An underground copper mine consisting of several shafts near the town of Victoria, MI. The mine first opened in 1849 as the Cushin Mine and was organized as part of the Forest Mining Co. in 1850. In 1852, the Glenn Mining Co. was set off from Forest, then reorganized in 1858 as the Victoria Mining Co. The mine worked sporadically until 1899, when the company was reorganized as the Victoria Copper Mining Co. This new company included the old Victoria, Glenn, Shirley, Sylvan, Oneida, and Arctic Mining Co's. Operations ran from 1904 to 1921, when the company closed for good. Between 1850 and 1921, the Victoria Mines produced approx. 20 million lbs. of refined copper. The mine piles have produced copper and silver crystals, and a few datolite nodules.
9 valid minerals.
