New High-grade Lithium, Caesium, and Tantalum Pegmatite Discoveries in Surface Exploration Works

PMET Resources Extends Mickel Trend to 10.5km as Surface Discoveries Fuel 45,000m Drill Campaign Ahead of Q4 Feasibility Update

Executive Summary

PMET Resources announced multiple new high-grade lithium, caesium, and tantalum pegmatite discoveries across its Quebec portfolio based on 2025 surface exploration programs.
Key discoveries include the Cosma caesium pegmatite (up to 16.43% Cs2O), Felix and Drakkar spodumene pegmatites (up to 2.45% Li2O), Skald (2.94% Li2O), and Overload (7.53% Cs2O, 3,768 ppm Ta2O5).
These findings extend the prospective Mickel LCT pegmatite trend to approximately 10.5 km and demonstrate significant exploration potential across the company's >70 km La Grande Greenstone Belt tenure.
The discoveries complement existing CV5 and CV13 resources, which already host a consolidated mineral resource of 108.0 Mt Indicated at 1.40% Li2O and 166 ppm Ta2O5, plus a world-class pollucite-caesium resource at CV13.
Follow-up surface work is planned for 2026 at Shaakichiuwaanaan, Pikwa, and Eastmain, with options being evaluated for next-stage exploration at Pontax.
This announcement follows a steady progression of technical milestones: initial caesium discovery (Jul 2025), definitive feasibility study (Oct 2025), $138M equity raise (Feb 2026), ESIA submission (Apr 2026), and the commencement of a 45,000m summer-fall drill campaign (May 2026).

Material Impact

The June 2, 2026 surface exploration update is a routine positive development that aligns with previously announced exploration objectives and the active 2026 drill campaign.
Surface grab and channel sampling results are preliminary and do not yet constitute drill-verified resources. While the grades are compelling, historical precedent in pegmatite systems shows significant variability between surface outcrop assays and downhole intercepts.
The news does not immediately alter the financial metrics from the October 2025 feasibility study (NPV $1.19B, IRR 18%), as the updated Q4 2026 study will be required to integrate these new trends into the economic model.
Market expectations were already priced in following the May 21 drill campaign announcement. The incremental discovery potential adds optionality and de-risks the long-term resource base, but lacks the immediate catalyst required to trigger a material re-rating.
Risk-averse perspective: Surface discoveries must be followed by systematic diamond drilling to confirm continuity, grade consistency, and metallurgical recoverability before they can be considered value-accretive.

Company Overview

PMET Resources Inc. (formerly Patriot Battery Metals) is a Canadian critical minerals company focused on the development of the Shaakichiuwaanaan Project in the Eeyou Istchee James Bay region of Quebec.
Flagship asset: CV5 pegmatite, hosting a maiden Probable Mineral Reserve of 84.3 Mt at 1.26% Li2O.
The project is transitioning from a lithium-focused operation to a multi-commodity powerhouse, integrating high-grade caesium (CV13 pollucite) and tantalum as co-products.
The October 2025 feasibility study outlined a production target of up to 800,000 tpa of SC5.5 spodumene concentrate over a ~19-year mine life, with an after-tax NPV8% of ~US$1.19 billion and an IRR of ~18%.
The company has consolidated over 70 km of contiguous greenstone belt tenure across Shaakichiuwaanaan, Pikwa, Pontois, and Pontax properties, positioning it as one of the largest LCT pegmatite trends in the Americas.
