PMET Announces Successful Phase 2 Caesium Testwork with Koch Technology Solutions

PMET Successfully Completes Phase 2 Caesium Testwork Program with Koch Technology Solutions

On September 22, 2026, PMET Resources Inc. announced a significant milestone in their ongoing partnership with Koch Technology Solutions (KTS), a subsidiary of Koch Industries. The successful completion of the Phase 2 bench-scale testwork program marks an essential step in the advancement of caesium processing techniques from pollucite concentrate sourced from PMET’s Shaakichiuwaanaan Project in Quebec, Canada.

The recent tests showcased a simplified and selective processing pathway for high-purity caesium chemical products, which is promising for the future of the industry. PMET’s ability to extract caesium using KTS's proprietary technology aims to reduce production costs while enhancing product quality. This development could streamline traditional caesium recovery processes, which often entail multiple purification stages.

Overview of the Testwork Program

The Phase 2 program was designed to evaluate KTS's unique flowsheet technology that allows for greater selectivity in caesium extraction. This innovative approach simplifies traditional methods, potentially leading to substantial cost reductions in the recovery of high-purity caesium products. KTS’s technology has been tested using pollucite concentrate produced through the company’s BerryPick Program, which aims to generate over 500 kilograms of concentrate for continued processing.

The testwork program revealed promising results, emphasizing KTS's capacity to produce multiple caesium products effectively. The results indicated a high selectivity for caesium with a significantly reduced impurity profile compared to conventional methods. PMET is now looking towards a follow-up testwork phase that will not only validate these findings but also result in initial marketable samples of caesium forms such as caesium carbonate and caesium formate.

Future Directions and Strategic Collaborations

PMET's leadership in the caesium market is expected to strengthen through further collaboration with strategic partners. The ongoing discussions to deepen relationships with KTS and other industry players underline a commitment to maximizing value from their caesium resources. This strategic focus is particularly pertinent as the market for caesium compounds continues to expand, driven by applications in various industries, from medical imaging to advanced solar technologies and precision GPS systems.

The integration of caesium extraction capabilities into PMET's operations is anticipated to enhance revenue potential significantly, as both caesium and tantalum are projected co-products at the Shaakichiuwaanaan site. Furthermore, a Preliminary Economic Assessment targeted for the fourth quarter of 2026 will shed light on the economic viability of these caesium credits and their impact on overall lithium production costs.

The Importance of Caesium

Caesium, particularly in the form of pollucite, is among the rarest minerals on the planet and is primarily found in LCT pegmatite systems. Its applications are critical, especially in industries like oil and gas drilling, medical technology, and emerging sectors such as solar energy. With the global market for caesium constrained, any enhancement in extraction and production methods can position PMET Resources as a pivotal player in providing this essential mineral to the worldwide market.

As PMET proceeds with additional testwork and continues to innovate within the caesium sector, it is poised to contribute significantly to the global supply chain while maximizing its remarkable mineral resources at the Shaakichiuwaanaan Project. The company’s next steps will further solidify its standing as a leader in critical mineral exploration and development.
