Brazilian Rare Earths Achieves Exceptional Ore Sorting Results at Monte Alto

Rhea-AI Summary

Brazilian Rare Earths (ASX: BRE / OTCQX: BRELY) reported exceptional sensor-based ore sorting at Monte Alto, achieving >2x grade upgrades from 12.4% TREO to ~27% TREO in single-pass and producing a +20% TREO product with cumulative recoveries of ~96–99%.

Tests rejected ~25% of feed mass as waste with 0.3% rare earth loss, delivered +95% yields, and support a dry, lower-cost beneficiation flowsheet targeting processing of 100% run-of-mine material.

SYDNEY, Feb. 04, 2026 (GLOBE NEWSWIRE) -- Brazilian Rare Earths Limited (ASX: BRE / OTCQX: BRELY) (‘BRE’) is pleased to report exceptional results from sensor-based ore sorting test work program that confirms its suitability for Monte Alto’s beneficiation process flowsheet. 

Key Highlights

• Exceptional grade enrichment (+100%): Achieved grade upgrade factors of >2x, increasing feed grades from 12.4% TREO to ~27% TREO, using multi-sensor ore sorting
• High-grade product in single-pass: Produced a +27% TREO ultra-high grade product with single-pass processing
• World-class recoveries (95%): Cascade ore sorting produced a +20% TREO rare earth product, with exceptional cumulative recoveries of ~96–99% and upgrade factors of 1.3x-1.7x
• Efficient waste rejection: Successfully rejected ~25% of feed mass as waste with negligible rare earth loss (<0.3% of contained metal)
• Simple, dry beneficiation: Results validate ore sorting for Monte Alto mineralisation – delivering a high-grade product at yields of +95%, highlighting the potential for downstream direct rare earth extraction
• Lower costs: Lower capex and operating costs, with enhanced economics

BRE Managing Director and CEO, Bernardo da Veiga, commented:

“These exceptional ore sorting results from run-of-mine Monte Alto feedstock have exceeded all our expectations. They demonstrate that sensor-based concentration can significantly enhance project economics with +95% yields at lower capital and operating costs, whilst simultaneously reducing environmental footprint through lower energy, minimal water and no reagents.

Our metallurgical programs are designed to maximise the value of Monte Alto’s ultra-high grade rare earth, uranium, scandium, niobium, and tantalum mineralisation. These ore sorting results build on our previous metallurgical programs with the Australian Nuclear Science and Technology Organisation (ANSTO) and provide a pathway for world-leading mineral-to-product yields.

Last year’s metallurgical program with ANSTO successfully demonstrated direct hydrometallurgical processing of high-grade Monte Alto mineralisation, including impurity removal, uranium recovery and the production of high-purity mixed rare earth carbonate.

Importantly, the multi-sensor ore sorter enriched run-of-mine Monte Alto feedstock by over two times in a single pass, producing a concentrate of +27% TREO. Subsequent cumulative ore sorter runs produced a +20% TREO concentrate at very high total recoveries of 96-99%.

Rare earth projects are typically characterised by low head grades and complex, high-cost processing flowsheets. Monte Alto’s ultra-high grades can deliver a beneficiated product at grades that are suitable for direct hydrometallurgical processing. BRE will now progress flowsheet design, targeting a multi-sensor system capable of processing 100% of Monte Alto’s run-of-mine material at +95% yields.”

FAQ

What ore sorting results did Brazilian Rare Earths (BRELY) announce on February 4, 2026?

The company reported >2x grade upgrades and a +27% TREO concentrate in single-pass sorting. According to the company, subsequent runs produced a +20% TREO product with cumulative recoveries of ~96–99% and very low contained metal losses.

How did the Monte Alto ore sorting affect recoveries and waste rejection for BRELY?

Ore sorting achieved cumulative recoveries of about 96–99% while rejecting ~25% of feed mass as waste. According to the company, rejected material contained <0.3% of contained rare earth metal, preserving most recoverable value.

What processing yields and flowsheet implications did BRELY report for Monte Alto ore sorting?

BRELY reported +95% yields from dry sensor-based beneficiation and validated direct hydrometallurgical processing. According to the company, this supports a simpler, lower-cost flowsheet with minimal water, no reagents, and reduced energy use.

Will Brazilian Rare Earths (BRELY) scale ore sorting to treat all Monte Alto run-of-mine material?

The company plans to target a multi-sensor system capable of processing 100% of run-of-mine material at +95% yields. According to the company, flowsheet design will progress to enable this full-processing objective.

What economic benefits did BRELY highlight from the Monte Alto ore sorting results for investors?

BRELY cited lower capital and operating costs alongside higher product grades and yields. According to the company, sensor-based concentration can enhance project economics by reducing processing complexity, energy, water use, and downstream treatment requirements.
