Rare Native Copper from Historic Phoenix Mine, Michigan
Add a Matching Display Stand
An incredible piece of Michigan mining history, over 100 years old! This Native Copper in stone specimen comes from the Phoenix Mine, Houghton Township, in Keweenaw County, Michigan. The Phoenix Mine was a prominent Copper mine operating during the mid-to-late 1800's which produced an estimated 17 million pounds of copper ore, including some fabulous collector specimens. Despite the large quantity of copper ore extracted from this location, it was not economically viable and ceased operations in the late 1920's.
This specimen features lustrous orange Native Copper crystals with gorgeous crystal twinning. The Copper crystals have a branching, elongated feather-like appearance, and are seen intermittently throughout the front and back of the stone.
