Sierra Nevada Mine, Comstock Lode, Virginia City, Comstock Mining District, Storey County, Nevada, USA

Piece of stockwork vein material. Thin quartz veins (probably with adularia) are evident. In these veins, sparse sulfides are present, including pyrite, sphalerite and what looks to be possibly a couple different species of silver sulfides (microscopic). Self collected from the dumps near the Sierra Nevada mine; may be from a different mine. ...

Dark gray acanthite and golden pyrite on quartz. I collected this specimen on the Sierra Nevada Mine dump.
