Hobson Creek

The Hobson Creek is a gold mine located in Alaska.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Geology): Age = Quaternary.

Comment (Geology): Geologic Description = 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).

Comment (Reference): Primary Reference = Cobb, 1978 (OFR 78-93)

Comment (Workings): Workings / Exploration = 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]).

Comment (Production): Production Notes = The creek was productive at least from 1913 to 1916.

Comment (Deposit): Other Comments = 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).

Comment (Exploration): Status = Inactive

Comment (Deposit): Model Name = Placer Au (Cox and Singer, 1986; model 39a).
