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 = Jansons and others, 1984

Comment (Workings): Workings / Exploration = Site examined as part of a U.S. Bureau of Mines and U.S.G.S. mineral evaluation of the Chugach National Forest. One chip sample contained 41 ppm Zn, and 7 ppm Cu, and a grab sample contained 1.23% Zn and 0.17% Cu (Jansons and others, 1984).

Comment (Geology): Geologic Description = The country rocks at this occurrence are slate and graywacke of the Upper Cretaceous Valdez Group (Nelson and others, 1985). Jansons and others (1984) describe a 4-foot-wide shear zone in the slate and graywacke that contins a foot-wide zone of pyrite, spalerite, and malachite. One chip sample contained 41 ppm Zn, and 7 ppm Cu, and a grab sample contained 1.23% Zn and 0.17% Cu.

Comment (Exploration): Status = Inactive
