TEMAS ADVANCES DRILL PROGRAM AT LA BLACHE, QUEBEC, TARGETING TITANIUM & CRITICAL MINERALS RESOURCE GROWTH

Temas Resources Corp. has made progress in its 2,500-metre diamond drilling campaign at its La Blache property in Quebec, Canada.

Approximately 1,000 m have been completed to date, with drilling expected to continue through the third week of November. Results from this campaign will refine the geological model, expand the existing inferred resource and support the development of a maiden Joint Ore Reserves Committee-compliant mineral resource estimate during 2026.

Tim Fernback, chief executive officer of Temas Resources, commented: "Our current drilling program at La Blache is progressing on schedule, and early observations confirm strong geological continuity across the mineralized zones. We are building a strong foundation for Temas's next stage of value creation with resource expansion and integration on our RCL processing technology, which, together, position the company to deliver a competitive advantage in the titanium and critical minerals recovery market."

David Caldwell, Temas chief operating officer, commented: "La Blache is ideally located near existing infrastructure, a skilled regional work force and the deepwater Port of Saguenay. Beyond titanium and vanadium, we continue to identify promising signatures of scandium and gallium, offering additional upside. There is a push for onshoring critical metals and rare earth elements in North America, and adding scandium and gallium mineralization just adds to our world-class massive oxide deposit as we work towards defining our global mineral resource estimate at La Blache.

"Drill core from this program will also provide key metallurgical samples to advance the next phase of our RCL metallurgical technology development."

This fall/winter program will covers the full 2.5-kilometre mineralized corridor from Hervieux West to Farrell-Taylor, with drill holes positioned at 50-metre-by-50-metre intervals. Phase 1 is under way, with phase 2 scheduled for completion in early 2026.

The drill campaign is fully financed by the company's recent financings, and all drill permits and work authorizations are in place at La Blache. Upon completion, Temas will undertake full core analysis and assay testing to inform both its geological model and the design for its regenerative chloride leach pilot studies.

About Temas Resources Corp.

Temas Resources is a technology-driven critical mineral company advancing a dual-business model built around proprietary processing innovation and strategic mineral ownership. The company's patented regenerative chloride leach technology platform delivers significant operational cost reductions -- validated at up to 65 per cent lower than traditional processing -- while dramatically reducing energy use and environmental impact.

Temas's RCL process is the foundation of its technology licensing and partnership business, enabling global mining and material 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 per cent of two advanced titanium-vanadium-iron projects in Quebec, Canada -- La Blache and Lac Brule -- 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.
