NEW LIDAR SURVEY COMPLETION ACCELERATES PLANNING AND ENGINEERING WORK AT LA BLACHE AND LAC BRULE

Temas Resources Corp. has received survey data from an airborne lidar (light detection and ranging) survey at the La Blache and Lac Brule properties in Quebec, Canada. This data set provides detailed topographic and structural information critical to future planning, engineering interpretation and environmental baseline work at both projects.

Highlights:

• Approximately 46.05 square kilometres of high-resolution airborne lidar survey completed at both La Blache and Lac Brule projects, delivering engineering-grade topographic data suitable to support future engineering and feasibility studies planning;
• Lidar survey integrates with recently completed HQ diamond drilling at both La Blache and Lac Brule, together with previous drilling campaigns, enabling refined geological, engineering and modelling;
• Lidar will expedite future drilling programs, fieldwork and infrastructure planning;
• Assay results from the recently completed drilling campaigns are being processed, with initial results expected to flow from January, 2026;
• 181 historic holes (36,614 metres) will be re-evaluated for gallium and other rare earth elements (REEs) potential, with reassay programs commencing January, 2026, and results expected in March, 2026;
• Preliminary indications from historical data review suggest potential for gallium and scandium; however, no reportable exploration results for these elements are available at this stage, and further analytical work is required;
• Historic and recent drill core will support the development of Temas's patented regenerative chloride leach (RCL) technology, targeting up to 65 per cent in cost reductions and enhanced recovery across critical metals, with initial test results expected in early calendar year 2026;
• Discussions regarding third party testing of gold, silver, nickel, REEs and critical minerals are well under way and the company expects to be able to update the market on these throughout the new year.

The primary objective was to generate a high-quality digital elevation model (DEM) beneath thick forest cover, suitable for geological mapping, structural interpretation, mineral resource estimation (MRE), engineering planning and permitting. Lidar is a high-resolution, laser-based mapping technique that generates a detailed three-dimensional point cloud of terrain surface.

The lidar data set will contribute to multiple technical activities, including:

• Enhanced geological and structural modelling;
• Refinement of planned infrastructure layouts;
• Identification of hydrological features and surface conditions;
• Prioritization of exploration targets and drill vectors;
• Support for environmental permitting baseline work.

Tim Fernback, chief executive officer of Temas Resources, commented: "The completion of this high-resolution lidar survey provides us with an exceptionally detailed view of the terrain across both La Blache and Lac Brule. This rich data set materially strengthens our technical foundation for future work, including drill targeting, engineering planning and environmental baseline studies. It further positions Temas to integrate all geological and structural data as we progress toward next-generation project optimization and value creation."

David Caldwell, chief operating officer of Temas, commented:

"Lidar at La Blache gives us a much sharper and more accurate state-of-the-art bare-earth surface at the decimetre level, which fundamentally upgrades our spatial foundation for everything compared to the coarse government DEM, which could have inaccuracy due to tree cover and smoothing of up to tens of metres. In practice, this newly acquired data set will become the master topographic control for environmental, permitting, geological modelling, targeting, resource modelling and engineering, pit design, haul road layout and pit slopes for each of the deposit areas at La Blache. We have also engaged a resurveying program for the legacy hand-held collar locations, which can also have inaccuracies of up to tens of metres. Together the subdecimetre-quality differential GPS [Global Positioning System] and the new lidar coverage comfortably bring our spatial accuracy, precision and understanding to the level required by feasibility-level work on this world-class vanadium titanomagnetite (VTM) resource at La Blache."

With drilling now complete, Temas will undertake a comprehensive drill core analysis and assay program to refine its geological model and advance metallurgical test work for its proprietary regenerative chloride leach (RCL) platform technology.

Tim Fernback, chief executive officer of Temas, commented: "La Blache and Lac Brule hold compelling multielement potential, and integrating our proprietary RCL processing technology into our development work enhances the long-term value of both projects. Early observations of gallium and scandium alongside titanium and vanadium broaden potential revenue streams and provide additional data sets to inform our RCL advancement.

"Temas plans to both license and joint venture the use of this technology internationally now that it has been shown to assist in developing metallurgically complex gold, silver, nickel, critical mineral and rare earth element deposits. We look forward to progress across geochemistry, metallurgical testing and technology validation in early 2026."

Regnerative chloride leach technology update

Drill core from the current and historic program totalling over 40,000 metres will be used to further refine RCL technology development. Testing is expected to commence in January, 2026, with initial results anticipated in February and March, 2026. RCL is central to unlocking value of the company's projects and has significant potential application across complex mineralized systems globally. Discussions regarding third party testing of gold, silver, nickel, REEs and critical minerals are well under way and the company expects to be able to update the market on these throughout the new year.

Temas has now been approached by several third party companies to bench test their deposits for potential RCL application.
