Brazilian Rare Earths Limited has intersected 25.6 metres at 17.4% Total Rare Earth Oxide from 174 metres, including an 8-metre interval grading 28.1% TREO, in a diamond drilling campaign at the Monte Alto Rare Earths Deposit in Bahia, Brazil.

The latest assay results extend the down-dip mineralised envelope to the south and confirm ongoing continuity across multiple growth fronts. Drillhole MADD0093 returned 9.4 metres at 21.8% TREO from 161.7 metres, including 6.2 metres at 25.4% TREO, demonstrating that the eastern growth front remains open down dip. Step-out drilling also yielded 6.6 metres at 21.2% TREO in hole MADD0219 and 6.8 metres at 19.1% TREO in hole MADD0216. Infill results included 12.3 metres at 16.5% TREO with 4.9 metres at 32.0% TREO in hole MADD0246.

“Drillhole MADD0230 is a standout result - 25.6 metres at 17.4% TREO, including 8 metres at 28.1% TREO - while the MADD0093 extension confirms that the same high-grade, multi-element system continues down dip. The compelling step-out drill results delivered repeatable high grades across several growth fronts, and the infill program has returned both ultra-high-grade assays and broad mineralised envelopes.”

The current drilling sits entirely outside the cut-off date of 22 February 2026 used for the existing Mineral Resource Estimate and Scoping Study Production Target. Brazilian Rare Earths previously completed more than 32,000 metres of diamond drilling at Monte Alto to establish its foundational geological model. The project is underpinned by a scoping study released in August 2026 featuring an after-tax net present value of approximately US$6 billion and an internal rate of return of approximately 90%.

The company is advancing a more than 5,000-metre drilling campaign across the northern, southern and eastern growth fronts at the deposit. Initial high-grade results in the far-north cluster have confirmed rare earth, niobium, scandium, tantalum and uranium mineralisation, while recent drill site access has unlocked the full target corridor for near-term work.

Validation and incorporation of the post-cut-off drilling into an updated Mineral Resource Estimate for Monte Alto is targeted by the end of 2026. Elsewhere in the surrounding district, Gold Mountain Limited reported drill results from the Irajuba Prospect at its Down Under project.
