LETTER FROM THE CEO TO OUR SHAREHOLDERS:

Dear Shareholders,

"The fourth quarter ending December 31, 2025 was a transformative one for Temas with its listing on the ASX and concurrent financing of $11,000,000 AUD. This has set up the Company to execute on its strategy of developing its RCL technology and flagship La Blache titanium and vanadium critical minerals project in Québec, Canada. We are encouraged by the growing level of external interest in Temas, including the initiation of research coverage by Pitt Street Research.

Temas has been able to closely track is expenditure alongside its proposed budget in the Use of Proceeds section of the ASX IPO prospectus without material variance, with the one exception of shifting Lac Brule related expenditures to focus on the Company's flagship property La Blache to take advantage of new opportunities at La Blache that would materially increase overall shareholder value.

As described in our IPO Use of Proceeds:

• During Q4 Temas acquired the remaining 50% of ORF Technologies Ltd, which holds a series of innovative RCL patents that enhance the recovery of critical and precious minerals.

• Temas also completed a 2,300m drill program on La Blache and is currently completing the assays on the drill core along with re-assaying approximately 36,000 meters of historic drill core targeting Gallium, Scandium and other critical mineral and rare-earth elements which will ultimately expand and upgrade the inferred resource of the La Blache project.

• Additional expenditures as referenced in our ASX IPO Use of Proceeds include approx. $166,000 CAD spent in calendar 2025 for Metallurgical Testing and Metallurgical IP Development, which also includes the hiring of new RCL Metallurgical Staff.

Significant financial highlights from Q4 include:

• Completed its listing on the ASX and raised $11,000,000 AUD

• Completed the acquisition of the remaining 50% of ORF Technologies Ltd. as outlined in the ASX IPO Use of Proceeds, now owning 100% of the RCL Patented Platform technology

• Incurred $2,800,000 CAD in exploration expenditures during Q4, primarily on its 2,300m drill program at La Blache and as outlined in the ASX IPO Use of Proceeds

• Cash on hand of $4,700,000 CAD as of December 31, 2025

• Approximately $1,200,000 CAD in Quebec government tax credits available to Temas in 2026

• The successful exercise of all remaining Temas warrants and options would yield approximately $2,167,000 CAD in additional capital to the company.

• Quarterly G&A stabilized at $375,000 CAD in Q4 2025.

Temas' Regenerative Chloride Leaching (RCL) Technology - A Metallurgical Game Changer

We would like to begin by highlighting what we believe is one of the most significant value drivers for Temas, our proprietary Regenerative Chloride Leach ("RCL") technology.

We have made significant advancement over a very short period of time since we acquired 100% rights to the RCL technology. This including the signing two agreements within the first calendar quarter of 2026, generating the first Temas revenue for RCL testing services on third-party mining projects. Similarly in Q1 2026, we announced the formation of the Company's RCL Scientific Advisory Board and secured a location for the Temas RCL Metallurgical lab, a location to both service our RCL clientele and carry out the required engineering work associated with the scale-up of the technology.

For 2026 and beyond, it is the intention of the Company is to continue to test RCL in both a lab and pilot settings with third parties, ultimately creating both a stable and growing income stream through licensing and joint-venture projects. Management believes that we are well on our way to achieving this goal.

Our RCL technology, acquired through 100% ownership of ORF Technologies Inc., consists of 11 granted patents and represents decades of metallurgical research and development. This technology has been successfully pilot tested by different run-of-mine and mine tailings operators and has been shown to be effective with the extraction of feedstocks containing Refractory Gold, Titanium, Polymetallic Sulphides, Nickel Laterite, Critical Minerals and Rare Earths.

RCL is an advanced hydrometallurgical process designed to extract metals from concentrates, whole ores, slags, and tailings in a more efficient and environmentally responsible manner. What differentiates this platform-and positions it as a true industry disruptor-is its ability to fundamentally improve both economics and sustainability in metal production.

Recent pilot-scale validation using material from our La Blache project has demonstrated:

• Production of commercial-grade titanium dioxide (TiO₂) at 99.8% purity¹

• Operating cost reductions of greater than 65%^2,3 compared to conventional processing methods

• Strong recovery rates, including 80-85% titanium recovery and ~95% iron recovery¹

These results are highly significant in an industry where processing costs and technical complexity have historically been major barriers to developing titanium projects.

Beyond cost advantages, RCL introduces several key innovations:

• A closed-loop system that regenerates reagents, significantly reducing waste and environmental impact

• The ability to process lower-grade and more complex ores, unlocking value from deposits previously considered uneconomic

• Multi-metal recovery capability, enabling extraction of titanium, vanadium, nickel, rare earth elements, and other critical minerals from a single feedstock

Importantly, RCL is commodity-agnostic and scalable, and is currently being evaluated by multiple third-party mining companies globally for potential licensing and joint venture opportunities. This creates a pathway for Temas to generate non-dilutive revenue streams through technology deployment, independent of its own mining operations.

From a strategic perspective, RCL aligns directly with the evolving needs of modern critical mineral supply chains. As governments and industries prioritize cleaner, more efficient processing methods, the ability to produce high-purity products at lower cost and with a reduced environmental footprint becomes increasingly important.

We believe RCL represents a step-change in metallurgical processing, comparable to past innovations that have reshaped entire commodity sectors. By integrating this technology with our Québec-based projects, Temas is uniquely positioned to deliver a fully integrated, mine-to-market solution for critical metals in North America.

Unlike traditional mining companies, Temas is advancing a dual business model-combining resource development with a scalable, technology-driven processing platform.

Strategic Positioning in Critical Minerals Markets

Temas is advancing its portfolio of Titanium, Gallium, Vanadium and other critical mineral assets with the objective of becoming a reliable North American supplier. Our strategy is centered on:

• Developing environmentally responsible extraction and processing technologies

• Advancing high-quality critical mineral projects

• Aligning with Western supply chain security initiatives

We believe that ESG-compliant critical mineral production will be a key differentiator, particularly as governments and major industrial buyers increasingly prioritize sustainable and traceable supply chains.

Corporate Outlook and 2026 Priorities

As we move through 2026, Temas will focus on:

• Continue to commercialize RCL, generating both revenue and ultimately income streams for Temas

• Evaluating downstream RCL processing opportunities with existing mine operators

• Advancing exploration and development of its titanium, vanadium, gallium and other critical mineral assets in Québec

• Strengthening strategic partnerships aligned with defense and industrial supply chains

• Maintaining disciplined capital allocation to support long-term growth

Our goal is to position Temas as a key participant in the North American critical mineral supply chain, delivering value to shareholders while contributing to critical infrastructure and national security priorities.

Closing Remarks

The global narrative around critical minerals is evolving. While electrification remains important, the increasing emphasis on defense readiness, industrial resilience, and supply chain sovereignty is reshaping capital flows and strategic priorities.

We believe Temas and its RCL platform technology is well-positioned to benefit from this transition.

On behalf of the Board of Directors, I would like to thank our shareholders for their continued support as we advance our strategy in this rapidly changing environment.

Sincerely,

Tim Fernback
President & CEO
Temas Resources Corp.

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. [1]

Validated Cost Reduction: A significant cost reduction of over 65%[2]^,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.[3] 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.
