NYSE - LSE
Temas Advances Commercialisation of Patented 'RCL' Metallurgical Processing Technology
Pilot-scale validation confirms commercial-grade TiO2 production, enhanced revenue capture through multi-metal recovery, material cost reductions and establishes a global licensing and partnership pathway.
Highlights
Temas is advancing its Regenerative Chloride Leach ("RCL") processing technology, an innovative platform for the recovery of critical and precious metals .
RCL platform comprises 11 granted process patents , 100% owned by Temas following the acquisition of ORF Technologies Inc. 1
Extensive bench-scale and pilot-scale metallurgical testing completed using mineralized material from the Company's 100% owned La Blache titanium-vanadium Project, Quebec have defined optimal operating conditions for TiO 2 and Fe 2 O 3 recovery .
Pilot-scale testing and associated process evaluation have independently demonstrated cost reductions of greater than 65% for TiO 2 processing relative to conventional methods, driven by co-product capture, closed loop reagent recycling, simplified flowsheets and reduced energy intensity 2 .
Key outcomes of the testing included 3 :
Processing of approximately 830 kg La Blache deposit material, producing 88 kgs of optimised ultra-low impurity TiO 2 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 Fe 2 O 3 product (> 99% pure) targeting high-end pigment and battery grade specifications.
Core from Temas's 2022 and 2025 drill programs (4,915m total), together with 36,844m of historic drill core, is currently being evaluated using the RCL platform, with additional metallurgical results expected from later this quarter, including a focus on Gallium and Scandium (previously overlooked).
The RCL technology is commodity-agnostic and scalable and is currently being evaluated by multiple third-party mining companies for applicability to treat complex mineral deposits, supporting potential licensing and joint venture opportunities.
VANCOUVER, BC / ACCESS Newswire / January 29, 2026 / Temas Resources Corp. (" Temas " or the " Company ") (CSE:TMAS)(ASX:TIO)(OTCQB:TMASF)(FSE:26P0) is pleased to provide an update on the advancement and commercialisation of its patented Regenerative Chloride Leach ("RCL") metallurgical platform.
As announced on October 30, 2025, Temas acquired 100% ownership of ORF Technologies Inc., securing a portfolio of eleven (11) granted patents covering a novel mixed-chloride hydrometallurgical processing platform developed over more than 50 years within a Government of Canada-funded research organisation. Temas refers to this platform technology as RCL.
The Company is advancing RCL as a standalone, technology-led business, intended to generate value through licensing, joint ventures and internal deployment, while also enhancing the economics of Temas' wholly owned titanium-vanadium projects in Quebec, Canada.
The Company views RCL as a scalable metallurgical platform with the potential to generate value through both internal application and external commercialisation across multiple commodities.
RCL Platform Overview
RCL is an innovative, advanced hydrometallurgical platform designed for the efficient extraction of metals from complex mineralization, concentrates, slags and tailings in an environmentally responsible manner.
Key attributes of the RCL platform include:
Ability to process low-quality feedstocks and render high-value end products.
Atmospheric pressure and lower-temperature operation relative to conventional chloride or sulphide routes.
Closed-loop reagent recycling delivering materially lower operating costs and reduced environmental footprint.
Enhance the recovery of critical metals, battery metals, platinum group minerals, precious and base metals and rare earth elements.

Pilot-Scale Validation and Metallurgical Results 3
Temas has completed extensive bench-scale and pilot-scale testing of the RCL platform using material from its La Blache titanium-vanadium project in Quebec, Canada.
Key outcomes include:
Processing of approximately 830 kg La Blache deposit material, producing 88 kgs of optimised TiO 2 powder grading 99.8% purity.
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 Fe 2 O 3 product (> 99% pure) targeting high-end pigment and battery grade specifications.
Pilot-scale testing and associated process evaluation have demonstrated operating cost reductions exceeding 65% for TiO 2 production relative to conventional processing routes. These efficiencies are driven by capture of high-value co-products, high reagent recycling rates, reduced energy consumption and simplified process flowsheets and are expected to translate across other commodities and deposit types.

