Notes

Kearsarge Mine was located north of Calumet in Houghton County. There was a North Kearsarge mine and a South Kearsarge Mine. The North Mine had two shafts and was first worked in 1881. The South Mine also had two shafts and was first worked in 1897. Note: The Wolverine Mine was in-between with two more shafts and first worked in 1882.

An underground copper mine consisting of six shafts. Organized as the Kearsarge Mining Company in 1886, it worked the Kearsarge Lode on opposite sides of the Wolverine Mine and between 1887 and 1897 produced approximately 14.5 million pounds of refined copper. In 1897, the company was bought by the Osceola Consolidated Mining Company and was split into the North Kearsarge (four shafts) and the South Kearsarge (two shafts). South Kearsarge was closed in 1930 and never reopened. North Kearsarge closed in 1931, but then reopened in 1942 to supply the war effort 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.

An underground copper mine consisting of four shafts. After the buyout by the Osceola Consolidated Mining Company in 1897 and later split, the North Kearsarge Mine operated the four shafts to the northeast of the Wolverine Mine. In 1902, the No. 1 shaft was reduced to a three compartment shaft and re-timbered, rendering the No. 2 shaft inadequate for future use. No. 3 shaft was considered the best producing of the four shafts and operated until the 1956 when all operations were ceased.  [MINDAT]
