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 = A written communication from F. H. Waskey (1935), probably to J. B. Mertie Jr., reported that placer gold had been identified on Keefer Creek (Cobb, 1972 [MF 384]). Keefer Creek is an approximately 7-mile-long south tributary to the Mulchatna River. The Mulchatna River approximately coincides with a major structural boundary between mid-Cretaceous Kuskowim Group clastic rocks to the west and Mesozoic sedimentary and igneous rocks to the east (Decker and others, 1994).
Comment (Deposit): Model Name = Placer Au-PGE (Cox and Singer, 1986; model 39a)
