The Unnamed (in headwaters of Dry Canyon Creek) is a zinc, lead, and copper 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 (Workings): Workings / Exploration = No workings or exploration acitivities are known but regional stream sediment geochemical and airborne radiometric surveys may have been completed in the area.
Comment (Geology): Age = Not known; probably mid-Cretaceous or younger. K/Ar ages for the nearby Darby pluton are 88.3 +/- 1.5 and 92.8 +/- 2.6 Ma (Berry and others, 1976).
Comment (Reference): Primary Reference = Miller and Grybeck, 1973
Comment (Deposit): Model Name = Base-metal sulfide veins or replacements in metasedimentary rocks.
Comment (Geology): Geologic Description = This prospect occurs in feldspathic schist near the western contact of Darby pluton granite. Sphalerite, galena, chalcopyrite, and pyrite have been identified (Miller and Grybeck, 1973). Stream sediment samples from the two drainages flowing west from this occurrence contained anomalous amounts of Pb in one case, and Pb and Zn in the other. The Darby pluton is a mid-Cretaceous granodiorite and granite; K/Ar ages for the Darby pluton are 88.3 +/- 1.5 and 92.8 +/- 2.6 Ma (Berry and others, 1976). The country rocks to the pluton here are high-grade metasedimentary rocks of Paleozoic or Precambrian age (Till and others, 1986).
Comment (Exploration): Status = Inactive
