Vulcanite

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 Moh's scale (between talc and gypsum). Its crystal structure is orthorhombic.

It is named after the locality where it was discovered, the Good Hope Mine in Vulcan, Gunnison County, Colorado, USA. Small deposits have also been discovered in Japan, Russia, Saudi Arabia, and Norway. It occurs with native tellurium, rickardite, petzite and sylvanite.
