29 December 2025 – Vancouver, Canada | Temas Resources Limited (ASX:TIO) (“Temas” or the “Company”) has today announced the completion of a high-resolution airborne LiDAR survey across its La Blache and Lac Brule Projects in Québec, Canada. This milestone will assist Temas in accelerating engineering, feasibility planning and the future development activities at each of the assets.
The survey covered ~46.05km2 and delivered engineering-grade topographic data beneath dense forest cover. The data provides a detailed digital elevation model suitable for geological and structural interpretation, mineral resource estimation, infrastructure design and environmental baseline studies.
The LiDAR dataset integrates with recently completed HQ diamond drilling programs at both La Blache and Lac Brule, as well as previous drilling campaigns, enabling refined geological, engineering and modelling outcomes. It is expected to streamline future drilling programs, fieldwork and infrastructure planning.
Assay results from the most recent drilling campaigns are also being processed, with initial results expected from January 2026. In parallel, Temas plans to reevaluate 181 historic drill holes totalling 36,614 metres for gallium and other rare earth element potential, with re-assay programs commencing in January of 2026 and results anticipated in March.
Historic and recent drill core will also support the ongoing development of Temas’ patented Regenerative Chloride Leach (RCL) processing technology, which targets up to 65 per cent cost reductions and improved recovery across critical metals. Initial test results are expected in early calendar year 2026. Discussions are also underway regarding third-party testing of gold, silver, nickel, rare earth elements and other critical minerals.
Tim Fernback, CEO, 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 dataset 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 optimisation and value creation.”
Mr. David Caldwell, Temas Chief Operating Officer, 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 10s of meters. In practice this newly acquired dataset 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 re-surveying program for the legacy handheld collar locations which can also have inaccuracies of up to 10s of meters. Together the sub-decimetre quality differential GPS 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 testwork for its proprietary Regenerative Chloride Leach platform technology.
Tim Fernback, CEO, of Temas also commented: “La Blache and Lac Brule hold compelling multi-element 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 datasets 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.”
Testing of the RCL technology using more than 40,000 metres of historic and recent drill core is expected to commence in January 2026, with initial results anticipated in February and March.
