Subject category Comment text
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.
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. NORANDA COMPANY
