Massive native copper specimen weighing in at 155 grams, approx. 4 x 2 x 1-1/2 inches in size, attributed to the Ojibway Mine between Mohawk and Phoenix, Michigan on the Keweenaw Peninsula of Northern Michigan. This specimen may have been released from the surrounding rock in an acid bath, because it does not appear to be badly deformed from hammering the rock into bits to release the copper. Many fine details are retained in the structure of the copper that tell of it being deposited in the cracks and crevices of the rock from which it was recovered. The Ojibway Mine was organized in 1907 and closed in 1913 after producing 50,000 pounds of refined copper. State: Michigan City: Mohawk Date:
