Unnamed (near Porcupine Dome)

The Unnamed (near Porcupine Dome) 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 (Workings): Workings / Exploration = Surface sampling only.

Comment (Geology): Geologic Description = Quartz veins that cut metamorphic rocks carry Au, Ag and cassiterite (Cobb, 1976, p. 53, [OFR 76-633]). There are no known granitic rocks in the area. A sample of iron- stained quartzite containing a small quartz vein carrying arsenopyrite(?) had 3.0 ppm Au, 1.0 ppm Ag. Nearby samples are anomalous in tin (W.D. Menzie, USGS 1982-83 field notes; Foster and others, 1984).

Comment (Reference): Primary Reference = Foster and others, 1984.

Comment (Exploration): Status = Inactive
