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.
Slide 6: AZIMUTH — Securing an Optimal IAC Setting
AZIMUTH — Securing an Optimal IAC Setting Within that province, Azimuth holds a district-scale position where deep tropical weathering over granitic source rocks provides the setting for ion-adsorption clay (IAC) REE discovery. Piracanjuba North is the current drilling focus within that package. ✓ D
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. LOW COST · SIMPLE PROCESS · HIGH-VALUE BASKET WHY I
Slide 8: Why Desorbable Grade Is the Number That Matters
Why Desorbable Grade Is the Number That Matters In ionic adsorption clay deposits the rare earths sit loosely on clay particles rather than locked inside hard mineral crystals, so a portion is released by washing with a mild salt solution, avoiding the crushing, roasting and aggressive chemistry har
Slide 9: What Comes Off the Clay, and Where It Sits
What Comes Off the Clay, and Where It Sits At Piracanjuba North, desorption does more than release rare earth. The material recovered by the leach is richer in the high-value magnet rare earths than the rock it came from, and the mineralisation itself sits in a shallow band close to surface. [26] 9
Slide 10: PIRACANJUBA NORTH — Drilling, Workstreams and Infrastructure
PIRACANJUBA NORTH — Drilling, Workstreams and Infrastructure DRILLING PROGRAMME ▪ 10,000m auger programme complete: 10,313.97m across 867 collars (15 September 2026 data cut) [28] ▪ Plateau focus: approximately 7,137.42m across 576 collars, now the priority for infill and resource definition, with a
