Temas Advances Commercialisation of Patented 'RCL' Metallurgical Processing Technology

Executive Summary

• Temas Resources completed pilot‑scale testing of its Regenerative Chloride Leach (RCL) platform on ~830 kg of La Blache deposit material, producing 88 kg of 99.8 % pure TiO₂ and demonstrating >65 % cost reduction versus conventional TiO₂ processing.
• Two‑stage leach achieved 80–85 % titanium recovery and ~95 % iron recovery; solvent‑strip extraction removed 99.9 % of iron from solution.
• The company is expanding metallurgical work to recover vanadium, gallium and scandium, with additional results expected later this quarter and into Q1‑Q2 2026, while evaluating licensing and joint‑venture opportunities worldwide.

Key Details

• RCL Platform Ownership: 11 granted patents acquired via 100 % purchase of ORF Technologies Inc. (announced Oct 30 2025).
• Pilot Test Scope: Processed ~830 kg composite ore from La Blache titanium‑vanadium project.
• TiO₂ Production: 88 kg of ultra‑low impurity TiO₂ powder, 99.8 % purity (commercial grade).
• Recovery Rates:
• Titanium: 80–85 % overall recovery (two‑stage leach).
• Iron: ~95 % overall recovery; solvent strip removed 99.9 % of iron from solution.
• Cost Reduction: Demonstrated >65 % operating cost reduction versus conventional TiO₂ routes, driven by co‑product capture, closed‑loop reagent recycling, simplified flowsheets and lower energy intensity.
• Future Metallurgical Work:
• Pyrohydrolysis testing planned to produce premium Fe₂O₃ (>99 % purity) for pigment/battery markets.
• Ongoing evaluation of HQ core from 2025 drill program (4,915 m) plus 36,844 m historic core to optimise vanadium recovery and develop gallium & scandium extraction processes.
• Commercialisation Efforts: RCL under confidential discussions with mining/materials companies in Indonesia (Ni/Co/Mg/Fe), Australia (Au/Fe), British Columbia (Au/Ag/Zn/Pb) and Ontario (TiO₂/V/Mg/Fe) for licensing or joint‑venture opportunities.
• Strategic Positioning: RCL presented as a scalable, commodity‑agnostic platform enabling a technology‑led, capital‑light business model focused on licensing, partnerships and internal project enhancement.

Notable Quotes

• Tim Fernback – President & CEO: “The advancement of the RCL metallurgical processing technology is central to Temas' long‑term strategy… This capital‑light approach has the potential to create scalable, repeatable value while also enhancing the economics of our own projects.”
• David Caldwell – COO: “RCL represents a highly advanced and difficult‑to‑replicate solution… The results demonstrate that RCL can consistently produce high‑purity products under comparatively mild operating conditions, with materially lower operating costs and enhanced value creation through the capture of high‑value co‑products.”
