North Star Extension

The North Star Extension is a gold 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 = This property was developed by tunnels and shafts. In 1909 the Central Star shaft was 65 feet deep with 200 feet of tunnel (Prindle, 1910).

Comment (Reference): Primary Reference = Prindle, 1910

Comment (Deposit): Model Name = Gold-bearing quartz porphyry dike.

Comment (Geology): Geologic Description = Gold occurs in a 20-foot-wide quartz porphyry dike that strikes N 30 W and dips 45 SW. This dike was exposed by a tunnel driven 50 feet through schist. The dump material on the Central Star shaft is composed mainly of schist but contains some fragments of quartz porphyry (Hill, 1933, p. 118). In 1909, this shaft was 65 feet deep (Prindle, 1910).

Comment (Production): Production Notes = In 1916, some ore was milled on the ground in a home-made 1-stamp mill driven by a 6-horsepower gasoline engine (Hill, 1933, p. 118).

Comment (Exploration): Status = Inactive
