American Eagle; Am. Eagle
A former Ag-Au-Cu-Pb-Fe occurrence/mine located 1.2 km (0.7 mile) E of Mammoth (head of canyon, 3000 feet S 57 W of Mammoth Peak on lower W slope of the mountain), on private land. Owned by the Gold Chain Mining Co., C/O E.S. Mcintyre, Eureka, Utah. Operated by the Mammoth Mining Company (1930- ). MRDS database accuracy for this location is not stated. Consolidated in 1909 with the Cleveland, Pedro and Gold Chain group as the Gold Chain Mine. Explored in 1926 from the 1800 level of the Lower Mammoth Mine.
Mineralization is hosted in Late Cambrian dolomite (Ajax Dolomite; Opex Formation). The ore body is a chimney with a length of 609.6 meters, a depth-to-bottom of 304.8 meters. North-trending fissures with NE offshoots are present. Beds strike N55W and dip 20NE. Fractures trend N-S, N25E, N35E, N65E, N55W and dip 70-90W. Gossan deposit. Strikes N to W of the Mammoth pipe. Local geologic structures include horizontal ore shoots along beddings. Local alteration includes contact metamorphism. Associated rocks include Pliocene-Late Cambrian monzonite. Local rocks include Upper Cambrian carbonate rocks in central Utah.
Workings include underground openings with an overall depth of 335.28 meters and an overall length of 609.6 meters. The old shaft is caved into the stopes and is dangerous. There is a 400 foot adit (Ajax adit), an internal shaft (winze ?) and shallow surface workings. The Ajax shaft at 1,100 feet deep was used in 1917, and was sunk from the Ajax adit 400 feet from the portal. In all there are several shafts.
Production amounted to $3,000,000 (period values) of Cu, Ag & Au from the Ajax and Gold Chain mines during the period 1899 to 1917.
Analytical data results: 0.6 ounce Au; 2 to 14 ounces Ag; 2 to 8% Cu; 50 to 70% Si; 1% Zn.
