Brazilian Rare Earths (ASX: BRE) has confirmed exceptional heavy rare earth grades at its Monte Alto district in Bahia, Brazil. The numbers point to yttrium as a defining feature of the deposit, not a minor credit.

The standout hole sits at the Monte Alto HREE+Y Discovery, 2.5 kilometres south of the flagship Deposit. It returned 1.3 metres at 10.9% total rare earth oxide, including 58,249 ppm yttrium oxide. Surface mineralisation found back in 2024 has now turned up in fresh bedrock too.
Key Highlights
- MADD0210 assayed 2.5m at 7.5% TREO from 6.0m, including 1.3m at 10.9% TREO from 7.2 m
- At the highest profile, this interval returned 58,249 ppm Y2O3, 4,135 ppm Dy2O3 and 488 ppm Tb4O7 alongside a U3O8 grade of 1,588 ppm
- Auger hole STU2478 returned 12 m at 8.7% TREO from 18 m to end of hole, remaining open at depth
- Yttrium represents approximately 48 to 53% of TREO across every significant bedrock interval reported
- BRE has formally adopted the Monte Alto District name, unifying the Deposit, the HREE+Y Discovery and the Velhinhas Corridor
- A Scoping Study and Mineral Resource estimate for the wider Rocha da Rocha province is expected in August 2026
CEO Commentary
Managing Director and CEO Bernardo da Veiga said the composition of the rare earths matters more than the headline grade. He noted that “the defining feature of these results is not simply the total rare earth grade” but the heavy rare earth composition behind it.

Da Veiga explained that the peak interval contains roughly 58 kilograms of yttrium oxide per tonne of sampled rock, along with strong dysprosium and terbium credits. He added that the Monte Alto Deposit, the HREE+Y Discovery, and the Velhinhas Corridor now form a single combined growth pathway for the Company.
Exceptional Heavy Rare Earth Grades Confirmed In Bedrock
Brazilian Rare Earths Limited completed six diamond drill holes totalling 604 metres at the Monte Alto HREE+Y Discovery between November 2025 and January 2026. Four of the six holes returned significant heavy rare earth mineralisation in fresh bedrock.

The Company said the drilling confirms that yttrium, dysprosium, terbium and uranium mineralisation seen at surface continues below the weathered profile. This is a central pillar of the wider Monte Alto Yttrium Discovery Australia narrative building around the Project.

Auger Results Extend The Target
- STU2478 returned 12 m at 8.7% TREO from 18 m to end of hole, including 1,004 ppm DyTb and 0.44% Y2O3
- STU2499 returned 2.7 m at 3.2% TREO from 5 m to end of hole, approximately 150 m north of STU2478
- Both intercepts remain open at depth and define a 200 m target trend for further diamond drilling

Why The Yttrium Grade Matters
Yttrium behaves differently to most rare earths tracked on the ASX. It performs under extreme heat, corrosive plasma and high-frequency conditions rather than magnet strength alone.
The element supports jet turbine coatings, semiconductor plasma resistance, laser crystals and radar components. BRE cited United States Geological Survey data showing the United States remains a fully net importer, with almost all supply refined in China.

Heavy Rare Earth And Yttrium Discovery At Monte Alto
The HREE+Y Discovery sits on the eastern margin of the Volta do Rio Plutonic Suite. R458 is a grab sample first identified by Prospecting, returning 14.6% TREO in outcropping mineralisation.

The diamond drilling has, by now, intersected a hydrothermal breccia vein, rich in biotite and hosting dozy jumps of yttrium, dysprosium and terbium over a downdip distance of about 75 metres. A second, deeper horizon was also intersected in the two holes (MADD0207 and MADD0209), noting that this zone is connected to a high-grade auger anomaly approximately 100 metres from where the outcrop was discovered.
Formal Adoption Of The Monte Alto District
BRE will now report four components under one Monte Alto District framework. This follows the district concept introduced in the Company’s June 2026 Velhinhas announcement.
- The flagship Monte Alto Deposit
- The Monte Alto HREE+Y Discovery, approximately 2.5 km south
- The Velhinhas Corridor, extending mineralisation more than 10 km south
- The Monte Alto East, West and associated regional target corridors
The unified structure links exploration activity to BRE’s planned Camaçari rare earth processing hub in Bahia, according to the ASX Announcement.

District Growth Program And Next Steps
BRE plans step-out diamond drilling to test continuity along strike and down-dip from the HREE+Y Discovery. The Company will also continue its second phase diamond program at Velhinhas, targeting more than 5,000 metres across four parallel trends.
Close-spaced auger drilling will test the strongest radiometric anomalies across the East, Monte Alto and West corridors. Assays remain pending for a further 18 auger holes totalling 301 metres.

Brazilian Rare Earths Limited (ASX: BRE) shares reflect renewed investor attention on the Monte Alto Yttrium Discovery Australia story following this ASX Announcement. Share price movements should be independently verified before making any investment decision.
Industry Outlook
Global demand for heavy rare earths continues to climb as defence, semiconductor and clean energy manufacturers seek supply outside China. Yttrium in particular faces constrained substitution options across electronics, lasers and phosphors.
This supply gap underpins renewed interest in a Yttrium Discovery Australia Mining pipeline such as Monte Alto. Industry watchers on the ASX mining sector expect processing hubs like Camaçari to shorten the path from discovery to offtake.
Future Direction And Impact On Monte Alto District Growth
The near-term focus at Monte Alto is resource definition. A Scoping Study and Mineral Resource estimate covering the Rocha da Rocha province and Camaçari hub is expected during August 2026.
Step-out and infill diamond drilling will continue through 2026 and 2027 to test geological and grade continuity around the HREE+Y Discovery. Results from this work will decide whether the mineralisation holds up over mineable widths.
At Velhinhas, the second phase diamond program keeps advancing across four parallel mineralised trends, with more than 5,000 metres planned. Auger drilling is also underway across the East, Monte Alto and West corridors, with assays still pending for 18 holes totalling 301 metres.
Longer term, BRE plans geotechnical, hydrological and metallurgical studies to support a future Pre-Feasibility Study for Monte Alto. The Company is also pursuing additional land acquisition across the wider Rocha da Rocha province.
BRE has linked this growth to its planned Camaçari rare earth processing hub, which it describes as the largest petrochemical and industrial centre in the southern hemisphere. Investor attention is likely to stay on newsflow from pending assays and the August Scoping Study.
