Temas Resources Limited has advanced the commercialization of its patented Regenerative Chloride Leach (RCL) metallurgical processing technology, following successful pilot-scale validation that confirms the production of commercial-grade titanium dioxide (TiO2), significant operating cost reductions and enhanced multi-metal recovery.
The RCL platform is an innovative hydrometallurgical processing technology designed to extract critical, battery, precious and base metals from complex mineralized feedstocks. Temas owns 100 % of the technology and its associated intellectual property, comprising 11 granted process patents, following the acquisition of ORF Technologies Inc. in October 2025.
Extensive bench-scale and pilot-scale metallurgical testing has now been completed using mineralized material from Temas’ 100 % owned La Blache titanium-vanadium project in Quebec, Canada. The testing program defined optimal operating conditions for the recovery of TiO2 and iron oxide (Fe2O3), while independently demonstrating operating cost reductions of greater than 65 % for TiO2 processing compared with conventional methods.
Key outcomes of the testing included:
- Processing of approximately 830 kg La Blache deposit material, producing 88 kgs of optimized ultra-low impurity TiO2 powder grading 99.8 %.
- Two-stage leach yielding 80-85 % titanium recovery and ∼95 % iron recovery, with further improvements expected through scale-up and closed-loop circulation.
- Solvent strip extraction demonstrates rapid and selective separation, removing 99.9 % of iron from solution.
- Planned pyrohydrolysis testing to yield a premium Fe2O3 product (> 99 % pure) targeting high-end pigment and battery grade specifications.
Mr. Tim Fernback, Temas Chief Executive Officer commented:
“The advancement of the RCL metallurgical processing technology is central to Temas’ long-term strategy. Alongside our existing critical mineral assets in North America, we are building a standalone, technologyled business focused on licensing, partnerships, and joint ventures with a strategy to expand our global presence in the world of advanced metallurgical processing.
This capital-light approach has the potential to create scalable, repeatable value while also enhancing the economics of our own projects, which serve as feedstock for the continued development and validation of our processing technology.
As RCL continues to demonstrate its applicability across multiple commodities deposit types, it provides Temas with multiple pathways to growth and value creation.”
Mr. David Caldwell, Temas Chief Operating Officer commented:
“The RCL metallurgical platform represents a highly advanced and difficult to replicate solution that has been developed and refined over several decades. What differentiates RCL is not only the depth of Intellectual Property, but the level of demonstrated pilot-scale validation achieved across several deposit types and commodities.
These 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. This combination of technical maturity, economic performance, and scalability positions RCL as a genuinely commercial platform rather than an experimental process.”
The RCL technology is commodity-agnostic and scalable, with its closed-loop reagent recycling, simplified flowsheets and lower energy intensity contributing to materially lower operating costs and a reduced environmental footprint. Beyond titanium, Temas is evaluating the application of RCL to additional critical and strategic metals, including vanadium, gallium and scandium, which were previously overlooked within the La Blache mineralization.
Core from Temas’ 2022 and 2025 drill programs, totalling 4,915 meters, together with 36,844 meters of historic drill core, is currently being evaluated using the RCL platform. Additional metallurgical results are expected later this quarter, with further updates anticipated into the first half of 2026.
In parallel with internal development, the RCL platform is being evaluated by multiple third-party mining and materials companies globally for its applicability to complex mineral deposits. These evaluations, which are progressing under confidentiality arrangements, span projects in Australia, Indonesia, British Columbia and Ontario, and are focused on potential technology licensing and joint venture opportunities.
