| Deposit | ALTHOUGH BARLOW RAND HAS NO DIRECT CHROMITE MINING INTEREST, IT OBTAINS PROFITS FROM THIS INDUSTRY THROUGH ITS 100% INTEREST IN RAND MINES, WHICH OWNS 100% OF NETHERBURN. NETHERBURN HAS BEEN A MAJOR PRODUCING OPERATION SINCE 1981. THIS ANALYSIS TREATS A SINGLE SECTION OF THE GREAT DYKE-" THE NETHERBURN SECTION"- AS ONE MINING UNIT. IN REALITY, MORE THAN ONE COMPANY CAN HOLD LEASES OVER THE SECTION DESCRIBED AND THER MAY BE SIMULTANEOUS PRODUCTION FROM DIFF- ERENT COMPANIES IN THE SECTION. TO ANALIZE THE GREAT DYKE FOR AVAILABILITY IT WAS NECESSARY TO ADDRESS THE SITUATION IN A LOGIICAL, COMPARTMENTALIZED FORMAT. HENCE,"THE NETHERBURN SECTION" REFERS TO A 21KM LONG SECTION COVERING THE WEST LIMB OF THE GREAT DYKE STRUCTURE FROM OPPOSITE THE TOWN OF LALAPANZI TO A POINT WHERE THE QUE QUE TO UMUKMA ROAD PASSES OVER THE DYKE. |
