Temas Resources Corp Initiates Filing of New Process Patent Covering Extraction of Chromium Using Regenerative Chloride Leach Technology
Temas Resources Corp. had initiated the filing of a new process patent covering the extraction of chromium from complex ore bodies using its proprietary Regenerative Chloride Leach (RCL) mixed chloride leaching technology. The patent application, entitled 'Chloride-based process for Chromium extraction,' establishes a priority filing date of July 10, 2026, further expanding Temas’ growing RCL intellectual property portfolio. Chromium is a critical material essential to the stainless steel, aerospace, defence, energy infrastructure and advanced manufacturing, with a global market valued at approximately USD 23,900 million in 2024. The filing follows the recent completion of the Company's previously announced RCL vanadium metallurgical patent filing demonstrating the ability of the RCL Platform Technology to be adapted across multiple critical minerals, as well as its strong applicability to Temas’ 100% owned La Blache Project, which hosts high grade of vanadium over broad intervals. The chromium extraction process has the potential application to Temas’ wholly owned La Blache and Lac Brule titanium-vanadium-iron projects, as well as third-party chromium bearing deposits, concentrates and mine waste. The patent application, entitled 'Chloride-based process for Chromium extraction' establishes a priority filing date of July 10, 2026, providing intellectual property protection for a novel process developed through the Company's ongoing metallurgical research and development activities. Approximately 85-90% of chromium production is consumed in the manufacturing of stainless steel, while high-purity chromium metal is increasingly required for aerospace superalloys, military armour systems, turbine components, hydrogen technologies and emerging battery applications. According to Grand View Research, the global chromium market was valued at USD 23,900 million in 2024 and is forecast to reach approximately USD 34,500 million by 2030, reflecting continued demand growth by infrastructure investment, electrification, and defence manufacturing. The new patent application builds upon the encouraging results generated from Temas' proprietary RCL metallurgical testing on 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. 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 applications for the extraction of Chromium and the recently announced patent filing for Vanadium extraction, which is directly applicable to the Company’s La Blache Project in Québec, Canada. 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), Iron - granted (India), Titanium - granted (United States), Titanium - granted (Canada), Nickel - granted (United States), Nickel - granted (Canada), Rare Earth Elements - granted (India), Rare Earth Elements - granted (Canada), Vanadium - application filed, priority date 8 July 2026 (new), Chromium – application filed, priority date 10 July 2026 (new). 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 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. 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. A significant cost reduction of over 65% 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. 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. This means the reduced environmental footprint and enhanced ESG profile are benefits that extend to ores and minerals previously noted, not just TiO2. Just as we've demonstrated high-quality, 99.8% TiO2 product from pilot testing the RCL platform is engineered for high recovery and purity of all target metals. 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.
