The Brazilian Rare Earths Ltd (ASX: BRE) share price is in focus today after the company revealed a major step forward at its Monte Alto project, with drilling results showing ultra-high-grade rare earth extensions not included in its current mineral estimate and a new growth corridor emerging in the north.

What did Brazilian Rare Earths report?
- ~10,000 m of new diamond drilling at Monte Alto has expanded the high-grade mineralised envelope by around 50% compared to the February 2026 model.
- Southern extension: 25.6 m at 17.4% TREO, including 8 m at 28.1% TREO (MADD0230).
- Eastern/down-dip extension: 9.4 m at 21.8% TREO, including 6.2 m at 25.4% TREO (MADD0093).
- Strong infill and step-out results across several fronts, with multiple intercepts exceeding 20% TREO and individual assays up to 36.5% TREO.
- Major critical mineral credits: niobium oxide up to 1.1%, scandium, tantalum and uranium also present at elevated grades.
- None of these new results are yet included in Monte Alto's Mineral Resource Estimate or production case.
What else do investors need to know?
The new drilling campaign has established several high-grade growth fronts to the south, east/down-dip, and north of the existing Monte Alto deposit. The mineralised system remains open in all directions, and a follow-up program of over 5,000 m is already underway to test further extensions.
A standout development is the unlocking of a northern corridor, where the company now has land access for a 1,400 m drill program to bridge the gap between the main deposit and a new high-grade northern discovery. These results create a clear pathway for resource growth, with potential mine life extension or increased production following the next resource update.
What did Brazilian Rare Earths management say?
CEO & Managing Director Bernardo da Veiga said:
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 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 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.
What's next for Brazilian Rare Earths?
Brazilian Rare Earths' immediate focus is on completing over 5,000 m of additional drilling to further test and define high-priority growth vectors around Monte Alto. A new Mineral Resource Estimate is planned for the end of 2026, which will incorporate these results for the first time.
Alongside drilling, the company is progressing mine planning and scoping work, including an ongoing pre-feasibility study that could underpin either an extended mine life or boosted annual output. Regional drilling at nearby targets also continues, underlining a broader district-scale growth strategy.
