en.Wedoany.com Reported - Aclara Resources Inc. (TSX:ARA), a company listed on the Toronto Stock Exchange in Canada, announced on June 29, 2026, that its pilot plant in Santiago, Chile, has successfully developed "Super Pure Rare Earth Carbonate" (SPREC). This product contains approximately 99% rare earth elements, a significant improvement over traditional Mixed Rare Earth Carbonate (MREC), which has rare earth concentrations as low as 40%. This innovation will be applied to the company's Carina project in Brazil and the Penco module in Chile.

Aclara Resources Inc. is a company focused on establishing a vertically integrated supply chain for rare earth alloys used in permanent magnets. The company's two ionic clay deposits—the Carina project in Goiás, Brazil, and the Penco module in the Biobío Region, Chile—produce mixed rare earth carbonates with high concentrations of heavy rare earth elements. The development of Super Pure Rare Earth Carbonate is an innovative achievement that integrates the company's solvent extraction (SX) technical expertise from its downstream separation platform in the United States upstream into its "Circular Mineral Harvesting" (CMH) process.

Compared to traditional MREC, SPREC offers strategic and technical advantages across multiple dimensions. It boasts a rare earth content of approximately 99%, whereas traditional MREC can have rare earth concentrations as low as 40%; it eliminates impurities that affect the downstream separation of individual rare earth oxides; it enhances the blending flexibility of products from the Carina project and Penco module, allowing products from both locations to be efficiently separated through the same solvent extraction circuit; it significantly increases heavy rare earth concentration; it reduces logistics costs by transporting lower volumes of higher-value products; and it enhances value creation by integrating advanced solvent extraction technology within Brazil and Chile. By improving the quality of intermediate products at the source, the company aims to increase the efficiency, flexibility, and competitiveness of its downstream processing operations. Aclara will continue pilot-scale validation and process optimization in Santiago, and SPREC is expected to become the standard intermediate rare earth product after the commercial operation of both projects.

Aclara CEO Ramón Barúa stated that SPREC is a value-added product applying solvent extraction technology to operations in Brazil and Chile, with the goal of reducing operational risks at the separation plant. The new process can significantly reduce impurities—the primary source of complexity in solvent extraction plants. As the company plans to separate mixed rare earths from Brazil and Chile, the highest-purity carbonate reduces variability in the separation stage. This innovation not only simplifies downstream separation but also enables Brazil and Chile to capture greater value from their mineral resources. Aclara is building a competitive advantage through an integrated "mine-to-alloy" full-chain design.
