The Normandy is a copper, lead, and zinc 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 (Exploration): Status = Inactive
Comment (Deposit): Model Name = Polymetallic veins (Cox and Singer, 1986; model 22c)
Comment (Deposit): Other Comments = This prospect is located on land patented by, or interim-conveyed to, the Aleut Corporation.
Comment (Geology): Geologic Description = The Normandy prospect, discovered in 1981, consists of a northeast-striking 15- to 40-foot-wide zone of quartz veins, silicified andesite, and sulfides, chielfly pyrite, chalcopyrite, galena, and sphalerite. The andesite is part of the late Eocene to early Oligocene Popof volcanic rocks (Wilson and others, 1995). The mineralization is exposed on the sea cliffs and extends at least 300 feet into the ocean. It is traceable on land as an airphoto lineament. VLF-EM surveys indicate anomalies on strike at 600 and 3,000 feet from the beach. Deep soil and flooding have prevented trenching from exposing the deposit. Assays of rock samples show up to 0.3 percent copper, 3.7 percent lead, 9.4 percent zinc, 2.6 ppm gold, and 214 ppm silver (Peterson and others, 1982). Battle Mountain Exploration Company examined the site in 1986. A grab sample collected at that time contained 1.71 ppm gold (Pilcher, 1986).
Comment (Geology): Age = Eocene or younger.
Comment (Reference): Primary Reference = Peterson and others, 1982
Comment (Workings): Workings / Exploration = Resource Associates of Alaska and UNC Teton Exploration Drilling Company collected 27 rock samples, conducted VLF-EM surveys, and cut several trenches that did not expose the deposit. Rock samples contained as much as 0.3 percent copper, 3.7 percent lead, 9.4 percent zinc, 2.6 ppm gold, and 214 ppm silver. Battle Mountain Exploration Company examined the site in 1986. A grab sample collected at that time contained 1.71 ppm gold.
