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 = Jansons and others, 1984
Comment (Geology): Geologic Description = Quartz float contains pyrite, arsenopyrite, and chalcopyrite. A float sample contained no detectable gold and 0.03 oz/ton Ag. Bedrock in the vicinity is the Late Cretaceous metasedimentary rocks of the Valdez Group. A minor amount of placer gold present (Jansons and others, 1984).
Comment (Workings): Workings / Exploration = Quartz float sample contained no detectable gold and 0.03 oz/ton Ag. Placer gold was present in minor amounts. Jansons and others (1984) reported low mineral development potential.
Comment (Deposit): Model Name = Placer Au (Cox and Singer, 1986; model 39a)
Comment (Production): Production Notes = No production reported.
