PMET Resources to Expand Land Position in James Bay Region

November 12, 2025 – Montréal, QC, Canada November 12, 2025 – Sydney, Australia

PMET Resources Inc. (the “Company” or “PMET”) (TSX: PMET) (ASX: PMT)

(OTCQX: PMETF) (FSE: R9GA) is pleased to announce that it has entered into a definitive

agreement to expand its land position immediately west of the Shaakichiuwaanaan Property

through the acquisition of the Pikwa Property, located in the James Bay region of Quebec. Pursuant

to this agreement, t he Company will acquire a 100% interest in the P ikwa Property (the

“Acquisition”) from Azimut Exploration Inc. (“Azimut”) (TSXV: AZM) (OTCQX: AZMTF), a

mineral exploration company focused on Quebec, and SOQUEM Inc. (“SOQUEM”), a mineral

exploration subsidiary arm of Investissement Québec.

The Pikwa Property is comprised of 509 Exclusive Exploration Rights (a.k.a. mineral claims)

covering approximately 10 km of highly prospective greenstone belt trend extending immediately

west of the Company’s flagship Shaakichiuwaanaan Property. The Pikwa Property hosts a geological

setting with strong potential for multiple commodities over several different deposit styles

including orogenic gold (Au), porphyry (Au, Cu, Ag), and LCT pegmatite (Li, Cs, Ta, Ga, Rb).

With the acquisition, the Company consolidates its land position in the region and now controls

over 70 km of highl y prospective greenstone trend , extending continuously across its

Shaakichiuwaanaan, Pikwa, and Pontois properties (Figure 1). On the Shaakichiuwaanaan Property,

this greenstone belt hosts numerous Li-Cs-Ta (“LCT”) pegmatite occurrences including the world

class CV5 and CV13 deposits, highlighting the potential of the overall trend. Additionally, historical

exploration at the Pikwa Property has documented the presence of spodumene-bearing pegmatite,

along with the identification of spodumene grains in till, further enhancing the potential of the

Pikwa Property.

In addition to the strong LCT pegmatite potential, the Pikwa Property hosts multiple base and

precious metal targets – which ha ve been the focus of historical exploration – including the

Hyperion and Copperfield Prospects.

Darren L. Smith, Executive Vice President of Exploration for the Company, comments: “The

acquisition of the Pikwa Property is a strategic addition to our significant land holdings in the region and

consolidates some of the most prospective LCT pegmatite trend globally. The Pikwa Property includes over

10 km of greenstone belt, including its northern and southern margins, in addition to numerous base and

precious metal prospects where historical work has been focused. We look forward to integrating the Pikwa

Property into our 2026 exploration programs in the region.”

TERMS OF THE ACQUISITION

Pursuant to a property purchase agreement dated November 11, 2025, the Company has agreed

to acquire a 100% interest in the Pikwa Property from Azimut Exploration and SOQUEM for the

following consideration:

• an aggregate of 841,916 common shares in the capital of the Company at a deemed issue

price of $3.68 per share (“PMET Shares”) to be issued equally to each of Azimut and

SOQUEM upon closing of the acquisition (the “Closing”);

• a 1% net smelter return (“NSR”) royalty interest in the Pikwa Property granted to Azimut;

and

• a 1% NSR royalty interest in the Pikwa Property granted to SOQUEM.

The completion of the Acquisition is subject to customary closing conditions for a transaction of

this nature, including obtaining the approval of the Toronto Stock Exchange (the “TSX”), obtaining

all necessary consents and the absence of material adverse change occurring in respect of the

Pikwa Property.

The PMET Shares to be issued on Closing will be subject to a statutory hold period expiring four

months and one day following Closing, as well as additional contractual resale restrictions expiring

12 months after Closing with respect to 35% of the PMET Shares and expiring 24 months after

Closing with respect to the remaining 65% of the PMET Shares , with some exceptions for early

disposal where the price of PMET’s common shares reaches certain thresholds.

No finder’s fees or commissions were paid in connection with the Acquisition.

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 (the “Feasibility Study”) and declared a maiden

Mineral Reserve of 84.3 Mt at 1.26% Li 2O (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 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).

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 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 i nclusive of

Mineral Reserves.
