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 (Workings): Workings / Exploration = Selected surface samples contain up to 5.43 g/tonne silver, and 99 ppm copper (Bundtzen and Laird, 1983).
Comment (Reference): Primary Reference = Bundtzen and Laird, 1983
Comment (Geology): Geologic Description = The Round occurrence consists of an iron-stained quartz-epidote stockwork in hornfels of the Late Cretaceous Kuskokwim Group flysch (Bundtzen and Laird, 1983). The occurrence is poorly exposed and mainly observed in talus and rubble crop. No surface dimensions were measured, and its extent is unknown. Selected surface samples contain up to 5.43 grams/tonne silver and 99 ppm copper (Bundtzen and Laird, 1983).
Comment (Deposit): Model Name = Polymetallic vein (Cox and Singer, 1986; model 22c).
