| Deposit | GOLD OCCURS AS DISSEMINATED, LOW-GRADE ORE IN HAMBURG DOLOMITE, FORMING A NUMBER OF SHOOTS CONTROLLED BY INTERSECTION OF NE-STRIKING FISSURES OR FAULTS WITH THE UPPER HAMBURG DOLOMITE. MINERALIZATION HERE IS UNIQUE FROM REST OF DISTRICT IN THE PAUCITY OF LEAD AND SILVER. THE RUSTLER DEPOSIT, AN EXTENSION OF THE WINDFALL DEPOSIT 0.5 MILE SOUTH WAS FOUND AND PUT INTO PRODUCTION. MUCH OF THE RUSTLER ORE OCCURS IN ZONES THAT HAVE BEEN THOROUGHLY SILICIFIED AND SOME BRECCIATED. DRILLING HAS SHOWN THAT ORE GRADE MATERIAL EXTENDS FROM THE SOUTH END OF THE WINDFALL PIT TO THE NORTH END OF THE RUSTLER PIT. |
| Deposit | THE DEPOSIT WAS DISCOVERED IN 1904 AND FROM 1908 TO 1916 65,32 TONS VALUED AT $349,428 WERE PRODUCED. THE PROPERTY IS LOCATED AT THE SOUTHERN END OF THE DUNDERBERG-WINDFALL BELT. THE PROPERTY IS NOW OWNED BY THE IDAHO MINING COMPANY (1978) AND THEY WERE ACTIVITY OPEN PIT MINING AND HEAP LEACHING THE ORE. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; 3 FIELD OBSERV |
