Star Metro - Temas Opens New RCL Metallurgical Lab to Accelerate Technology Deployment and Third-Party Revenue Opportunities

VANCOUVER, BC / ACCESS Newswire / March 31, 2026 / Temas Resources Corp. ("Temas" or the "Company") (ASX:TIO)(CSE:TMAS)(OTCQB:TMASF)(FSE:26P0) is pleased to announce the establishment of its Technology Research and Development Centre ("TRDC") metallurgical laboratory, within the laboratories of Insight R&D Inc., strategically located within the Greater Toronto-Hamilton corridor of Southern Ontario, Canada.

The TRDC will support a range of functions, including continued development of the Company's Regenerative Chloride Leach (RCL) technology, small-scale production of precious, critical and rare earth minerals, and advance RCL business development opportunities with third-party miners & explorers. It will also be used to evaluate the Company's critical mineral deposits at La Blache and Lac Brule, support training of the local technical workforce, and facilitate community engagement. In addition, the facility will undertake sample preparation for exploration, geotechnical and metallurgical testing, third-party material testwork and further process development activities.

"The establishment of the Temas' TDRC allows the company to immediately proceed to testwork and Intellectual Property ("IP") deployment, leveraging its IP, metallurgists, and Insight's established laboratories with both strong scale-up infrastructure and engineering talent that support our projected customer companies on five continents. The TDRC represents a great tool for exploration, business and process development, which we are putting to use immediately" said Temas COO David Caldwell. "It will not only help the team complete the ongoing RCL testwork at La Blache and Lac Brule, but it will be a key part of delivering RCL-based metallurgical testing to third parties seeking to use our novel mixed chloride approach to unlock enhanced metal recovery and operating cost savings with their deposits. To date, Temas has signed two third-party contracts to test RCL and has many more projects in our sales pipeline. The work done at the TDRC metallurgical lab facility will assist with future project feasibility studies, scale-up, and deployment of the RCL technology at full-scale."

Mr. Tim Fernback, Temas Chief Executive Officer commented:

"The establishment our TDRC metallurgical lab facility is the first step in what we envision not only as a future Temas centre for refinement of our novel RCL technology, but also a platform for development of new industry leading green metallurgical solutions. It allows us to not only complete both internal and third-party bench testing rock that is run of mine, concentrate or from mine tailings, but also allows us to conduct both mini-pilot and small-scale pilot testing in the future. Providing more of these additional services in-house will help speed along the development and deployment of our RCL technology."

RCL Platform Overview and Competitive Differentiation

Temas' RCL platform is an innovative, advanced hydrometallurgical platform designed for the efficient extraction of metals from complex mineralisation, 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 in fewer process steps than competing metallurgical approaches,

• Atmospheric pressure and lower-temperature operation relative to conventional chloride or sulphate routes, pressure oxidation or roasting, and other complex treatments for complex or refractory feedstocks,

• Closed-loop reagent recycling delivering materially lower operating costs, reduced environmental footprint, and

• Enhance the recovery of critical metals, battery metals, platinum group minerals, precious and base metals and rare earth elements by leveraging higher yields, lower operating costs and better margins.

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 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.
