Fairly extensive placer mining on Hobson Creek suggests that the headwaters may contain undiscovered lode gold deposits, possibly continuations of the Breen East lodes (NM085).
Location: Hobson Creek is a west tributary to Nome River that enters Nome River about 1 mile above Willow Creek. It joins Manila Creek at the Miocene Ditch crossing in the Nome C-1 quadrangle and is auriferous from about the Miocene Ditch upstream for more than a mile to at least Wet Gulch, an eastern headwater tributary of Hobson Creek. The location used here is at the border between the C-1 and D-1 quadrangles. Hobson Creek is locality 111 of Cobb (1972 [MF-463], 1978 [OFR [78-93]).
Geology: Hobson Creek was prospected in 1900 but little gold was produced by 1908 (Collier and others, 1908, p. 181). The creek was subsequently mined by dredging from at least 1913 to 1916. The fault that hosts the Breen antimony-gold prospect (NM085) likely crosses the upper part of the creek. Bundtzen and others (1994) mapped a linear structure in Wet Gulch, and there are other faults and sheared formational contacts upstream which could have localized lode gold sources in the Hobson Creek drainage. Bedrock in the Hobson Creek drainage is a metasedimentary schist and marble sequence (Hummel, 1962 [MF 248]; Bundtzen and others, 1994).
Workings: Small-scale mechanical placer mining for gold took place after 1908. In 1913, a 2.5-cubic-foot dredge was moved onto the creek by Arctic Gold Dredging Company. The creek was considered to be rather steep for dredging (Chapin, 1914, p. 387, 390). The dredging difficulties must have been solved to some extent because the dredge was still in operation by the same company in 1916 (Mertie, 1918 [B 662-I, p. 452]).
Age: Quaternary.
Production: The creek was productive at least from 1913 to 1916.
