Star Mine, Copper Harbor, Keweenaw Co., Michigan, USA

An underground copper mine consisting of four shafts and two adits located southeast of Copper Harbor, or one mile south of the Clark Mine. The Star Copper Company was organized in 1851 nad began producing copper in 1855. Work was suspended in 1859, but resumed in 1864 due to rising copper prices. Prices dropped again in 1865, forcing the mine to close once again. The mine reopened briefly in 1872 and again in 1881 but closed permanently in 1882. The company remained organized in hopes of reopening the mine, but never did. The property was sold around 1908 to Calumet & Hecla Mining Co.
As with Clark Mine, datolite is the main attraction here, and some very nice specimens can still be found on the rock piles. Prehnite and copper can also be found here. Beware however, that the piles are covered with 120+ years of overgrowth, so finding them can be tricky.
