Rio Tinto on Wednesday reported its lowest first-quarter iron ore shipments since 2019 and warned that more weather disruptions could lead to a 2025 forecast miss, after cyclones impacted the miner's Pilbara operations.

Iron-ore shipments from Rio Tinto’s massive Australian mining operations are likely to fall at the lower end of the miner’s estimates this year, following disruptions from four cyclones in recent months.

Extreme weather in Western Australia and Brazil during the first quarter has caused Rio Tinto’s iron ore production to fall to the lowest level in six years. The mining giant celebrated a record first quarter for bauxite production.
