Location: Rock Creek is west tributary to Slate Creek (SO138); Slate Creek is a south tributary to the Pilgrim River. The mouth of Slate Creek is about 3.5 miles downstream from the head of the Pilgrim River on Salmon Lake. This location is at the mouth of Rock Creek. It is included with locality 25 of Cobb (1972, MF 445; 1978, OF 78-181).
Geology: Placer mining on Rock Creek reportedly took place before 1908 (Smith, 1909). Additional information is not available but mining was probably in conjunction with activities on Slate Creek (SO138). Bedrock in this area is mostly part of a lower Paleozoic metasedimentary assemblage (Till and others, 1986).
Workings: Some small-scale placer mining took place on this creek before 1908.
Age: Quaternary.

Commodities (Major) - Au
Development Status: Yes; small
Deposit Model: Placer Au-PGE (Cox and Singer, 1986; model 39a).
