GLOBAL BATTERY METALS SIGNIFICANTLY EXPANDS LAND POSITION AT LEINSTER LITHIUM PROJECT WITH ADDITIONAL OPTION AGREEMENT

Global Battery Metals Ltd. has arranged a strategic expansion of its Leinster lithium project exploration activities with the exclusive option to acquire six (four granted/two under application) additional southern licence block mining claims covering an additional 249 square kilometres. The new Claims border the Company's PL 1597 Knockeen Lithium Pegmatite Project and are situated along the southwest strike with the recently discovered LCT pegmatite dike swarm (see Map 1 below).

Key Highlights:

• Secures option to acquire six new contiguous licenses (four granted/two pending under application) covering an additional 249 km2 adjacent to its Knockeen Lithium Pegmatite Project, more than quadrupling its southern license land position;
• New licences strategically situated to extend GBML's exploration of a new and significant lithium-bearing spodumene pegmatite system at PL 1597, progressing SW and in-line with the East Carlow Deformation Zone ("ECDZ");
• Recent near-surface trenching chip sample assays from one of the pegmatite dikes show values of up to 2.55% Li2O at a depth of only 2m in the NE-SW trending dike swarm; and
• Total project package now consists of 22 prospecting licenses covering ~775 km Superscript 2, situated along strike to Blackstairs Lithium (Ganfeng / ILC joint venture) Avalonia Project.

Coming on the heels of GBML's recent lithium pegmatite trenching results at Knockeen and 2.55% Li2O chip sample taken at a depth of just two metres (2m), as well as its earlier successful first round of exploration drilling at Knockeen which recorded 24 intervals of near-surface lithium intersects across nine holes, the decision was made to enter into an option agreement (the "Option Agreement") with Tancred Resources Ltd. ("Tancred") in order to secure the rights to select neighboring Claims. In total, the full Leinster Lithium Project footprint now comprises 22 mineral claims covering approximately 775 km2 and is situated along strike to nearby Blackstairs Lithium's Avalonia Project (297 km2 joint venture between Ganfeng Lithium Co. Ltd and International Lithium Corp.).

The Claims tactically augment GBML's existing holdings along and adjacent to the important East Carlow Deformation Zone, which is interpreted to control the emplacement of an existing LCT pegmatite field at the Blackstairs Mountains. Exploration data for the new Claims include soil geochemistry, magnetic and gravity surveys and mapping. The current information highlights the presence of chemical trace elements associated with LCT pegmatite which, coupled with the identified spodumene bearing pegmatites from 2023 drilling at Leinster, suggest that the LCT pegmatite field identified at the Blackstairs extends to the southwest, on the grounds covered by this acquisition.

Michael Murphy, CEO of Global Battery Metals, underscored the importance of this expansion, stating: "Knowing what we now know about the near-surface opportunities and consistency that we're seeing in this NE-SW trending dike swarm, seizing this strategic expansion opportunity was an easy decision to make. GBML has had our eye on these additional licenses for some time now, but up until recently the land was unavailable. Given the proximity to not only our own active exploration, but also to Blackstairs Lithium's expansive drill program plans, GBML's new southern tract of project licenses is a significant district addition. We've been tracking exploration progress in and around PL 1597 throughout 2023, and have seen the focus area expand in lockstep with favourable geologic reporting. We thank the Tancred team for their partnership and we are looking forward to expanding our exploration efforts."

The Agreement

The Option Agreement follows previous option agreements that GBML has entered into with a modest upfront payment and a timeline that provides GBML adequate time to consider the property's merit.

