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