South32, the world's biggest producer of manganese, is facing operational headwinds at its Illawarra Metallurgical Coal project after the miner undertook an extended planned longwall move at the Dendrobium mine.
Production volumes at the project will be weighted to the second half of fiscal 2024 owing to planned longwall moves across the year, the company added.
The Perth-based miner said production of metallurgical coal, used to make steel, fell to 1.0 million metric tons in the three months to Sept. 30, from 1.3 million metric tons a year earlier.
That was slightly lower than a consensus estimate of 1.1 million metric tons compiled by Visible Alpha.
