Patriot Albemarle Mou Concluded

VANCOUVER, May 15, 2024 - May 15, 2024 - Sydney, Australia

Highlights

• Both parties have mutually agreed not to extend the MOU, enabling Patriot to explore a broader range of strategic partnerships within the downstream lithium sector.
• Patriot has and continues to attract significant attention across the industry, reinforcing its position as a pivotal supplier of high-quality raw materials for lithium-ion batteries outside of China.
• Patriot maintains a constructive ongoing relationship with Albemarle.

Patriot Battery Metals Inc. (the "Company" or "Patriot") (TSX: PMET) (ASX: PMT) (OTCQX: PMETF) (FSE: R9GA) announces today that the Memorandum of Understanding ("MOU") 9-month term with Albemarle has concluded and will not be extended. Patriot expects to fully engage with other downstream companies in the Lithium supply chain and as such all the rights granted to Albemarle have expired, including any levels of exclusivity in respect of future mine production and links to downstream chemical conversion facilities.

As the scale and quality of Patriot's Corvette Project has become increasingly evident, the Company has received significant interest from participants in the lithium industry, given the potential for Corvette to be a large and high-quality raw material supplier for the future of lithium-ion battery supply chains ex-China. Enabling the company to fully engage with other downstream companies has been determined to be in the best interests of shareholders.

Since signing the MOU Albemarle and Patriot have worked together on the many technical aspects of an integrated project, advancing the scope of mine concentrate production and opportunities for a downstream lithium hydroxide plant integrated with the Corvette project. Further, the funding provided by Albemarle's strategic investment enabled a robust work program including installation of critical capital works such as the camp, all-weather access road and the recently completed eleven rig winter drill program.

Ken Brinsden, President and CEO of Patriot, expressed his appreciation for the partnership: "Our collaboration with Albemarle has been extremely valuable. We are proud of the progress we've made and are excited by the intense market interest in the Corvette project. As we move forward, Patriot is eager to expand its operations and explore new partnerships that support the growing demand for lithium raw materials and chemicals in North America and Europe.

We also look forward to continuing our productive relationship with Albemarle in a flexible, non-exclusive format", Mr Brinsden added.

As a result of the MOU conclusion the Investor Rights Agreement ("IRA") between Patriot and Albemarle Corporation dated August 3, 2023 was terminated in accordance with its terms. Following the termination all of the rights granted to Albemarle, including exclusivity, have expired providing Patriot with the flexibility to engage with multiple potential partners and further its strategic goals.

Patriot remains committed to maximizing shareholder value by capitalizing on the strategic opportunities available within the evolving landscape of the global lithium market.

The CV Lithium Trend is an emerging spodumene pegmatite district discovered by the Company in 2017 and is interpreted to span more than 50 kilometres across the Corvette Property. The core area includes the approximate 4.6 km long CV5 Spodumene Pegmatite, which hosts a maiden mineral resource estimate of 109.2 Mt at 1.42% Li₂O inferred¹.

To date, eight (8) distinct clusters of lithium pegmatite have been discovered across the Corvette Property - CV4, CV5, CV8, CV9, CV10, CV12, CV13, and the recently discovered CV14. Given the proximity of some pegmatite outcrops to each other, as well as the shallow till cover in the area, it is probable that some of the outcrops may reflect a discontinuous surface exposure of a single, larger pegmatite "outcrop" subsurface.

The information in this news release that relates to exploration results for the Corvette Property is based on, and fairly represents, information compiled by Mr. Darren L. Smith, M.Sc., P.Geo., 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 Géologues du Québec (Geologist Permit number 01968), and with the Association of Professional Engineers and Geoscientists of Alberta (member number 87868). Mr. Smith has reviewed and approved the technical information in this news release.

Mr. Smith is Vice President of Exploration for Patriot Battery Metals Inc. and holds common shares and options in the Company.

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.

Patriot Battery Metals Inc. is a hard-rock lithium exploration company focused on advancing its district-scale 100% owned Corvette Property located in the Eeyou Istchee James Bay region of Quebec, Canada, and proximal to regional road and powerline infrastructure. The Corvette Property hosts the CV5 Spodumene Pegmatite with a maiden mineral resource estimate of 109.2 Mt at 1.42% Li₂O inferred¹ and ranks as the largest lithium pegmatite resource in the Americas based on contained lithium carbonate equivalent (LCE), and one of the top 10 largest lithium pegmatite resources in the world. Additionally, the Corvette Property hosts multiple other spodumene pegmatite clusters that remain to be drill tested, as well as more than 20 km of prospective trend that remains to be assessed.
