Native Copper

A large cabinet specimen featuring several native copper crystals across the surface of the matrix. The copper has been acid-etched from its original calcite host, with calcite still remaining on the surface in a recessed area. Additional copper may still lie beneath, there is potential for further careful preparation by those inclined. The overall presentation is rugged and natural.

This piece comes from the historic Mamainse Point area along the north shore of Lake Superior, Ontario. Known since the earliest periods of North American exploration, Mamainse Point has long been a source of native copper, drawing prospectors and miners to its shores for generations. While not as prolific as the famous Keweenaw Peninsula deposits across the lake in Michigan, the area has supported several mining operations over time, including the Copper Creek and Tribag mines. Today, specimens from this locality are valued for their history and character, representing a classic Canadian copper occurrence.
