The Unnamed is a molybdenum and gold 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 = Nelson and others, 1986
Comment (Reserve-Resource): Reserves = No reserves
Comment (Workings): Workings / Exploration = Unknown
Comment (Exploration): Status = Inactive
Comment (Production): Production Notes = No production
Comment (Geology): Geologic Description = Molybdenum claim in rhyolite and associated granite bodies (Nelson and others, 1983; unit Tv). Unit Tv includes rhyolitic breccia, ash-flow tuff, flows, and intrusive rocks and subordinate mafic to intermediate flows. MacKevett and Holloway (1977) speculated that the claim is located in an area of quartz veining. Potassium-argon ages for Unit Tv range from 56.2 to 62.7 m.y. (Eakins and others, 1978).
Comment (Deposit): Other Comments = Site is in Lake Clark National Park and Preserve.
Comment (Deposit): Model Name = Porphyry Mo, low - F (Cox and Singer, 1986; model 21b)
Comment (Geology): Age = Tertiary or younger; potassium-argon ages for the host rock range from 56.2 to 62.7 m.y. (Eakins and others, 1978).
Comment (Geology): Age = Chron age is for Host Rock.
