Alumina - Record annual production at the Alumar refinery (Brazil) contributed to a four per cent increase in total alumina production in the 2012 financial year. Production at Worsley (Australia) is expected to increase during the 2013 financial year as the Efficiency & Growth project ramps up towards full capacity.
Aluminium - Production was lower than all comparable periods as potline capacity at Hillside (South Africa) remained curtailed following a major unplanned outage in the March 2012 quarter. Operations are expected to progressively return to full technical capacity during the 2013 financial year.
Despite our competitive position on the cost curve, our integrated Aluminium business continues to be challenged by weaker prices and underlying cost pressure.
