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): MINE DEVELOPED BY SEVERAL TUNNELS AND ABOUT 3000 FT OF DRIFT

Comment (Deposit): VANADIUM DEPOSIT IN ENTRADA SANDSTONE LIES NEAR CENTER OF SMALL MINERALIZED BELT WITHIN NE-CONCAVE CURVE OF LARGER PRINCIPAL MINERALIZED BELT. REPLACEMENT SULFIDE IN PONY EXPRESS LIMESTONE MEMBER OF WANAKAH FM LIES ABOVE VANADIUM LAYER AND IS RELATED TO NW-TRENDING GRAY HEAD FAULT, DOWWNTHROWN ON NE.

Comment (Location): MINE LOCATED ON HILLSIDE 0.45 MILE NE OF SAWPIT AND JUST NORTH OF BELLE CHAMPION MINE. ; INFO FROM LAND.ST :1975

Comment (Production): PARTIAL PRODUCTION RECORD. FIGURES FOR BASE AND PRECIOUS METALS UNKNOWN BUT CONSIDERED SMALL. NO ANNUAL FIGURES AVAILABLE FOR YEARS OTHER THAN 1951 AND 1954. NO REPORTED PRODUCTION AFTER 1954. CUMULATIVE TOTALS FROM NELSON-MOORE AND OTHERS.

Comment (Development): PRECIOUS AND BASE METALS PROBABLY WERE DISCOVERED IN LATE 1800S AND WORKED (IF AT ALL) FROM ABOUT 1890 TO 1910. V DEVELOPMENT AT MINE BETWEEN 1910 AND 1920 IS UNCERTAIN, BUT MINE DID PRODUCE SOME ORE AS LATE AS 1951 AND 1954. SOME DEVELOPMENT FOR AU AND AG DONE IN 1954, WITH FURTHER WORK AND ASSESSMENT IN 1958 AND 1961-1963.
