Tamarack Copper Mine (United States)


An underground copper mine located near Calumet, MI. The Tamarack Mining Co. was organized in 1882 in the hopes of profiting from the rich Calumet Conglomerate that made C&H millions of dollars. Work was started on a vertical shaft and in 1885 at a depth of 2,270 ft., the lode was intersected. Four more shafts were driven, all vertical, during the development stage. The deepest, shaft #5, intersected the lode at 4,662 ft. and was bottomed out at 5,309 ft. from the surface. The mine worked at a profit from 1887 to 1907. In 1917, Tamarack sold the property to Calumet & Hecla for $3 million, and the company was dissolved. In 35 years of operation, Tamarack produced 389,215,899 lbs. of refined copper, making Tamarack the second largest producer from the Calumet Conglomerate. A wide range of minerals can be found here, including copper, silver, cuprite, malachite, powellite, and copper "skulls".
