Location: Collins Creek is a southern tributary to Hannum Creek. The mouth of Collins Creek is 1.5 miles upstream of the confluence of Hannum Creek and Inmachuk River. This is locality 70 of Cobb (1972; MF 417; 1975; OFR 75-429).
Geology: Coarse gold (Moffit, 1905) and lead minerals including lead carbonates, pyromorphite, and galena are reported from gravels in this creek (Anderson, 1947), but information about exploration or mining here is not available (Cobb, 1975, OFR 75-429). Bedrock of the area is a metasedimentary schist and marble sequence of Lower Paleozoic age (Till and others, 1986). Quaternary/Teritiary basalt flows locally cap ridges along the Hannum Creek valley.
Workings: Some small open-cut placer mine workings may be present. Hannum Creek (BN057) has been placer mined at the mouth of Collins Creek.
Age: Quaternary
Commodities (Major) - Au; (Minor) - Pb
Development Status: Undetermined.
Deposit Model: Placer Au-PGE (Cox and Singer, 1986; model 39a)
