Large Cabinet, 21.4 x 13.8 x 1.3 cm
White Pine Mine, White Pine, Ontonagon Co., Michigan, USA
A fine, sculptural, large cabinet sheet of native copper from the White Pine Mine of Michigan. This striking piece has aborescent form, a nice patina and remaining shale, as an accent. Native copper was deposited in shale beds of the Nonesuch Shale, explaining the sheet-like form. The White Pine was the last major copper mine to close in the historic Copper Country. Large plates such as this, which formed naturally between the shale beds, are now harder to obtain. Ex. Consie Prince Collection.