Expanded Metallurgical Program and Near-Term Technology Catalysts for RCL Development
Temas is currently evaluating the HQ Core from the recently completed 2025 drill program4, as well as over 36,800 meters of historic drill core from previous drilling at La Blache, to further enable the optimisation and scale up of the RCL technology.
The material is undergoing further RCL metallurgical testing and optimisation to:
enhancing the recovery of vanadium (V 2 O 5 ) from the La Blache massive oxides; and
initiating process development for the recovery of Gallium (Ga) and Scandium (Sc) values in the Fe/Ti oxide mineralization at La Blache, which were not previously targeted.
The identification of Gallium and Scandium as critical and strategic minerals in North America has fostered an incentive to re-shore their production into North America. Temas recognises these additional critical and rare earth elements as a potential value enhancement to the La Blache Project and is initiating a program to optimize the recovery of Ga and Sc at La Blache.
This expanded metallurgical program is designed to further optimise recoveries, validate closed-loop circulation and benefits and broaden the application of the RCL platform beyond titanium into additional critical and strategic metals. Outcomes from this work are expected to directly inform both internal project development and external licensing discissions.
Initial results from this program are expected to be available later this quarter, with further updates anticipated into Q1 - Q2 2026.
Technology Commercialisation and Third-Party Evaluation
The RCL platform is currently being evaluated by multiple third-party mining and materials companies globally as a metallurgical solution for complex mineral deposits, with discussions progressing under confidentiality arrangements.
Companies are currently evaluating RCL for mineral processing operations include:
Indonesia (Ni/Co/Mg/Fe),
Australia (Au/Fe),
British Columbia, (Au/Ag/Zn/Pb), and
Ontario, Canada (TiO 2 /V/Mg/Fe)
These evaluations are focused on potential technology licensing and/or joint venture opportunities, reinforcing that the Temas RCL technology is not only key to unlocking the value of our own internally generated projects, but it has significant potential to enhance the extraction and recovery of many types of complex mineralised systems around the world.
4 ASX Announcement, 27 Nov 2025 - Temas Completes Drill Program Targeting Critical Minerals and Rare Earth Elements
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, technology-led 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."

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 commercialisation 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] 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.

Further work is required to confirm performance at commercial scale.
JORC Table 1 - Section 3
Metallurgical Factors or Assumptions
Criteria | JORC Commentary |
Sample selection and representivity | Metallurgical test work was undertaken on composite bulk samples of ilmenite ore sourced from the La Blache Project. The composite sample weighed approximately 830 kg and was prepared from 11 individual samples, however specific sample location is unknown. The material was homogenised using cone and quartering prior to test work. The samples are considered representative of the dominant mineralised material available for test work; however, they may not reflect the full range of grade or lithological variability across the deposit. |
Test work type | A staged metallurgical program comprising bench-scale test work, mini-pilot testing and large pilot plant operation was completed. Test work included two-stage chloride leaching, solid-liquid separation, oxidation, solvent extraction for iron and titanium, and thermal precipitation of titanium dioxide product. |
Scale of test work | Bench-scale leach tests were followed by a mini-pilot program and a large pilot plant operation processing approximately 830 kg of composite ore. Pilot circuits operated continuously for up to ~650 hours for iron solvent extraction and ~580 hours for titanium solvent extraction. |
Processing flowsheet | The processing route investigated comprises crushing and grinding, two-stage hydrochloric acid leaching, flocculation and filtration, oxidation, solvent extraction for iron removal, solvent extraction for titanium recovery, stripping, and thermal precipitation to produce TiO₂. |
Grinding and particle size | Leaching test work utilised feed material ground to approximately 90% passing 65 mesh. |
Leach conditions | Two-stage leaching was conducted at temperatures of approximately 70°C using hydrochloric acid (5.8 N) and magnesium chloride, with pulp densities of approximately 10-15%. |
Recovery factors | Average recoveries achieved during pilot operations were approximately: Ti 75-85%, Fe 93-95%, and V 99-100%. Recovery ranges varied between mini-pilot and large pilot phases. |
Product specification | The titanium solvent extraction circuit produced a titanium-rich strip liquor with average titanium concentrations of approximately 33 g/L, which was subsequently thermally precipitated to produce TiO₂ product. Approximately 90 kg of TiO₂ product was generated during pilot operations. |
Mass balance and recoveries | Material balances were calculated for leaching and solvent extraction circuits based on solution assays and solids analysis. Recoveries are indicative only and subject to analytical and operational variability. |
Impurities and deleterious elements | Impurity build-up was monitored during pilot operation, including aluminium, calcium, magnesium, manganese, sodium, chromium and sulphur. Scrubbing stages in the titanium solvent extraction circuit were used to reduce impurity levels in final product streams. |
Metallurgical domains | No discrete metallurgical domains have been formally defined. Test work was conducted on a single composite sample representing available bulk material as a preliminary assessment of project material extractability. Variability testing has not yet been completed. |
Process optimization | The flowsheet represents a conceptual process route derived from laboratory and pilot-scale testing. Further optimisation and variability test work is required prior to commercial design. |
Reagents | Hydrochloric acid, magnesium chloride, organic extractants, ammonia for precipitation, and flocculants were used during test work. Reagent consumptions were not optimised for commercial operation. |
Environmental considerations | Environmental, permitting, tailings management and waste disposal considerations have not been assessed as part of the metallurgical program. |
Infrastructure requirements | Infrastructure assumptions, power requirements and water balance have not been assessed at a project scale. |
Commercial status | The metallurgical test work is at laboratory and pilot scale only and does not constitute a feasibility study. Results are indicative and subject to scale-up risk. |
Economic implications | The metallurgical results do not imply economic viability and should not be interpreted as demonstrating commercial or economic extraction. |
Limitations | The results are based on composite material and limited variability. Further metallurgical variability test work is required to assess performance across the full deposit. |
Recovery assumptions for resources | No modifying factors have been applied to any Mineral Resource estimate based on this metallurgical work. |
