The Telaquana Pass 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 (Production): Production Notes = No production
Comment (Reference): Primary Reference = Nelson and others, 1985
Comment (Reserve-Resource): Reserves = No reserves
Comment (Workings): Workings / Exploration = Resource Associates of Alaska (1976) reported a sample that yielded 2,200 ppm Mo.
Comment (Geology): Geologic Description = Resource Associates of Alaska (1976) reported molybdenite in veinlets of quartz and pyrite in quartz diorite near contact with granite. Large area of iron-staining due to weathering of pyrite veins and disseminated pyrite and pyrrhotite. MacKevett and Holloway (1977) describe the occurrence as being hosted in a composite Tertiary granitic pluton. Nelson and others (1983, unit Ti17) describe the rocks as uniformly grayish-white, coarse-grained biotite granite with lesser biotite-hornblende granite and granodiorite. There is some magnetite in quartz-magnetite veins. Adjacent granite is not mineralized. Resource Associates of Alaska (1976) reported a sample that yielded 2,200 ppm Mo. Nelson and others (1985) could not confirm the molybdenite occurrence. ? the age of the granite host rock is Tertiary. Potassium-argon dates on samples from this granitic body range from 35 to 41 m.y. (Reed and Lanphere,1972; 1973). ? ?
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 = Granite host is Tertiary. Potassium-argon dates on samples from this granitic body range from 35 to 41 m.y. (Reed and Lanphere,1972; 1973).
Comment (Geology): Age = Host rock is Tertiary.
