The Unnamed (near 'Rock Creek') is a antimony 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 (Reference): Primary Reference = Joesting, 1943
Comment (Workings): Workings / Exploration = Surface exploration only.
Comment (Deposit): Model Name = Simple Sb (Cox and Singer, 1986; model 27d)
Comment (Exploration): Status = Inactive
Comment (Geology): Geologic Description = Limited information suggests that this deposit consists of one or more quartz-antimony veins near the contact between the Keevy Peak Formation to the north and Birch Creek Schist to the south (Wilson and others, 1998). The veins may be related to Upper Cretaceous and Lower Tertiary intrusive rocks that cut the metasedimentary rocks nearby.
Comment (Geology): Age = Late Cretaceous or younger, assuming that the deposit is related to the intrusive rocks.
