A Au-Ag-Mn-Fe-Cu-Pb-Ba (Be) mining district located in T1N-T1S, R14-15W, within a mile of the southern margin of the Little Horn Mountains. Started in 1909 and owned by J.G. Wetterhall.
Mineralization is varied: (1) Gold and silver with local, minor, lead and copper mineralization in irregular vein deposits along fault zones cutting Tertiary volcanics; (2) Irregular manganese oxides in stringers, pods, and overlapping lenses along shear zones in Tertiary volcanics; and, (3) Minor gold placers.
Workings are numerous prospects, but few producing mines, worked from about 1909 through 1950, producing some 17,411 tons of precious and base metal ores containing about 20,900 oz. of gold, 39,730 oz. of silver and one ton of copper. Some 250 long tons of low-grade manganese ore and a few ounces of placer gold were also produced.
