Mohite: Properties and Occurrences

Mohite is a copper-tin sulfide mineral with the chemical formula Cu2SnS3. It is a triclinic-pedial greenish-gray mineral containing copper, sulfur, and tin. It is of hydrothermal origin and occurs associated with tetrahedrite, famatinite, kuramite, mawsonite, and emplectite in the type locality in Uzbekistan. It has also been reported from Salamanca Province, Spain; the Organullo Mining District of Salta Province, Argentina; and the Delamar Mountains of Lincoln County, Nevada, US.
