Native Copper with Barite

A striking specimen of native copper from the historic White Pine Mine in Michigan's Upper Peninsula, featuring a vibrant blue-green patina of minerals and an oxidized tenorite coating. Delicate barite contrasts beautifully against the copper's rich tones, adding depth and texture to this piece. The White Pine Mine played a vital role in Michigan's and the United States mining history, producing approximately 4 billion pounds of copper and 45 million ounces of silver during its operation. Today, the mine is flooded, and while most of its copper was refined and lost to industry, only a limited number of natural specimens remain in circulation. This piece comes with its original label, connecting it to the legacy of one of Michigan's most significant mineral-producing localities. A rare and compelling addition to any collection, preserving a piece of American mining history. See dimensions below.
