Brazilian Critical Minerals (BCM) Investor presentation summary

Investment highlights

• Ema Project hosts 943Mt @ 716ppm TREO, with a 341Mt starter zone containing 26% high-value magnet REEs, ranking among the largest ionic clay REE projects globally.

• Innovative in-situ recovery (ISR) method validated by field trials, enabling low-cost, low-impact extraction outside China.

• Scoping study projects post-tax NPV of US$498M, IRR of 55%, and a 2-year payback, with capex of just US$55M including 35% contingency.

• Board and management team have extensive rare earths and mine development experience.

• Recent equity raise of $3.5M to advance the Ema Project to BFS and offtake.

Resource base and project scale

• Central Starter Area contains 341Mt @ 746ppm TREO, with 73% classified as Indicated Resource.

• Global Mineral Resource Estimate totals 943Mt @ 716ppm TREO, inclusive of the starter zone.

• High-value magnet REEs (Nd, Pr, Dy, Tb) make up 25-26% of TREO in both starter and global resources.

Mining method and environmental impact

• ISR mining is cost-effective and environmentally friendly, requiring no land clearing, open pit mining, or large processing facilities.

• Utilizes green reagents with no detrimental environmental effects and achieves high recoveries through ionic leaching.

• ISR leverages natural permeability and gravity, with proven technology and minimal surface disturbance.