Pursuant to the Option Agreement, GBML may acquire a maximum of 100% legal and beneficial interest in the Claims, including all other assets acquired or held by GBML or Tancred with respect thereto or pursuant to the Option Agreement (together with the Claims, the "Assets") upon fulfilment of the conditions below:

• GBML shall pay Tancred $25,000 in cash, within 3 business days following the date of the Option Agreement (the "Execution Date");within 18 months after the Execution Date, GBML shall issue to Tancred (i) 500,000 common share purchase warrants with a strike price of $0.30 exercisable 18 months following the issuance date of such warrants, and expiring 42 months following the Execution Date ("Warrants"), and (ii) such number of common shares in the capital of GBML ("Common Shares") as shall have a value equal to $75,000 (provided that no more than 750,000 Common Shares shall be issued). Upon satisfaction of these conditions, GBML shall be deemed to have acquired a 25% interest in the Assets (the "First Interest");
• within 30 months after the Execution Date, GBML shall issue to Tancred such number of Common Shares as shall have a value equal to $200,000 (provided that no more than 2,000,000 Common Shares shall be issued). Upon satisfaction of these conditions, GBML shall be deemed to have acquired an aggregate of 51% interest in the Assets (the "Second Interest"); and,
• within 42 months after the Execution Date, GBML shall issue to Tancred such number of Common Shares as shall have a value of $300,000 (provided that no more than 3,000,000 Common Shares shall be issued). Upon satisfaction of these conditions, GBML shall be deemed to have acquired 100% interest in the Assets (the "Third Interest").

Upon acquiring the Third Interest and the satisfaction of certain conditions as described below, Tancred may be eligible to receive performance shares, as follows:

• upon the announcement of 5 mt at concentration of 1% Li2O at the property, such number of Common Shares as shall have a value of $1,000,000, provided that no more than 10,000,000 Common Shares shall be issued;
• upon the completion of a Feasibility Study, such number of Common Shares as shall have a value of $2,000,000, provided that no more than 20,000,000 Common Shares shall be issued; and,
• upon commencement of Commercial Production, such number of Common Shares as shall have a value of $2,000,000, provided that no more than 20,000,000 Common Shares shall be issued.

In these three instances, the number of Common Shares issued shall be equal to such maximum number of Common Shares that may be issued to Tancred without Tancred becoming an Insider of GBML. Furthermore, should GBML decide not to exercise its option to acquire the Second or Third Interest, the number of performance shares and their corresponding dollar values shall be proportionately reduced/adjusted to match the percentage of interest acquired by GBML.

The Option Agreement remains subject to the final approval of the TSX Venture Exchange.

About the Leinster Lithium Project

Located south of Dublin in the counties of Wicklow and South Carlow, the Leinster Lithium Project consists of 22 prospecting license areas covering approximately 775 km Superscript 2 situated along strike to Blackstairs Lithium's Avalonia Project (297km Superscript 2 joint venture between Ganfeng Lithium Co. Ltd. and International Lithium Corp.). All of GBML's license holdings are located within or along the important East Carlow Deformation Zone, which is interpreted to control the emplacement of an existing LCT pegmatite field at the Blackstairs Mountains.

With first phase drilling concluded at Knockeen, GBML has succeeded in identifying a new and structurally controlled LCT pegmatite system of significance, importantly recording 24 intervals of lithium bearing spodumene pegmatites intersected across nine holes drilled. The spodumene pegmatites range in width between 0.10m up to 0.63m (true width) with the highest values grading up to 2.57% Li2O. No drilling has ever been carried out at the Knockeen Prospect previously and intersecting lithium bearing pegmatites in all of the holes drilled so far is considered a major technical success for the Company. Prior surface exploration activities identified and confirmed expansive surface boulder trains of lithium pegmatite lithologies in a number of areas across the Company's property, with recent assay results of 66 rock samples analyzed by ALS Laboratories earlier this year returning Li2O% lithium contents ranging up to 3.75% Li2O / 17,410 ppm li.

Responsibility to the Environment

All mineral exploration activities in Ireland take place under the auspices of the GSRO, a division within the Government Department of the Environment, Communications & Climate Change. Exploration is governed under the framework of both Irish and EU 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 ongoing 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. GBML's Directors understand that social license is key to unlocking positive exploration outcomes by following low impact / low sound / low disturbance exploration program best practice for environmental sensitivity.
