About Patriot Battery Metals Inc.

Patriot Battery Metals Inc. is a hard -rock lithium exploration company focused on advancing its

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% Cs2O, 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

pegmatite resource in the Americas, and the 8th largest in the world.

A Preliminary Economic Assessment (“PEA”) was announced for the CV5 Pegmatite August 21,

2024, and highlights it as a potential North American lithium raw materials powerhouse. The PEA

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.

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

2The Consolidated MRE cut-off grade is variable depending on the mining method and pegmatite (0.40% Li2O open-

pit, 0.60% Li 2O underground CV5, and 0.70% Li 2O underground CV13). A grade constraint of 0.50% Cs 2O 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.
