Item Description

Striking, highly unusual form on this large, flattened, two-sided large copper specimen from the well-known extinct White Pine Mine of Michigan's famous Copper Country. The bizarre laminated copper on this specimens looks like bridge girders. The filagree of spinel-twinned copper crystals accented with malachite on both side of the large 'V' adds a captivating and colorful visual aspect to this rare style copper. The narrow end of the piece resembles a dragon's head. 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. From an old collection. This exotic looking two-sided copper has two fine display views. It came to us in an old collection.
