The Ebner Mine is a gold and 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.

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 (Commodity): UNCERTAIN IF PB WAS PRODUCED; PB WAS AN IMPORTANT BY-PRODUCT FOR ALASKA-JUNEAU MINES
Comment (Development): STAKED 1880; 10-STAMP MILL INSTALLED 1888; MINED UNTIL 1907; ADIT BEGAN IN 1912 TO UNDERCUT ORE PROVED DISCOURAGING; ALL OPERATIONS HALTED 1920; OPTIONED BY ALASKA-JUNEAU GOLD MINING CO. IN 1925; OPERATED ON A ROYALTY BASIS 1925-1944; 15 PATENTED LODE CLAIMS, IN PART DUPLICATES WITH A.J. CLAIMS
Comment (Workings): DEVELOPMENT AS OF 1906: 4000 FT OF UNDERGROUND WORKINGS AND SEVERAL OPEN PITS; LARGE SCALE DEVELOPMENT BETWEEN 1912-1920 ADDED SEVERAL THOUSAND FT MORE; CONNECTED TO ALASKA-JUNEAU MINE IN 1925; WORKINGS REPORTED OPEN IN 1985
Comment (Deposit): NORTHERN EXTENSION OF ALASKA-JUNEAU LODE SYSTEM; ZONE 800-1500 FT WIDE CONTAINS NUMEROUS QUARTZ VEINS 1-2 FT THICK AND STRINGERS IN METAMORPHOSED SLATE AND THREE SILL-LIKE AMPHIBOLITE BODIES; ORE ASSAY BOUNDED; MINED AREA 60-90 FT WIDE, 200-300 FT LONG AND 300-500 FT VERICAL EXTENT; VEINS LARGER AND MORE NUMEROUS IN AMPHIBOLITE, ESPECIALLY NEAR CONTACT WITH SLATE, PYRRHOTITE IS PRINCIPAL SULFIDE
