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 (Workings): Workings / Exploration = Analyses of rock samples from south valley wall of upper Granite Creek yielded 0.2 ppm Au, 0.8 ppm Ag, >1.0% Zn, >1.0% Cu (Clautice and others, 1990).

Comment (Reference): Primary Reference = Clautice and others, 1990

Comment (Geology): Geologic Description = Analyses of mineralized samples from gossans and clay-rich shear zones in tuffs and flows of the Lower Jurassic Talkeetna Formation.

Comment (Deposit): Model Name = Polymetallic vein or porphyry Cu-Au? (Cox and Singer, 1986; model 22c or 20c?)

Comment (Exploration): Status = Inactive
