Copper

A small partially crystallized copper specimen from this historic locality. Mamainse Point has long been known as a source of copper, in particular, native copper. Since the earliest times in North America, prospectors, explorers and miners have visited the shores of Lake Superior in the Mamainse Point area to search for or mine native copper or sulphides of copper. While the deposits are nowhere near the economic significance of the famous Keweenawan copper deposits across the lake in the Upper Peninsula of Michigan, USA, they have sustained a number of economic mining operations over the years, for various lengths of time, including the Copper Creek Mine and the Tribag Mine. The Mamainse Point area is just an hour or so north of Sault Ste Marie, or “The Soo” as it is affectionately known to Canadians.
