The Telaquana River 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 (Reserve-Resource): Reserves = No reserves
Comment (Production): Production Notes = No production
Comment (Workings): Workings / Exploration = Three of eight rock samples collected contained Mo (one with 3,200 ppm Mo). Nelson and others (1985) reported a weak halo of anomalous zinc concentration. No geochemical values provided.
Comment (Reference): Primary Reference = Nelson and others, 1985
Comment (Geology): Geologic Description = Sparse desseminations of molybdenite in contact zone of granodiorite and metamorphosed volcanic sedimentary rocks related to a roof pendant with marble that is heavily iron-stained and pyritized. Three of eight rock samples collected contained Mo, one sample with 3,200 ppm Mo (Nelson and others, 1985). The occurrence coincides with NW trending faults and a NE lineament. ? the granodiorite is a medium-gray, medium-grained biotite-hornblende granodiorite (Nelson and others, 1983, unit Ti16). Potassium-argon dates on biotite and hornblende from one speciman of this unit yielded ages of about 31 to 35 m.y. (Reed and Lanphere,1972; 1973). ?
Comment (Deposit): Model Name = Porphyry Mo, Low - F (Cox and Singer, 1986; model 21b)
Comment (Deposit): Other Comments = Site is in Lake Clark National Park and Preserve.
Comment (Geology): Age = Tertiary or younger. Potassium-argon dates on biotite and hornblende from one granodiorite specimen yielded ages of about 31 to 35 m.y. (Reed and Lanphere,1972; 1973).
