Pearl Creek

The Pearl 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 placer.

Comment (Workings): Workings / Exploration = Placer gold was mined along Pearl Creek from 1911 to 1914, from 1938 to 1940, and in recent years, as evidenced by the relatively fresh tailings near its confluence with Fish Creek (Chapman and Foster, 1969; Cobb, 1976 [OFR 76-662, p. 109]).

Comment (Geology): Geologic Description = Pearl Creek drains an area predominantly underlain by Cretaceous granite that has intruded the Fairbanks Schist (Newberry and others, 1996). Placer gold was mined along Pearl Creek from 1911 to 1914, from 1938 to 1940, and in recent years, as evidenced by the relatively fresh tailings near its confluence with Fish Creek (Cobb, 1976 [OFR 76-662, p. 109]). Abundant scheelite, wolframite, and native bismuth have been found in concentrates.

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

Comment (Reference): Primary Reference = Cobb, 1976 (OFR 76-662)

Comment (Production): Production Notes = Placer gold was mined, but production figures are not available.

Comment (Exploration): Status = Inactive

Comment (Deposit): Other Comments = See also Yellow Pup, FB121.
