Comments on the production information

  • PARTIAL PRODUCTION RECORD. ANNUAL TOTALS UNAVAILABLE FOR YEARS PRIOR TO 1920: CUMULATIVE ESTIMATE OF ORE THROUGH 1920 FROM FISCHER AND OTHERS. ANNUAL TOTALS FOR 1942 AND 1943 FROM CDM RECORDS. NO PRODUCTION IN 1940 OR APPARENTLY AFTER 1943. NELSON-MOORE AND OTHERS' LOW CUMULATIVE TOTAL COULD REPRESENT ONLY PRODUCTION OF ORE FOR URANIUM DURING 1940S AND 1950S.
