PMET Resources Inc. (TSX: PMET) has disclosed final assay results from its 2025 diamond drill campaign at the Shaakichiuwaanaan Property in Quebec, revealing the highest lithium grades ever recorded at the Vega Zone and the emergence of a new high-grade lithium-tantalum zone dubbed “Helios” at the CV13 pegmatite. Caesium assays remain pending, with multiple holes triggering overlimit thresholds.
This update completes reporting for 245 holes drilled over 57,024 metres in 2025 across multiple pegmatite zones. With the Vega Zone returning multiple intercepts over 7% Li₂O and the Helios discovery suggesting further expansion potential at CV13, the results position PMET Resources Inc. for a significant resource model update and revised economic study in the second half of 2026.
How does the Vega Zone drilling reshape the resource narrative for PMET’s Shaakichiuwaanaan Property?
The Vega Zone has now firmly established itself as the high-grade core of PMET Resources Inc.’s multi-pegmatite Shaakichiuwaanaan Property. Three separate intercepts exceeding 7% lithium oxide were reported from Vega during the final leg of the 2025 campaign, including 0.7 metres at 7.71% Li₂O in CV25-1016 and 1.1 metres at 7.32% Li₂O in CV25-1023.
Even more significant is the consistent grade over longer widths. CV25-1017A returned 24.7 metres at 4.00% Li₂O including a 7.0 metre interval at 6.04% Li₂O, marking the widest high-grade intercept above 6% from any PMET zone, including the previously leading Nova Zone. Other holes returned 49.7 metres at 2.08% Li₂O and 20.6 metres at 3.31% Li₂O.
This level of spodumene concentration is not only unusual but commercially significant in the context of global lithium exploration. The strength of these intercepts could materially shift the weighting of future mine planning toward underground exploitation strategies at CV13, potentially expanding PMET’s reserve base beyond its current focus on CV5.
What does the Helios discovery at CV13 mean for exploration upside and zone continuity?
The Helios Zone, encountered near-surface within the CV13 pegmatite, marks a new high-grade system adjacent to the Rigel and Vega zones. Initial intercepts include 8.8 metres at 2.97% Li₂O (including 5.4 metres at 4.60% Li₂O) and 6.4 metres at 2.61% Li₂O, with Helios also showing coincident tantalum grades and strong caesium mineralisation based on overlimit triggers.
The near-surface nature of the Helios discovery enhances development optionality, offering potential early feedstock during any future underground mining ramp-up. Strategically, it opens the door to continued lateral expansion of the CV13 footprint and may reframe PMET’s block modeling assumptions ahead of its 2026 study revision.
Importantly, Helios exhibits similar multi-commodity enrichment patterns to Vega and Rigel, reinforcing the polymetallic character of the Shaakichiuwaanaan system. Caesium results are pending but may further elevate Helios’s strategic relevance if grades approach economic thresholds.
How does the CV4 pegmatite’s maiden drilling inform the eastern extension potential of CV5?
The CV4 pegmatite, situated 1.5 kilometres east of CV5, returned several moderate-grade lithium intercepts in its maiden drilling campaign. These include 15.0 metres at 1.07% Li₂O, 12.0 metres at 1.42% Li₂O, and 7.0 metres at 2.00% Li₂O. While these do not match the ultra-high grades of Vega, the spatial trend is what matters.
PMET Resources Inc. interprets the CV4 results as supporting a 1.5 kilometre eastern strike extension of the CV5 system. This is potentially significant because the CV5 pegmatite already underpins the company’s 84.3 million tonne Probable Reserve base at 1.26% Li₂O. If CV4 can be delineated as a mineralized continuation, it may extend PMET’s underground development model, unlocking more marginal tonnage while optimizing infrastructure reuse.
How do the CV8 and Rigel results affect the broader exploration thesis at Shaakichiuwaanaan?
While CV13 remains the headline story, the Rigel and CV8 pegmatites quietly reinforce the multi-zone continuity at the project. Rigel infill drilling returned 11.5 metres at 2.87% Li₂O, including 6.9 metres at 4.40% Li₂O. Tantalum mineralisation also remained robust, with 1,974 ppm Ta₂O₅ intersected over 7.9 metres in CV25-913.
At CV8, the best intercepts came from CV25-940A, yielding 3.1 metres at 1.52% Li₂O and 3.5 metres at 1.26% Li₂O, with notable tantalum enrichment above 300 ppm Ta₂O₅. While not headline grades, the zone’s intercept widths (up to 20.4 metres) and spodumene presence support the thesis of volume potential in a structurally favorable setting.
CV8’s location near ultramafic rocks—a pattern commonly associated with PMET’s largest spodumene pegmatites—warrants further investigation. The company has flagged this area for follow-up drilling due to the strong alignment between geochemistry, mineralogy, and structural context.
What are the next steps for PMET and how could they influence the 2026 economic revision?
With lithium and tantalum assay reporting now complete for all 2025 holes, PMET Resources Inc. is entering the data integration phase. The company’s geology team is actively modeling host rock and pegmatite geometry across CV5 and CV13 in preparation for a revised economic study slated for H2 2026.
Key near-term activities include incorporating the Helios discovery into the broader CV13 model, integrating caesium data once overlimit assays are received, and advancing permitting for an underground bulk sample at CV5. The study will likely revisit cut-off grade assumptions, metallurgical recovery models, and capital cost parameters—especially given the high-grade upside and zone complexity now emerging at Vega and Helios.
Should the caesium results at CV13 validate Helios as a commercial Cs-Ta-Li zone, PMET could position itself as one of the few developers with economically relevant exposure to all three elements critical to high-performance energy storage and electronics.
What is the current market sentiment on PMET Resources Inc. following the final drill campaign disclosure?
As of January 22, 2026, PMET Resources Inc. shares trade across four exchanges including the TSX (PMET), ASX (PMT), OTCQX (PMETF), and Frankfurt Stock Exchange (R9GA). The stock had previously gained momentum after the October 2025 Feasibility Study and has seen renewed interest following December’s partial drill results. However, the full impact of the Vega and Helios disclosures will likely depend on the forthcoming caesium assay data and how the market interprets PMET’s 2026 study revision scope.
Analyst coverage remains cautious but constructive. The presence of multiple ultra-high-grade lithium intercepts within a single pegmatite zone is rare, and if sustained across strike and depth, could justify a re-rating of PMET’s resource quality. Conversely, delays in caesium data or permitting for the bulk sample may temper near-term enthusiasm.
