Temas Provides Update on RCL Metallurgical Lab Commissioning and Initiates La Blache Bulk Sample Transfer

Executive Summary

• Temas Resources is on schedule to fully commission its Technology Research and Development Centre (TRDC) metallurgical laboratory in Ontario by July 2026.
• Over 13 metric tonnes of previously assayed drill core from the Hervieux-East and Hervieux-West deposits at the La Blache Titanium-Vanadium-Iron Project is being transferred to the TRDC for advanced metallurgical testing.
• The testing program aims to optimize the company's proprietary Regenerative Chloride Leach (RCL) technology, generating critical engineering data to support process commercialization, licensing opportunities, and future project development.

Key Details

• Laboratory Commissioning: TRDC commissioning activities are progressing as planned, with full operational status targeted for July 2026.
• Bulk Sample Transfer: >13 metric tonnes of previously assayed mineralized rock from the La Blache project (Québec) is being moved to the TRDC for initial operating program testwork.
• Source Material: Material originates from the Hervieux-East and Hervieux-West deposits, representing well-characterized mineralized material from historical drilling programs.
• Testing Objectives: Refine and optimize the proprietary RCL process under controlled laboratory conditions to generate additional data for future commercial applications and engineering development.
• Facility Role: The TRDC will serve as the primary center for continued RCL technology development, supporting internal metallurgical programs, third-party testing, process optimization, licensing opportunities, and future pilot-scale initiatives.
• Historical Pilot Validation: A prior ~1-ton pilot test yielded 88 kgs of 99.8% pure TiO2 commercial grade product.
• Cost & Efficiency Metrics: RCL technology has demonstrated validated operating cost reductions of >65% compared to conventional processing, with >69% lower operating costs attributed to closed-loop reagent recycling and near-ambient temperature processing.
• Technology Characteristics: RCL is a closed-loop hydrometallurgical process utilizing atmospheric pressure and lower temperatures to enhance recovery of titanium, vanadium, rare earth elements, and other critical minerals from complex ores, concentrates, slags, and tailings.

Notable Quotes

• Kyler Hardy, Executive Chairman: "The commissioning of our TRDC laboratory represents a significant milestone in the commercialization of the RCL technology platform. Having these capabilities in-house provides greater flexibility, faster turnaround times and strengthens our ability to support both our internal projects and third-party commercial opportunities."
• Tim Fernback, President & CEO: "The movement of over 13 metric tonnes of previously assayed La Blache material to the laboratory marks the beginning of an important phase of technical development for both our flagship project and our proprietary RCL technology... this work will further strengthen our commercialization strategy while advancing the development of La Blache as a potential long-term source of critical minerals."
