High-grade gold-bismuth-sulfide ore, approx 60 x 55 mm, from the Florence Mine in Goldfield, Nevada. Blue-gray quartz with greenish-yellow efflorescence suggesting the presence of copper minerals. Bismuth is known to occur in the district along with tellurium and antimony, which could be incorporated in the bismuthinite, famatinite, and goldfieldite identified by the original collector. This describer can see occasional flecks of pyrite amidst the copper and iron-oxide staining. State: Nevada City: Goldfield Date:
