Arizona Bureau of Mines file data.
A Ag-Au-Pb-Cu-W mine located in West-central sec. 12, T.18S., R.15E. Owned at times, or in part, by the Iowa Mining & Development Co.; the Good Friday Mining Co.; Corzelius; and, Taggert & Drunzer.
Mineralization is tabular replacement deposits of sulfides, oxidized near the surface, with rich chlorargyrite and free gold, along steep bedding planes and lamprophyric dikes in Permian limestone bordering Laramide intrusive quartz monzonite. Some copper staining and scheelite in the area.
Workings include tunnel, shaft and open cuts. Worked sporadically from 1881 to 1939, producing some 2,300 tons of ore together with the Blue Jay Mine, averaging about 21 oz. Ag/T, 1 oz. Au/T, and minor Pb. High-grade Ag-Au ore in surface cuts.
