tonnes and Cannington payable zinc equivalent production by 6% to 195,900 tonnes.
Wet weather and temporary disruptions at the Appin metallurgical coal mine led to a 21% drop in metallurgical coal production in the March quarter from a year earlier and a 7% cut in output guidance for the year. South32 said it now expects to produce 6.5 million tonnes of Illawarra metallurgical coal for the year to June 2023, down from a forecast of 7.0 million tonnes. However, the company said it remains on-track to meet its full year production guidance at most of its operations.
"We remain well positioned to capitalise on improved market conditions, with higher production volumes expected to finish the 2023 financial year," CEO Graham Kerr said in a statement. The company raised its operating unit cost guidance for metallurgical coal to $127 per tonne from $119 for the year, due to the production disruptions.
