VANCOUVER, BC / ACCESS Newswire / July 30, 2026 / Temas Resources Corp . ("Temas" or the "Company") (ASX:TIO)(CSE:TMAS)(OTCQB:TMASF)(FSE:26P0) and SAGA Metals Corp. ("SAGA") are pleased to announce the successful completion of an independent Stage 1 metallurgical validation program evaluating Temas' proprietary Regenerative Chloride Leach ("RCL") Platform Technology on representative titanium-vanadium-iron mineralization supplied by SAGA Metals. 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% . 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.

Summary of Stage 1 RCL Validation Results (SAGA Metals Corp.) As noted in SAGA's press release dated June 18, 2026 , the Hawkeye Davis tube analytical interpretation indicated that the non-magnetic fraction (i.e. ilmenite) commonly contains approximately 86-92% of the head TiO2. Stage-Gate Development Successfully Advances to Phase Two Following completion of the validation program, the independent technical review concluded that all Stage 1 objectives had been successfully achieved. As a result, the project received a positive Gate 1 recommendation to immediately advance into the Detailed Bench Optimization Program ("Stage 2"), where process conditions will be further optimized to maximize recoveries, reduce reagent consumption and generate engineering data required for future pilot-scale development.

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. For Temas, the successful completion of Stage 1 further validates the Company's strategy of developing the RCL Platform as a scalable critical minerals processing technology that can be deployed across multiple projects through licensing, joint ventures and strategic commercial partnerships.

Each successful third-party validation expands the potential addressable market for the technology while strengthening Temas' position as a developer of innovative, environmentally responsible metallurgical solutions. For SAGA Metals, the positive validation results provide an important technical foundation for evaluating alternative processing pathways for its titanium-vanadium mineralization. As global demand continues to accelerate for secure North American supplies of titanium, vanadium and other critical minerals, innovative extraction technologies capable of improving recoveries while reducing environmental impacts may offer significant advantages during future project development.

Building a Commercial Technology Platform Temas believes the mining industry is entering a period of significant transformation, driven by growing demand for critical minerals, increasing environmental performance expectations and the need for secure domestic supply chains in North America and allied jurisdictions. Processing technologies capable of improving recoveries, reducing waste streams and lowering environmental impacts are expected to become increasingly valuable as mining companies seek to maximize the economic potential of complex ore bodies. The RCL Platform has been developed to address many of these challenges through a proprietary regenerative mixed chloride process designed to improve metal extraction while reducing reagent consumption through continuous regeneration of the leach solution.

By validating the technology on third-party mineralization, Temas is demonstrating that the RCL Platform has the potential to become a commercially deployable processing solution for a broad range of critical mineral projects, complementing the Company's own mineral development portfolio and supporting the creation of a diversified technology licensing business. Next Steps Following the successful completion of the Stage 1 Validation Program, Temas and SAGA intend to advance to the Detailed Bench Optimization Program ("Stage 2"), which will focus on optimizing process conditions to further improve titanium recoveries, maximize reagent efficiency and generate the engineering data required for future scale-up. The Stage 2 program is expected to include optimization of leach chemistry, reagent regeneration, solid-liquid separation, impurity management and downstream metal recovery while continuing to evaluate the commercial applicability of the RCL Platform for SAGA's titanium-vanadium mineralization at the Radar Project (Cartwright, Newfoundland and Labrador).

Upon completion of Stage 2, the parties anticipate evaluating the potential advancement of the process through mini-pilot and pilot-scale demonstration programs. These programs are expected to provide additional engineering data to support future commercial design and economic assessment of the RCL Platform on SAGA's Radar Project. The successful completion of the Stage 1 validation program further strengthens Temas' strategy of establishing the RCL Platform as a commercially deployable metallurgical technology capable of supporting mining companies seeking efficient and environmentally responsible extraction of critical minerals.

Unlocking Value Through Technology Temas believes that the future of the mining industry will increasingly depend upon innovative process technologies capable of unlocking greater value from complex ore bodies while reducing operating costs and environmental impacts. As governments throughout North America, Europe and allied nations continue to prioritize secure domestic supplies of titanium, vanadium and other critical minerals, demand is expected to increase for advanced metallurgical technologies capable of improving recoveries and reducing dependence on conventional processing methods. Unlike traditional mineral development companies whose value is primarily derived from individual mining assets, Temas is executing a strategy that combines ownership of high-quality critical mineral projects with the commercialization of proprietary process technology.

