An underground copper mine consisting of three shafts near Mt. Bohemia in Keweenaw County. An association was formed in 1845 to mine Mt. Bohemia in hopes of finding minerals. During this time miners opened a shaft and several exploration pits and trenches. The Bohemian Mining Company was organized in 1851 to continue exploration of the mountain. Work continued on and off for several years until 1864 when all work stopped. In the early 1900’s, one of the shafts was reopened for exploratory work. All work ceased in 1914 for good. At no time were profitable copper deposits discovered. It is said that the shafts are very difficult to find, and even the most seasoned local collectors have not been able to re-discover these shafts. Many minerals that are different for the Keweenaw, according to geologic reports, can be found (if the piles can be located), including digenite, djurleite, galena, sphalerite, and covellite.
