The Anderson Bay is a gold, silver, molybdenum, and copper 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.

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 = Forty-two silt and soil samples were collected during reconnasissance mapping. Samples yielded up to 64 ppm molybdenum, 215 ppm copper, 1.6 ppm silver, and 0.05 ppm gold.
Comment (Reference): Primary Reference = Christie, 1974
Comment (Geology): Geologic Description = Country rock consists of amygdaloidal basic volcanic flows and pyroclastic rocks, often highly ferrigenous. Christie (1974) mentioned, but did not describe a nearby intrusive body. Strongly developed, but very local and irregularly distributed gossan bodies are present due to high amounts of disseminated pyrite in rock. Fracturing is poorly to moderately developed, no orientation was reported. Work focused on two zones, 75 ft (23 m) by 100 ft (30 m) in size that contain up to 5 percent disseminated pyrite.
Comment (Deposit): Model Name = Copper porphyry, porphyry copper-molybdenum, epithermal gold vein
Comment (Deposit): Model Number = 17, 21a, 25
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Cenozoic
