Wolverine

The Wolverine 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.

Alterations

Alteration Type: L
Alteration Text: Wall-rock alteration within a few inches of the veins is intense, but seldom extends more than 10 to 12 inches beyond the quartz filling. Sericitization and carbonate alteration predominate, but there is some pyritization and in the outer parts of the alteration zone chloritization is present (Ray, 1954).

Comments

Comment (Deposit): Model Name = Low-sulfide Au-quartz veins (Cox and Singer, 1986; model 36a)

Comment (Geology): Geologic Description = Tertiary and Late Cretaceous tonalite is cut by a granitic dike and quartz veins. Quartz veins, up to 16 inches wide, and narrow quartz stringers are generally in east-trending, north-dipping shear zones. Four faults and sixteen shear zones have been exposed in workings. Pyrite, arsenopyrite, and chalcopyrite reported in quartz vein, but these sulfides make up less than 2 percent of veins. Up to 3.6 oz/ton Au, but commonly less than 0.5 oz/ton Au (Jasper, 1962).? the tonalite is part of the Willow Creek Pluton, a zoned pluton. The outer part consists of hornblende quartz diorite and lesser hornblende tonalite; the core consists of hornblende-biotite granodiorite, and lesser hornblende-biotite quartz monzodiorite and biotite quartz monzonite. Wall-rock alteration within a few inches of the veins is intense, but seldom extends more than 10 to 12 inches beyond the quartz filling. Sericitization and carbonate alteration predominate, but there is some pyritization and in the outer parts of the alteration zone chloritization is present (Ray, 1954).

Comment (Exploration): Status = Inactive

Comment (Geology): Age = Late Cretaceous or younger; the veins cut the Late Cretaceous Willow Creek Pluton.

Comment (Workings): Workings / Exploration = Explored by 474 ft of underground workings; 323 ft of crosscuts, 56 ft of drifts, 75 ft raise, and 20 ft winze to the surface were reported. In additon, surface cuts were present. Gold values were up to 3.6 oz/ton Au, but commonly less than 0.5 oz/ton Au (Jasper, 1962).

Comment (Production): Production Notes = No known production.

Comment (Reference): Primary Reference = Jasper, 1962

Comment (Deposit): Other Comments = the productive quartz veins of the district are restricted to those trending east/west and dipping north in major shear zones (Jasper, 1962).
