Following a routine review by the Autorité des marchés financiers ("AMF"), the government agency responsible for regulating securities in the Province of Québec, Canada, the Company has filed an amended Technical Report (as defined below) correcting certain compliance-related irregularities.
HIGHLIGHTS
- The clarification, formatting and additional disclosure in the amended Technical Report have no impact on the economic or technical conclusions of the 2025 Lithium-only FS (as defined below) which remain as previously stated.
- The re-filing is not to be confused with the previously announced updated feasibility study inclusive of tantalum economics that is currently underway which the Company intends to release in Q4 of this year.
MONTREAL, Oct. 3, 2026 /PRNewswire/ — Oct. 3, 2026 – SYDNEY, Australia
PMET Resources Inc. (the "Company" or "PMET") (TSX: PMET) (ASX: PMT) (OTCQX: PMETF) (FSE: R9GA) announces that, following a routine review pursuant to the continuous disclosure review program by the AMF, it has filed on SEDAR+ an amended version, with an unchanged effective date of October 20, 2025, an issue date of November 14, 2025 and an amended date of October 2, 2026, of its previously filed technical report for the Shaakichiuwaanaan Project titled "CV5 Pegmatite Lithium-Only Feasibility Study NI 43-101 Technical Report – Shaakichiuwaanaan Project" (the "Technical Report"), prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects ("NI 43-101"). The amended Technical Report is a reissuance of the results originally announced in the October 20, 2025, news release by the Company announcing a positive lithium-only feasibility study ("FS") on the CV5 Pegmatite outlining the potential for a large-scale mining operation at the Shaakichiuwaanaan Project.
The amended Technical Report addresses comments requesting clarification, formatting and additional disclosure for compliance purposes in a small number of areas, including, qualified persons’ certificates content, improper scaling and map formatting, clarifications with respect to the reasonable prospects for eventual economic extraction for caesium, tantalum, and gallium, and clarifications with respect to the cut-off grade for caesium oxide.
The corrections causing the refiling do not, in any way, shape or form, affect the economic or technical conclusions of the FS. Furthermore, this amended Technical Report is not to be confused with the previously announced updated feasibility study inclusive of tantalum economics that the Company currently has underway and intends to release in Q4 of this year.
The amended version of the report is available on SEDAR+ and will be available shortly thereafter on the Company’s website. Readers are encouraged to read the amended Technical Report in its entirety, including all qualifications, assumptions, exclusions and risks that relate to the Mineral Resource, Mineral Reserve, and life of mine plan. The amended Technical Report is intended to be read as a whole, and sections should not be read or relied upon out of context.
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).
________________________
1 See Feasibility Study news release dated October 20, 2025. Probable Mineral Reserve cut-off grade is 0.40% Li2O (open-pit) and 0.70% Li2O (underground). Underground development and open-pit marginal tonnage containing material above 0.37% Li2O are also included in the statement. Effective Date of September 11, 2025.

2 Consolidated MRE (CV5 + CV13 pegmatites) is reported at an Li2O cut-off grade of 0.40% (open-pit), 0.60% (underground CV5), and 0.70% (underground CV13). A grade constraint of 0.50% Cs2O was used to model the Rigel and Vega caesium zones, contained entirely within CV13. The Effective Date is June 20, 2025. Mineral Resources are not Mineral Reserves as they do not have demonstrated economic viability. Mineral Resources are inclusive of Mineral Reserves.
