A piece of float copper sets on exhibit near the Calumet & Hecla general offices.

The largest known quantities in the world of pure, native copper were found on Michigan's Keweenaw Peninsula. In some cases, the deposits were up to 97% pure, requiring little chemical processing to produce ingots of pure copper.
