Deposit CAMBRAI IS A MAJOR PRODUCER AS OF 1981. THIS ANALYSIS TREATS A SINGLE SECTION OF THE GREAT DYKE- "THE CANBRAI SECTION" - AS ONE MINING UNIT, IN REALITY, MORE THAN ONE COMPANY MAY HOLD LEASES OVER THE SECTION DESCRIBED AND MORE THAN ONE COMPANY CAN BE PRODUCING AT THE SAME TIME GROM THE SECTION. TO ANALYZE THE GREAT DYKE FOR AVAILABILITY IT WAS NECESSARY TO ADDRESS THE SITUATION IN A LOGICAL, COMPARTMENTALIZED FORMAT. HENCE THE "CAMBRAI SECTION" REFERS TO A 14 KM SEC- TION COVERING THE EAST LIMB OF THE GREAT DYKE STRUCTURE FROM THE TOWN OF LALAPANZE TO THE BOMZEZAAN RIVER. IT IS INTENDED TO COVER 3 PRODUCING SECTION- THE CAMBRAI, LALAPANZE AND
