VANCOUVER, BC / ACCESS Newswire / February 17, 2026 / Temas Resources Corp. ("Temas" or the "Company") (ASX:TIO)(CSE:TMAS)(OTCQB:TMASF)(FSE:26P0) is pleased to announce a Letter of Intent ( "LOI") with 1542642 B.C. Ltd. a private mineral developer (the "Developer") to undertake funded testing of Temas' patented Regenerative Chloride Leach ("RCL") metallurgical platform technology on ore from the Developer's Revel Ridge polymetallic gold-silver project (3.0Moz @ 6.4g/t AuEq).

RCL Platform Overview

RCL is an innovative, advanced hydrometallurgical platform designed for the efficient extraction of metals from complex mineralisation, 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, and

  • Enhance the recovery of critical metals, battery metals, platinum group minerals, precious and base metals and rare earth elements.

The LOI sets out a staged testwork and commercialization pathway intended to 1) validate RCL on a refractory gold system and 2) if successful, progress to a future Joint Venture ("JV") for the deployment and commercialization of RCL in Western North America, including refractory gold and tailings opportunities.

The LOI is broken into 3 distinct phases with clear technical and commercial milestones, meaningful project milestones: bench-scale testing, pilot-scale testing, and potential progression toward a demonstration-scale processing facility, subject to results and agreement between the parties. Progression to Phase 2 will be forming a Joint Venture (the "JV") between Temas and the Developer to deploy the RCL process commercially in Western North America and specifically on refractory gold and tailings projects.

Refractory Gold Opportunity
The Developer's predecessors contemplated a Pressure Oxidization ("POX") processing route for the deposit. Temas believes RCL to potentially to complement, or subject to testwork outcomes, may have potential to replace elements of conventional routes by improving recoveries of the gold and significantly the silver, and enabling recovery of additional co-product while reducing the quantity and reactivity of tailings.

While initial testing will include evaluation of enhanced recovery of secondary metals, such as silver, zinc and lead, the program will take a holistic assessment of RCL as the potential primary processing option, subject to results.

Terms of the Letter of Intent:

Phase 1 - Technical & Business Development Work

  • The Developer's Commitments at its sole cost and before the end of summer 2026:

    • Bench-scale testing of the RCL Technology on Revel Ridge material.

    • Pilot-scale testing following successful bench scale outcomes.

  • Temas Business Development

    • Business development activities undertaken by Temas in a defined region of Western North America during Phase 1 will, if the Parties proceed to Phase 2, be attributable to the JV on a cost recovery basis from the election point forward.

Phase 2 - Formation and Funding of Joint Venture
Upon completion of the Phase 1 program and upon the receipt of results, Temas and the Developer shall enter further discussions to consider establishing the formation of a Joint-Venture & Funding package. The proposed Phase 2 program is non-binding at subject to both parties securing definitive terms of engagement. The LOI outlines;

  • Formation of an 80/20 Joint (in favor of Temas), terms of which are to be negotiated by both parties in good faith.

    • The JV's purpose to fund and advance the RCL technology platform to commercial status, including.

      • testing on third-party mineral projects, deposits and tailings; and

  • Pursuing commercial deployment primarily focused on refractory ores and complex feedstocks.

  • Indicative Terms ("the Developer"):

    • Invest CAD$2,000,000 into the JV upon election to proceed;

    • Appoint two members to the JV management committee.

  • Indicative Terms ("Temas"):

    • Exclusively deploy the RCL platform in Western North America through the JV;

    • Appoint 3 members to the JV management committee;

    • Operate the JV.

Phase 3 - Deployment & Project Development
Subject to JV formation and funding, the JV would seek to:

  • Deploy the RCL technology directly on projects within Western North America;

  • Acquire assets suitable for technology deployment;

  • Establish special purpose vehicles ("SPVs") for project development or deployment of the Technology or related assets.

The parties agree to deal exclusively with each other and negotiate in good faith towards a definitive agreement.

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 TiO2 mineral property yielding 88 kgs of a 99.8% pure TiO2 commercial grade product.2

Validated Cost Reduction: A significant cost reduction of over 65%3 is validated for TiO2 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.4 This means the reduced environmental footprint and enhanced ESG profile are benefits that extend to ores and minerals previously noted, not just TiO2.

High Recovery Potential: Just as we've demonstrated high-quality, 99.8% TiO2 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.

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.
