Unnamed (northeast of Chauik Mountain)

The Unnamed (northeast of Chauik Mountain) is a zinc, lead, and silver 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 (Geology): Age = Cretaceous; this occurrence is probably related to emplacement of the Pargon pluton which is assumed to be Cretaceous in age.

Comment (Reference): Primary Reference = Hudson and Wyman, 1983

Comment (Workings): Workings / Exploration = No workings are present and only reconnaissance sampling has been done.

Comment (Geology): Geologic Description = This occurrence is a thin gossan zone, about 10 inches wide, that trends across the ridge crest. It may be along a small fault. A grab sample contained 12.4 % Pb, 3.45 ounces/ton Ag, 6,250 ppm Zn, and less than 5 ppb Au (Hudson and Wyman, 1983). This base metal occurrence, and several others in this part of the Bendeleben A-4 quadrangle, are in high grade metasedimentary rocks that are structurally above or peripheral to the crosscutting Pargon pluton. The Pargon pluton is mostly granodiorite and assumed to be Cretaceous in age (Till and others, 1986). It was emplaced at shallower depths than the more deep-seated Bendeleben pluton to the east.

Comment (Deposit): Model Name = Galena-bearing vein in high grade metasedimentary rocks

Comment (Exploration): Status = Inactive
