A former large output underground Ag-Au-Pb-Cu-Zn mine located in T20S, R22E, on a claim of 1,500 feet by 600 feet, ¾ mile S of Tombstone, on private land. Owned at times, or in part, by the Western Mining Co.; the Centurion-Arizona Mining Co.; the Grand Central Mining Co.; the Tombstone Mill & Mining Co.; the Head Center Co.; the Head Center & Tranquility Co.; the Contention Mining Co.; the Tombstone Consolidated Mines Co.; the Bunker Hill Mines Co.; A.P. Giacoma; and the Tombstone Development Co.

Mineralization is oxidized argentiferous and auriferous galena and minor copper and zinc ores in large, rich ore bodies in faulted and fractured segments of a large dike, and in brecciated footwall zones of the dike. Ore was also found in replacements of Cretaceous Bisbee Group limestone beds where intersected by "northeast" fissures. The Bisbee Group limestone is recrystallized.

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 included extensive shaft(s), with one to 500 feet deep; 3 levels at 500, 600 & 1100 feet. Workings total 1524 meters long and 137.16 meters deep. Workings were on six levels, many stopes were in the upper 250 feet. The total length of workings is estimated. There are 2 shafts with the northerly shaft is 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 1880's to the early 1900's. After 1886, production includes the Contention shaft. There was some sporadic production up to 1929.
