Mining district

District name Chisana

Comments on the production information

  • PLACER MINE ON LITTLE ELDORADO CREEK WAS MAJOR PRODUCER FOR CHISANA DISTRICT IN THE YEARS 1929 THROUGH 1932; TOTAL PRODUCTION FOR THE CHISANA DISTRICT HAS BEEN IN THE 40 TO 50 THOUSAND OZ RANGE

Comments on the workings information

  • SOME OF THE GRAVEL MINED WAS FROZEN; STREAM GRAVELS WERE REPORTED TO BE "WORKED OUT" BY 1914, WHEN ATTENTION TURNED TO BENCHES AND OLD CHANNELS

Comments on development

  • MINING METHODS: SIMPLE HYDRAULIC AND HAND METHODS ONLY; MAJOR YEARS OF PRODUCTION WERE BETWEEN 1913 AND 1940; SOME SMALL SCALE MINING TO PRESENT TIME, BUT PRODUCTION SINCE 1940 HAS BEEN INSIGNIFICANT
