• Matched 2026 re-assays show a material uplift in reported accessory critical metal grades relative to the original 2022 assays, with the mineralised oxide population returning increases of approximately 24% V₂O₅, 48% Cr, 12% Ga and 10% Sc when comparing the same 684 sample intervals, while Fe₂O₃ + TiO₂ remained broadly consistent between assay campaigns.

Mr. Tim Fernback, Temas Chief Executive Officer, commented:
"The 2022 re-assay results reinforce the scale and consistency of the Farrell-Taylor Fe-Ti-V oxide system and provide a stronger, internally consistent geochemical dataset for future resource and development work at La Blache. We will use these results to help guide the future deployment of our novel Regenerative Chloride Leach Technology, with testing to include the vanadium, gallium and scandium taken from this location."

Temas Resources Corp. ("Temas" or the "Company") (ASX: TIO | CSE: TMAS | OTCQB: TMASF | FSE: 26P0) is pleased to report significant intercepts generated from the 2026 re-assay of original 2022 drill pulps from the La Blache Project in Québec, Canada.

Table 1: Significant Drill Intercepts for 2022 Re-Assayed Drilling*

* Cut-off grades for massive oxide classification are 78% Fe₂O₃ + TiO₂ + ≤4.5% MgO, with internal dilution of 2.9m and minimum composite of 2.5m. Massive oxide classification requires a maximum of 4.5% MgO. Cut-off grades for semi-massive oxide classification and determination of a significant intercept are 20% Fe₂O₃ + TiO₂ + ≤4.5% MgO, with internal dilution of 2.9m and minimum composite of 2.5m. V₂O₅ (%) has been recalculated from V (ppm) using the ALS oxide conversion factor of 1.785 for V to V₂O₅.

The 2022 drilling was completed using NQ diamond core and targeted the Farrell-Taylor area of the La Blache Fe-Ti-V oxide system. The current results do not relate to new drilling; they relate to re-analysis of selected original 2022 pulps using the Company's preferred fused-bead assay protocol, combined with original 2022 assay data where required to fill internal gaps in the re-assay coverage.

The significant intercepts reported in Table 1 were calculated from the preferred re-assay dataset using length-weighted compositing. The table reports downhole intervals and does not imply true widths. All grades are length-weighted over the reported composite interval, including any internal dilution allowed under the stated criteria.

Drill Results Overview

The 2026 re-assay dataset confirms broad, high-grade Fe₂O₃ + TiO₂ intervals across the 2022 LB-series holes. The strongest width-grade combinations occur in LB-22-07, LB-22-09 and LB-22-06, with additional high-grade intervals reported in LB-22-01, LB-22-04, LB-22-05 and LB-22-08. LB-22-03 returned a narrower but high-grade intercept.

The mineralisation at La Blache is characterised by massive and semi-massive Fe-Ti-V oxide assemblages hosted within the La Blache Anorthosite Complex. For this announcement, the reported cut-off proxy is Fe₂O₃ + TiO₂ + capped MgO, with MgO capped at 4.5% in the cut-off calculation. Massive oxide classification requires both the ≥78% cut-off and a maximum MgO value of 4.5%; intervals that exceed the cut-off but have length-weighted MgO above 4.5% have been retained in the significant-intercept table and flagged as SMO for review.

Re-Assay Results Overview

To quantify the impact of the 2026 re-assay program, Temas compared only those samples where a direct one-to-one match exists between the original 2022 assay and the corresponding 2026 pulp re-assay. This comparison comprises 684 matched sample intervals, with all averages calculated on a length-weighted basis. Major oxide results were compared to a 2022 ME-ICP06 (fused bead digestion)/ ICP06 versus 2026 ME-ICP06 (identical fused bead digestion)/ ICP06 basis, while trace elements were compared on a 2022 ME-MS61 (4-acid digestion) versus 2026 ME-MS81 (fused bead digestion) basis.

As expected, the comparison between identical assay protocols indicates that the major oxide grades are broadly stable between assay campaigns. The trace metals also behaved as expected, with the uplift between the original 4-acid digestion and the near complete digestion of the fused bead protocol most pronounced within the MO domain, where matched samples increased from 0.37% V₂O₅ to 0.47% V₂O₅, 948 ppm Cr to 1,437 ppm Cr, 55 g/t Ga to 62 g/t Ga, and 17.6 ppm Sc to 19.5 ppm Sc. The SMO domain also returned consistent increases, with matched samples increasing from 0.22% V₂O₅ to 0.27% V₂O₅, 545 ppm Cr to 796 ppm Cr, 36 g/t Ga to 41 g/t Ga, and 15.0 ppm Sc to 16.4 ppm Sc. These results support the Company's view that the 2026 assay protocol provides an improved basis for quantifying accessory critical metals within the La Blache oxide mineralisation.

Next steps include continued integration of the 2022 re-assay data with the historical and recent drilling datasets, review of MO/SMO domaining, and assessment of implications for future resource work and technical studies.

A drill program is currently in design to test the western extent of Farell Taylor, as it's interpreted to extend to surface toward the Schmoo Zone.

ABOUT TEMAS RESOURCES

Revolutionizing Metal Production
Proprietary IP. Global Licensing. Titanium & Critical Minerals.

Temas Resources Corp. (ASX:TIO)(CSE:TMAS)(OTCQB:TMASF)(FRA:26P0) 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% lower than traditional processing - while dramatically reducing energy use and environmental impact.

Temas' 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% of two advanced titanium-vanadium-iron projects in Québec, Canada - La Blache and Lac Brûlé - 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.

Benefits of the ORF - RCL Technology:

The RCL platform technology involves the hydrometallurgical mineral extraction of concentrates, whole ores, slags and tailings to enhance recovery of critical metals, battery metals, Platinum Group Minerals ("PGMs"), precious and base metals and Rare Earth Element ("REE") recovery at materially higher through-yields and lower capital and operating costs than many of the conventional approaches that are in use traditionally. This novel RCL technology is ideally suited to treat increasingly complex ores in an environmentally sensitive manner.

Pilot Testing Complete: The Company has completed a pilot test of approximately 1 ton of material from its La Blache TiO₂ mineral property yielding 88 kgs of a 99.8% pure TiO₂ commercial grade product.¹

Validated Cost Reduction: A significant cost reduction of over 65%^2,3 is validated for TiO₂ processing using the RCL platform technology (e.g., reagent recycling, potentially lower energy use, optimized recovery etc.). These fundamental process efficiencies are expected to translate into economic advantages when applying the platform to Nickel or other target minerals hosted in complex ores.

Environmental Performance: The closed-loop design and high reagent recycling rates are core to the RCL platform, irrespective of the target mineral. Over 69% lower operating costs compared to conventional processing due to its core features operating at near ambient temperatures.³ This means the reduced environmental footprint and enhanced ESG profile are benefits that extend to ores and minerals previously noted, not just TiO₂.

High Recovery Potential: Just as we've demonstrated high-quality, 99.8% TiO₂ product from pilot testing¹ the RCL platform is engineered for high recovery and purity of all target metals. Our metallurgical expertise focuses on optimizing these recoveries and maximizing margins for each specific mineral.

RCL results in a quicker and more complete liberation of the target metals using atmospheric pressure and lower temperatures than competing methods and improves the selectivity and efficiency of subsequent solvent extraction steps. Management believes that this novel metallurgical process can be applied to many complex resource deposits worldwide, enhancing both extraction and recovery for the operator.
