Brazilian Rare Earths’ Exceptional Yttrium-Rich Heavy Rare Earth Drill Results Expand Monte Alto District
Rhea-AI Summary
Brazilian Rare Earths (ASX: BRE, OTCQX: BRELY) reported new drilling from the Monte Alto HREE+Y Discovery, ~2.5 km south of the flagship Monte Alto Deposit in Bahia, Brazil. Six diamond holes totalling 604 m confirm high-grade heavy rare earth and uranium mineralisation continuing from the weathered profile into fresh bedrock.
Key intercept MADD0210 returned 2.5 m at 7.5% TREO from 6.0 m, including 1.3 m at 10.9% TREO with 5.8% Y2O3, 4,135 ppm Dy2O3, 488 ppm Tb4O7 and 1,588 ppm U3O8. Auger hole STU2478, ~200 m southwest, intersected 12 m at 8.7% TREO from 18 m to end of hole, remaining open at depth.
According to Brazilian Rare Earths, yttrium represents about 48–53% of TREO in all significant bedrock intervals, with a peak 58,249 ppm Y2O3. Four of the first six diamond holes carry significant heavy rare earth mineralisation. The company has formally consolidated the Monte Alto Deposit, HREE+Y Discovery, Velhinhas Corridor and regional corridors into a unified Monte Alto District, with follow-up diamond and auger drilling and a +5,000 m second-phase program at Velhinhas underway.

Drilling returns 1.3 m at
SYDNEY, July 15, 2026 (GLOBE NEWSWIRE) -- Brazilian Rare Earths Limited (ASX: BRE) (OTCQX: BRELY / BRETF) reports results from six diamond drill holes totalling 604 m at the Monte Alto HREE+Y Discovery, approximately 2.5 km south of the flagship Monte Alto Deposit in Bahia, Brazil.
The drilling confirms that the high-grade heavy rare earths – including yttrium, dysprosium, terbium – and uranium mineralisation previously identified at surface continues through the weathered profile and into fresh bedrock. Together with new shallow auger results and regional geophysics, the results further support a coherent district-scale exploration framework extending south from Monte Alto through the Velhinhas Corridor.
KEY HIGHLIGHTS
- Exceptional heavy rare earth grades: MADD0210 returned 2.5 m at
7.5% TREO from 6.0 m, including 1.3 m at10.9% TREO from 7.2 m, with 58,249 ppm (5.8% ) Y2O3, 4,135 ppm Dy2O3, 488 ppm Tb4O7 and 1,588 ppm U3O8 - New high-grade, heavy rare earth target remains open: Auger hole STU2478, located ~200 m southwest of the initial diamond drilling, returned 12 m at
8.7% TREO from 18 m to end of hole, including 1,004 ppm DyTb and0.44% Y2O3. The interval remains open at depth - Yttrium is a defining component, not a minor co-product: Yttrium represents over
50% of TREO in the peak interval - equivalent to approximately 58 kg of Y2O3 per tonne of sampled mineralised rock. Across every significant bedrock interval reported, yttrium represents approximately 48-53% of TREO - Exceptional grades confirmed in bedrock: Four of the first six diamond holes returned significant heavy rare earth mineralisation, materially strengthening the 2024 surface discovery that returned
14.6% TREO, including7.45% Y2O3 and 6,428 ppm DyTb1 - Monte Alto District formally adopted: BRE will now report the flagship Monte Alto Deposit, the Monte Alto HREE+Y Discovery, the Velhinhas Corridor and associated regional exploration corridors within one unified Monte Alto District exploration and development framework
- Large, active target pipeline: High-resolution geophysics has mapped multiple prospective corridors and numerous untested radiometric/magnetic exploration targets. Follow-up diamond and auger drilling is underway, including the +5,000 m second-phase program at Velhinhas

CEO COMMENTARY
“The defining feature of these results is not simply the
“The peak interval contains
“These results also complete the case for a unified Monte Alto District. The flagship Monte Alto Deposit provides exceptional grade and an advanced development anchor; the HREE+Y Discovery adds a highly differentiated concentration of yttrium, dysprosium and terbium; and Velhinhas adds multiple, large-scale, high-grade exploration corridors and regional growth potential. We will bring these mineralised centres together under the Monte Alto District name, while retaining their individual deposit, discovery and corridor identities.”
