A former placer hydraulic Au-Ag-Zr occurrence/mine located in the SE¼ sec. 15, T4N, R9E, MDM, 0.5 km (0.3 mile) ENE of Wallace. Operated from prior to 1932 to the early 1940's. MRDS database stated accuracy for this location is 1,000 meters.
Mineralization is a placer Au-Ag-Zr deposit hosted in gravel. The gravel is 5 to 40 feet thick and contains 10% boulders and 20% clay. The black sands here contain Zr minerals at a concentration of 128 pounds per ton of black sand. Local rocks include Miocene nonmarine rocks.
4½ million cubic yards of gravel were washed prior to 1932. 10,000 cubic yards were washed in the early 1940's with the recovery of 286 ounces Au and 14 ounces Ag. Dredged by dragline in the late 1930's. The gravel mined in 1941 was by bulldozer with a stationary washing plant.
