GLOBAL BATTERY METALS TO INCREASE LEINSTER LITHIUM PROJECT EQUITY INTERESTS TO 55% WITH SECOND PROPERTY OPTION EXERCISE

Global Battery Metals Ltd. has elected to exercise its second option (second option earn-in) with respect to the Leinster lithium property, in accordance with the terms of an amended and restated letter of intent dated Aug. 15, 2022, between the company and LRH Resources Ltd. (LRHR), an arm's-length private exploration company and wholly owned subsidiary of Technology Minerals PLC.

With the second option earn-in exercise, Global Battery Metals will acquire an additional 37.5-per-cent equity interest, bringing the company's total equity interest in the project to 55 per cent. Having now spent the required 500,000 euros on property exploration and development, the company will pay Technology Minerals PLC, the parent company and owner of LRHR, 5,000 euros in cash and issue 385,000 common shares at a deemed price of 17 cents per share, on or about July 27, 2023. The issuance of the common shares remains subject to the approval of the TSX Venture Exchange. Project fulfilment requirements were previously announced in the company's Aug. 19, 2022, news release.

The project, located south of Dublin in the counties of Wicklow and South Carlow in the Republic of Ireland, is a promising lithium pegmatite project consisting of 16 prospecting licence areas situated adjacent to the joint Ganfeng Lithium/International Lithium Corp. Blackstairs lithium project, and covering approximately 525 square kilometres along and adjacent to the East Carlow deformation zone (ECDZ), which is recognized as a major controlling structure to pegmatite emplacement.

The project's drill program, currently under way at the Knockeen prospect, is permitted for up to 10 drill holes and has recorded multiple pegmatite intercepts in the first holes, which are currently being processed and analyzed. Exploration activities have confirmed expansive lithium mineralization across a number of project areas, with assay results of 66 rock samples released by ALS Laboratories earlier this year returning Li2O (lithium oxide) contents ranging up to 3.75 per cent Li2O (17,410 parts per million (ppm) lithium (Li)).

"Our 2023 Leinster lithium project exploration includes both drill and surface exploration programs," said Michael Murphy, chief executive officer of Global Battery Metals. "Without a doubt, the Knockeen prospect drilling is our top priority, but surface exploration and sampling continues across both northern and southern licensed areas. There's a lot or very promising ground to cover, and our priority target list continues to grow. We believe southeast Ireland is home to an untapped lithium district in the making."

Responsibility to the environment

All mineral exploration activities in Ireland take place under the auspices of the GSRO (Geoscience Regulation Office), a division within the government Department of the Environment, Communications & Climate Change. Exploration is governed under the framework of both Irish and EU (European Union) legislation that has been implemented to ensure that the environment is protected during exploratory work. Prospecting licence holders must comply with all of the relevant legislation. The company is pleased to confirm that it adheres to the highest standards of good practice in relation to its continuing exploration activities, having completed a detailed GSRO appropriate assessment process prior to commencement, which was reviewed, approved and signed off by the appropriate oversight authorities.

Competent person

All scientific and technical information in this announcement has been prepared under the supervision of, and reviewed and approved by, Vaughan Williams, EurGeol, MSc, PGeo, principal of Aurum Exploration Services (currently providing exploration services to Global Battery and to LRH Resources Ltd.), a qualified person within the meaning of National Instrument 43-101.

The Knockeen prospect forms part of the project exploration block, which is operated under an exclusive option and earn-in agreement with Technology Minerals PLC, the first listed United Kingdom company focused on creating a sustainable circular economy for battery metals, and its wholly owned subsidiary, LRH.

About Global Battery Metals Ltd.

Global Battery Metals is an international mineral exploration and development company with a focus on lithium and other metals that comprise and support the rapid evolution to battery power. Global Battery Metals currently maintains economic interests in four battery metal projects: (1) an option to acquire up to a 90-per-cent interest in the drill-ready Leinster lithium property in Ireland; (2) a 100-per-cent interest in the drill-ready Lithium King property in Utah; (3) an option to acquire up to a 100-per-cent interest in the La Poile lithium project in Newfoundland; and (4) a 55-per-cent stake in Peru-based Lara copper property, which has over 10,000 metres of drilling. As previously disclosed, Minsur SA, a Peruvian mining company, entered into an option agreement with Global Battery Metals and Lara Exploration Ltd. to acquire the Lara copper property for staged payments of $5.75-million (U.S.). Global Battery Metals will retain a 0.75-per-cent net smelter royalty (NSR).
