Brazilian Rare Earths (ASX:BRE) has declared Monte Alto “world-class” after making a number of discoveries there. Assay results from exploration at the Bahia, Brazil rare earths project returned outstanding grades and extended Monte Alto’s strike length by around 350 metres, to at least 1.2 kilometres.

CEO and MD, Bernardo da Veiga, said drilling has significantly expanded known high-grade mineralisation. “Monte Alto has quickly become the most significant rare earth discovery worldwide – pairing large-scale potential with exceptional rare earth grades and valuable critical mineral co-enrichment,” he said.
“The latest results validate continuity across thick high-grade horizons through systematic drilling. Importantly, our step-out programs are now defining new high-grade growth corridors and expanding the high-grade footprint.”
Drilling returned multiple high-grade hits, including up to 10,498 parts per million (ppm niobium oxide (Nb2O5), 303 ppm scandium oxide (Sc2O3), 612 ppm tantalum oxide (Ta2O5), and 4,047 ppm uranium oxide (U3O8).
The results confirmed a major strike extension supported by multiple near-surface total rare earth oxide (TREO) intercepts, including 9.9 m at 2.5% TREO.
Drilling also discovered an ultra-high-grade eastern parallel corridor.
The new Monte Alto corridor can be traced approximately 130m south and has linked step-out mineralisation with previously reported intercepts of 4.5 m at 5.0% TREO, including 0.8 m at 16.0% TREO.
“These results materially increase our confidence in both the scale of the ultra-high-grade mineralised envelope and the potential for further extensions well beyond the current footprint,” Mr da Veiga explained.
With plans to ramp up exploration, a diamond drill rig has been mobilised to the northern extension to accelerate drilling of the priority underlying hard-rock system.
BRE is up +3.18% to $4.06 through Wednesday.
