North Star

The North Star is a silver, gold, and 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 (Reference): Primary Reference = Buddington, 1929

Comment (Deposit): Model Name = Polymetallic veins

Comment (Deposit): Other Comments = the name Bevacque (Bervaqua) has been associated with this occurrence (Buddington, 1929).? Elliott and Koch (1981, p. 13, loc. 43) list silver and gold as queried commodities at the North Star prospect, but do not mention them in their description of the deposit. Nor is silver or gold mentioned in any of the earlier published descriptions of the prospect.

Comment (Geology): Geologic Description = The country rocks in the area of the North Star occurrence are pelitic metasedimentary and subordinate andesitic metavolcanic strata of the Jurassic or older Mesozoic Hazelton Group, which are underlain and locally intruded by the Triassic Texas Creek Granodiorite (Smith, 1977; Koch, 1996).? Buddington (1929, p. 110) describes the deposit as a quartz fissure vein in graywacke about 150 feet from the contact of the Texas Creek Granodiorite. The vein is 1-2.5 feet thick and exposed in outcrop for 50 feet. Locally the vein contains masses of galena and a little pyrite.

Comment (Exploration): Status = Inactive
