Ultra-High-Grade Drilling Materially Expands Monte Alto
Rhea-AI Summary
Brazilian Rare Earths (ASX: BRE, OTCQX: BRELY/BRETF) reported diamond drilling results from the ultra-high-grade Monte Alto rare earths deposit in Bahia, Brazil, based on 10,000 m of new drilling. The program tested southern and eastern/down-dip extensions, infill between existing holes, and deeper historical holes.
Key intersections include 25.6 m at 17.4% TREO from 174 m, including 8 m at 28.1% TREO (MADD0230), and 9.4 m at 21.8% TREO from 161.7 m, including 6.2 m at 25.4% TREO (MADD0093). Additional step-out and infill holes returned multiple intervals above 16% TREO. The company highlighted strong enrichment of NdPr up to 6.7% and heavy rare earths plus high-grade niobium, scandium, tantalum and uranium co-products. All results are post the current Mineral Resource and Scoping Study cut-off date of 22 February 2026 and are not yet included in those estimates. Monte Alto remains open to the north, south and east, with Brazilian Rare Earths advancing a +5,000 m growth drilling campaign and planning an updated Mineral Resource estimate by end-2026.
Positive
- 25.6 m at 17.4% TREO, including 8 m at 28.1% TREO (MADD0230)
- 9.4 m at 21.8% TREO, including 6.2 m at 25.4% TREO (MADD0093)
- Multiple step-out holes above 19% TREO expand mineralised envelope
- Infill intercepts up to 32.0% TREO improve internal continuity
- NdPr grades up to 66,640 ppm (6.7%) plus heavy rare earths
- High-grade co-products including up to 1.1% Nb₂O₅ and 4,443 ppm U₃O₈
- All new results post-cut-off, potential upside to future resource estimate
- +5,000 m growth drilling and northern corridor program already underway
Negative
- New drilling results not yet included in current Mineral Resource estimate
- Deposit remains open in three directions, requiring further drilling spend
- Updated Mineral Resource only targeted by end of 2026, delaying re-rating
News Explained
Access now enables a 1,400 m northern program, while Velhinhas has completed 1,250 m across broader exploration trends.
The results disclosure confirms that recent site access now enables a near-term 1,400 m drill program in Monte Alto’s northern corridor; that work is planned, not reported as completed.
At Velhinhas, a separate 5,000 m district program is underway, with 1,250 m completed across targets spanning more than 9 km of cumulative exploration trends.

10,000 m of new drilling delivers major ultra-high-grade extensions to the south and east/down dip and establishes a priority growth corridor to the north
SYDNEY, Aug. 26, 2026 (GLOBE NEWSWIRE) -- Brazilian Rare Earths Limited (ASX: BRE) (OTCQX: BRELY / BRETF) announces results from a diamond drilling campaign at the ultra-high-grade Monte Alto Rare Earths Deposit in Bahia, Brazil. The campaign has tested the extensions of the deposit, infill drilled between existing holes and extended selected historical holes deeper.

ULTRA-HIGH-GRADE EXTENSIONS AT MONTE ALTO DEPOSIT
- Major southern high-grade extension: 25.6 m at
17.4% TREO from 174 m, including 8 m at28.1% TREO from 189 m (MADD0230), extends the down-dip mineralised envelope to the south - Ultra-high-grade eastern/down-dip extension: 9.4 m at
21.8% TREO from 161.7 m, including 6.2 m at25.4% TREO from 162.8 m (MADD0093), confirms the eastern growth front remains open down dip - Repeated step-out success: 6.6 m at
21.2% TREO (MADD0219), 6.8 m at19.1% TREO including 2.2 m at28.2% TREO (MADD0216) and 5.2 m at17.0% TREO including 2.7 m at26.0% TREO (MADD0216) - Strong, high-grade infill results: 12.3 m at
16.5% TREO, including 4.9 m at32.0% TREO (MADD0246); 16.7 m at12.6% TREO (MADD0213); and 21.1 m at9.4% TREO, including 3.5 m at25.6% TREO (MADD0233) - North emerges as a growth corridor: Initial high-grade results in the far-north cluster confirm REE-Nb-Sc-Ta-U mineralisation and recent drill site access now unlocks full target corridor for near-term 1,400 m drill program
- Exceptional rare earth enrichment: NdPr grades up to 66,640 ppm (
6.7% ) plus heavy rare earth grades Dy2O3 up to 2,853 ppm and Tb4O7 up to 471 ppm, Y2O3 up to 27,077 ppm and Gd2O3 up to 3,348 ppm - High-grade co-products: Assays up to 10,986 ppm (
1.1% ) niobium oxide (Nb₂O₅), 318 ppm scandium oxide (Sc₂O₃), 610 ppm tantalum oxide (Ta₂O₅), and 4,443 ppm uranium oxide (U₃O₈)
GROWTH PATHWAY BEYOND THE CURRENT MINERAL RESOURCE
- Entirely post-MRE cut-off: The current Monte Alto Mineral Resource and Scoping Study Production Target were based on drilling available only up to 22 February 2026; none of the results reported here were included
- Open in three directions: The new drilling has expanded Monte Alto's mineralised envelope and remains open to the north, south and east, with new down-dip potential. Northern strike-extension confirmed
- Growth drilling underway: BRE is advancing the planned +5,000 m drilling campaign across the northern, southern and eastern growth fronts to continue expanding the mineralised envelope
- Next value steps: validated post-cut-off drilling is targeted to be incorporated into an updated Mineral Resource Estimate by the end of 2026
- Monte Alto District: +5,000 m diamond drilling program underway at Velhinhas, 5 km south of the Monte Alto Deposit, with 1,250 m completed to date testing priority targets across >9 km of cumulative exploration trends
"Monte Alto continues to deliver the two outcomes that matter most for future resource growth: exceptional high-grade mineralisation beyond the margins of the existing model and stronger geological continuity within the deposit.
Drillhole MADD0230 is a standout result - 25.6 metres at
The strategic significance is clear. The current Monte Alto production case is based only on drilling available to 22 February 2026. Since then, our team has successfully expanded the interpreted mineralised envelope volume to the south and east/down dip, while continuing to deliver ultra-high grades and advancing the open northern corridor. The additional scale immediately strengthens the Project’s value proposition and, subject to conversion into Mineral Resources, could create substantial value through mine-life extension or increased annual production."
