Core Insights - Brazilian Rare Earths Limited (BRE) has reported significant exploration results at the Sulista Project, confirming the discovery of an ultra-high-grade REE-Nb-Sc-Ta-U deposit and a new mineralised corridor [1][5] Group 1: Exploration Results - The Sulista West diamond drilling results revealed ultra-high-grade mineralization, with notable drillhole JITDD0006 showing 20.4m at 11.8% Total Rare Earth Oxides (TREO) and 4.2m at 18.9% TREO [2] - Additional highlights include drillhole JITDD0011 with 12.0m at 12.5% TREO and 4.2m at 17.0% TREO, and JITDD0004 with 5.5m at 10.7% TREO and 1.0m at 17.0% TREO [2] - The highest uranium and tantalum grades recorded since exploration began in 2021 include up to 8,211 ppm U3O8 and 2,803 ppm Ta2O5 [4] Group 2: New Discoveries - A new "Outcrop Ridge" discovery was made with grab samples showing up to 20.6% TREO, located 2.5 km southwest of the Sulista West deposit, indicating significant extension potential [4] - Ultra-high-grade boulder samples at Sulista North revealed assay grades of 21% TREO, including 37,390 ppm NdPr and 6,588 ppm Nb2O5 [4] Group 3: Strategic Implications - The exploration results bolster confidence in the Rocha da Rocha Province's potential to host multiple Monte Alto-style ultra-high-grade rare earth deposits, which could have major implications for the strategic supply of heavy rare earths and other critical minerals [5]
