  • Coppermine River
  • NE of Great Bear Lake
    Northwest Territories, Canada
  • The Coppermine River area was once a very prospective area for copper, due to the seemingly large amounts of native copper and other copper minerals in the area. I don't think any "coppermines" actually resulted but it remains very prospective and an interesting area geologically!

  • Keweenaw Peninsula

  • Michigan, USA
  • This piece is solid native copper but not a natural form. It is a "chisel chip", a fragment resulting from the practice of chiseling down huge boulders of copper by miners. Really big boulders of native copper could not be crushed down in size but still had great value as copper. They are metal and so could not be blasted down in size, either. The COULD be chiseled down in size, though! This chisel chip is a result of that kind of work.
