Location: A 2,000 foot-long segment of the Solomon River has been placer mined from the mouth of Coal Creek downstream for 500 feet past the mouth of Johns Creek. This is locality 97 of Cobb (1972, MF 445; 1978, OF 78-181).
Geology: Stream gravels about 4-feet thick in the flood plain of Solomon River were dredged between 1929 and 1932; the paystreak was up to 700-800 feet wide (Smith, 1933). Bedrock in the area is part of a lower Paleozoic metasedimentary assemblage (Till and others, 1986).
Workings: Small-scale hydraulic and dredging operations took place along this segment of the Solomon river from 1929 to 1932.
Age: Quaternary.

Commodities (Major) - Au
Development Status: Yes; small
