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): IN 1961 6 DRILLHOLES (TOTALING 900 FT IN LENGTH) WE RE DRILLED IN AN EFFORT TO DETERMINE URANIUM CONTENT; NONE WA S FOUND. 4 PATENTED CLAIMS.
Comment (Geology): MINERALIZATION IS LOCALIZED ALONG SEVERAL UNDULATIN G SHEAR ZONES IN HYDROTHERMALLY ALTERED ALASKITE, APLITE, & M ONZONITE.
Comment (Workings): SEVERAL SHAFTS, TRENCHES, AND TWO ADITS. THE LOWEST ADIT, WHICH IS CAVED AT THE PORTAL, IS AT EVELATION 4100 & I S 300 FT LONG. THE UPPER MAIN ADIT IS ABOUT 2000 FT SE OF THE LOWER ADIT AT ELEVATION 4580. THIS ADIT TRENDS N28W FOR 285 FT AND HAS A 40 FT CROSSCUT NEAR ITS FACE. ABOUT 140 FT FROM THE PORTAL, INTO THE ADIT, AN 80 FT RAISE EXTENDS TO THE SURF ACE, BUT IS INACCESSIBLE DUE TO CAVED GROUND. THE UPPER SHAFT S ARE REPORTED TO BE 50-60 FT DEEP.
Comment (Location): ON NE RIDGE OF BIMETHALLIC MTN.
Comment (Commodity): SEVERAL TONS CU-AU ORE 1918. 500 LB HIGH-GRADE MO ORE . SLIGHT RADIOACTIVITY IN ORE ZONES.
Comment (Development): ADITS, SHAFTS, TRENCHES; PRODUCTION IN 1918; DRILLH OLES, 1961.
Comment (Deposit): ORE IN FRACTURES & FAULTS; OXIDIZED COPPER MINERALI ZATION IN AN OVAL FRACTURE ZONE.
