'''Hemusite''' (IMA symbol: Hm) is a very rare isometric gray mineral containing copper, molybdenum, sulfur, and tin with chemical formula Cu<sub>6</sub>SnMoS<sub>8</sub>.<ref name=terziev />

==Discovery and occurrence== It was discovered by Bulgarian mineralogist Georgi Ivanov Terziev in 1963. He also described it and named it after Haemus, the ancient name of Stara planina (Balkan) mountains in Europe. The type locality is Chelopech copper ore deposit, Bulgaria.<ref name="mindat" /> Later tiny deposits of hemusite were found in Ozernovskoe deposit, Kamchatka, Russia; Kawazu mine, Rendaiji, Shimoda city, Chūbu region, Honshu Island, Japan; Iriki mine, Iriki, Satsuma-gun, Kagoshima Prefecture, Kyushu Region, Japan; Kochbulak deposit, Tashkent, Uzbekistan.<ref>{{cite web |url= http://www.mineralatlas.eu/lexikon/index.php/MineralDataShow?mineralid=1562&sections=12 |title= Information about Hemusite |publisher= Mineralienatlas Lexicon}}</ref> Hemusite occurs as rounded isometric grains and aggregates usually about 0.05&nbsp;mm in diameter and in association with enargite, luzonite, colusite, stannoidite, renierite, tennantite, chalcopyrite, pyrite, and other minerals.
