Big Creek

The Big Creek is a lead and zinc 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 = Active?

Comment (Deposit): Other Comments = See also Ladue prospect (TC012).

Comment (Geology): Geologic Description = The Big Creek prospect is in an area of possible stratiform sulfide deposits. It consists of galena, sphalerite and iron sulfides disseminated in quartz-mica schist of Paleozoic and/or Precambrian age (Eberlein and others, 1977, p. 101). The regional geology around the prospect consists of amphibolite-grade quartz-mica schist that is Precambrian to Paleozoic in age (Foster, 1970). High copper anomalies were found in soil samples collected during the early 1970's, although no primary mineralization was found on the surface (David Hedderly-Smith, oral communication, 1998).

Comment (Workings): Workings / Exploration = Surface exploration and soil sampling conducted in the 1970's. There probably has been more recent exploration in the area.

Comment (Reference): Primary Reference = Eberlein and others, 1977

Comment (Deposit): Model Name = Stratiform Pb-Zn volcanogenic deposit?
