A former small surface and underground Cu-Ag-Au mine located in West-central (SW¼SW¼NW¼) sec. 21, T.23S., R.24E. (Bisbee 7.5 minute topo map), on private land. Owned by the Phelps Dodge Corp.
Mineralization is a replacement deposit with oxidized copper ores in irregular replacement bodies in the upper part of the Cambrian Abrigo Limestone along strong faulting. The ore bodies are near dikes and sills, and faulting and associated brecciation. Ore concentration was bornite replacing pyrite. Alteration was gossan with Mn and Fe oxides induced by hydrothermal metamorphism. An associated rock unit is the Sacramento Hill Stock.
Local structures include common pre-mineralization faulting and tilting. The main fault directions are N10W to N40E and S30W to N50W.
Workings include an open cut and a shaft(s). Several thousand tons of ore were produced in the late 1800's. Production from this mine was included under the Copper Queen Branch of Phelps Dodge in USBM-ABGMT files.
