A small former underground Au-Ag-Cu-Fe mine located in North-central (SE¼NW¼) sec. 4, T9N, R17W, E of Osborne Wash, N of the New Standard Mine, 4 miles W of Planet Peak, on BLM-administered land. Owned at times, or in part, by Denton, Osborne. Produced 1911-1912.
Mineralization is small, irregular veins, disseminations, tabular replacements, and breccia fillings of azurite and malachite, with hematite, in thin marble layers on or near the intersection of faults and fractures with a thrust fault contact zone bringing Paleozoic limestone over Precambrian metamorphics. It is associated with low-angle detachment faulting; ore bodies are within and immediately above the flinty, chloritic, micro-brecciated detachment surface. Some concentration of gold occurred near the surface and chalcopyrite was reported in depth.
Workings reached a depth of 15.24 meters and consisted of a 50 foot shaft with several adit tunnels. This mine was prospected and worked sporadically from a shaft, from the early 1900's, but with only a few tens of tons of ore produced, averaging about 2 oz. Au/T, 0.2 oz. Ag/T and a little copper.
