A former surface and underground Au-Ag-Cu-Pb-Zn mine group located in the NE¼ & center of sec. 34, T4S, R18W (protracted), on federal land. Owned and operated at times, or in part, by the Big Eye Mining Co., Big Eye Mining & Milling Co., Owned and operated by Ketcherside, Grover, Crowder & Green(1920). Owned and operated by Mr. Hudson (1951).

Mineralization is spotty gold and silver values, with minor, largely oxidized base metals in narrow, lenticular, shallow ore shoots of brecciated quartz with stringers of crystalline and manganiferous calcite, in a brecciated fault zone cutting steeply-dipping, kaolinized and chloritized Cretaceous andesite flows, intruded by a rhyolite porphyry dike and apparently faulted against badly shattered Mesozoic quartzite. A relatively small outcrop of intrusive Laramide syenite lies along the strike of the zone and probably underlies the volcanics in a much wider area.

Workings include a tunnel, shaft and open cut operations. This group was worked sporadically from about 1910 through 1951, producing a total of some 2,370 tons of ore averaging about 0.9 oz. Au/T, 8 oz. Ag/T and minor Cu & Pb.
