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 (Workings): Workings / Exploration = None reported.

Comment (Reference): Primary Reference = Martin and others, 1915

Comment (Geology): Geologic Description = A few small apparently barren quartz veins and auriferous granite dikes cut slate and graywacke of the Cretaceous Valdez Group (Cobb, 1979, OFR 80-87). A sample of granite assayed $1.80 gold per ton, at $20.67 per ounce gold (Grant and Higgins, 1910).

Comment (Deposit): Other Comments = This prospect is within Kenai Fjords National Park; the area is now closed to mineral entry.

Comment (Exploration): Status = Inactive

Comment (Deposit): Model Name = Low-sulfide, Au-quartz vein (Cox and Singer, 1986; model 36a)

Comment (Geology): Age = Cretaceous or younger; veins cut and dike cuts Cretaceous graywacke.
