Brazilian Rare Earths’ Exceptional Yttrium-Rich Heavy Rare Earth Drill Results Expand Monte Alto District

· Issued by Brazilian Rare Earths Limited via GlobeNewswire

Drilling returns 1.3 m at 10.9% TREO, including 58,249 ppm Y2O3 and 4,623 ppm DyTb, confirming exceptional heavy rare earth assemblage in bedrock just ~2.5 km south of the flagship Monte Alto Deposit

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 at 10.9% 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 and 0.44% 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, including 7.45% 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
