Copper / Silver - CUAG20

Semi-Polished Copper-Silver Specimen, Keweenaw Peninsula 

7” x 3” x 12” / 20 lbs

This very rare native metal combination was found in the Keweenaw Peninsula of Michigan; associated with native copper deposits. I polished portions of the face to expose the Copper beneath the patina; it has been coated with a thin coat of lacquer to prevent oxidization. The copper contains inclusions of cuprite, epidote, malachite and silver. Custom made metal stand included.
