A former small underground Mn-Ag-Pb mine group located in the NE ¼ sec. 23, T.20S., R.22E, 2 miles S of Tombstone, on private land. Operated at times, or in part, by the Old Glory Mining Co., Tombstone Consolidated Mines Co., and the Tombstone Development Co.
Mineralization is a replacement deposit with largely oxidized, vein-like, replacement bodies of manganese-silver ore in and along the footwall of a dike cutting thick-bedded Pennsylvanian-Permian Naco Group limestone. The ore zone is 419.1 meters long and 3.05 meters wide, with a 70W plunge. Ore control was a NE fissure, dike, or pre-minealization fault cutting a permeable horizon. The fissure vein parallels the fault. The deposit is NE of the Ajax Hill Horst. A Mn-Ag mineralization phase occurred after an Fe-Pb-Zn mineralization phase.
Workings include a shaft with 3 levels with upward stopes from each. Workings have a total estimated length of 914.4 meters and a depth of 121.92 meters. At least 10,000 tons of ore were produced from the late 1800's to the 1920's. Production was listed under the Tombstone group.
