A former small underground Cu-Zn-Ag-Pb-Fluorspar mine located in East-central sec. 23, T.15S., R.22E. (Dragoon 7.5 minute topo map). First produced 1882. Owned/operated at times, or in part, by the Russell Gold and Silver Mining Co.,Philadelphia, Pa. (1881); Dragoon Mining Co.; Bonanza Belt Copper Co.; Peabody Consolidated Copper Co.; and, the Coronado Copper & Zinc Co.
Mineralization is base metal carbonates and minor sulfides in tabular pyrometasomatic mantos along silicated layers in favorable beds along cross cutting fissures in Pennsylvanian Horquila Limestone.
Local structures include a NE-trending fault system N15-20E, 65-70E; an east-trending fault system N70E to S70E, 45-80S; a massive fracture system; Tertiary block faulting, tilting NE. Regional trend is Late Cretaceous or Early Tertiary N- to NW-trending folds and thrust faults overriding to the NE.
Workings include a pit, open cut, and shaft(s). A total of some 43,000 tons of ore were produced intermittently from 1882 to 1931.
