Bechevin Bay

The Bechevin Bay 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.

Comments

Comment (Exploration): Status = Inactive

Comment (Workings): Workings / Exploration = Brief reconnaissance geologic mapping and geochemical sampling reported by Christie (1974). Geochemical results showed copper typically less than 30 ppm and molybdenum less than 5 ppm; silver ranged from 0.9 to 1.6 ppm and gold was generally less than 0.01 ppm one sample yielded 0.02 ppm.

Comment (Geology): Geologic Description = Christie (1974) reported brief reconnaissance mapping of a color anomaly 2,000 by 3,000 ft, (600 by 900 m) covering a variety of volcanic rocks. The color anomaly is apparently due entirely to pervasive pyrite disseminated in all rock types. 99 percent of the pyrite is disseminated at concentrations up to 15 percent of the rock, and only rarely is it seen in fractures.

Comment (Reference): Primary Reference = Christie, 1974

Comment (Deposit): Model Name = Epithermal gold vein

Comment (Deposit): Other Comments = Chrisite (1974) typically does not mention quartz veins in his descriptions. If they are not present at this occurrence, their absence probably is significant with respect to potential for epithermal gold vein mineralization.

Comment (Geology): Age = Miocene or younger
