A small former underground Cu-Au-Ag mine located in the NE¼ sec. 26, T10N, R19W (Black Peak 15 minute topo map), SW of Billy Mack Mountain, 5 miles NE of Parker, on BLM-administered land. Located 5 miles NE of Parker. Owned by Osborne & Ransford.
Mineralization is associated with low-angle normal faults. The ore bodies are found within and above the flinty, chloritic, micro-brecciated, detachment surface. The ore bodies are lenticular bodies of brecciated rock with cementing hematite containing spotty secondary copper ores, limonite and some flaky gold in a wide, silicified breccia zone, probably along a thrust fault between metamorphosed Paleozoic limestone and Precambrian schistose quartzite. The ore zone strikes N-S and dips vertically. An associated rock unit is basalt.
Workings include an inclined shaft, tunnel and open cut. They are 83.82 meters in length and 68.28 meters deep. This mine was prospected and mined intermittently from the early 1900's to the 1950's, producing some 100 or more tons of ore averaging about 8% Cu, 0.4 oz. Au/T and 0.1 oz. Ag/T. In 1918-1919, this property yielded three cars of sorted, high-grade gold-copper ore.
