Re-Assay Program Validates Extensive High-Grade Mineralisation
Temas Resources (ASX:TIO) has delivered compelling early results from its systematic re-assay program at the Hervieux West deposit within its 100%-owned La Blache Titanium-Vanadium Project in Québec. The program confirms extensive, high-grade titanium-vanadium-iron oxide mineralisation across a large and thick mineralised body, reinforcing confidence in the continuity and scale of the deposit.
Using Temas’ preferred fused-bead analytical method, the re-assays also reveal significant concentrations of critical minerals gallium, scandium, and chromium. These findings not only validate historical data but also expand the project’s critical mineral credits, potentially adding incremental economic value.
Historic Drill Core Recovery Accelerates Technical Progress
A strategic advantage underpins this progress: Temas has successfully recovered over 36 kilometres of historic drill core from previous campaigns. This enables wholesale re-assay and geological review without the costly and time-consuming need for replacement drilling, materially accelerating technical studies and reducing exploration risk.
The recovered core spans 60 drill holes totaling approximately 9,352 metres, drilled on a nominal 50-metre spacing. The initial 32 holes re-assayed focus on the deposit margins to delineate the massive oxide (MO) and semi-massive oxide (SMO) domains, setting the stage for a comprehensive geological model and future resource estimation.
Critical Minerals and Proprietary Processing Technology
Temas’ proprietary Regenerative Chloride Leach (RCL) platform technology stands to benefit from the expanded critical mineral dataset. The presence of gallium, scandium, and chromium alongside titanium and vanadium informs metallurgical optimisation and guides extractive metallurgy development. This aligns geology with metallurgy, potentially enhancing recovery rates and project economics.
The RCL platform has previously demonstrated over 65% cost reductions compared to traditional processing methods, validated through pilot testing of La Blache material. The new assay data will underpin ongoing metallurgical testwork, including large-scale processing trials at Temas’ Ontario lab, nearing full commissioning in July 2026.
Significant Drill Intercepts Highlight Scale and Grade
Noteworthy intercepts from the Hervieux West re-assay include:
- 143 metres at 88.7% combined Fe₂O₃ and TiO₂, 0.48% V₂O₅, 1,431 ppm chromium, 60.5 g/t gallium, and 19.2 ppm scandium
- 27.3 metres at 88.2% Fe₂O₃ + TiO₂, 0.44% V₂O₅, 786 ppm chromium, 57.6 g/t gallium, and 19.2 ppm scandium
- Multiple other intercepts exceeding 80% Fe₂O₃ + TiO₂ with consistent critical mineral grades
These results confirm the deposit’s robust mineralisation and provide a reliable basis for future resource modelling and engineering studies.
Advancing Towards Resource Updates and Development
Temas is progressing geological domaining and interpretation, integrating the enhanced assay dataset into updated resource models. The company anticipates completing the Hervieux West re-assay program shortly and commencing re-assays at the Hervieux East deposit. These steps will feed into a maiden JORC-compliant Mineral Resource Estimate and underpin future engineering evaluations.
CEO Tim Fernback emphasised the strategic significance of these results, noting the project’s potential as a critical North American source of titanium, vanadium, and other strategic minerals. COO David Caldwell highlighted the consistent high-grade nature of the massive oxide mineralisation and the opportunities to extend mineralisation along strike and at depth.
Next Steps Include Metallurgical and Resource Development
Temas plans to finalize commissioning of its metallurgical laboratory in Ontario, complete remaining re-assays, and integrate new data into geological and resource models. The company aims to advance technical studies that support resource updates and development planning for one of North America’s largest undeveloped titanium-vanadium systems.
The combination of a substantial mineral resource with a proprietary, cost-effective processing platform positions Temas Resources to meet growing demand for secure Western supplies of critical minerals.
Bottom Line?
Temas Resources’ re-assay results at La Blache reinforce the project's high-grade mineralisation and critical metal potential, setting a clear path toward resource updates and metallurgical optimisation with proprietary technology.
Questions in the middle?
- How will pending assay results from Hervieux West and Hervieux East refine the resource model and critical mineral credits?
- What impact will the expanded critical mineral dataset have on the economics and scalability of Temas’ RCL processing technology?
- To what extent can mineralisation be extended along strike and at depth, and how will this influence future drilling strategies?
