|Location and accuracy||Homestake Creek is a west tributary of the Kougarok River. The mouth of Homestake Creek is 2,500 feet upstream from the mouth of Taylor Creek. Sainsbury and others (1969) show the lower 5,000 feet of the channel of Homestake Creek to have been placer mined. This is locality 37 of Cobb (1972; MF 417; 1975; OFR 75-429).|
Geologic descriptionPlacer mining for gold took place here as early as 1903 (Brooks, 1904). Sainsbury and others (1969) show the lower 5,000 feet of Homestake Creek to have been placer mined. One-fourth mile upstream from the mouth, mining encountered 4 to 5 feet of muck over fine sand on bedrock (Collier and others, 1908). Some of the gold is coarse with a nugget worth $14.40 (0.8 ounces) being recovered by early operations (Collier and others, 1908). Scheelite is reported to be present in the placer deposits (Anderson, 1947; Moxham and West, 1953). Bedrock is extensively mantled by tundra in the area but where exposed in nearby uplands it is part of a low grade, lower Paleozoic metasedimentary assemblage (Sainsbury and others, 1969; Till and others, 1986). Some bedrock , graphitic and calcareous mica schist, was apparently exposed by early mining operations (Collier and others, 1908). Placer deposits on the active floodplains of the area are probably the result of at least two cycles of erosion and placer developement.
