Manganese ore – Consistently strong operating performance and improved plant availability at GEMCO (Australia) contributed to record ore production in the September 2012 quarter.

Manganese alloy – The resumption of production at TEMCO (Australia) in July 2012 led to a substantial increase in alloy production from the June 2012 quarter. The decline in alloy production from the September 2011 quarter reflected the permanent closure of energy intensive silicomanganese production at Metalloys (South Africa) in January 2012.
