TEMAS COMMENCES RCL VANADIUM EXTRACTION TESTWORK AT LA BLACHE

Following the relogging on 36,614 metres of historic drill core from Temas Resources Corp.'s Farrell Taylor, Hervieux West and Hervieux East deposits, and subsequent shipment of samples to the ALS assay lab in Montreal, Que., Temas has started to use its proprietary regenerative chloride leach process for the extraction of vanadium from La Blache drill core material. The RCL testing using vanadium will take place over the course of the next 45 to 60 days, with results to follow.

Tim Fernback, Temas chief executive officer, commented: "The adoption of fusion-based reassaying has the potential to materially enhance our understanding of grade distribution at La Blache.

"By reprocessing up to 36,000 metres of historic core, we are accelerating our pathway toward feasibility without the time and cost of additional drilling.

"Applying our proprietary RCL technology to vanadium is the next step in demonstrating how our processing platform can uplock additional value from the same ore body."

Enhanced assay method unlocking additional metal value

Historical drilling at La Blache (including the November/December, 2025, drill program) has been assayed, showing significant and commercial quantities of vanadium, among other metals. Historically, the assays used were a three- or four-acid digestion assay, which yielded good results on the property. The company's metallurgical team has recommended a more complete digestion method, utilizing a fused bead to achieve near total dissolution, to provide a more complete analysis of the core to get a more accurate grade distribution.

Preliminary fusion-based assays have shown material improvements based on results from surface samples of the semi-massive oxide and massive oxide taken from surface exposures over parts of the Hervieux East and Hervieux West deposits within Temas's La Blache camp during summer of assessment work in 2025. The original assays were run using a four-acid digestion (ALS ME-MS61) followed by ICP analysis, and those same pulps were then rerun using the ME-MS81 fusion-based protocol of ALS. The systematic increases in critical metal content range from an average of 10 per cent to 60 per cent in these samples and reflect the total release of contained metals in the harder-to-dissolve (refractory) minerals.

While the initial comparison data set is limited, these results indicate that historical assays may have underreported total metal content.

As a result:

• 748 sample pulps from its 2022 diamond drill campaign have been submitted for fusion reassay;
• 36,614 m of historic drill core is being relogged, measured for specific gravity, and reassayed using the same protocol.

Those results will provide a robust assessment and be made available when received.

This strategy also materially reduces the company's development time by several years while significantly accelerating its path toward feasibility while preserving capital.

Now that these new assays are in the process of being finalized and completed at La Blache, the company will put this material into its proprietary metallurgical process to determine what can be taken out using RCL. Like the approximately 830-kilogram pilot testing that yielded 99.8 per cent pure TiO2 and Fe2O3 at La Blache, the company will be using RCL to determine the purity and content of the V2O5 at La Blache. This will be followed by additional RCL testwork completed on gallium, scandium and chromium later in the year.

Furthermore, the results of this assay and metallurgical work on vanadium will allow the company to restate its scoping study on La Blache resource with an additional 30 million tons of measured and indicated TiO2 resource, and include those valuable pay metals of gallium, scandium and chromium.

Vanadium testing scope and objectives

Temas has commenced RCL metallurgical testing on vanadium-bearing material from La Blache, and the study aims to demonstrate:

• Effective loading of vanadate species from the stored raffinate onto the proprietary resin at controlled pH and reduction oxidation/redox;
• Regenerable elution of vanadium into a concentrated strip solution suitable for ammonium metavanadate precipitation;
• Production of an AMV intermediate of acceptable purity (vanadium grade, low silicon, phosphorus, arsenic and iron) to support downstream V2O5 or electrolyte manufacture.

The testwork program is expected to be completed within 45 to 60 days, and results will follow soon after.

Successful extraction of commercial-grade vanadium products could support the inclusion of vanadium in a future update to La Blache scoping study.

Multimetal expansion strategy

Following completion of vanadium testwork, Temas plans to initiate RCL testing on gallium, scandium and chromium.

La Blache hosts mineralization containing these additional critical elements. Demonstrating commercial recoveries could enhance revenue diversification and strengthen project economics.

David Caldwell, chief operating officer of Temas, commented: "Looking specifically at vanadium to start, Temas will use RCL to determine the quantity and quality of V2O5 extracted at La Blache. Furthermore, our overall strategy is to demonstrate that multiple critical metals can be recovered efficiently from La Blache using RCL."

"Successful results from this RCL testwork will add to our intellectual property portfolio and will be the subject of future patent work by the company as well as enhancing project optionality, and aligns with our strategy of combining proprietary processing technology with resource ownership."

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; and
• Enhance the recovery of critical metals, battery metals, platinum group minerals, precious and base metals, and rare earth elements.

Auditor update

HLB Mann Judd has resigned as auditor of the company, and De Visser Gray LLP has been reappointed as auditor, effective as of today. The company initially appointed HLB Mann Judd in connection with its Australian Securities Exchange listing, given the firm's experience with entities dual-listed in Australia and Canada.

Following the appointment, the B.C. Securities Exchange advised the company that the appointment did not meet applicable Canadian reporting requirements. Accordingly, the company has reappointed De Visser Gray as its auditor to ensure compliance with Canadian and Australian regulatory requirements. The company would like to thank HLB Mann Judd for its services and professional support during its tenure.
