The Schaefer is a silver 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 = High-grade silver mineralization in a shear zone with quartz.
Comment (Deposit): Other Comments = the prospect was staked in 1912 as the Eugenia claim by M.A. Schaefer (Times Publishing Company, 1912).
Comment (Workings): Workings / Exploration = By late 1912, a 30-foot shaft had been sunk on a 2.5-foot-wide shear zone which assayed 26 ounces of silver per ton. Smith (1913, B 525) indicated the Schaefer prospect consisted of a flat-lying, quartz-rich zone along which a 150 foot adit was driven by 1912. The adit trends N 5 E in highly oxidized and weathered schist. It is believed the Schaefer adit was being driven to access the high grade silver mineralization encountered in the 30-foot shaft.
Comment (Reference): Primary Reference = Smith, 1913 (B 525)
