The world’s No. 1 miner by market value produced more iron ore and copper over the past year, but flagged possible delays and cost increases at the giant potash project it is building in Canada’s Saskatchewan province.

BHP Group on Friday reported better-than-expected iron ore output for the fourth quarter and hit the upper end of guidance for both iron ore and copper output in fiscal 2025, helped by supply-chain strength at its central Pilbara hub.

BHP Group, the world’s largest miner, said output of key revenue-earner iron ore rose 2% in its latest quarter compared with the year before.
