Michigan Native Copper Slice Michigan Copper Slice:#4 as agate's natural vibrations areA unique polished slice of Michigan Native Copper. Michigan's Keweenaw Peninsula is the most important locality in the world for pure native copper. Mining operations began in 1845 and continued until 1968, yielding more than 5 million tons of refined copper from Michigans copper mines. In the early 1900s, the region led the world in copper production, and Lake Copper became the purity standard against which other refined copper was measured.
