The Unnamed (lower Little Eldorado Creek in the Chatanika flats) 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): Geologic Description = Little Eldorado Creek drains the north side of Pedro Dome. Bedrock in the headwaters area consists of granodiortie on Pedro Dome and micaceous quartzite, quartz-mica schist and pelitic schist of the Fairbanks schist unit (Weber and others, 1992). These drift mines access deep aurfierous gravel in the Chatanika flats. Production figures for these drift mines have not been reported.
Comment (Workings): Workings / Exploration = Mining by drift methods only. During the winter of 1995-1996, a crew of six mined 17,000 cubic yards of high grade gravel using low profile loaders and excavators. The gravel was sluiced during the summer months of 1996 (Swainbank and others, 1997). Underground placer operations continued in 1997 (Swainbank and others, 1998).
Comment (Reference): Primary Reference = Swainbank and others, 1997
Comment (Production): Production Notes = Production figures for these drift mines have not been reported.
Comment (Deposit): Model Name = Placer gold deposit (Cox and Singer, 1986; model 39a).
Comment (Exploration): Status = Active
