The Eagan and Eagan is a 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 (Workings): Workings / Exploration = By 1931, several hand trenches exposed four or five quartz-bearing shear zones approximately 100 feet apart (Hill, 1933). In 1938, two 15-foot shafts were sunk on the prospect but no information about these shafts is known (Reed, 1939).
Comment (Reference): Primary Reference = Hill, 1933
Comment (Geology): Geologic Description = By 1931, several hand trenches exposed four or five quartz-bearing shear zones approximately 100 feet apart (Hill, 1933). The shear zones trend N 40 W and dip 45-60 SW the prospect is hosted in flat-lying biotite schist. One shear consists of an 8-foot-thick zone of mixed schist and quartz although most of quartz-rich portions are 1 to 2 feet wide. A 20-inch-wide quartz shear zone contained 0.36 ounces of gold per ton. In 1938, two 15-foot shafts were sunk on the prospect but no information about these shafts is known (Reed, 1939). Placer gold was produced from Kokomo Creek below the Egan prospect but its relationship to mineralization on the Eagan prospect is unknown (Burand, 1968).
Comment (Deposit): Model Name = Gold-quartz vein.
Comment (Deposit): Other Comments = This prospect was discovered and staked by J.J. Egan and Dan Egan about 1930 (Hill, 1933).
Comment (Exploration): Status = Inactive
