An former underground Cu-Au-Ag-Baryte-Fe-Fluorspar mine located in the NEΒΌ sec. 12, T8N, R15W, about 20 air miles NW of Wenden, on BLM-administered land.
Mineralization is a vein deposit in a shear zone with spotty, oxidized copper minerals with strong hematite and quartz and local barite, minor fluorite, and traces of sulfides in irregular fault veins or replacement deposits in Precambrian gneiss and schist and granitic breccia, cut by pegmatite, aplite and amphibolite dikes. The ore zone is 0.1 meters wide, strikes S52E, and dips 60NE. Some epidote and chlorite. Ore concentration was through the oxidation of lean primary ores. The presence of baryte and fluorite indicates a late introduction, and solutions bringing in these minerals are possibloy responsible for the concentration.
Workings include an inclined shaft sunk in the 1890's into the early 1900's, during prospecting, to a depth of 57.91 meters deep. A small amount of ore was produced averaging about 16% Cu, 0.8 oz. Au/T, and 1.3 oz. Ag/T in 1907. One carload of ore has been shipped, which is reported to have carried 22% Cu and from $4 to $5 in Au/T (period values).
