A former large output underground Ag-Au-Pb-Cu-Zn occurrence/mine located in T20S, R22E, on a claim of 1,500 feet (0.46 km) by 600 feet (0.18 km), ΒΎ mile S of Tombstone, on private land. Owned at times, or in part, by the Western Mining Company; the Centurion-Arizona Mining Company; the Grand Central Mining Company; the Tombstone Mill & Mining Company; the Head Center Company; the Head Center & Tranquility Company; the Contention Mining Company; the Tombstone Consolidated Mines Company; the Bunker Hill Mines Company; A.P. Giacoma; and the Tombstone Development Company.
Mineralization is oxidized argentiferous and auriferous galena and minor copper and zinc ores in large, rich orebodies in faulted and fractured segments of a large dike, and in brecciated footwall zones of the dike, hosted in the Bisbee Group Limestone. Ore was also found in replacements of Cretaceous Bisbee Group limestone beds that were intersected by "northeast" fissures. The Bisbee Group limestone is recrystallized. Associated rocks include Late Cretaceous diorite. Local rocks include Cretaceous to Late Jurassic sedimentary rocks with minor volcanic rocks.
The shaft is in the N-S Tranquility Fault, dipping 67-70SE. This fault is cut within the workings by the Grand Central Fault, which strikes NW.
Local structures include the Tombstone Basin.
Workings include underground openings with extensive shaft(s), with one to 500 feet (ca. 152 m) deep; 3 levels at 500, 600 & 1100 feet (ca. 335 m). Workings total 1524 meters long and 137.16 meters deep. Workings were on six levels, many stopes were in the upper 250 feet (ca. 76 m). The total length of workings is estimated. There are 2 shafts, the northerly shaft is the deepest. The workings adjoin the Contention workings to the north. One of the earliest and most productive mines of the district.
Over $10,000,000 (period values) was produced prior to 1886 and several hundred thousand tons were produced from the 1880s to the early 1900s. After 1886, production includes the Contention shaft. There was some sporadic production up to 1929.
