The Unnamed (Adams Inlet) 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 (Workings): Workings / Exploration = Ten claims reported in 1912 (Kimball and others, 1978, p. C351); there are no obvious workings.
Comment (Deposit): Model Name = Tactite or skarn molybdenum occurrence.
Comment (Deposit): Other Comments = the site is in Glacier Bay National Park and Preserve.
Comment (Geology): Geologic Description = Granite of Cretaceous age forms a batholithic mass that crops out on Point George and extends northerly to the Klotz Hills. Another granitic intrusion, about 1 mile across, occurs on the north side of Adams Inlet 1 mile east of the granite exposed on Point George. The two granitic intrusives are separated by volcanic and sedimentary rocks of Devonian and Silurian age (Brew and others, 1978, pl. 1A).? Buddington and Chapin (1929, p.330) reported molybdenite as coatings on fracture surfaces in metamorphic rocks, mainly hornfels and tactite, on the north side of Adams Inlet. The molybdenite occurrence is inferred to be in the belt of sedimentary and volcanic rocks that separates the major granitic intrusion exposed on Point George from the smaller mass exposed in Adams Inlet about two miles east of Point George.
Comment (Reference): Primary Reference = Buddington and Chapin, 1929
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Cretaceous or younger.
