He has held Managing Director and CEO roles across multiple listed entities and brings deep experience in capital markets, project development, strategic acquisitions and stakeholder engagement.

He has previously served as Managing Director and CEO of ASX-listed resources companies, where he led successful capital raisings, advanced mineral projects from early stage through to development, and worked closely with investors, analysts and strategic partners. He is currently a Non-Executive Director of Adavale Resources Limited (ADD) and Vice-President – Corporate Development at Red Mountain Mining (RMX).

In addition to his executive leadership background, Mr. Matich has extensive experience in business development and stakeholder engagement across the resources sector. In his role as Non-Executive Director, he will work closely with the CEO and Board to support investor relations, strategic partnerships and commercial discussions related to the Company's proprietary processing technology and critical minerals portfolio.

Mr. Matich holds an engineering and science degree from the University of Western Australia, a Graduate Diploma of Finance, and is a Graduate of the Australian Institute of Company Directors.

Mr. Tim Fernback, Temas Chief Executive Officer, commented:

"Nic's appointment as Non-Executive Director materially strengthens Temas' leadership team as we move into an execution and commercialisation phase.

Nic brings a strong capital markets, projects and business development experience, which is highly relevant as we commercialise our Regenerative Chloride Leach technology and advance our integrated critical minerals portfolio.

I would also like to acknowledge David Robinson’s continued leadership as CFO. David’s transition from the Board to a fully executive role sharpens our governance structure and ensures a strong focus on financial discipline and execution as the Company scales."

Mr. Nic Matich, Non-Executive Director, commented:

"I am very pleased to join the Board of Temas Resources. With the company's impressive portfolio of North American titanium and vanadium projects and the potential of the proprietary RCL technology to transform the economics of mineral extraction globally, there is a clear pathway for significant value creation for Temas shareholders. I look forward to supporting the management team as we advance our exploration programs and validate our world-class metallurgical processes."

ABOUT TEMAS RESOURCES

Revolutionising 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 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 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 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.

² These metallurgical test results and cost-reduction data were first reported in the Company’s Canadian market announcement dated 13 April 2021, titled “Temas Resources Acquires 50 % of Green Mineral Process Developer ORF Technologies Inc.”

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.

COMPARISON OF ORF-RCL PROCESS FOR TITANIUM PRODUCTION

3 Cheaper and more energy efficient:

A University of Minnesota study on ORF Technologies’ patients concluded that the TiO₂ recovery process, a two-step production costs by ~30-65%, and the presence in all natural energy resources compared to the industry standard.

4 Massive vector-talkelosis:

The determination for TiO₂, essential biSER23 oil on, is anticipated to grow at a compound annual growth rate of 6.2% through 2002, signify n₂-s substantial opportunity for ORF Technologies’ efficient recovery process.

5 Our technology as a platform:

ORF Technologies’ patented process can produce high-quality Titanium Dioxide (TiO₂) from low-grade materials and is applicable to all imprints cost, including those rich in Chromium (Cr), Cobalt (Co), and Vanadium (V), thus enabling the extraction of additional value from elements that are typically not recoverable with other methods.
