A copper mine located at Mohawk (headframe hamlet), approximately 6 miles north of Calumet on the east side of Route 41.
The Mohawk Mining Co. was incorporated in 1898 with Joseph Gay as president, after lumberman Ernest Koch found copper on the property in 1896. It is best known to collectors for the occurrence of mohawkite (a mixture of algodonite, domeykite, and copper). The mine also produced a large amount of native silver, especially in the upper levels. In 1923 the Mohawk Mining Co. took over the Wolverine Copper Mining Co. and the Michigan Copper Mining Co.
