WulfenitePure Potential Mine, Silver District, Trigo Mts, La Paz Co., Arizona, USA
Latitude: 33°7'16"N
Longitude: 114°36'41"W
A former underground Pb-Zn-Ag-Fe-Mo-V-F mine located in East-central & the SE¼ of sec. 34, T3S, R23W, about 1.25 miles NW of the Red Cloud Mine, on BLM-administered land. Owned by Neal Mining Co. Operated in recent years for specimens.
Mineralization is argentiferous lead sulfate and carbonate, zinc carbonate, lead oxide, wulfenite, and partly altered streaks of galena in irregular bunches or in vugs in irregular lensing veins along a northward-trending fault zone that dips 35ºE., cutting Tertiary-Cretaceous rhyolite tuffs and andesitic flows. Northern part of the deposit is in fault contact with granodiorite. An irregular vein, to a few feet in maximum width occurs within the fault zone. Gangue is iron oxides, manganiferous calcite, quartz and fluorite. Ore said to average 6% Pb and 8 oz. Ag/T.
Workings include an 80 foot deep shaft and 2 short drifts on the 25 level. May have been mined in the 1880's. Operated under claim in recent years as the Pure Potential mine for specimens (vanadinite, fluorescent specimens). NOTE: This property is still under claim and lease - NO TRESPASSING.
