Rock Creek

The Rock 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; the location and elevation of this area indicate that it was probably affected by Quaternary sea level fluctuations.

Comment (Geology): Geologic Description = Some small-scale mining took place as early as 1903 and between 1932 and 1934 (Cobb, 1978, OF 78-181). Bedrock is schist but the gravels include much greenstone, slate fragments, and quartz pebbles Both fine and coarse gold was recovered. The gold could have partly been reworked from coastal plain deposits (Smith, 1910). Most of Rock Creek is below 200 feet elevation. Bedrock here is part of a lower Paleozoic metasedimentary assemblage that includes a distinctive black, very fine-grained, graphitic schist in this area (Sainsbury and others, 1972 (OFR 511); Till and others, 1986).

Comment (Workings): Workings / Exploration = Small-scale open-cut placer mining operations took place locally on this creek between 1903 and 1934.

Comment (Reference): Primary Reference = Smith, 1910

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

Comment (Exploration): Status = Probably inactive
