The Eagan is a tungsten 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 = Open cuts and several small trenches expose the dikes (Byers, 1957).
Comment (Exploration): Status = Inactive
Comment (Geology): Geologic Description = Scheelite occurs as sparsely disseminated grains in thin (less than 6 inches) pegmatite dikes intruding granodiortie. The dikes are related to a porphyritic granite nearby (Byers, 1957, p. 206).
Comment (Deposit): Model Name = Quartz-scheelite veins.
Comment (Reference): Primary Reference = Byers, 1957
