A Pb-Ag-Au-Cu mine located in East-central sec. 13, T.20S. R.22E. Owned at times, or in part, by the Woronoco Co., Tombstone Mining Co. and the American Smelting and Refining Co. (ASARCO).
Mineralization is largely oxidized argentiferous galena in vein-like replacements of gougy fault breccia in Cretaceous Bisbee Group beds along a strong fault zone intersected by 'northeast' fissures.
Workings include shafts. Some intermittent production occurred in the early 1900's and over 40,000 tons of ore were produced from 1930 through 1954 by the group.
