A former small underground Ag-Au-Cu-Pb-Zn mine located in the NE ¼ sec. 6, T.23S., R.11E, 1 mile W of the Montana Mine, on National Forest land. Produced 1939-1966. Owned at times, or in part, by Miller; Crowder; and, McFarland & Hullinger.
Mineralization is lensing, vuggy, quartz-fissure vein with calcite, disseminated fine-grained sulfides and sulfosalts in a fault zone intersection. The outcrop is in a NW fault cemented first by quartz and sulfides and secondly by calcite. The ore zone is 91.44 meters long and 3.66 meters wide, strikes N70W, dips 55NE and plunges 60W. Wall rock is partly propylitized, brecciated and recemented Cretaceous conglomerate, Jurassic quartz latite tuff, and Laramide diorite. Native wire silver with gold and silver enrichment in the oxidized zone. The mineralized ore shoots grade into a barren gougy fault zone on the NW & thin barren quartz stringers on the SE. Oxidation is propylitic and includes seritization. The host rock units are the Oro Blanco Formation, the Cobre Ridge Tuff; and the Ruby Hornblende Diorite.
Workings include shaft and open cut operations. Workings total 54.86 meters in length and 51.82 meters in depth. Old surface workings were reopened in 1939 and produced intermittently to 1966 some 3,700 tons of ore averaging about 17 oz. Ag/T, 0.1 oz. Au/T and minor copper. Workings flooded.
