CAPACITY UNKNOWN:TOTAL OUTPUT CAPACITY OF POMFRET &KOEGAS (SEQ.NO.7910200039) IS 55,000 MTPY.MINING MAGAZINE SAYS ORE CAPACITY IS 1,000,000 TO 5,000,000 TPY RANGE. E/MJ SAYS IN 100,000 TO 500,000 TPY RANGE. ACCORDING TO DREYER&ROBINSON THE POMFRET FIELD HAS A MUCH GREATER GEOLOGICAL RESOURCE THAN THE KURUMAN OR POSTMASBURG FIELDS.DEPOSITS GENERALLY LARGER AND GRADES HIGHER BUT "HIDDEN"DEPOSITS(DUE TO THICK SAND-COVER&POOR OUTCROPS) WILL BECOME INCREASINGLY MORE DIFFICULT TO DISCOVER.EXPECTED YIELD FROM THIS FIELD IS 100,000 MTPY FIBER AND COULD GO BEYOND THE YEAR 2000.
