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 (Reference): Primary Reference = Cobb, 1978 (OFR 78-1062)
Comment (Geology): Geologic Description = French Gulch drains the Tertiary Nenana Gravel, which locally contains gold paleoplacers. The source of the placer gold in French Gulch probably results from reworking the Nenana Gravel.
Comment (Exploration): Status = Inactive
Comment (Deposit): Model Name = Placer Au (Cox and Singer, 1986; model 39a)
Comment (Production): Production Notes = One of the limiting factors for mining here was the lack of water.
Comment (Workings): Workings / Exploration = Surface only.
Comment (Geology): Age = Quaternary.
