Vulcanite is a rare copper telluride mineral. The mineral has a metallic luster, and is a green or bronze-yellow shade. It has a hardness between 1 and 2 on the Mohs scale (between talc and gypsum). Its crystal structure is orthorhombic.
It is named after the place where it was discovered in 1961, the Mammoth Good Hope Mine in Vulcan (ghost town and district), Gunnison County, Colorado, US. Small deposits have also been discovered in Japan, Russia, Saudi Arabia, and Norway. It occurs with native tellurium, rickardite, petzite and sylvanite.
