Patriot Achieves Further Permitting Progress at the

Shaakichiuwaanaan Lithium Project

Federal permitting process progresses and aligns with the Provincial process already

underway

September 3rd, 2025 – Montreal, QC, Canada

September 4th, 2025 – Sydney, Australia

Highlights

• Permitting of the Shaakichiuwaanaan Project is on schedule and progressing well.

• The planning phase of the Federal environmental and social impact assessment process

is now formally complete , culminating in the Impact Assessment Agency of Canada

(IAAC) publishing its Tailored Impact Statement Guidelines and a detailed Permitting Plan

for the Shaakichiuwaanaan Lithium Project.

• The Permitting Plan is consistent with the Company’s previously estimated and

reported overall mine authorization timeline.

• This Federal process will run in parallel with the Provincial environmental and social impact

assessment process already underway, with submission of the Provincial Environmental and

Social Impact Assessment ( “ESIA”) targeted for late 2025, and the equivalent F ederal

application to be submitted shortly thereafter.

• The ESIA submissions will be supported by over three years of robust environmental base

line data studies and extensive community consultations.

Ken Brinsden , Patriot CEO and President , comments: “ Within the approvals process to-date ,

engagement with both the Cree, provincial and federal authorities has been constructive and timely. Further,

we are pleased to see that the Impact Assessment Agency of Canada is aiming to minimize duplication

and ensure full use is made of the work contributing to the Cree and provincial level assessment.

“It can’t be underestimated how much work has already been achieved by Patriot to ensure

Shaakichiuwaanaan is well -placed in the global lithium raw material development pipeline. Moving the

project from discovery and the establishment of a globally significant resource, to the upcoming mine

authorization process in less than 4 years is a remarkable achievement that demonstrates both the quality

of the Project and team delivering it.”

Patriot Battery Metals Inc. (the “Company” or “Patriot”) (TSX: PMET) (ASX: PMT)

(OTCQX: PMETF) (FSE: R9GA) is pleased to provide a progress update on the permitting

process of the Company’s wholly owned Shaakichiuwaanaan Property (the “Property” or

“Project”), located in the Eeyou Istchee James Bay region of Quebec. The CV5 Spodumene

Pegmatite, which forms the bulk of the MRE , is accessible year-round by all -season road and is

situated approximately 14 km from a major hydroelectric powerline corridor. The CV13 Pegmatite

(which is outside the scope of the Company’s CV5 ESIA) is located <3 km along geological trend

from the CV5 Pegmatite, which hosts additional lithium, caesium and tantalum resources (see news

release dated July 20, 2025).

Federal Project Approval Submissions and ESIA Studies

In February 2025, Patriot submitted its Initial Project Description for the Shaakichiuwaanaan

Lithium Project (CV5 Pegmatite) to IAAC, in order to formally initiate the Federal elements to the

Project permitting process.

In the period since the submission of the Initial Project Description , the Company has engaged

with the Federal Joint Assessment Committee (consisting of representatives of IAAC and the Cree

Nation Government) and the IAAC has undertaken its formal planning and public comment period.

In August 2025, the Tailored Impact Statement Guidelines , Permitting Plan, Cooperation Plan,

Indigenous Engagement and Participation Plan, and Public Participation Pl an were issued by IAAC

for the Project. This important milest one indicates the formal commencement of the Federal

impact assessment phase of the Project.

The public reference for progress in respect of the IAAC schedule can be found at the following

link: https://iaac-aeic.gc.ca/050/evaluations/proj/89271

The Federal impact assessment process will run in parallel with the Provincial permitting process

for the Project which commenced in 2023, and will leverage the existing provincial process to

streamline the federal requirements to the extent possible.

The Company also note s with interest the efforts of federal authorities to minimize duplication

with the provincial approval process. The Company intends to maintain close-contact with all the

key Government agencies and the Cree, to ensure a diligent and timely approval process for the

Project.

Overall Project Approval Summary Position

Over approximately a 3-year period, extensive environmental baseline data collection field

programs and community consultations have been completed as planned to underpin the

Company’s ESIA (supporting both Federal and Provincial processes) , for the development of the

CV5 Pegmatite.

As a result of the above, now combined with the constructive and timely approach of regulatory

authorities, the provincial ESIA submissions remain on-track for presentation in late 2025, with

the federal ESIA to follow shortly thereafter.

district-scale 100%-owned Shaakichiuwaanaan Property (formerly known as Corvette) located in

the Eeyou Istchee James Bay region of Quebec, Canada, which is acce ssible year-round by all -

season road and is proximal to regional powerline infrastructure. The Project hosts the world’s

largest1 pollucite-hosted caesium pegmatite Mineral Resource 2 at the Rigel and Vega zones with

0.69 Mt at 4.40% Cs2O, Indicated, and 1.70 Mt at 2.40% Cs 2O, Inferred. Additionally, the Project

hosts a Consolidated Mineral Resource, which includes the Rigel and Vega caesium zones, totalling

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% Li2O, 0.21% Cs2O, 155 ppm Ta2O5, and 65 ppm Ga, Inferred, and ranks as the largest lithium

1 Determination based on Mineral Resource data, sourced through July 11, 2025, from corporate disclosure.

2 The Consolidated MRE cut -off grade is variable depending on the mining method and pegmatite (0.40% Li 2O

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, which are entirely within the CV13 Pegmatite’s open -pit

mining shape. The Effective Date of the MREs is June 20, 2025 (through drill hole CV24-787). Mineral Resources

are not Mineral or Ore Reserves as they do not have demonstrated economic viability.

Although the Company believes its expectations are based upon reasonable assumptions and has
