A former surface and underground Cu-Au-Ag-Fe mine located in the NE¼ sec. 3, T6N, R13W (Salome 15 minute topo map), on land of unknown status. Owned and operated by Mattson & McDonald (1940).
Mineralization is high-grade gold with oxidized copper ores in strong hematite fissure vein cutting Precambrian metamorphics cut by diabase and granitic dikes and intruded by Laramide granite.
Workings are generally shallow shafts, tunnel, and surface cuts worked intermittently from 1935 through 1940, producing some 270 tons of ore averaging about 2% Cu, 0.62 oz. Au/T, and 0.4 oz. Ag/T.
