Comments

Comment (Deposit): ORE WAS THICKEST AND EXTENDED DEEPEST NEAR SMALL NORTHEASTER FAULTS. ANOTHER MAJOR ORE BODY IN THE MINE WAS A LENS ROUGHLY 6 X 60 X 140 FEET. THE TWO MAJOR AXES WERE IN THE PLANE OF THE BEDS AND THE LONGEST AXIS WAS PARALLEL TO THE DIP

Comment (Location): N CENTRAL SEC. 26. ; INFO FROM LAND.ST :(1979)

Comment (Production): RECORDS INDICATE TOTAL ORE PRODUCTION OF 24,100 TONS AVERAGING 4.2 PERCENT COPPER AND 0.5 OZ. SILVER PER TON. PRODUCTION CEASED 1923

Comment (Development): OPERATORS INCLUDED MONONG AND DEVELOPMENT CORP OF DRAGOON MTN

Comment (Geology): GEOL.DESC: NORTHEASTER FAULTS REGARDED AS MINERALIZING FISSURES, BUT VALUABLE DEPOSITS FORMED NEAR COPPER CHIEF FAULT WHICH MAY HAVE ACTED AS A DAM FOR RISING SOLUTIONS.

Comment (Commodity): MOST VALUABLE DEPOSITS FORMED NEAR THE COPPER CHIEF FAULT
