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 (Geology): Geologic Description = At this chromite occurrence, one of several within the Halibut Bay ultramafic complex, chromite seams less than 1 inch in thickness occur in a 30 by 3-foot wide zone having an estimated depth of 8 feet. Grade was estimated to be 10 percent chromite and size to be less than 1000 tons (Foley and Barker, 1985, table 13).? the Halibut Bay ultramafic complex, consisting mostly of dunite, gabbro, pyroxenite, and peridotite, occurs within sedimentary units of the Uyak formation of Cretaceous age.
Comment (Deposit): Model Name = Podiform chromite (Cox and Singer, 1986; model 8a).
Comment (Workings): Workings / Exploration = This deposite is estimated to contain less than 1000 tons of rock grading 10 percent chromite (Foley and Barker, 1985, table 13).
Comment (Reserve-Resource): Reserves = This deposit is estimated to contain less than 1,000 tons of rock grading 10 percent chromite.
Comment (Reference): Primary Reference = Foley and Barker, 1985
Comment (Deposit): Other Comments = Site is located within Kodiak National Wildlife Refuge.
