A former underground Cu-Au-Ag-Mn-Zn-garnet mine located in the SE¼NW¼ sec. 34, T3S, T29E, G&SRM, in King Gulch, 1 mile NE of Shannon Mountain, 6 miles NNW of Clifton, on private land. This property is comprised of 2 patented claims (Antietam and Leo C.). Discovered 1875 by Charles M. and Baylor Shannon. Produced 1902 until 1918. Past owners included the Detroit Copper Mining Co. of Arizona; and, the New England and Clifton Copper Mines Co. Past operators included P.F. Crowley. Owned by the Phelps Dodge Corp., Morenci Branch.
Mineralization is an irregular ore body hosted in the Modoc Limestone, Morenci Shale and the Longfellow Limestone and associated with Morenci Granite Porphyry and Precambrian granite basement. Adjacent to Morenci Quartz Monzonite intrusion. The ore zone is 1609.3 meters long, 12.19 meters wide, with a depth to top of 0 meters, striking N-S and dipping vertically. Ore control was N-S-trending fissure vein in the granite basement. Ore concentration was surface leaching and oxidation of ores in contact-metamorphic limestone, metasomatic replacement. Surface alteration was extensive to unknown depths. Some of the largest ore bodies were originally calcareous sediments altered through leaching and oxidation with an unknown vertical extent. The ores consist chiefly of chalcopyrite and pyrite in altered granite. The vein continues northward onto the Boulder claim (property formerly of the Arizona Copper Co. Ltd.) and southward onto the old Shannon Copper Co. property.
The porphyry in the area is fragmented by masses of quartzite, limestone, and shale. NE-trending narrow porphyry dikes in the vicinity Veins in the region consist of many very sharply defined fissure planes striking NNE. Local tectonics include block faulting NW of the Copper King Massif with downthrow of about 1000 feet.
Workings are 15.24 meters deep. Developments included a 2-compartment shaft to a depth of 140 feet; and, a tramline from the mine to the Shannon railway. Analytical data: 4% Cu, $8 Au/ton, 5 oz. Ag/ton (date unknown).
