The Unnamed (west of Beaver Creek) is a silver, zinc, and lead 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 (Deposit): Model Name = Skarn ? (Cox and Singer, 1986; model 18)

Comment (Geology): Geologic Description = This deposit is associated with skarns in medium-grade metamorphic rocks, irregular quartz veins or segregations containing galena and sphalerite. The deposit crops out in an area of at least 10 x 40 feet. The deposit may be related to a small granite pluton nearby. Samples from surface trenching contained 2800 ppm Ag and 5000 ppm Zn (Garland and others, 1975, DGGS OFR 67). Other analysis of massive galena indicates up to 1000 ppm Ag and 700 ppm Sb (Grybeck and Nelson, 1981). The deposit was staked in about 1976; work aparently was limited to surface trenching.

Comment (Exploration): Status = Active?

Comment (Reference): Primary Reference = Garland and others, 1975 (ADGGS OFR 67)
