Hummel

The Hummel is a zinc, copper, lead, silver, and 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 (Reference): Primary Reference = Buddington, 1929

Comment (Workings): Workings / Exploration = Minor surface exploration.? An early assay of a nearly pure sample of the sphalerite showed 22.78 oz of Ag and 0.02 oz of Au per ton.

Comment (Exploration): Status = Inactive

Comment (Deposit): Model Name = Polymetallic veins

Comment (Geology): Geologic Description = The country rocks in the area of the Hummel prospect include pelitic metasedimentary and subordinate andesitic metavolcanic strata of the Jurassic or older Mesozoic Hazelton Group; the Triassic Texas Creek Granodiorite, which underlies and locally intrudes the Hazelton; and the Eocene Hyder Quartz Monzonite, which intrudes both the Hazelton and Texas Creek rocks (Smith, 1977; Koch, 1996).? the deposit (Buddington, 1929, p. 98) consists of stringers of sulfides and quartz in a shear zone that cuts argillite and slate. The zone is at least 2 feet thick and contains up to 6 inches of solid sulfides along the hanging wall. The sulfides include sphalerite, galena, pyrite, chalcopyrite, and minor tetrahedrite. A nearly pure sample of the sphalerite contained 22.8 oz of Ag and 0.02 oz of Au per ton.
