TEMAS' RCL CRITICAL MINERALS PATENT PORTFOLIO EXPANDS INTO CHROMIUM

Following the recent completion of Temas Resources Corp.'s regenerative chloride leach (RCL) metallurgical test work announced earlier this year, the company has initiated the filing of a new process patent covering the extraction of chromium from complex orebodies using mixed chloride leaching technology.

Highlights:

• Temas has initiated the filing of a new process patent covering the extraction of chromium from complex orebodies using its proprietary regenerative chloride leach (RCL) mixed chloride leaching technology;
• Patent application, entitled "Chloride-based process for Chromium extraction," establishes a priority filing date of July 10, 2026, further expanding Temas's 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 $23.9-billion (U.S.) in 2024;
• 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's 100-per-cent-owned La Blache project, which hosts high grade of vanadium over broad intervals;
• The chromium extraction process has the potential application to Temas's wholly owned La Blache and Lac Brule titanium-vanadium-iron projects, as well as third party chromium-bearing deposits, concentrates and mine waste;
• Expands the commercial opportunity for the RCL platform through future technology licensing, strategic processing partnerships and deployment across global mining operations;
• Builds on Temas's portfolio of 11 granted metallurgical process patents and reinforces the company's strategy of becoming a leading provider of environmentally responsible critical minerals processing technology;
• The company continues to advance confidential discussions and third party metallurgical testing with potential commercial partners regarding deployment of the RCL platform across multiple critical minerals;

Why this matters to investors -- every new RCL application expands the company's commercial opportunity:

1. Expands the value of the RCL technology platform: Each new patent broadens the commercial reach of Temas's proprietary RCL process beyond titanium and vanadium into another strategically important critical mineral, increasing the potential for future licensing, processing partnerships and additional revenue opportunities.
2. Adds to Temas's growing portfolio of high-value intellectual property: With 11 granted patents and new patent applications for both vanadium and chromium, Temas continues to strengthen the competitive moat around its metallurgical technology, creating long-term strategic value that extends well beyond its mineral assets.
3. Positions Temas to benefit from increasing demand for secure Western critical mineral supply chains: Chromium is essential to stainless steel, aerospace, defence, energy infrastructure and advanced manufacturing. By developing environmentally responsible extraction technology applicable to both its own projects and third party deposits, Temas is building a scalable technology business aligned with growing global demand for critical minerals.

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 continuing metallurgical research and development activities.

Chromium is classified as a critical mineral in numerous Western countries due to its importance in defence, aerospace, energy infrastructure and advanced manufacturing. Approximately 85 per cent to 90 per cent 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 $23.9-billion (U.S.) in 2024 and is forecast to reach approximately $34.5-billion (U.S.) by 2030 (source: Grand View Research, Chromium Market Size, Share & Trends Report, 2025), reflecting continued demand growth by infrastructure investment, electrification and defence manufacturing.

Tim Fernback, president and 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. This growing global market for chromium metal further highlights the commercial significance of developing proprietary environmentally responsible chromium extraction technologies such as the Temas RCL platform. As demand accelerates for secure supplies of critical minerals such as chromium, we believe proprietary processing technologies like RCL will become increasingly valuable to miners seeking lower-cost, environmentally responsible extraction."

The new patent application builds upon the encouraging results generated from Temas's proprietary RCL metallurgical testing on its 100-per-cent-owned La Blache titanium-vanadium-iron project in Quebec, 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 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 comprises successfully granted U.S. 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 Quebec, Canada. The RCL platform is supported by 11 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 July 8, 2026 (new);
• Chromium -- application filed, priority date July 10, 2026 (new).

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's wholly owned mineral assets.

The filing of "Chloride-based process for Chromium extraction" represents another significant addition to Temas's expanding portfolio of proprietary RCL technologies.

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 one tonne of material from its La Blache TiO2 (titanium dioxide) mineral property yielding 88 kilograms of a 99.8-per-cent-pure-TiO2 commercial-grade product.

Validated cost reduction: A significant cost reduction of over 65 per cent is validated for TiO2 processing using the RCL platform technology (for example, reagent recycling, potentially lower energy use and optimized recovery). 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. Operating costs were over 69 per cent lower compared with conventional processing due to its core features operating at near ambient temperatures. This means the reduced environmental footprint and enhanced ESG (environmental, social and governance) profile are benefits that extend to ores and minerals previously noted, not just TiO2.

High recovery potential: Just as the company has demonstrated high-quality, 99.8-per-cent-TiO2 product from pilot testing, the RCL platform is engineered for high recovery and purity of all target metals. The company's 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 around the world, enhancing both extraction and recovery for the operator.
