The Swan 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 (Geology): Age = Tertiary.

Comment (Reference): Primary Reference = Ellis, 1988; Wilson and others, 1995

Comment (Workings): Workings / Exploration = Battle Mountain Exploration Company examined the area in 1988 and collected 21 rock samples for analysis. The samples were anomalous in arsenic, but contained only a trace of gold. Pan samples contained as much as 0.36 ppm gold (Ellis, 1988).

Comment (Geology): Geologic Description = This occurrence consists of a 1100- by 600-foot area containing scattered quartz veins in argillically and locally propylitically altered tuff (Ellis, 1988). The volcanic rock is Tertiary in age (Wilson and others, 1995). Chalcedonic quartz occurs in veins 0.5 to 6 inches wide containing up to 5 percent disseminated pyrite and scattered pyrite boxworks. Rock samples were anomalous in arsenic, but only a trace gold was detected. Pan samples contained as much as 0.36 ppm gold (Ellis, 1988).

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

Comment (Deposit): Model Name = Epithermal gold veins

Comment (Exploration): Status = Inactive
