Temas's RCL Critical Minerals Patent Portfolio Expands into Vanadium
Patent filing follows recent RCL vanadium metallurgical testwork and further strengthens Temas' growing critical minerals technology platform
Highlights
Temas has initiated the filing of a new process patent covering the extraction of vanadium from complex ore bodies using its proprietary Regenerative Chloride Leach ("RCL") mixed chloride leaching technology.
Patent filing establishes a priority filing date of July 8, 2026, protecting the Company's latest metallurgical innovation.
Patent entitled "Chloride-based process for Vanadium extraction"
Filing follows the recent completion of the Company's previously announced RCL vanadium metallurgical testwork on material from its wholly-owned La Blache Titanium-Vanadium-Iron Project.
Represents another expansion of Temas' growing intellectual property portfolio supporting future technology licensing opportunities.
Follows Temas' 29 June 2026 results confirming extensive high-grade titanium-vanadium mineralisation at La Blache, including vanadium grades of up to 0.48% VâOâ over broad intervals, underpinning the vanadium endowment to which the newly patented RCL process can be applied.

VANCOUVER, BC / ACCESS Newswire / July 8, 2026 / Temas Resources Corp. ("Temas" or the "Company") (ASX:TIO)(CSE:TMAS)(OTCQB:TMASF)(FSE:26P0) is pleased to announce that, following the recent completion of the Company's Regenerative Chloride Leach ("RCL") vanadium metallurgical testwork announced earlier this year, the Company has initiated the filing of a new process patent covering the extraction of vanadium from complex ore bodies using mixed chloride leaching technology.
The patent application, entitled "Chloride-based process for Vanadium extraction" establishes a priority filing date of July 8, 2026, providing intellectual property protection for a novel process developed through the Company's ongoing metallurgical research and development activities.
The new patent application builds upon the encouraging results generated from Temas' proprietary RCL metallurgical testing on vanadium-bearing material from its 100%-owned La Blache Titanium-Vanadium-Iron Project in Québec, Canada. The work further demonstrates the adaptability of the RCL technology platform across multiple critical minerals while expanding the Company's growing portfolio of proprietary processing technologies.
As announced on 29 June 2026, Temas reported the first results from its systematic re-assay program at the Hervieux West deposit within La Blache, confirming extensive high-grade titanium-vanadium mineralisation together with gallium, scandium and chromium credits. Selected intervals returned vanadium grades of up to 0.48% VâOâ over substantial widths, including 143.0 m at 0.48% VâOâ (88.7% FeâOâ + TiOâ) in hole HWR-10-052. The vanadium extraction process now being patented is directly applicable to this style of Fe-Ti-V oxide mineralisation, reinforcing the potential for Temas to create value from both its own vanadium-bearing assets and comparable third-party ore bodies through the RCL platform.
The Company believes that securing intellectual property protection remains a critical component of its strategy to commercialize the RCL technology through future licensing agreements, strategic partnerships and deployment across global mineral projects. The Temas RCL technology platform is comprised of successfully granted US and Canadian metallurgical process patents for the extraction of Gold, Iron, Titanium, Nickel and Rare Earth Elements using its proprietary mixed-chloride leaching technology.
In addition to this new patent application for the extraction of Vanadium, the RCL platform is supported by eleven granted patents across multiple critical minerals and jurisdictions:
Gold - granted (United States)
Gold - granted (Canada)
Iron - granted (United States)
Iron - granted (Canada)

Vanadium - application filed, priority date 7 July 2026 (new)
Kyler Hardy, Executive Chairman, commented:
"One of our strategic objectives has always been to continually expand the RCL technology platform through the development of new process innovations. The successful application of RCL to vanadium extraction has resulted in a process that we believe is both novel and commercially valuable. Filing this patent represents another important milestone in strengthening Temas' intellectual property portfolio and reinforces the versatility of the RCL platform across multiple critical mineral applications."
Tim Fernback, President & Chief Executive Officer, commented:
"The filing of this patent is another important step in transforming Temas from a critical minerals developer into a global clean metallurgical technology company. Every new patent strengthens our competitive position and builds long-term value in our technology licensing business. As demand accelerates for secure supplies of critical minerals such as vanadium, we believe proprietary processing technologies like RCL will become increasingly valuable to miners seeking lower-cost, environmentally responsible extraction. We continue to evaluate further RCL applications across critical minerals, including gallium, scandium, chromium and rare earth elements and intend to keep expanding our intellectual property portfolio as future metallurgical programs are completed."
Expanding the RCL Intellectual Property Platform
The RCL technology platform continues to evolve beyond its original titanium applications into a broad hydrometallurgical process capable of recovering multiple critical minerals from complex ores, concentrates and mine waste.
The Company's intellectual property strategy is focused on protecting novel metallurgical processes that can be commercialized through:
Technology licensing;
Joint venture opportunities;
Strategic processing partnerships;
Proprietary processing of Temas' wholly-owned mineral assets.
The filing of "Chloride-based process for Vanadium extraction" represents another significant addition to Temas' expanding portfolio of proprietary RCL technologies.

Benefits 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.
