Temas Resources Corp and Saga Metals Corp Successfully Validate Rcl Technology with Titanium Recoveries of Up to 90.8% and Vanadium Recoveries of 97.4%

Temas Resources Corp. and SAGA Metals Corp. have successfully completed an independent Stage 1 metallurgical validation program utilizing Temas' proprietary Regenerative Chloride Leach (RCL) Platform Technology on representative samples from SAGA's titanium-vanadium-iron mineralization. The results exceeded program objectives, achieving titanium recoveries of up to 90.8%, iron recoveries of up to 91.5%, and vanadium recoveries of up to 97.4% during two-stage RCL testing, demonstrating excellent extraction of critical minerals from multiple feed types. By meeting all Stage 1 objectives, the validation program supports a positive Gate 1 decision to advance into the Detailed Bench Optimization Program (Stage 2), representing an important next step toward pilot-scale demonstration and potential commercial deployment. The program validates the application of the RCL Platform on third-party titanium-vanadium-iron mineralization, providing further evidence of the commercial scalability of Temas' proprietary processing technology. The ilmenite concentrate produced the strongest titanium extraction, achieving 90.8% recovery, while iron extraction remained consistently above 86% across all samples and vanadium extraction exceeded 94% in every test. Results demonstrate the versatility of the RCL Platform across multiple titanium-bearing feedstocks, supporting future commercial opportunities through technology licensing, strategic processing partnerships and joint venture arrangements. Stage 2 optimization will focus on further improving recoveries while advancing process design toward mini-pilot scale demonstration. The successful validation represents another important milestone in Temas' strategy of building a global critical minerals technology business capable of providing environmentally responsible processing solutions for mining companies worldwide. The validation program evaluated three representative feed materials, including a Run-of-Mine (ROM) Massive Oxide sample, a vanadiferous titanomagnetite (VTM) concentrate and an ilmenite concentrate, using the Temas RCL mixed chloride leaching process under standardized operating conditions. The program was designed to assess the extraction behaviour of titanium, vanadium and iron while determining the suitability of the RCL Platform for future commercial development on SAGA's mineralization. The results exceeded the objectives established for the Stage 1 validation program, producing titanium recoveries of up to 90.8%, iron recoveries of up to 91.5%, and vanadium recoveries of up to 97.4%. The independent technical assessment concluded that the program successfully satisfied all Stage 1 criteria and recommended advancement to the Detailed Bench Optimization Program (Stage 2), representing an important milestone toward pilot-scale testing and commercial implementation. The successful validation represents considerably more than a positive metallurgical test program. It demonstrates the broader commercial applicability of the Company's proprietary RCL Platform beyond its wholly owned La Blache and Lac Brûlé projects and supports Temas' long-term strategy of commercializing the technology through licensing agreements, strategic partnerships and deployment across third-party critical mineral projects globally. As demand continues to grow for secure Western supplies of titanium, vanadium and other critical minerals, innovative processing technologies capable of improving recoveries while reducing environmental impact are expected to become increasingly valuable throughout the global mining industry. The successful completion of the Stage 1 validation program represents another important step in the commercialization of Temas' proprietary Regenerative Chloride Leach (RCL) Platform Technology. Unlike conventional metallurgical test work conducted solely on company-owned assets, this program was designed to evaluate the applicability of the RCL process on third-party titanium-vanadium mineralization under a structured stage-gate development framework. The program assessed three representative feed materials supplied by SAGA, including Run-of-Mine (ROM) Massive Oxide material, a vanadiferous titanomagnetite (VTM) concentrate and an ilmenite concentrate. The objective was to validate the performance of the RCL Platform across varying mineralogical compositions while generating the technical data necessary to support future optimization and commercial process design. Across all three feed materials, the RCL Platform consistently demonstrated strong extraction performance for titanium, vanadium and iron while maintaining stable operating conditions throughout the test program. Titanium extraction increased significantly with feed upgrading, culminating in recovery of up to 90.8% from the ilmenite concentrate. Vanadium recoveries remained exceptionally high across all samples, ranging from approximately 94% to 97.4%, while iron recoveries exceeded 86% in every test, reaching a maximum of 91.5%. These results provide important validation that the RCL Platform is capable of efficiently processing multiple titanium-bearing feedstocks while producing high recoveries of critical minerals that are essential to aerospace, defence, renewable energy, infrastructure and advanced manufacturing industries. Feed Material Titanium Recovery Vanadium Recovery Iron Recovery ROM Massive Oxide 78.1% 97.4% 91.5% VTM Concentrate 30.3% 97.4% 91.4% Ilmenite Concentrate 90.8% 97.4% 86.7%. Stage 2 optimization is expected to focus on refining operating parameters including leach chemistry, residence time, reagent recycling, impurity management and downstream metal recovery. The resulting data will support future engineering studies and process scale-up while further demonstrating the commercial viability of the RCL Platform across a broader range of titanium-vanadium deposits. This means the reduced environmental footprint and enhanced ESG profile are benefits that extend to ores and minerals previously noted, not just TiO2. Just as we've demonstrated high-quality, 99.8% TiO2 product from pilot testing the RCL platform is engineered for high recovery and purity of all target metals. RCL results in a quicker and more complete liberation of the target metals using atmospheric pressure and lower temperatures than competing methods and improves the selectivity and efficiency of subsequent solvent extraction steps. Management believes that this novel metallurgical process can be applied to many complex resource deposits worldwide, enhancing both extraction and recovery for the operator.
