PMET Resources Inc. (the “Company” or “PMET ”) (TSX: PMET) (ASX: PMT)
(OTCQX: PMETF) (FSE: R9GA) is pleased to announce it has filed on SEDAR+ a technical
report (the “Technical Report”), prepared in accordance with National Instrument 43- 101 –
Standards of Disclosure for Mineral Projects (“NI 43- 101”). The Technical Report is titled “CV5
Pegmatite Lithium-Only Feasibility Study NI 43-101 Technical Report – Shaakichiuwaanaan Project”, with
an Issue Date of November 14, 2025, and Effective Date of October 20 , 2025. The filing follows
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 Technical Report has been prepared by G Mining Services Inc., with contributions from
Primero Group Americas Inc., AtkinsRéalis Group Inc., BBA Inc., Paterson & Cooke Canada Inc. ,
Vision Geochemistry Ltd., Alius Mine Consulting, WSP Global Inc., Mailloux Hydrog éologie and
GCM Expert, each consulting groups independent of the Company, in accordance with NI 43-101.
The report is available on SEDAR+ and will be available shortly thereafter on the Company’s
website. Readers are encouraged to read the FS Technical Report in its entirety, including all

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 (the “Feasibility Study”) 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 Shaakichiuwaanan
1 See Feasibility news release dated October 20, 2025. Probable Mineral Reserve c ut-off grade is 0.40% Li2O (open-pit) and 0.70% Li 2O
(underground). Underground development and open -pit marginal tonnage containing material above 0.37% Li 2O are also included in the
statement. Effective Date of September 11, 2025.

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% Li 2O and 155 ppm Ta 2O5 (Inferred), and ranks as the
largest3 lithium pegmatite resource in the Americas, and in the top ten globally. Additionally, t he
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).

2 The Consolidated MRE (CV5 + CV13 pegmatites), which includes the Rigel and Vega caesium zones, totals 108.0 Mt at 1.40% Li2O, 0.11%
Cs2O, 166 ppm Ta2O5, and 66 ppm Ga, Indicated, and 33.4 Mt at 1.33% Li 2O, 0.21% Cs2O, 155 ppm Ta2O5, and 65 ppm Ga, Inferred,
and is reported at a cut-off grade of 0.40% Li2O (open-pit), 0.60% Li2O (underground CV5), and 0.70% Li2O (underground CV13). A grade
constraint of 0.50% Cs2O was used to model the Rigel and Vega caesium zones. The Effective Date is June 20, 2025 (through drill hole CV24-
787). Mineral Resources are not Mineral Reserves as they do not have demonstrated economic viability. Mineral Resources are inclusive of
Mineral Reserves.
