Unnamed (north of Kisarilik Lake)

The Unnamed (north of Kisarilik Lake) 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 = Reconnaissance surface observation and geochemical sampling has occurred at this site.

Comment (Deposit): Model Name = Polymetallic veins (Cox and Singer, 1986; model 22c).

Comment (Geology): Geologic Description = Pyrite-bearing rhyolite dikes and sulfide-bearing quartz veins cut Jurassic volcanic and sedimentary rocks on the ridges north of Kisarilik Lake (Frost, 1990; Box and others, 1993). Rock samples from this large, red-weathering area, contain up to 0.41 ppm Au, 1.5 ppm Ag, 7,000 ppm As, and 100 ppm Sb (Frost, 1990; Frost and others, 1992).

Comment (Geology): Age = Late Cretaceous or Early Tertiary ; postdates Jurassic host rocks and is probably related to the Upper Cretaceous/Lower Tertiary suite of intermediate to felsic intrusive rocks in the region (Box and others, 1993).

Comment (Reference): Primary Reference = Frost, 1990

Comment (Exploration): Status = Probably inactive
