  5. Slide 5: Exploration-led Growth Strategy

    Exploration-led Growth Strategy The 10,000m drilling programme at Piracanjuba North, the current drill focus within the Azimuth project, is complete and attention has shifted to Plateau resource definition, with multiple near-term catalysts within scope. In parallel, high-grade projects in the U.S.

  6. Slide 6: AZIMUTH — Securing an Optimal IAC Setting

    AZIMUTH — Securing an Optimal IAC Setting Azimuth holds a district-scale position in Goiás, Brazil, where deep tropical weathering over a granitic protolith provides the setting for ion-adsorption clay (IAC) REE discovery. Piracanjuba North is the current drilling focus within that package. ✓ Distri

  7. Slide 7: PIRACANJUBA NORTH — Advantage of IAC from Granite

    PIRACANJUBA NORTH — ADVANTAGE OF IAC FROM GRANITE Piracanjuba North, the current drilling focus within Magnum’s 1,049km² Azimuth package, hosts IAC in a granite plateau with the potential for a simple, low-cost and high-value rare earths operation. TESTING FOR: LOW COST · SIMPLE PROCESS · HIGH-VALUE

  8. Slide 8: Why Desorbable Grade Is the Number That Matters

    Why Desorbable Grade Is the Number That Matters With 373 drillholes now reported, the key question is no longer simply how much REE is present — it is how much is released from the saprolite under mild leach conditions, and whether that response repeats across the plateau. Head grade Desorbable grad

  9. Slide 9: What Comes Off the Clay, and Where It Sits

    What Comes Off the Clay, and Where It Sits Across the current published saprolite dataset, mild leaching increases the magnet-REE share of the released basket, while the strongest continuous D-TREO sections occur within selected shallow saprolite intervals. Highest 4 m D-TREO composites using comple
