Most importantly, 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.

For Temas, 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.

Tim Fernback, President & Chief Executive Officer, commented:

"Today's announcement represents one of the most important commercial milestones achieved by Temas since acquiring the RCL Platform Technology. While we have consistently demonstrated the capabilities of the RCL process on our own mineral assets, successfully validating the technology on third-party mineralization is another significant step toward building a global critical minerals processing business.

Recoveries of up to 90.8% titanium and 97.4% vanadium show how well RCL adapts across different feedstocks and give us confidence it can offer miners a lower-cost, lower-impact route through complex critical mineral deposits. With Stage 1 complete and Stage 2 recommended, commercial deployment moves closer, and with it the licensing, processing partnerships and commercial agreements that build long-term shareholder value."

Mike Stier, Chief Executive Officer and Director of SAGA Metals Corp., commented:

"Completing the Stage 1 bench-scale scoping test with Temas' proprietary RCL technology marks an incredible milestone for SAGA and the future of the Radar Project. Achieving these recoveries, particularly the strong titanium, iron, and vanadium extractions at this early stage, without the benefit of detailed mineralogical analysis or process optimization, is significant.

These results provide a clear and encouraging path forward as we advance the stages of development, with the goal of further maximizing recoveries and unlocking the full potential of the Radar titanium-vanadium-iron project.

Unlike conventional processing routes that typically produce mid-stream saleable products, the RCL technology positions us to pursue the production of final downstream products for direct market access directly on site. With the Radar Project located less than 20 km from a deep-water port, this represents a compelling opportunity to develop a more integrated, value-added critical minerals operation in Labrador."

Commercial Validation of the RCL Platform

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.
