Gove: Crusher and export uptime plus truck utilisation at 63.5% kept Gove materially ahead of forecast despite maintenance swaps.

Weipa: Northern and Southern operations closed above forecast with strong plant performance; truck EU remains a watchpoint due to labour availability.

Yarwun: Wirth pump availability constrained Yarwun by 1.3 kt versus plan; remediation crews engaged for the digester swap outage.

QAL (100%): QAL held marginally above weekly forecast thanks to average flow, though yield remains below plan pending oxalate drum maintenance.

BSL (73.5%): BSL closed marginally above forecast with current efficiency favourable at 94.2% and amperage on target.

NZAS: NZAS lifted above plan as CIC improved to 607.1 versus 606.4 forecast, supported by reduced metal levels.

Tomago (51.55%): Tomago inventory recovery lifted output 2.1 kt above plan; attention remains on closing pot room reliability gaps.

Risk spotlight

Operational upsides or downsides executives should track closely.

downsideAlumina

Multiple outages in SPL settling, seawater supply, and coarse seed capability continue to cap QAL throughput despite mitigation work.

downsideAluminium

Protracted metal flow delays and low baked anode stocks threaten aluminium stability if potline catch-up slips.

downsideAluminium

High cell failure rates exiting September keep the smelter below desired cells-in-circuit, requiring accelerated rebuild plans.
