    Length 396.24M
    Overall depth 32.61M

Comments on the workings information

  • SHAFT, DRIFTS, STOPES. CURRENTLY THERE ARE 3 TRENCHES WHICH RUN E-W UP THE HILL. THEY ARE EACH ABOUT 200 FT LONG BY 15 FT WIDE BY 20 FT- DEEP. A DOZER CUT ROAD RUNS ACROSS UPPER AREA OF TRENCHES. LO-OKS LIKE NONE OF THE TRENCHES HIT BEDROCK, ALTHOUGH TRENCHES A-RE SOMEWHAT SLOUGHED IN. AN OPEN CUT LIES TO NORTH OF NORTHERN-MOST TRENCH-NO BEDROCK EXPOSED IN IT. BETWEEN THIS PROPERTY A -ND RED ORE #1 ARE NUMEROUS CUTS AND TRENCHES, MINOR ADITS. SUR-FACE WORK DONE PROBABLY IN LATE 1960'S - EARLY 1970'S. OPEN SH-AFT APPROXIMATELY 40 FT DEEP LOCATED BELOW TRENCHES AND TO THE- IMMEDIATE NORTH. A SHALLOW TRENCH LIES NORTH OF SHAFT.

Comments on development

  • 30 TON HERRESHOFF (1940), SMALL ROTARY FURNACE (1943)

Deposit ORE DEPOSITION OCCURS IN THE EASTERN DIABASE DIKE AND IN WALL ROCK
Deposit DISCOVERY WAS MADE BY DR. W.C. MCADOO IN 1936. THE LESSEE, FULTON QUICKSILVER CO., DID LITTLE WORK ON IT THROUGH 1938. IN 1939, BALDWIN & MCADOO INSTALLED 8 PIPES OF A RETORT AND RECOVERED 161 FLASKS HG. IN 1940, USING A 30-TON HERRESHOFF FURNACE, THEY RECOVERED 838 FLASKS, AND 629 FLASKS IN 1941. THE PROPERTY WAS CLOSED DOWN FROM 1942 TO 1943, WHEN A SMALL ROTARY FURNACE WAS USED TO TREAT ORE SORTED FROM DUMPS. NEW LESSEES IN 1943 BEGAN A DRILLING PROGRAM THE MINE IS DEVELOPED BY A 107-FT SHAFT, AND 1300 FT OF DRIFTS AND STOPES ON SEVERAL LEVELS THE PROPERTY WAS LEASED TO A. MINNEY IN 1952, WHO DID CONSIDERABLE NEW DEVELOPMENT WORK AND INSTALLED A 2-TUBE RETORT IN 1954 TO TREAT 25 LB/TON ORE. DEVELOPMENT CONSISTS OF A 107-FT. INCLINED SHAFT WITH ABOUT 1300 FT. OF UNDERGROUND WORKINGS ; INFO.SRC : 1 PUB LIT; 3 FIELD OBSERV
