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 = Peterson and others, 1982

Comment (Geology): Age = Eocene or younger.

Comment (Workings): Workings / Exploration = UNC Teton Exploration Drilling Company sampled the occurrence in 1982. Samples contained as much as 0.02 ppm gold, 15 ppm silver, 720 ppm zinc, 510 ppm arsenic, and 5 ppm mercury.

Comment (Geology): Geologic Description = This occurrence consists of several knobs of andesite breccia in an area 100 by 1,000 feet. The breccias contain pyrite, chalcedony, jasper, and zeolite. Samples of the breccia contained as much as 0.02 ppm gold, 15 ppm silver, 720 ppm zinc, 510 ppm arsenic, and 5 ppm mercury (Peterson and others, 1982). The andesite is part of the late Eocene to early Oligocene Popof volcanic rocks (Wilson and others, 1995).

Comment (Deposit): Other Comments = The site is located on land patented by, or interim-conveyed to, the Aleut Corporation.

Comment (Deposit): Model Name = Epithermal gold vein

Comment (Exploration): Status = Inactive
