PMET Resources Achieves Success in Tantalite Concentrate Production from CV5 Deposit

Introduction

On September 25, 2025, PMET Resources Inc. announced a significant advancement in resource recovery efforts at its 100%-owned Shaakichiuwaanaan Project located in Quebec, Canada. The company successfully produced a marketable tantalite concentrate from its CV5 Deposit, a crucial step in tapping into valuable mineral resources.

Overview of Tantalite Production

The company's journey began with bench-scale testwork resulting from various processing techniques applied to DMS (Dense Media Separation) waste streams from the CV5 Pegmatite. The tests achieved favorable outcomes, yielding tantalite concentrates with pleasing grade and recovery rates. Specifically, tests on two master drill core composites (MC001 and MC002) revealed impressive recoveries of 45% and 49%, respectively, with tantalum oxide (Ta2O5) grades of 8.7% and 6.6%.

Advantages of Methodology

The processing methods used by PMET are standard in the industry and involve low-cost mineral processing technologies. These established techniques have previously been successful in recovering tantalum from DMS waste streams at lithium pegmatite operations globally. The company believes that the same methods can be effectively applied at the Shaakichiuwaanaan Project, allowing for tantalum recovery without compromising lithium extraction.

Tantalum: A Critical Resource

Tantalum is a strategic metal utilized in many high-tech applications, including electronics and aerospace technologies. It has been recognized as a critical mineral in various jurisdictions, including Canada, the EU, and the USA. The global market for tantalum continues to expand, driven by innovations in technology and increasing demand in emerging sectors, such as semiconductors, medical devices, and defense equipment.

Implications for the Shaakichiuwaanaan Project

The successful production of tantalite concentrate underlines the project's potential to generate additional revenue streams alongside lithium. The Shaakichiuwaanaan Project is recognized as one of the largest tantalum pegmatite resources worldwide, making it an attractive opportunity for future exploration and development. PMET's management, led by Executive Vice President Darren L. Smith, emphasizes that this achievement not only signifies successful testing but also aligns with the company's commitment to maximizing economic returns from its assets.

Next Steps and Future Plans

Following these promising results, PMET has planned further testwork aimed at refining the tantalite recovery circuit design. This initiative is set to enhance the project’s viability and is part of the ongoing feasibility study on the broader lithium operations at CV5, targeted for completion in the upcoming months. This study is crucial as it will inform further steps related to mine authorization and production ramp-up.

Conclusion

The production of marketable tantalite concentrates from the CV5 deposit represents a pivotal moment for PMET Resources and the Shaakichiuwaanaan Project. By harnessing the economic potential of tantalum alongside lithium, PMET is well-positioned to contribute positively to the critical minerals supply chain while enhancing its profitability.
