The Tiflighak Bay is a lead 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 = None

Comment (Exploration): Status = Inactive

Comment (Reference): Primary Reference = Cobb, 1980 (OFR 80-909)

Comment (Geology): Geologic Description = Galena in small quartz veins in Cretaceous quartz monzonite exposed near top of cliff (oral communication, Bela Csejtey, Jr. May 24, 1972; as cited by Cobb, 1972; 1980).??The Sevuokuk pluton in the vicinity of this site is biotite quartz monzonite (Csejtey, Patton and Miller, 1971) for which one K/Ar determination indicates an age of 108 +/- 3.2 Ma (Patton and Csejtey, 1980).

Comment (Deposit): Model Name = Vein in granitic rock. Deposit model 22c (?); polymetallic veins

Comment (Geology): Age = Not known; assumed to be mid -Cretaceous, the age of the associated granitic rocks.
