A former small Cu-Au-Ag mine located in the SE ¼ sec. 12, T.16S., R.22E. (Dragoon 7.5 minute topo map). First produced 1908. Closed 1944. Owned by Mrs S.J. Landfair (1955) operated at times by The Centurion-Arizona Mining Co. and the Captain Mining Co. (closed 1944).
Mineralization is local replacement bodies of malachite and chrysocolla in brecciated marble with fault gouge, quartz, chalcedony, calcite and some lime silicates, along a strong fault zone between Mississippian Escabrosa and Black Prince Limestones and Precambrain Pinal schist, near intrusive Laramide quartz monzonite (Texas Canyon stock). The fault zone is sheared and silicified. Vein material is brecciated and recemented. Some natural solution caves contained ore.
Ore control was faults intersecting beds favorable for replacement, fissues. Ore concentration was supergene enrichment, replacement. Alteration was oxidation and silicification.
Local structures include the Centurion Fault, striking N68W and dipping 74SW; Tertiary block faulting trending NW. Regionally, Late Cretaceous or Early Tertiary N- and NW-trending folds and thrust faults overriding to the NE.
Workings include shaft(s). A total of more than 1,400 tons of ore were produced intermittently from 1911 to 1944.
Part of the ore came from small concentrations along faults and fissures, detritus in solution caves and locally mineralized beds. Location 1 INFO FROM LAND.ST :(1979)
