PATRIOT BATTERY METALS ANNOUNCES PROPOSED NAME CHANGE TO PMET RESOURCES

Patriot Battery Metals Inc. has decided to change its name to PMET Resources Inc. in English and Ressources PMET Inc. in French.

The company will retain its existing trading symbols: PMET on the Toronto Stock Exchange; and PMT on the Australian Securities Exchange.

The name change and corporate rebranding marks the next evolution of the company as development of the world-class Shaakichiuwaanaan project in Canada continues to advance, with the imminent completion of the feasibility study and continued strong progress with permitting and stakeholder engagement.

The evolution of the company's brand to PMET Resources is consistent with its growth as a diversified global critical minerals company, focused on becoming a reliable long-term supplier of critical minerals to key North American and European markets.

In line with this shift, the company's tagline will evolve from "North America's lithium powerhouse" to "North America's critical-mineral powerhouse," reflecting the broader geological endowment of Shaakichiuwaanaan. In addition to lithium, the project hosts tantalum, caesium and gallium resources, with the potential to deliver world-class supplies of each of these highly strategic minerals.

The company's president, chief executive officer and managing director Ken Brinsden said:

"The evolution of Patriot into PMET comes at the right time for our company and the Shaakichiuwaanaan project. Our new logo, a three-faced crystal, is representative of a mineral, with the three faces each representing the LCT components of our pegmatites: lithium, caesium and tantalum. It also represents the three cultures active on site and in the company more broadly, namely -- the Cree, French and English -- collaborating to build Shaakichiuwaanaan into a key supplier of critical minerals to the North American and European markets.

"PMET Resources, with our new logo and, importantly, website at pmet.ca, provides a fresh, effective and seamless platform to communicate with all of our key stakeholders."

Effective at the start of trading on Sept. 18, 2025, subject to final approval by the TSX, the company will commence trading on the TSX under the new name, with the name change expected to be effected by the ASX on Sept. 19, 2025 (Sydney). The new Cusip number and ISIN assigned to the company's common shares are 73015G 10 4 and CA 73015G 10 4 6, respectively. There will be no consolidation of share capital and shareholders are not required to change their existing share certificates for new certificates bearing the new company name. Company shares held electronically will be booked electronically. The company's change of name does not impact the rights of the company's securityholders and no further action is required by existing securityholders with respect to this change. All outstanding securities will remain valid under the new name.

About Patriot Battery Metals Inc.

Patriot Battery Metals is a hard-rock lithium exploration company focused on advancing its district-scale 100-per-cent-owned Shaakichiuwaanaan property (formerly known as Corvette), located in the Eeyou Istchee James Bay region of Quebec, Canada, which is accessible year-round by all-season road and is proximal to regional power line infrastructure. The project hosts the world's largest (1) pollucite-hosted caesium pegmatite mineral resource (2) at the Rigel and Vega zones with 690,000 tonnes (t) at 4.40 per cent Cs2O indicated and 1.70 million t at 2.40 per cent Cs2O inferred. Additionally, the project hosts a consolidated mineral resource, which includes the Rigel and Vega caesium zones, totalling 108.0 million t at 1.40 per cent Li2O, 0.11 per cent Cs2O, 166 parts per million (ppm) Ta2O5 and 66 ppm gallium (Ga) indicated, and 33.4 million t at 1.33 per cent Li2O, 0.21 per cent Cs2O, 155 ppm Ta2O5 and 65 ppm Ga inferred, and ranks as the largest lithium pegmatite resource in the Americas and in the top 10 globally.

Qualified/competent person

The technical and scientific information in this news release that relates to the Shaakichiuwaanaan property is based on, and fairly represents, information compiled by Darren L. Smith, MSc, PGeo, who is a qualified person as defined by National Instrument 43-101, Standards of Disclosure for Mineral Projects, and member in good standing with the Ordre des Geologues du Quebec (geologist permit No. 01968), and with the Association of Professional Engineers and Geoscientists of Alberta (member No. 87868). Mr. Smith has reviewed and approved the technical information in this news release.

Mr. Smith is an executive and vice-president of exploration for Patriot Battery Metals and holds common shares and options in the company.

(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 per cent Li2O open pit, 0.60 per cent Li2O underground CV5 and 0.70 per cent Li2O underground CV13). A grade constraint of 0.50 per cent 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.

Mr. Smith has sufficient experience, which is relevant to the style of mineralization, type of deposit under consideration and to the activities being undertaken to qualify as a competent person as described by the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (the JORC code). Mr. Smith consents to the inclusion in this news release of the matters based on his information in the form and context in which it appears.

We seek Safe Harbor.
