PMET Drills 27m at 1.14% Li2O and 3m at 5.82% Cs2O in 2025 Campaign

PMET Resources reports significant new lithium and caesium discoveries from its 2025 drilling campaign at the Shaakichiuwaanaan Property, reinforcing its position as a key North American critical minerals project.

  • Discovery of new lithium zones at CV4 and CV12 pegmatites
  • High-grade lithium intercepts exceeding 2.7% Li2O over substantial widths
  • New near-surface caesium zone identified at CV12 with strong grades
  • Extension of CV5 and CV13 pegmatite strike lengths to 5.0 km and 3.2 km respectively
  • 57,024 meters drilled in 2025 with results pending for 15,081 meters

Expanding the Lithium Frontier

PMET Resources Inc. has announced a series of compelling new discoveries from its 2025 drilling campaign at the Shaakichiuwaanaan Property in Quebec, Canada. The campaign, which encompassed over 57,000 meters of diamond drilling, has revealed multiple new lithium and caesium mineralized zones, notably at the CV4 and CV12 pegmatites. These findings come on the heels of a recently completed positive Feasibility Study on the CV5 Pegmatite, underscoring the project's growing stature in the critical minerals sector.

Noteworthy Lithium Intercepts

Among the highlights, drill hole CV25-1013 at the CV4 Pegmatite intersected 27 meters grading 1.14% lithium oxide (Li2O), including a higher-grade interval of 19.2 meters at 1.45% Li2O. Similarly, the CV12 Pegmatite delivered impressive results with intercepts such as 29 meters at 1.31% Li2O, including 12.5 meters at a remarkable 2.76% Li2O. These grades are comparable to the high-grade Vega and Nova zones elsewhere on the property, suggesting robust mineralization continuity and potential for resource expansion.

Emergence of Caesium Zones

In addition to lithium, PMET has identified a new near-surface caesium zone at CV12, with intercepts including 3 meters at 5.82% caesium oxide (Cs2O) within a broader 23-meter zone averaging 0.98% Cs2O. The caesium mineralization, hosted primarily in pollucite, extends over approximately 200 meters strike length and remains open for further delineation. This discovery complements previous high-grade caesium intercepts at CV5 and CV13, reinforcing the property's multi-commodity potential.

Extending Known Pegmatites

The drilling campaign also successfully extended the strike lengths of key pegmatites. The CV5 Pegmatite now stretches approximately 5.0 kilometers, while the CV13 Pegmatite extends to about 3.2 kilometers, both remaining open-ended. Step-out drilling at CV5 yielded 24.9 meters at 1.34% Li2O, including 11.2 meters at 2.16% Li2O, and a standout caesium intercept of 0.5 meters at 17.92% Cs2O, the highest grade recorded to date at that location.

Supporting Development and Future Plans

Beyond exploration, the 2025 program included condemnation and geomechanical drilling to support infrastructure development and mine planning. PMET is currently integrating the new data into updated geological models and preparing for a revised economic study slated for the second half of 2026. Pending assay results from 15,081 meters of drilling, including critical infill and step-out holes at CV13 and the Vega Zone, are expected to further refine the resource base and project economics.

Strategic Significance

Situated in the Eeyou Istchee James Bay region, the Shaakichiuwaanaan Property hosts one of the largest lithium pegmatite resources in the Americas and ranks among the top globally. The combination of lithium, tantalum, and caesium mineralization positions PMET Resources as a potential North American critical mineral powerhouse, with the recent discoveries enhancing the project's long-term value proposition.

Bottom Line?

PMET’s 2025 drilling advances Shaakichiuwaanaan’s critical minerals potential, setting the stage for updated resource models and development milestones in 2026.

Questions in the middle?

  • How will pending assay results from CV13 and the Vega Zone impact the overall resource estimate?
  • What are the implications of the new caesium zones for project economics and product diversification?
  • How will the updated economic study integrate these new discoveries and influence development timelines?
