PMET Resources Announces Major Lithium and Caesium Discoveries

SYDNEY, Australia, December 15, 2025 – PMET Resources Inc. has made remarkable discoveries of lithium and caesium within its Shaakichiuwaanaan Property following extensive drilling in 2025. The results showcase promising new lithium zones, highlighting that PMET is firmly on track to position itself as a key player in the critical mineral space.

Recent Discoveries

Among the highlights from the 2025 drilling campaign is a new lithium zone unveiled in the CV4 Pegmatite. One notable drill hole reported an impressive 27.0 meters at 1.14% Li2O, with a prominent section grading 1.45% Li2O over 19.2 meters. Furthermore, drill hole CV25-875 at the CV12 Pegmatite indicated significant lithium values, presenting intercepts of 29.0 meters at 1.31% Li2O, including a remarkable 12.5 meters measuring 2.76% Li2O. This data illustrates the potential extension of the lithium-rich pegmatites, fueling excitement for future explorations.

The company has also reported encouraging findings of caesium in the CV12 Pegmatite. One drill hole exhibited 3.0 meters at a substantial 5.82% Cs2O within a broader anomalous zone extending 23.0 meters at 0.98% Cs2O, suggesting that the company may open new avenues in the lucrative caesium market.

Expanding Boundaries

Encouragingly, the drilling results have extended the strike lengths of the CV5 and CV13 pegmatites to approximately 5.0 km and 3.2 km, respectively. The continuous discovery of high-grade lithium and caesium reaffirm the project's potential and emphasize PMET’s growing confidence in the robust mineral system present at the Shaakichiuwaanaan Property. The findings also suggest a promising synergy between lithium and caesium resources, aligning with the growing demand in the green technology sector.

Drilling Campaign Insights

The comprehensive 2025 drilling campaign covered an expansive scope, successfully completing a total of 57,024 meters across 245 holes. Importantly, PMET managed to achieve its drilling objectives ahead of schedule and under budget, a testament to the efficiency of its team. Given the promising results, the ongoing exploration efforts are expected to further enhance PMET’s resource estimation process, potentially supporting a future re-assessment of the project's economics.

Darren L. Smith, PMET’s Executive Vice President of Exploration, highlighted the campaign's successful exploration of new targets and infill drilling, ensuring significant progress toward understanding the project’s mineral potential. Mr. Smith stated, “The 2025 drill campaign at Shaakichiuwaan was expansive in scope and completed among a backdrop of two Mineral Resource Estimate updates and a maiden Feasibility Study for lithium.”

Future Outlook

As PMET continue its efforts within the Shaakichiuwaan Property, it is anticipated that further drilling, including step-out and infill drilling, will continue to provide critical data that will enhance its already significant lithium and caesium resources. With a clear focus on developing its exploration targets and gathering conclusive evidence of the project’s capacity, PMET Resources is poised to cement its role within the North American critical minerals exploration landscape.

In addition, ongoing assessments will pave the way for informed decisions regarding future production timelines and strategic operational plans aligned with market demands. PMET Resources is dedicated to leveraging its extensive geological and mineralogical data for optimal resource development.

With lithium and caesium both projected to play essential roles in renewable energy technologies, PMET's continual advancements and discoveries could not only bolster its market position but significantly contribute to the global transition towards sustainable solutions. Stay tuned as PMET Resources propels forward on this innovative journey, unlocking the potential hidden within the depths of the Shaakichiuwaan Property.
