A former underground Cu-Ag-Au-Gypsum group of mines located in the center (NE¼SE¼NW¼) of sec. 31, T7N, R17W and sec. 7, T6N, R17W (Bouse 15 minute topo map), on land of unknown status. Owned at times, or in part, by the Coronation Mining Co. The Blue Sky Mining Co. had unspecified involvement here (1950).
Mineralization is spotty copper, silver, and gold ores, largely oxidized, in irregular quartz veins along fractures in Precambrian gneiss.
Workings include shallow shaft(s). Worked mainly in the 1940's and early 1950's, producing some 115 tons of ore averaging about 1.8% Cu, 0.13 oz. Ag/T and 0.07 oz. Au/T.
