Covellite with Pyrite

Leonard Mine, Butte, Silver Bow County, Montana, United States
minID: QKY-80M
54mm x 43mm x 32mm
Several free standing crystals of Covellite on different sides of the Pyrite matrix are showing dark blue patina. From the remarkable collection of John Marshall who worked at the mine from 1950 to 51. John worked as a miner despite his Harvard education he enjoyed the direct contact and collecting during his lunch breaks. His hand painted mark is on the specimen #1294. The crystals are quite lustrous and in rather good but not perfect condition as is typical for this delicate mineral, far better than average. The Pyrite is in both small octahedrons and other more complex pyritohedrons. The Covellites of Butte have always been prized and are hard to find with any quality and often incredibly costly when they are exceptional A good value.
