IGO cuts Greenbushes FY2026 guidance as ore-grade decline accelerates

Talison Lithium/Greenbushes lithium mine

IGO downgraded full-year FY2026 production to 1.375–1.425 Mt from 1.5–1.65 Mt, citing structural ore-feed grade decline. The mine is working lower-grade zones, reducing lithium extraction per tonne and raising operational costs.
