Global Battery Metals Completes Initial Knockeen Trench Sampling

Program at Leinster Lithium Project, Ireland

Company submits near surface trenched spodumene pegmatite samples to lab for

expedited assay testing

Vancouver, British Columbia – December 7, 2023 – Global Battery Metals Ltd. (the “Company” or

“GBML” or “ Global Battery Metals ”) (TSXV: GBML; OTCQB: REZZF; Frankfurt: REZ), an

international critical mineral exploration company focused on growth -oriented lithium and battery metal

projects, is pleased to announce it has completed the recent shallow trench sampling program at its

Knockeen lithium pegmatite project located on GBML’s Leinster Lithium Project in Ireland.

Highlights:

• A cross-cut trench of approximately 25m in total length was successfully opened up at 1-2m depth

to confirm a historically reported 1.8m wide spodumene bearing pegmatite dike.

• Samples collected at 1m intervals along the exposed strike length of the dike were submitted for

expedited lab testing with results delivery anticipated mid-December.

• Rock and soil assay results will be used for 2024 exploration planning of the prospect and at several

other target areas on the licence property.

Michael Murphy, CEO of Global Battery Metals, said: “We’re moving fast to see these assays. The team

is pleased to confirm the historic dike target location and complete initial surface trench sampling before

year end. At only two metres deep, these trenching sample assays are important as they’ll give us a clear

view into the near surface lithium mineralization opportunity that we believe exists. We are preparing now

for our next exploration steps at Knockeen and surrounding areas, and believe that we’ll see an active and

busy lithium discovery district take shape early in 2024.”

The intersected pegmatite in the trench contained spodumene crystals along its full exposed length and five

chip samples were collected at 1m intervals along its exposed length (see Image 1). These samples , along

with several grab samples from large blocks of pegmatite in the trench (see Image 2) , are also being

analyzed by ALS Laboratories in Ireland.

Trench Details

The current trench was fully permitted through the Geoscience Regulation Office (GSRO) of the

Department of Environment, Climate and Communications. The trench was designed to confirm a

historically reported trench ed spodumene pegmatite dike occurrence which was intersected over 1.8m

width but with no assay data reported from this time. The current trench lies 25m along trend to the east of

the old trench and forms a “T” shape by first cross cutting the dike with a 25m N-S trench and then exposing

the dike along its length to the west towards the historical trench occurrence. Work on this small footprint

of field area was undertaken in close association with the landowner and the Company will rehabilitate the

trenched area back to the original field condition on completion (see Image 3).

The trenching will also assist in the interpretation of the spodumene bearing pegmatite dikes encountered

in the 2023 summer drilling program. The dike dips northwestwards at approximately 40 degrees. This

trench pegmatite is interpreted to be the same pegmatite intersected at 30m depth in drill hole 23-1597-02

and at 60m depth in drill hole 23-1597-03. This gives a total down dip extension of at least 100m from

surface. This dike is just one of the spodumene bearing dikes intersected in the drilling which form a

broadly NE-SW trending dike swarm of up to seven dikes in 24 separate intercepts in nine diamond cored

drill holes.

Detailed soil profile sampling was also conducted along the length of the main N-S trench to determine the

best soil sample medium, A-B-C horizon to locate bedrock pegmatites below surface. This information will

be used to help plan further broader reaching shallow soil geochemistry surveys.

Geology & Structure

The property lies along part of a 135km long regional structural trend of known lithium-bearing pegmatite

bedrock occurrences, situated along the south -eastern margin of the Leinster Granite Massif and centred

on the Aclare and Moylisha occurrences which were discovered during 1960s and 1970s and are currently

being explored by Blackstairs Lithium (under the Ganfeng – International Lithium joint venture).

This trend is focused along and within a broad regional NE -SW trending structural zone termed the East

Carlow Deformation Zone (“ECDZ”) which runs for over 135km along the SE flank of the Leinster Granite

Massif between Dublin in the NE and north of New Ross to the SW. A recent detailed regional structural

review and interpretation by the Company using remote sensing data and regional geophysical data sets

confirmed that PLA 1597 lies within the key ECDZ structural zone.

The Knockeen target area lies directly within this zone as it passes through the northern margin of the

Backstairs Granite Pluton whilst the southern part of the license is cross cut by a splay of the ECDZ which

passes south westwards along the southern ma rgin of the Backstairs Granite Pluton. This southerly splay

has been termed the North Wexford Deformation Zone ( “NWDZ”) and provides a second highly

prospective trend for the focus for ground exploration activities Several target areas have already been

identified for detailed prospecting and mapping which will commence over the coming months.

About the Leinster Lithium Project

Located south of Dublin in the counties of Wicklow and South Carlow, the Leinster Lithium Project

consists of 16 prospecting license areas covering approximately 525km² situated along strike to nearby

Blackstairs Lithium’s Avalonia Project (297 km² 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 pegmati tes 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 legislati on that has been implemented to ensure that

the environment is protected during exploratory work. Prospecting license 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.

Competent Person

All scientific and technical information in this announcement has been prepared under the supervision of

and reviewed and approved by EurGeol Vaughan Williams, M.Sc., P.Geo., (Principal of Aurum

Exploration Services currently providing exploration services to GBML and to LRH Resources Limited),

a “qualified person” within the meaning of National Instrument 43-101.

Quality Assurance/Quality Control

Quality Assurance/Quality Control (“ QA/QC”) of drill core samples and associated assay results are

monitored by GBML through a QA/QC protocol which includes the insertion of blind standard reference

materials, blanks, and duplicates at regular intervals. Core is drilled in HQ core diameter and each 3 metres

of core recovered is orientated by the drilling contractor on completion of each run drilled. Drill core is laid

out in strong core boxes and transported by Company geologists from the drill rig to GBML' s secure

logging facility. Drill core is then logged using an established logging procedure capturing detailed

lithological data as well as measuring all structural elements using a Reflex IQ Logger for accurate

orientation of all contacts and structures. The core is marked up for sampling and sawn on site using a

diamond core saw. Half core samples are then bagged and secured using plastic cable ties and the samples

are then securely transported to ALS Laboratory (“ALS”) facilities in County Galway, Republic of Ireland.

Samples are analyzed for lithium as well as multi - elemental trace elements using the specific LCT

pegmatite analytical suite ME -MS89L offered by ALS. ALS also performs its own internal QA/QC

procedures to assure the accuracy and integrity o f results. GBML is unaware of any drilling, sampling,

recovery, or other factors that could materially affect the accuracy or reliability of the data referred to

herein.
