A former small underground Pb-Ag-Zn-Cu-Au mine located on 3 patented claims in the West-central sec. 30, T.22S., R.16E, on the SW side of Alum Gulch, 4.0 miles S of Patagonia; 1/2 mile NE of the Blue Eagle Mine, on private land. Produced sporadically from the 1890's to 1920. Owned/operated by, or in part, by R.R. Richardson; Allison Brothers; W.P. Wilson; E.E. Bethel; and the Flux Extension Mining Co. Mining Co.

Mineralization is the northward extension of the Flux Mine mineralization (the complex Flux Mine Fault System). A small lode type deposit of argentiferous lead, zinc, and minor copper and gold ores along a fault-fissure zone cutting crushed, altered, and silicified Jurassic-Triassic rhyolitic volcanics and fault blocks of Paleozoic limestone occurring mainly in the N-S-trending shear zone or lode. The ore zone is 2,413.95 meters long. The lode narrows with depth. Secondary enrichment along brecciated zones. Surface oxidation exists to depths of 250 feet with pyrite gossan at surface. An associated rock unit is the Mt. Wrightson Formation.

Local structures include sedimentary rocks locally intruded by quartz monzonite (?) and granitic aplite. Rhyolite volcanics are crushed, altered, and silicified. The rhyolite contains isolated exotic blocks of Upper Paleozoic limestone. A general structure common to regional formations is a sheeting which dips 40 NNW.

Tectonic elements include the Alum Gulch Fault Block and complex fault systems associated with the Harshaw Creek Fault.

Workings include shaft and tunnel operations. Workings included a 250-foot cross cut driven to strike the ore body at depth, a shaft, and an adit. Worked sporadically from the 1890's to 1920. Produced some 300 tons of ore averaging about 15% Pb, 6 oz. Ag/T and minor Cu and Au.
