The Kav is a silver, copper, and antimony 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 = Degenhart and others, 1978

Comment (Workings): Workings / Exploration = Two samples representative of mineralized dolomite breccia contained 18.6% Cu over 36 ft. (12 m) length, and 33.8% Cu over 50 ft. (17 m) length. One 4 to 6 in. (8 cm to 12 cm) wide quartz vein assayed 6.2% Cu, 0.62% Zn, 4.9 oz/ton (152g/ton) Ag, and 3.2% Sb. Another 40 ft. (13 m) chip sample across a stringer zone assayed 0.8% Cu, 0.48 oz/ton (15g/ton) Ag (Degenhart and others, 1978, p. 351-371).

Comment (Geology): Geologic Description = Four occurrences of Cu-Ag mineralization over 0.15 sq. mi. (200 m sq.) area. Most interesting occurrence is a fan-shaped area of mineralized talus ranging from 5 ft. to 10 ft. (1.3 m to 3 m) wide over a slope distance of 300 ft. (100 m) that consists of dolomite breccia containing masses of tetrahedrite, tennantite, chalcopyrite, malachite and azurite, mixed with fragments of quartz-vein material containing chalcopyrite. Other three occurrences are quartz veins generally 0.5 to 6 in. (1 cm to 12 cm) wide (one vein 1.5 ft. (0.3 m) wide) having strike lengths up to 75 ft. (15 m), and quartz stringer zones 40 ft. to 100 ft. (10.5 m to 30 m) wide, carrying tetrahedrite, chalcopyrite and malachite. Host rock is brecciated dolomite overlain by limestone and underlain by limestone, marble, and a sequence of phyllites; dolomite breccia forms prominent rust-colored hills (Degenhart and others, 1978, p.351-371)

Comment (Deposit): Other Comments = Three minor occurrences of malachite are present along the north slope of the mountain immediately southwest of Kav occurrence.?All occurrences are located within Noatak National Preserve.
