Comments

Comment (Geology): ORE DEPOSITION PROBABLY CONTROLLED BY A COMBINATION OF STRUCTURE (FAULTS & FRACTURES) AND STRATIGRAPHY-PERMEABLE SAND STONE, LIMESTONE, IN CONTACT WITH LESS PERMEABLE SHALE BEDS. TWO STAGE OF MINERALIZATION; AN EARLY BARITE STAGE CARRYING LITTLE OR NO SILVER, AND A LATER QUARTZ STAGE, ACCOMPANIED BY ORE SULPHIDES.

Comment (Location): ON NW SLOPE OF SHOSHONERANGE

Comment (Production): PRODUCTION LISTED IS FOR ENTIRE LEWIS DISTRICT, BUT NEARLY ALL PRODUCTION WAS FROM BETTY O'NEAL MINE SPECIFICALLY: 4,204,657 OZ. AG; 298,280 LB. CU; 1,670,502 LB. PB. PEAK PRODUCTION YEARS WERE FROM 1922 TO 1928 WHEN IT WAS ONE OF THE BIGGEST SILVER PRODUCERS IN THE STATE.

Comment (Deposit): ORE DEPOSITION POCCURRED IN TWO STAGES: AN EARLY BARITE STAGE CARRYING LITTLE OR NO SILVER AND A LATER QUARTE STAGE, ACCOMPANIED BY ORE SULFIDES.

Comment (Workings): AT LEAST ONE SHAFT AND THE GETCHELL TUNNEL

Comment (Deposit): DISCOVERED IN 1880, MINING OF HIGH-GRADE ORE PROGRESSED TO 1882, WHEN A COMBINATION OF BAD EXPLOSION, BAD GROUND, AND WATER CONDITIONS FORCED CLOSURE. EFFORTS BEGAN IN 1910 TO UNWATER THE SHAFT, AND PRODUCTION WAS ERRATIC AND MOSTLY UNRECORDED UNTIL 1920. N.H. GETCHELL IN 1920 FORMED A STOCK COMPANY AND GEGAN THE GETCHELL TUNNEL AND 100-TON FLOTATION MILLS. MINING CONTINUED TO 1967 MORE EXPLORATION WAS DONE TO DETERMINE FEASIBILITY OF REOPENING THE MINE.
