TEMAS PROVIDES UPDATE ON RCL METALLURGICAL LAB COMMISSIONING AND INITIATES LA BLACHE BULK SAMPLE TRANSFER

Temas Resources Corp. has provided shareholders with an update regarding the commissioning of its technology research and development centre (TRDC) metallurgical laboratory located in Ontario, Canada.

• Commissioning of Temas's technology research and development centre (TRDC) metallurgical laboratory is progressing as planned, with full operational status expected during July, 2026.
• Approximately 13 metric tonnes of previously assayed drill core material from the La Blache titanium-vanadium-iron project is being transferred to the TRDC for advanced metallurgical testing.
• Material originates from the Hervieux-East and Hervieux-West deposits and represents previously characterized mineralized material from historical drilling programs.
• Testing will support continued optimization of Temas's proprietary regenerative chloride leach (RCL) technology for titanium, vanadium and associated critical minerals.
• Results are expected to further support process optimization, commercialization initiatives and future project development at La Blache.

Following the successful establishment of the laboratory earlier this year, commissioning activities continue to progress on schedule and the facility is expected to become fully operational during July, 2026.

As part of the initial operating program, the company has initiated the transfer of more than 13 metric tonnes of previously assayed mineralized rock from its wholly owned La Blache titanium-vanadium-iron project in Quebec to the TRDC facility. The material was recovered from historical drilling completed on the Hervieux-East and Hervieux-West deposits and represents well-characterized mineralized material that will be used for future RCL metallurgical evaluation.

The planned testwork will allow the company to continue refining and optimizing the RCL process under controlled laboratory conditions while generating additional data to support future commercial applications of the technology.

Kyler Hardy, executive chairman of Temas, commented:

"The commissioning of our TRDC laboratory represents a significant milestone in the commercialization of the RCL technology platform. Beginning work on a substantial bulk sample from La Blache allows our technical team to further optimize the process using representative project material while continuing to advance the engineering data required for future development. Having these capabilities in-house provides greater flexibility, faster turnaround times, and strengthens our ability to support both our internal projects and third party commercial opportunities."

Tim Fernback, president and chief executive officer, commented:

"We are very pleased with the progress being made at the TRDC laboratory and remain on schedule for full operations during July. The movement of over 13 metric tonnes of previously assayed La Blache material to the laboratory marks the beginning of an important phase of technical development for both our flagship project and our proprietary RCL technology. As we continue demonstrating the versatility of the RCL platform across multiple feedstocks, this work will further strengthen our commercialization strategy while advancing the development of La Blache as a potential long-term source of critical minerals.

"This 13-plus metric tonne bulk sample represents one of the largest continuous RCL metallurgical testing campaigns undertaken by the company using representative La Blache project material, and is expected to generate valuable engineering and process optimization data for future commercial development."

The company expects the TRDC laboratory to become the primary centre for continued development of the RCL technology platform, supporting internal metallurgical programs, third party testing, process optimization, licensing opportunities and future pilot-scale initiatives.

The company will continue to provide shareholders with updates as commissioning activities are completed and metallurgical testing progresses.

RCL platform overview

Temas's proprietary regenerative chloride leach (RCL) technology is an advanced hydrometallurgical process designed to recover valuable metals from complex ores, concentrates, slags and mine tailings using an environmentally responsible, closed-loop process.

Key advantages of the RCL platform include:

• Lower operating temperatures and atmospheric pressure processing;
• Closed-loop reagent recycling designed to reduce operating costs and environmental impact;
• Enhanced recovery of titanium, vanadium, rare-earth elements and other critical minerals;
• Reduced processing complexity relative to many conventional metallurgical methods;
• Broad applicability across numerous mineral deposit types worldwide.

About Temas Resources Corp.

Temas Resources 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 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 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 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.

We seek Safe Harbor.
