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 (Exploration): Status = Inactive

Comment (Deposit): Model Name = Chugach-type low-sulfide gold-quartz vein (Bliss, 1992; model 36a.1), turbidite-hosted gold vein.

Comment (Geology): Geologic Description = This occurrence consists of a 20-inch-thick quartz vein which strikes northwest and dips southwest, approximately parallel to the Bear (KD003) and Dan (KD004) veins. It crops out northeast of the Dan and cuts Cretaceous metasedimentary rock. The vein carries arsenopyrite, pyrite, galena, and gold. Acidic dikes occur in the vicinity.

Comment (Reference): Primary Reference = Becker, 1898

Comment (Deposit): Other Comments = No additional information is available since Becker's 1898 description.

Comment (Geology): Age = Cretaceous or younger

Comment (Geology): Age = Cretaceous or younger
