A former underground Cu-Ag-Au mine located on 2 patented claims (Solid Copper and Copper Bullion), in the SW¼ sec. 2, T4S, R29E, about 2 miles East of the Metcalf site, in the Copper King Mountain area, on private land. Situated near Rocky Gulch, SE of Copper King Mountain; about 200 feet below the summit of Copper King Mountain on its SE slope. Discovered by the New England Mining Co. Produced 1906-1910. Owned by the Phelps Dodge Corp., Morenci Branch. Past operators included the New England and Clifton Consolidated Copper Co; and the Detroit Copper Mining Co. of Arizona.
Mineralization is a tabular ore body associated with Morenci Granite Porphyry. The ore zone is 121.92 meters long and 2.44 meters wide, striking NE and dipping 70-76 NW. Ore control was a NE-trending fissure. The concentration process was surface leaching of carbonate ores. Alteration is oxidation to 300 feet of depth.
Local structures include block faulting with a prominent fault trending NE of the SE side of Copper King Mountain, and NE-trending granite porphyry dikes.
Tectonic component is Cpper King Mountain and the transition zone between the Basin and Range and Colorado Plateau Provinces.
Ore assays at $1 to $4 of Au per ton (period values).
Workings are 1066.8 meters long and 243.84 meters deep. The length of workings was estimated; 2 shafts. Description applies to the West shoot; the North shoot was undeveloped at the time of the latest MRDS data.
