Auburn Creek (Ravine)

The Auburn Creek (Ravine) 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 (Exploration): Status = Probably inactive

Comment (Reference): Primary Reference = Smith, 1909

Comment (Workings): Workings / Exploration = Small-scale mining occurred here in 1908.

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

Comment (Geology): Geologic Description = Smith (1909) reports that the gravels of Auburn Creek carry gold upstream to headwater reaches but Sainsbury and others (1972) show the location of placer workings to be localized about 0.5 miles upstream from the mouth. The gold was coarse, on clay layers rather than bedrock, and had a fineness of 945. Heavy mineral concentrates contained garnet, ilmenite, magnetite, and cinnabar (Smith, 1909). Marble bedrock contained underground channels (karst ?) that captured surface water and solution-etched boulders were present in stream gravels. Bedrock in the area is part of a lower Paleozoic metasedimentary assemblage (Till and others, 1986); marble in this assemblage crops out preferentially along the east side of the Auburn Creek valley.

Comment (Geology): Age = Quaternary.
