Nice chunk of fresh Chalcocite with a shiny gray color. It is a little sectile with a grayish black streak. Chalcocite can be confused with the less common Digenite, which will carry a bluish black color when fresh. Chalcocite is nearly 80% Copper, which of course is a major ore.
The primary source of Chalcocite in the USA is the southwest corner of Arizona. The district started with small underground mines, where rich veins of copper sulfide minerals were encountered. Bornite, Chalcopyrite, Enargite, Cuprite and Covellite, were later found in "blanket" deposits formed by supergene enrichment, which prompted open pit mining by 1937. Today, the low-grade copper at the Morenci mine is found in disseminations through out the large copper porphyry deposit.

Interest in the Encampment area for mining began in 1876 veins of Quartz carrying silver, lead, and gold was discovered Frank O. Williams on Bridger group of claims near the Continental Divide several miles north of Encampment. The largest producer was the Farris-Haggarty mine which produced rich ore of copper from 1898 to 1902, when it was purchased by the North American Copper Company who produced copper concentrates and operated a 16 mile aerial tramway to the Ferris-Haggerty mine. This
This specimen was collected from the old millsite at the mine. It contains 1 to 2cm Chalcopyrite anhedral crystals in Quartz.
