A former small surface and underground Cu-Ag-Au-Pb-Zn mine located in the center of sec. 25, T.15S., R.22E. (Dragoon 7.5 minute topo map), 0.8 miles east of the town of Johnson. Owners included the Peacock Mining Co. Operators included N.R. Miller.
Mineralization is copper carbonates in narrow replacement deposits in Pennsylvanian Horquila Limestone cut by small porphyry dikes. Ore control was the beds near NE-trending faults and folds. The beds strike NW and dip 40NE. An associated rock unit is the Texas Canyon Quartz Monzonite (53 ± 3 MY).
Local structures include a massive facture system. Tertiary block faulting with a general NE trend.
Workings include a shaft and tunnel workings. A total of some 60-70 tons of ore were shipped in 1908, 1912 and 1942.
