The Unnamed (Don Miller Hills area) is a zinc 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 (Exploration): Status = Inactive
Comment (Geology): Age = the occurrences are considered to be Eocene to Miocene based on the age of the host rocks.
Comment (Reference): Primary Reference = Goldfarb and others, 1992
Comment (Deposit): Other Comments = This and other geologically similar areas in the Cordova quadrangle warrant further investigation (Nelson and others, 1994). Chugach Alaska Corporation, Anchorage, Alaska has control of these lands.
Comment (Workings): Workings / Exploration = None, however, investigations of similar geochemical anomalies to the south on Kayak Island (Pickthorn and others, 1985) failed to find any outcrops containing minerals that could be the source of the anomalous metal values in the geochemical samples (Goldfarb and others, 1992). Heavy mineral concentrates contain abundant barite, pyrite, and sphalerite. Analyses of concentrates yielded values of up to 5000 ppm Ba, >2% Zn, and 10%-30% Fe. Anomalous values of Ag, Cu, Mo, and Pb were also detected (Goldfarb and others, 1992).
Comment (Deposit): Model Name = Possibly sedimentary-exhalative Pb-Zn (Cox and Singer, 1986; model 31a)
Comment (Geology): Geologic Description = These occurrences consist of anomalous metal values in geochemical samples from drainages in the area. The metals are thought to come from organic-rich shales in continental clastic rocks of Eocene to Miocene age (Goldfarb and others, 1992), intercalated with marine mafic volcanic rocks in the Poule Creek Formation (Winkler and Plafker, 1991). Heavy mineral concentrates contain abundant barite, pyrite, and sphalerite. Analyses of concentrates yielded values of up to 5000 ppm Ba, >2% Zn, and 10%-30% Fe. Anomalous values of Ag, Cu, Mo, and Pb were also detected (Goldfarb and others, 1992).
