An underground copper mine consisting of 2 locations; North Kearsarge (2 shafts) and South Kearsarge (2 shafts). Organized as the Kearsarge Mining Co. in 1886 and was absorbed by the Osceloa Consolidated Mining Co. in 1897. It worked the Kearsarge Lode and between 1887 and 1897 produced approx. 14.5 million lbs. of refined copper. S. Kearsarge was closed in 1930. N. Kearsarge closed in 1931, then reopened in 1942 and continued until 1956, when it was closed for good. The Kearsarge Mines are one of the best silver producers for specimens in the Keweenaw. Both mines, however, are privately owned by individuals.