The Company believes that successful deployment of the RCL Platform across multiple third-party projects has the potential to generate recurring revenues through technology licensing, engineering services, strategic partnerships and future commercial processing agreements. The successful validation of the RCL Platform on SAGA's mineralization represents another important milestone in that strategy by demonstrating that the technology can be successfully applied beyond Temas' wholly owned assets. As additional validation programs are completed on a broader range of critical mineral deposits, Temas expects to further expand the commercial opportunities available for the RCL Platform while strengthening its position as an emerging provider of innovative processing technologies for the global critical minerals industry.

Technical Summary The Stage 1 Validation Program evaluated three representative feed materials supplied by SAGA, including Run-of-Mine Massive Oxide material, Vanadium-Titanium Magnetite concentrate and ilmenite concentrate. The testing program successfully demonstrated increasing titanium recoveries as feed quality improved while maintaining consistently high recoveries of vanadium and iron throughout the evaluation. The ilmenite concentrate achieved the highest titanium extraction at 90.8%, while vanadium recoveries reached 97.4% and iron recoveries reached 91.5% under the test conditions evaluated.

The independent technical review concluded that all Stage 1 objectives had been successfully achieved and recommended advancement into the Detailed Bench Optimization Program.

ABOUT TEMAS RESOURCES Revolutionizing Metal Production Proprietary IP. Global Licensing. Titanium & Critical Minerals.

Temas Resources Corp. (ASX:TIO)(CSE:TMAS)(OTCQB:TMASF)(FRA:26P0) is a technology-driven critical minerals company advancing a dual-business model built around proprietary processing innovation and strategic mineral ownership. The Company's patented Regenerative Chloride Leach (RCL) technology platform delivers significant operational cost reductions - validated at up to 65% lower than traditional processing - while dramatically reducing energy use and environmental impact. Temas' RCL process is the foundation of its technology licensing and partnership business, enabling global mining and materials companies to adopt sustainable, high-margin metal extraction methods across a range of critical minerals including titanium, vanadium, nickel, and rare earth elements.

Complementing its technology division, Temas also owns 100% of two advanced titanium-vanadium-iron projects in Québec, Canada - La Blache and Lac Brûlé - which are strategically positioned to feed directly into the Company's proprietary processing platform, creating a fully integrated mine-to-market supply chain for Western metals. Through this combination of innovative IP commercialization and resource ownership, Temas Resources is positioned to deliver scalable, low-carbon solutions that strengthen Western critical-mineral independence and create long-term value for shareholders. Benefits the ORF - RCL Technology: The RCL platform technology involves the hydrometallurgical mineral extraction of concentrates, whole ores, slags and tailings to enhance recovery of critical metals, battery metals, Platinum Group Minerals ("PGMs"), precious and base metals and Rare Earth Element ("REE") recovery at materially higher through-yields and lower capital and operating costs than many of the conventional approaches that are in use traditionally.

This novel RCL technology is ideally suited to treat increasingly complex ores in an environmentally sensitive manner. Pilot Testing Complete: The Company has completed a pilot test of approximately 1 ton of material from its La Blache TiO 2 mineral property yielding 88 kgs of a 99.8% pure TiO 2 commercial grade product.[1] Validated Cost Reduction: A significant cost reduction of over 65%[2][3] is validated for TiO 2 processing using the RCL platform technology (e.g., reagent recycling, potentially lower energy use, optimized recovery etc.). These fundamental process efficiencies are expected to translate into economic advantages when applying the platform to Nickel or other target minerals hosted in complex ores.

Environmental Performance: The closed-loop design and high reagent recycling rates are core to the RCL platform, irrespective of the target mineral. Over 69% lower operating costs compared to conventional processing due to its core features operating at near ambient temperatures.[3] This means the reduced environmental footprint and enhanced ESG profile are benefits that extend to ores and minerals previously noted, not just TiO 2 . High Recovery Potential: Just as we've demonstrated high-quality, 99.8% TiO 2 product from pilot testing1 the RCL platform is engineered for high recovery and purity of all target metals.

Our metallurgical expertise focuses on optimizing these recoveries and maximizing margins for each specific mineral. 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.
