Diversified miner South32 has warned that production from its Illawarra metallurgical coal operations was likely to be 10% below previous guidance of 7.9-million tonnes, after operations at the Appin Area 7 and Area 9 longwalls were suspended.
The company said on Wednesday that elevated gas concentrations were recorded at Appin Area 7 earlier this week, resulting in staff being evacuated from the area.
