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 (Location): CONNECTED WITH MOORE SHAFT. ; INFO FROM LAND.ST :1979

Comment (Production): PRODUCED INTERMITTENTLY 1882-1949. PRODUCTION RECORD COMBINED WITH REPUBLIC MINE, BUT MAMMOTH PRODUCED MUCH LESS THAN REPUBLIC, ALTHOUGH MORE THAN THE INTERVENING COPPER CHIEF. ABGMT-USBM PRODUCTION FIGURES ARE INCLUDED UNDER REPUBLIC-MAMMOTH-MOORE

Comment (Development): PREVIOUS OPERATORS INCLUDE BLACK PRINCE COPPER CO, ARIZONA CONSOL IDATED MINING CO, ARIZONA UNITED MINING CO, COBRIZA MINES DEVELOPMENT CO, MASON COPPER CO, UNITED DEVELOPMENT CO, CORONADO, COPPER AND ZINC CO. THE REPUBLIC AND MAMMOTH HAVE HAD COMMON OWNERSHIP AT LEAST SINCE 1900, BY WHICH TIME THEY WERE DEVELOPED BY SURFACE CUTS AND SHALLOW IN CLINED SHAFTS DOWN THE DIP OF OUTCROPPING ORE BODIES. IN 1903 THE BLAC K PRINCE COPPER CO EXTENDED THE MAMMOTH SHAFT TO 270 FT

Comment (Deposit): LARGEST CHIMNEY 400 BY 45 BY 25 FT. TABULAR BODIES SMALLER THAN CHIMNEYS - MAX 10 FT THICK.

Comment (Workings): EXTENSIVE SHAFT WORKINGS; PARTLY CAVED INCLINES AND UNDERHAND STOPES FOLLOWING DOWN DIP OF FAVORABLE BEDS

Comment (Deposit): THIS REPORT REPRESENTS A MERGER OF ORIGINAL RECORD M050012 WITH RECORD M030574 OF JAN WILT IN MOLYBDENUM FILE, CONTACT PERSON IS T.G. THEODORE, USGS. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
