Comments on the geologic information

  • THE MUSOSHI ZONE IS SITUATED IN THE EXTENSION TOWARDS ZAMBIA AND LIES ALONG THE SE LIMB OF KAFWE ANTICLINE. 17 CONSTITUTES THE NORTH FLANK OF THE KONKOLO DOME. THE MINERALIZED BED OCCURS IN THE LOWER ROAN SERIES AND IS IN THE BOTTOM SILTSTONE FORMATION WHICH CORRESPONDS TO THE SHALE IN ZAMBIA. A DISTRIBUTION INTO THREE SUPERIMPOSED ZONE CAN BE NOTED IN THESE MINERALIZED SILTSTONES. FROM BOTTOM TO TOP THERE ARE A BORNITE ZONE, A CHALCOPYRITE ZONE, AND A PYRITE ZONE. FROM SURFACE DOWN TO A DEPTH OF 50 METERS THE COPPER MINERALS HAVE BEEN OXIDIZED OR LEACHED.

General comments

Subject category Comment text
Deposit COMPANY HAS LOST ABOUT $60,000,000 SINCE 1972.
Deposit SODIMIZA HAS BROUGHT KINSENDA MINE INTO PRODUCTION IN ORDER TO OFFSET THE LOWER-THAN-EXPECTED ORE GRADE AT MUSOSHI. PRODUCTION WILL BE CUT BACK IN PROPORTION TO THE AMOUNT OF HIGH GRADE ORE TRUCKED FROM KINSENDA.
