The Milroy Creek is a lead and silver mine located in Alaska.
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 (Geology): Age = Quaternary
Comment (Reference): Primary Reference = Anderson, 1947
Comment (Geology): Geologic Description = Anderson (1947, p. 31) reports that heavy mineral concentrates from Milroy Creek gravels are similar to those from Cunningham Creek (BN113) which contain galena, lead carbonates, and pyromorphite. The Harrys Creek (BN055) and Hannum Creek (BN056) galena-bearing lode deposits are sources of lead minerals in gravels downstream from them. The presence of placer gold has not been specifically reported (Cobb, 1981; OFR 81-363A).
Comment (Deposit): Model Name = Placer Au-PGE ? (Cox and Singer, 1986; model 39a)
Comment (Exploration): Status = Probably inactive
