The Unnamed is a molybdenum 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 (Reference): Primary Reference = Richter, 1963
Comment (Workings): Workings / Exploration = A bench cut and a short adit were opened. Analysis of channel samples showed up to 0.1% Mo and Zn (Richter, 1963).
Comment (Geology): Geologic Description = Host rock is quartz monzonite of Cretaceous or Tertiary age. Silicified shear zones in quartz monzonite contain lenses, vugs, and masses of molybdenite crystals and other sulfides. Molybdenite mineralization appears related to quartz monzonite.
Comment (Deposit): Model Name = Porphyry Cu-Mo (Cox and Singer, 1986; model 21a)
Comment (Deposit): Other Comments = Further exploration at this locality may be justified but would require heavy equipment or drilling due to poor surface exposure.
Comment (Geology): Age = Cretaceous or Tertiary
