Aclara Resources announces updated MRE for Carina Project

Aclara Resources (ARAAF) announced an updated mineral resource estimate for the Carina Project, the Company’s flagship ion adsorption clay project located in Goias, Brazil. The MRE represents a key component of the Carina pre-feasibility study and reflects considerable geological and technical advancements compared to the previously reported inferred mineral resource statement. Highlights: Updated MRE from “inferred” to “indicated” mineral resource category: By applying the principles of Reasonable Prospects for Economic Extraction and constraining the estimate within an optimized pit shell, the mineral resources have been refined and upgraded, resulting in 236 million tonnes of indicated mineral resources and 48 Mt of inferred mineral resources, compared with the 297 Mt of inferred mineral resources as reported in the 2024 Resource Statement. Consistent grades of magnetic rare earths: Indicated mineral resources report stable and consistent magnetic element grades, including dysprosium oxide at 42.7 ppm, terbium oxide at 6.8 ppm, and NdPr oxide at 292.6 ppm, closely aligned with the 2024 Resource Statement. Significantly improved geological confidence: The MRE is supported by 24,564 meters of drilling across 1,682 drillholes, representing approximately a 500% increase in drilling compared to the 2024 Resource Statement, which was based on 4,104 m of drilling across 363 drillholes. Strong geo-metallurgical database supports robust process: The MRE is supported by 14,001 samples analysed for total rare earth oxides, desorbable rare earth oxides, and impurities, providing a granular understanding of the Project’s geo-metallurgical behaviour compared to 2024 Resource Statement, which was based on 3,789 samples. High conversion rate of mineral resources demonstrates consistent mineralization: Approximately 79% of inferred mineral resources have been successfully upgraded to the indicated mineral resource category. Declaration of reserves expected with PFS: The indicated mineral resources serve as the foundation for the PFS mine plan and the subsequent estimation of mineral reserves.
