BBX Minerals Limited (ASX: BBX) has announced that initial reconnaissance auger drilling for rare earth elements (REEs) conducted on its three new leases within the Apuí region in Brazil has reported significant Total Rare Oxide (TREO) values.
The obtained values demonstrate the persistence of REEs in the regolith with a clear enrichment in HREO with depth in holes APTR 001, 002, 004, and 010, with grades obtained compatible with typical ionic REE deposits, such as Makuutu in Uganda. All auger holes were terminated, due to intersection of the water table or hard ironstone, in REE mineralization with grades higher than 200ppm TREO-CeO2.
The auger holes were over 1km apart, strategically conducted to validate the presence of RREs within the regolith in the target areas with a specific radiometric signature. The total tested area of these radiometric targets was 92.39km2, 39% of the total area with the ternary radiometric signature. The specific ternary radiometric signature, distinct from that of the surrounding rocks, is similar to that observed at Makuutu, a surface signature characteristic of the zones enriched in REEs.
Significant results include:
• APTR 001: 12m @606ppm TREO from surface
• APTR 002: 12m @714ppm TREO from surface
• APTR 004: 9m @815ppm TREO from surface, including 4m @930ppm TREO from 5m
The company has stated that the auger results combined with soil sampling results, and the distinctive radiometric ternary signature demonstrate the potential to define a world class REE deposit within the large Apui project area.
To further investigate the REE distribution within the weathered zone to assist in identifying the highest-grade zones, the programme of broad-spaced auger drilling will continue. This drilling campaign aims to obtain a more detailed understanding of the REE profile and potential enrichment within the weathered zone, as well as the potential areal extent of high-grade mineralization to define zones for detailed drilling, including sonic drilling, for an MRE.
