Access the cache from Powderhouse Road (ATV trail #135), which branches off Burma Rd, just west of the Clark Mine Rd junction. The road is a little rocky at the start, but should be drivable by cars with care. Or park at the junction and walk in (0.75 mile to cache).
An underground copper mine consisting of four shafts and two adits located southeast of Copper Harbor, south of the Clark Mine. The Star Copper Company was organized in 1851 and 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
