Patriot Achieves Further Permitting Progress at the Shaakichiuwaanaan Lithium Project

Rhea-AI Summary

Patriot Battery Metals (OTCQX: PMETF) has reached a significant milestone in the permitting process for its Shaakichiuwaanaan Lithium Project in Quebec. The Impact Assessment Agency of Canada (IAAC) has completed the planning phase of the Federal environmental assessment process, publishing Tailored Impact Statement Guidelines and a detailed Permitting Plan.

The Federal process will run parallel with the ongoing Provincial environmental assessment, with the Provincial ESIA submission targeted for late 2025. The project is supported by three years of environmental baseline data and community consultations. The CV5 Spodumene Pegmatite, the project's main component, is accessible year-round and located 14 km from a major hydroelectric powerline.

Positive

• Project permitting remains on schedule with constructive engagement from authorities
• Three years of robust environmental baseline data already collected
• Strategic location with year-round access and proximity to hydroelectric power
• Federal and Provincial processes will run in parallel to streamline approval timeline

Negative

• Multiple regulatory approvals still required at Federal, Provincial, and Cree levels
• ESIA submissions not expected until late 2025

Federal permitting process progresses and aligns with the Provincial process already underway

MONTREAL, Sept. 3, 2025 /PRNewswire/ -  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 Federal 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 Plan were issued by IAAC for the Project. This important milestone indicates the formal commencement of the Federal impact assessment phase of the Project.

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 notes 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.

________________________________

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% 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, 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.
