Chalcocite

specimen number:
8311134

location:
Flambeau Mine, Rusk Co., Wisconsin, USA

description:
A loose beautiful blue to purple iridescent cluster of well crystallized chalcocite. This is in super condition.

The Flambeau Mine in Rusk County, Wisconsin, was an open pit copper and gold mine that operated from 1993 to 1997. The deposit was a volcanogenic massive sulfide ore body hosted in Precambrian volcanic rocks. During mining, rich secondary enrichment zones were encountered that produced copper sulfide minerals. Chalcocite occurs at the mine as dark gray to black metallic masses and crystalline coatings formed by the alteration and enrichment of primary copper minerals such as chalcopyrite. Specimens from the Flambeau Mine are valued by collectors for their well developed sulfide mineralization and associations.
