A second LiebherrR9800 is operating at the mine and beingserviced by a fleet of Caterpillar 797 dumptrucks. The result of this muscle is the costeffective removal of overburden, nearly30 per cent of which is being removedfor the second time as we go back intoareas of Burton first mined in 1996.10,000 HOURS OF TYRE LIFEThe Thiess Tyre Life Improvement Programis another example of the way our teamconstantly looks to improve performance.The program has achieved more than10,000 hours of tyre life on our Caterpillar793 haul trucks at Lake Vermont.
