The Mt. Eielson Prospects is a lead, silver, 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.

Land Status
Land ownership: National Park
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comment (Development): USBM EXPLORATION IN 1943, ORE DID NOT RESPOND WELL IN FLOTATION TESTS, RESULTS OF SAMPLING AND BENEFICIATION TESTS IN USBM RI 4121, P. 5-13
Comment (Deposit): SULFIDES OCCUR AS REPLACEMENTS OF LIMESTONE BEDS, DISSEMINATED IN LIMESTONE AND LESS COMMONLY AS VEIN FILLINGS IN GRANODIORITE; IN BROAD BELT AROUND CONTACT WITH TERTIARY PLUTON
Comment (Workings): SEVERAL SHORT ADITS, PROSPECT PITS AND OPEN CUTS
Comment (Geology): PALEOZOIC CALCAREOUS SEDIMENTS INTIMATELY INTRUDED BY LARGE TERTIARY GRANODIORITE PLUTON AND NUMEROUS DIKES AND SILLS EMANATING FROM IT PRODUCED A BROAD BAND OF MINERALIZATION ALONG CONTACT; MINERALIZATION OCCURRED SELECTIVELY ALONG LIMESTONE BEDS AND IN TWO STAGES: 1) EPIDOTIZATION AND 2.) REPLACEMENT OF EPIDOTE MINERALS BY SULPHIDES.
