    First Ore Mined

    Open-pit mining commenced; concentrate shipped to Gebeng for processing.

    Completed2011
  4. ✓

    HREE Annulus Discovery

    Lynas confirmed a massive xenotime/churchite annulus zone surrounding the Crown Deposit, with Dy2O3 contained up 92%. First meaningful change to deposit geometry in decades.

    CompletedQ1 2026
  5. ◉

    HREE Commercial Separation at Gebeng

    Commercial-scale separation of heavy rare earths (Dy, Tb) added to Gebeng refinery alongside existing LREE stream.

    In ProgressH2 2026
  6. ○

    HREE Production Ramp-up

    Full ramp-up of HREE output as xenotime blend is steadily increased in the mine feed.

    Pending2027

Analyst Notes

March 2026 HREE upgrade: Lynas proved massive Xenotime/Churchite annulus zone — contained Dy₂O₃ up by 92%. Now targets Xenotime and Churchite (HREE-rich minerals) alongside traditional Monazite (LREE). Commercial HREE separation confirmed at Gebeng (Malaysia) for H2 FY2026.
