|Location and accuracy||California Creek is a small west tributary to Kougarok River. The mouth of California Creek is 3.2 miles south of Taylor. Sainsbury and others (1969) show the lower 1,500 feet of the main channel of California Creek to have been placer mined. This is locality 31 of Cobb (1972; MF 417; 1975; OFR 75-429).|
Geologic descriptionThe presence of gold on the active floodplain and on benches 20 feet above it was noted in early reports (Collier and others, 1908). Sainsbury and others (1969) show the lower 1,500 feet of the main channel of California Creek to have been placer mined but the early reports indicate the benches were also mined. Gold on the active floodplain may be reworked from the nearby benches and these are probably remnants of Kougarok River terraces. There may not be a local bedrock source for the gold mined here. Bedrock of the area is extensively coverd by tundra, but upland exposures are primarily Lower Paleozoic metasedimentary rocks (Sainsbury and others, 1969; Till and others, 1986).

|Mineral deposit model||Placer Au-PGE (Cox and Singer, 1986; model 39a)|
|Mineral deposit model number||39a|
|Age of mineralization||Quaternary; placers on present floodplains are probably the result of at least two cycles of erosion and placer development.|
|Workings or exploration||Sainsbury and others (1969) show the lower 1,500 feet of the main channel of California Creek to have been open-cut placer mined but the early reports indicate the benches were also mined.|
|Indication of production||Yes; small|
