-Ag-Te deposit locality in the Chatkal-Kuraminskii Mountains in Uzbekistan, where it was first discovered.^[1]

Kuramite occurs in gold-sulfide-quartz veins as inclusions in goldfieldite, as observed in the Kochbulak deposit in Uzbekistan. It may also occur as microscopic crystals.^[4]

Kuramite has also been found in the Arctic Ocean, Argentina, Chile, DR Congo, Greece, Hungary, Japan, United Kingdom, and USA.^[4]

Kuramite's hardness on the Mohs scale is 5, and it has a density of 4.56.^[2] It is an opaque steel grey color with a metallic luster and a metallic streak.

The chemical formula of Kuramite is Cu₃SnS₄ with common impurities being iron, zinc and indium (Fe, Zn, and In).^[4][3]

X-ray study of Kuramite was done using the powder method, in the mineralogical laboratory of IGEM, Academy of Sciences of the USSR, by G. V. Vasova (RKO-57.3, unfiltered FeK).^[1] Kuramite was found to relate to the stannite-kesterite group. The parameters of the unit cell are found to be a=5.445±0.005 Å, c=10.75±0.02 Å, c/a=1.972.
