TEMAS EXPANDS SCIENTIFIC ADVISORY BOARD WITH APPOINTMENT OF CHEMICAL PROCESS DEVELOPMENT EXPERT, DR. SANTIAGO FAUCHER

Temas Resources Corp. has appointed Dr. Santiago Faucher to its scientific advisory board (SAB), further strengthening the company's technical and commercialization capabilities as it advances its proprietary regenerative chloride leaching (RCL) technology.

Highlights:

• New scientific advisory board appointment: Dr. Faucher, a Toronto-based chemical and metallurgical process expert, has been appointed to Temas Resources' scientific advisory board (SAB);
• World-class technical leadership and experience: Dr. Faucher brings over 30 years of experience in process development, commercialization and scale-up across mining, metallurgical and chemical industries;
• Relevant technical expertise: Dr. Faucher also has extensive expertise in areas that are crucial to Temas's RCL technology, including critical minerals processing, hydrometallurgy and complex feedstock optimization.
• Commercialization-ready scientific leadership: appointment further enhances the Temas SAB's capability to support global deployment and the commercialization of its proprietary RCL technology;
• Intellectual property and protection for proprietary platform technology: Temas's 100-per-cent-owned RCL technology platform comprises granted process patents, covering the extraction of multiple metals and feedstocks, including, but not limited to, refractory gold, titanium, polymetallic sulphides, nickel laterite, critical minerals and rare earths.

Dr. Faucher is a Toronto-based highly accomplished chemical engineer and process development expert with more than three decades of experience in developing and commercializing industrial technologies across the mining, metallurgical, polymer, coatings, cement and biomass sectors. Dr. Faucher has a proven record of advancing new chemical and metallurgical technologies from laboratory innovation through to full-scale industrial implementation, with previous successful deployments across five continents.

Dr. Faucher currently serves as president of Insight R&D Inc., where he leads the development and deployment of advanced process technologies for mining and metallurgical clients. His work includes the development of uranium extraction processes, base metal recovery systems, slag valorization technologies and chemical production processes, with a strong focus on complex ores and unconventional processing routes.

Dr. Faucher holds a BSc and PhD in chemical engineering from leading Canadian universities and is an inventor on more than 60 U.S. patents, many of which have been successfully commercialized. Dr. Faucher has also written numerous technical publications as well as previously served as president of the Canadian Society for Chemical Engineers and as an adjunct professor at McMaster University.

Commenting on the appointment of Dr. Faucher, Tim Fernback, president and chief executive officer of Temas Resources, stated: "We are very pleased to welcome Dr. Faucher to our scientific advisory board. His extensive experience in process development, hydrometallurgy and commercialization at a global scale will be instrumental to Temas as we continue to advance and deploy our RCL technology. Dr. Faucher's ability to bridge innovation and industrial implementation aligns perfectly with our strategy to accelerate adoption of RCL across a broad range of mineral applications."

As a member of the SAB, Dr. Faucher will provide independent technical guidance to Temas's management team, supporting process optimization, scale-up strategies, and the evaluation of third party mineral feedstocks for potential licensing and joint venture opportunities. The appointment of Dr. Faucher further enhances the Temas SAB's depth of expertise in hydrometallurgy as well as reinforces company's commitment to scientific rigour and technical excellence in the development of its technology.

The company continues to build a world-class scientific advisory board to support the advancement and global deployment of its RCL platform, with additional appointments expected in the coming months.

RCL platform overview and competitive differentiation

Temas's RCL platform is an innovative, advanced hydrometallurgical platform designed for the efficient extraction of metals from complex mineralization, 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;
• Enhanced recovery of critical metals, battery metals, platinum group minerals, precious and base metals, and rare earth elements.
