Unnamed (west of Kwain Bay)

The Unnamed (west of Kwain Bay) is a silver, zinc, lead, and 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): Ore Material = 'Sulfide minerals'

Comment (Reference): Primary Reference = Karl, 1992

Comment (Workings): Workings / Exploration = The occurrences were found by private exploration in the 1970s. One soil(?) sample near this contact reportedly contained detectable gold (Karl, 1992, loc. 36a-c).

Comment (Geology): Geologic Description = The country rocks at this site are recrystallized, locally semischistose, rhyolite, that is conformably overlain by massive dolomitic limestone (Berg, 1972 [I 684]). These Upper Triassic strata were regionally metamorphosed to greenschist grade in Late Cretaceous time. The occurrences, found by private exploration in the 1970s, reportedly consist of sulfide minerals at or near the rhyolite-carbonate contact. One soil(?) sample near this contact reportedly contained detectable gold (Karl, 1992, loc. 36a-c).
