Large Native Copper sheet

Item Description

Sculptural large thin sheet native copper from the famous White Pine Mine of Michigan. This striking piece has fine form. The bright patina and remaining bits of shale, are a super accent. Looks great from either side! Native copper was deposited in shale beds of the Nonesuch Shale, explaining the sheet-like form. The mine was the only major producer from the Nonesuch Shale in Copper Country. The rest of the mines produced copper and silver from fissures, amygdaloidal basalt and conglomerate. The White Pine was the last major copper mine to close in the historic Copper Country in 1995. Large plates like this are now harder to obtain on the market compared to even a decade ago.
