Comments on the production information

  • PARTIAL PRODUCTION RECORD. FIGURES FOR BASE AND PRECIOUS METALS UNKNOWN BUT CONSIDERED SMALL. NO ANNUAL FIGURES AVAILABLE FOR YEARS OTHER THAN 1951 AND 1954. NO REPORTED PRODUCTION AFTER 1954. CUMULATIVE TOTALS FROM NELSON-MOORE AND OTHERS.

Comments on the workings information

  • MINE DEVELOPED BY SEVERAL TUNNELS AND ABOUT 3000 FT OF DRIFT

Comments on development

  • PRECIOUS AND BASE METALS PROBABLY WERE DISCOVERED IN LATE 1800S AND WORKED (IF AT ALL) FROM ABOUT 1890 TO 1910. V DEVELOPMENT AT MINE BETWEEN 1910 AND 1920 IS UNCERTAIN, BUT MINE DID PRODUCE SOME ORE AS LATE AS 1951 AND 1954. SOME DEVELOPMENT FOR AU AND AG DONE IN 1954, WITH FURTHER WORK AND ASSESSMENT IN 1958 AND 1961-1963.
