Unnamed (northwest of the mouth of Quartz Creek)

The Unnamed (northwest of the mouth of Quartz Creek) is a copper 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 (Deposit): Model Name = Quartz-sulfide (sulfosalt) vein in metamorphic rocks.

Comment (Geology): Geologic Description = A quartz-sulfide (sulfosalt) vein several feet thick was reported by Collier and others (1908, p. 215) to be exposed on the bluffs above Norton Sound a short distance west of Quartz Creek. The vein was concordant to schistosity at a contact between chloritic and graphitic schist layers. Assays reported only trace amounts of gold and silver. The sulfide or sulfosalt mineral is described only as gray copper, most probably tennantite. The vein was lenticular and reportedly 'thinned rapidly' (Collier and others, 1908).

Comment (Geology): Age = Because the vein is concordant to metamorphic foliation, it could be older than mid-Cretaceous, but a younger age is also possible.

Comment (Reference): Primary Reference = Collier and others, 1908

Comment (Workings): Workings / Exploration = Prospecting activity occurred in the area shortly after the discovery of gold at Nome in 1898. The vein was discovered about 1903 or earlier.

Comment (Exploration): Status = Probably inactive
