MONTREAL, June 3, 2026 /PRNewswire/ -- June 03, 2026 - Sydney, Australia - PMET RESOURCES INC. (THE "COMPANY" OR "PMET") (TSX: PMET) (ASX: PMT) (OTCQX: PMETF) (FSE: R9GA) is pleased to announce that it has received a non-binding Letter of Interest ("LOI") from Societe Generale ("SG"), a leading international corporate and investment bank, in relation to potential project financing for the Phase 1  development of the Company's 100%-owned Shaakichiuwaanaan Project, located in the Eeyou Istchee James Bay region of Quebec, Canada.

Under the LOI, SG has expressed interest in participating as a Mandated Lead Arranger for potential debt financing package. The LOI represents another important step in advancing PMET's long-term financing strategy and aligns with PMET's objective to assemble a high-quality syndicate of internationally recognized mining project finance lenders and Export Credit Agencies. This builds on the recently announced support and engagement from EDC, KfW IPEX-Bank and an additional major Canadian financial institution.

The LOI is intended to facilitate lender due diligence, including technical, environmental and commercial reviews, as PMET advances toward completion of its updated Feasibility Study targeted for calendar Q4 2026. 

Natacha Garoute, CFO, comments: "Societe Generale brings extensive global mining project finance expertise, including meaningful experience financing Quebec-based mining assets. Their interest further reinforces the quality, scale and strategic importance of the Shaakichiuwaanaan Project. We look forward to working closely with the SG team as we progress lender due diligence and continue building a robust financing syndicate to support the development of Phase 1."

The Company cautions that this letter is preliminary, non-binding, and conditional in nature. It does not constitute a credit approval, financing commitment, or definitive financing arrangement. Any future financing remains subject to satisfactory completion of comprehensive due diligence (including a site visit by SG), internal management and credit approvals, agreement on commercial terms, and final documentation. Financing discussions continue to progress in parallel with permitting, engineering optimization, product marketing and ongoing strategic commercial engagement.

About PMET Resources Inc.

PMET Resources Inc. is a pegmatite critical mineral exploration and development company focused on advancing its district-scale 100%-owned Shaakichiuwaanaan Property located in the Eeyou Istchee James Bay region of Quebec, Canada, which is accessible year-round by all-season road and proximal to regional hydro-power infrastructure.

In late 2025, the Company announced a positive lithium-only Feasibility Study on the CV5 Pegmatite for the Shaakichiuwaanaan Property and declared a maiden Mineral Reserve of 84.3 Mt at 1.26% Li₂O (Probable)¹. The study outlines the potential for a competitive and globally significant high-grade lithium project targeting up to ~800 ktpa spodumene concentrate using a simple Dense Media Separation ("DMS") only process flowsheet. Further, the results highlight Shaakichiuwaanaan as a potential North American critical mineral powerhouse with significant opportunity for tantalum and caesium in addition to lithium.

The Project hosts a Consolidated Mineral Resource² totalling 108.0 Mt at 1.40% Li₂O and 166 ppm Ta₂O₅ (Indicated) and 33.4 Mt at 1.33% Li₂O and 155 ppm Ta₂O₅ (Inferred) and ranks as a top ten lithium pegmatite globally in size. Additionally, the Project hosts the world's largest pollucite-hosted caesium pegmatite Mineral Resource at the Rigel and Vega zones with 0.69 Mt at 4.40% Cs₂O (Indicated), and 1.70 Mt at 2.40% Cs₂O (Inferred).
