This prospect is within the Wrangell-St. Elias National Park.
Location: This prospect is near Rainbow Creek on the north side of Elliott Creek valley (Moffit and Mertie, 1923, locality 21, plate 3); it is at an elevation of about 4,100 feet in the SW1/4 section 35, T. 2 S., R. 7 E., of the Copper River Meridian. This prospect is approximately located, perhaps to within one-half mile. It is included in locality 65 Cobb and Matson (1972) and locality 55 of Winkler and others (1981 [OFR 80-892-B]).
Geology: A shear zone in Triassic Nikolai Greenstone contains a 4-foot-thick, 8-foot-long, tabular, fault-bounded body with bornite, chalcopyrite,and pyrite (Mendenhall and Schrader, 1903; Moffit and Mertie, 1923). Bornite and chalcopyrite also occur in sheeted calcite veins and associated with quartz and calcite in fracture zones. The lenticular mineralization at the Goodyear prospect may be a faulted segment of the sulfide-bearing body at the Henry Prather prospect (VA032). The Goodyear prospect was explored by a 300-foot-long adit and at least one open cut by 1923 (Moffit and Mertie, 1923). The Nikolai Greenstone and overlying Chitistone Limestone are deformed into a large, asymmetric anticline with its axis approximately parallel to Elliott Creek. The copper mineralization is believed to be related to the regional mineralizing event that produced the rich Kennecott copper deposits in the McCarthy quadrangle (MacKevett and others, 1997).
Workings: The Goodyear prospect was explored by a 300-foot-long adit and at least one open cut by 1923 (Moffit and Mertie, 1923).
Age: The copper mineralization is believed to be related to the mineralizing event that produced the rich Kennecott copper deposits in the McCarthy quadrangle to the east (MacKevett and others, 1997). This event is interpreted to have accompanied Late Jurassic or Early Cretaceous deformation and metamorphism (MacKevett and others, 1997, p. 88).
