A former underground Mn-Cu mine located in the NW¼NW¼ sec. 24, T1N, R15E, at the head of Buffalo Gulch, 3000 feet N of the Old Dominion Mine, about 2 miles N of Globe, on private land. Discovered 1954. Originally one of the claims of the Old Dominion Mine. Owned by the Miami Copper Co. (1961). Operated by Mr. F.A. Sitton (1953).

Mineralization is a vein deposit with an irregular ore body hosted in the Escabrosa Limestone. The ore zone is 182.88 meters long and 30.48 meters wide, strikes N40E and dips vertically. Ore control was a broad fracture zone along the west side of a tilted block of limestone. Ore concentration involved the Mn ore following favorable beds of the moderately dipping limestone in some places, adjacent to the steeper fractures. An associated rock unit is dacite.

Workings are 24.38 meters long and 3.66 meters wide. Workings include two old inaccessible shafts of unknown depths. Evidently this work had been done decades earlier in a search for Cu-Ag ores. The first Mn ore was said to have been shipped during WWII; the amount and grade of these shipments are not known.

Batch-scale, sink-and-float, flotation and sulfur dioxide leaching tests were made on a composite sample of broken ore. The sample weighed about 350 pounds and assayed 19% Mn, 38% CaCO3, 0.98% Pb, 1.70% Zn, and 0.07% Cu.
