A former underground Au-Ag-Fe mine located in the SE¼ sec. 10 and sec. 3, T.1S., R.14W, about 5 miles E of the Sheep Tank Mine, on BLM-administered land. Owned at times, or in part, by Davis; and, Luke & McElrath. Operated by the Rea Gold Corp., Vancouver, Canada (1986).
Mineralization is spotty gold with silver in narrow, lenticular, quartz-carbonate stringers with limonite-filled pockets and gouge in a brecciated zone in Tertiary andesite volcanics below Quaternary basalt. The ore zone strikes N55W and dips 50N. Vein walls are chloritized, carbonatized and locally sericitized.
Workings are several shallow shafts including a shallow inclined shaft with a short crosscut and an inclined winze. Mining was sporadic from 1941 through 1950. Rea carried out geologic evaluation, surface drilling program, and identified reserves during 1984-19, and then returned the property to the owners. It produced some 15 tons of ore averaging about 12.5 oz. Au/T and 3.7 oz. Ag/T. An assay in 1932 showed the first twenty feet of depth assayed several dollars in gold per ton, but the lower portion of the shaft ran less than $2 per ton.
