A former medium output underground Cu-Pb-Zn-Au-Ag mine located in the West-central (SW¼NE¼SW¼) sec. 15, T.23S., R.24E. (Bisbee 7.5 minute topo map), approximately ¼ mile West of Lowell, on private land. Owned by the Superior and Pittsburg Co., the Calumet & Arizona Mining Co. and the Phelps Dodge Corp.
Mineralization is mainly oxidized, large, irregular replacement orebodies of copper, and some lead and zinc, ores in relatively unaltered Mississippian Escabrosa Limestone along the edges of a porphyry dike (Sacramento Dike). Ore control was nearby 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. Gossans found several hundred feet below the water line.
Local structures include pre-mineralization faulting and tilting. Main fault directions are N10W to N40E and S30W to N50W.
Workings include a shaft(s) to 457.2 meters deep. Several hundred thousand tons of ore were produced as part of the Calumet & Arizona and Phelps Dodge totals.
