Comments on the production information

  • PRODUCTION OF URANIUM HAS NOT BEEN RESUMED TO DATE ; PRODUCTION FIGURES INCLUDED IN VAAL REEFS RECORDS AS WELL AS AFRIKANDER LEASES DUE TO THE FACT THAT VAAL IS MINING AFRIKANDER LEASE MINE. AFRIKANDER LEASE IS HOWEVER A PRIMARY URANIUM PRODUCER. ; PRODUCTION FIGURES ARE INCLUDED IN VAAL REEFS RECORDS AS WELL AS AFRIKANDER LEASES DUE TO THE FACT THAT VAAL REEFS IS MINING AFRIKANDER LEASE. HOWEVER, SINCE AFRIKANDER IS REGARDED AS A PRIMARY URANIUM PRODUCING MINE, PRODUCTION APPEARS IN THIS RECORD AS WELL.

Workings at the site

  • Type of workings Underground
    Overall depth 500M

Comments on the workings information

  • MAIN DEVELOPMENT ALONG LOWER REEF, AS REEF DRIVES, WHICH WILL PROVIDE A FOOTWALL TO UPPER REEF. MOST DEVELOPMENT WILL BE INTO REEF ONLY. A SMALL AMOUNT OF OFF-REEF TONNAGE WILL BE HOISTED OR STORED UNDERGROUND.

Comments on development

  • MINE WAS ORIGINALLY A GOLD MINE, BUT IS BEING EXPLOITED PRIMARILY AS A URANIUM PRODUCER (AS FROM 1980), WITH GOLD NOW ONLY A SECONDARY PRODUCT. ; DEV$: 23 ; EXPAN$: 95 ; ECON.COM: MINE IS A LOW GRADE MARGINAL MINE WHERE THE GOLD DISTRIBUTION WITHIN THE ORE BODY IS EXTREMELY ERRATIC.

Deposit INFORMATION MERGED FROM RECORD NUMBER W032369 ; W032950 ; W033082 ; W044625 ; W055258
Deposit ORE BODY CONSISTS OF 2 URANIUM-BEARING CONGLOMERATES-THE UPPER AND LOWER REEFS AT BASE OF THE DOMINION REEF SERIES & RESTING ON BASEMENT GRANITE. REEFS CROP OUT IN NORTH MINING AREA, DIP SOUTH & WEST & ARE SEPARATED BY QUARTZITE BED. REEFS HEAVILY DISRUPTED BY FAULTS. UPPER REEF (MAIN URANIUM-BEARING REEF) PERSISTS THROUGHOUT MINING AREA & CONTAINS HI-GRADE ORE SHOOTS. HIGH URANIUM VALUES MORE LIMITED IN LOWER REEF.
Deposit First Production Year: 1888 (GOLD); 1980 (URANIUM)
