Location: Rulby Creek is a small east tributary to Sinuk River (NM015). The mouth of Rulby Creek is 0.6 mile downstream of the mouth of American Creek. It is locality 68 of Cobb (1972 [MF 463], 1978 [OFR 78-93]).
Geology: Rulby Creek was prospected and produced a little placer gold in the early 1900's (Collier and others, 1908). The creek flows across a higher gravel deposit, probably glacial, that carries small amounts of gold. This locality is within an area of iron and related base metal mineralization (NM014, NM014, NM017, NM018, NM019, and NM020) that locally includes some anomalous gold values (for example, NM014).
Workings: Some gold was produced by pan, rocker, or other small scale operations in the early 1900's.
Age: Quaternary.
