Location: This prospect is on Russian John Creek in the SE1/4 section 9, T. 21 S., R. 16 E., Fairbanks Meridian. The prospect probably continues east on section 10. The prospect is at the point where a trail meets the creek (see Mount Hayes A-2 quadrangle).
Geology: A bench placer on the west side of the Middle Fork Chistochina River is at least 3 miles long. It extends southerly from Bedrock Creek (MH310), through Limestone (MH309), Kraemer (MH311), and Ptarmigan Creeks (MH312) to Russian John Creek. Russian John Creek is about 2 miles long. The upper creek is in a canyon. The lower 1.25 miles flows easterly on the Middle Fork bench into Limestone Creek, which flows south west of the broad braided channel of the Middle Fork. There is no specific prospect information on Russian John Creek. It is assumed that the bench placer deposit at Russian John Creek contains some platinum group element (or PGE) minerals and gold, as do the upstream occurrences. Upstream, the bench gravels were as much as 70 feet thick but generally less than 40 feet (Moffit, 1944).
Workings: Claims that included Russian John Creek were part of the group owned by Middle Fork Mining Company of Seattle. The claims were explored during the late 1930's, and a hydraulic mining operation started in 1941 (Moffit, 1944). The operation was effectively terminated by World War II (Moffit, 1954).
Age: Pleistocene to Holocene.
Reserves: Possible part of a low-grade gold resource on a mile-wide bench on the west side of the Middle Fork Chistochina River.
Commodities (Major) - Au; (Minor) - Ag, platinum group elements (PGE) (?)
Development Status: Undetermined.
Deposit Model: Placer Au-PGE (Cox and Singer, 1986; model 39a).
