ALL QUARRIES EXTEND OVER A N-S STRIKE LENGTH OF 2.6 KM (ORE BODY DIPS AT 65 DEGREES TO THE EAST (SERPENTINITE ORE BODY CAN BE TRACED FOR A TOTAL OF 3.8 KM SOUTHWARDS TO THE NORTH BANK OF THE KOMATI RIVER (DOES NOT OUTCROP ON THE SOUTH BANK BUT DRILLING BY FEDERALE MYNBOU BEPERK HAS REVEALED ITS PRESENCE A FEW HUNDRED FEET SOUTH OF THE RIVER. THICKNESS OF ORE BODY VARIES FROM 49 TO 213 M. MINERALIZATION AS STOCKWORK OF CROSS-FIBRE CHRYSOTILE SEAMS FROM .8MM TO 19 MM IN WIDTH. FIBER CONTENT VARIES CONSIDERABLY BUT AS A WHOLE RANGES FROM 4-22%. ALSO KNOWN AS THE MSAULI ASBESTOS MINE. IT IS COMPOSED OF 2,122 CLAIMS ON DIEPGEZET 388JU AND NOOITGEZIEN31U FARMS ABOUT 24 KM SSE OF BARBERTON. ALL WEATHER, GRAVEL SURFACE ROAD (35 MILES) FROM BARBERTON TO MINE.

CHRIS & ANNA PLANT CAPACITIES-680 MT ORE FEED/DAY. SEVENS PLANT LOCATED AT ANNA QUARRY RIM TO EXTRACT SOME OF THE ULTRA-SHORT 6 AND 7 GRADE FIBERS. ANNA & CHRIS PLANTS PRODUCE GRADE 4&5 FIBER. NEW MILL CONSTRUCTED 1967-1969 BECAUSE OLD MILLS OBSOLETE AND IT WAS UNECONOMICAL TO CONVERT THEM TO MEET NEW HEALTH REGULATIONS. 72 MILL DESIGN CAPACITY IS 38,100 MTPY OF GRADES 4,5,6&7 FIBER.PERCENTAGE OF OUTPUT OF VARIOUS GRADES UNKOWN.
