This prospect is within the Wrangell-St. Elias National Park.
Location: This prospect is located between Pouch and Kings Creeks on the north side of Elliott Creek; it is at an elevation of 4,400 feet in the NW1/4 section 1, T. 3 S., R. 7 E., of the Copper River Meridian. This prospect is approximately located, probably to within about one-half mile. It is locality 68 of Cobb and Matson (1972) and included in locality 56 of Winkler and others (1981 [OFR 80-892-B]). Cobb (1979 [OFR 79-1241]) incuded this prospect under the name 'Elliot Cr.'.
Geology: Thin veins, films, and disseminations of bornite, chalcocite, and pyrite cut Triassic Nikolai Greenstone in this area (Moffit and Maddren, 1908, 1909; Moffit and Mertie, 1923). Gangue minerals are commonly quartz, calcite, and epidote; secondary copper minerals include malachite, azurite, and some chalcanthite. Some mineralization occurs as irregular pods in greenstone. The Nikolai Greenstone and overlying Chitistone Limestone are deformed into a large, asymmetric anticline with its axis approximately parallel to Elliot 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: Prospects in the Elliot Creek area were mostly explored with small open cuts (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).
