Total bauxite production (crude output plus alumina equivalent) reached ~1.47 million tonnes in Q3 2025, down 6.7% from Q2 but 8.8% higher year-on-year. The quarterly decline reflected weaker output across major producers following strong early-year performance.

Discovery Bauxite posted a 4.9% reduction in bauxite output to 448,933 tonnes, though volumes remained 22.2% higher than Q3 2024, supported by its ongoing ramp-up toward a 4 million DMT target for the year. Jamalco fell 6.5% to 784,889 tonnes, despite maintaining a 12.0% YoY increase, while Windalco recorded the steepest quarterly decline, down 10.3% to 231,609 tonnes, 16.8% lower than its outturn in Q3 2024. Alpart’s operations remain suspended.

Despite the Q3 slowdown, YTD output rose 4.4% to ~4.69 million tonnes, driven by Jamalco’s strong YoY gains and Discovery’s robust performance earlier in the year.
