Deposit IT IS THOUGHT THAT SOME PRODUCTION CAME FROM THIS SECTION IN 1980.THIS ANALYSIS TREATS ONE SECTION OF THE GREAT DYKE STRUCTURE-THE WINDSOR/YORK/YORK WEST SECTION-AS ONE MINING UNIT.IN REALITY MORE THAN ONE COMPANY MAY OWN LEASES OVER THE SECTION AND SIMULTANEOUS PRODUCTION IS POSSIBLE.TO ANALYZE THE GREAT DYKE FOR AVAILABILITY IT WAS NECESSARY TO ADDRESS THE SITUATION IN A LOGICAL,COMPARTMENTALIZED FORMAT. HENCE,THE "WINDSOR/YORK/YORK WEST" SECTION REFERS TO A 20 KM SECTION COVERING BOTH LIMBS OF THE GREAT DYKE STRUCTURE, FROM THE UMNIATI RIVER SOUTHWARDS TO SOUTH LATITUDE 19 DEG. 0 MIN.
