Clark Mine

In 1853 the Clark Mining Company was formed and began work on a small copper vein located approximately 3 miles southeast of Copper Harbor. Mining continued off and on under multiple property owners until 1902. Eight shafts and three adits compose the mine and the smokestack of the mine’s powerhouse still remains at this historic site. Copper crystals in and on the prehnite are sought after remnants by rock hounds, while many other minerals have been reported in this locality.
