Key developments during FY2019
In October 2018, BHP awarded Thiess a mining services contract to complete end-to-end mining services in the Ayredale and Roxburgh pits (referred to as Mt Arthur South) over five years. Thiess was identified as the preferred contractor, with expertise in existing operations at the southern area of the main pit and terrace mining techniques demonstrated at nearby operations. Under the new contract, Thiess is appointed statutory mine operator of Mt Arthur South, with scope including vegetation clearing, mine planning, drill and blast, overburden and coal mining.
BHP will remain mine and lease holder of Mt Arthur South and Mt Arthur North, and mine operator of Mt Arthur North.
NSWEC is transitioning to a strategy of optimising product quality. Volume is expected to decrease and unit costs to increase in the short term. We expect that benefits of the multiple elevated roadways project and continued improvements to truck and shovel productivity will lead to lower unit costs in the medium term.
