Rhea-AI Summary

Global Battery Metals Ltd. (TSXV: GBML) (OTCQB: REZZF) (FSE: REZ) reports the completion of the first phase of drilling in SE County Carlow, Ireland, confirming a new LCT pegmatite system with lithium grades up to 2.57% Li2O. The drilling program defined a significant swarm of pegmatite dikes, with 24 intervals of lithium-bearing spodumene pegmatites intersected across nine completed holes.

24 Lithium Bearing Pegmatite Intersects Recorded Across Nine Completed Holes; Drilling Confirms New Bedrock LCT Pegmatite System with Grades Up to 2.57% Li2O

Vancouver, British Columbia--(Newsfile Corp. - November 15, 2023) - Global Battery Metals Ltd. (TSXV: GBML) (OTCQB: REZZF) (FSE: REZ) (the "Company" or "GBML" or "Global Battery Metals"), an international critical mineral exploration company focused on growth-oriented lithium and battery metal projects, is pleased to announce that the inaugural first phase of drilling has been completed on its Knockeen Lithium Pegmatite drill program in SE County Carlow, Ireland. Focussing on a Lithium-Cesium-Tantalum (LCT) pegmatite dike swarm, the first nine holes were completed in late October for a total of 2,022m. All nine holes successfully intersected lithium bearing Lithium LCT Pegmatites. Samples were submitted to ALS Laboratories in County Galway and analyzed using the specific ME-MS89L Lithium Pegmatite analytical suite which are now reported.

Key Highlights:

• Drilling has confirmed and further defined a swarm of pegmatite dikes within host granites to reveal a new, structurally controlled LCT pegmatite system of significance;
• 24 intervals of lithium bearing spodumene pegmatites were intersected across the nine holes drilled and show that the pegmatites are all broadly parallel with a strike of NE-SW;
• 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 in Intercept 15 in Hole 23-1597-06;
• Values grading over 1% Li₂O were recorded in five of the nine holes drilled (Hole 23-1597-01, Hole 23-1597-02, Hole 23-1597-06, Hole 23-1597-07 and Hole 23-1597-09) with a sixth hole (Hole 23-1597-03) just shy of the 1% mark reporting a 0.96% Li₂O intersect; and
• The project area is situated within the same tectonic zone and along strike to Blackstairs Lithium (Ganfeng / ILC joint venture) Avalonia Project.

Michael Murphy, CEO of Global Battery Metals, underscored the importance of these initial assays, stating: "Until now, Knockeen has been defined by surface mapping and sampling, along with its strategic location within the East Carlow Deformation Zone and close proximity to Ganfeng and ILC's exploration activity. Our expressed goal to confirm lithium mineralization in our first round of exploration drilling has been achieved, and hitting consistent, near-surface lithium intersects in a brand-new area has the entire team very excited. We've done our homework, including years of geological data collection and hands-on exploration to assess Leinster's lithium potential, and we're taking additional cues and clues from our first-round drilling to further evolve our exploration strategy. In this case, we plan to make calculated, district-scale moves. We've drilled into fingertips and intend to follow these fingers to a wider body."

Assay Results Interpretations and Next Steps

The drilling program defined a swarm of pegmatite dikes across the Knockeen zone with all holes (23-1597-01 to 09) intersecting lithium bearing spodumene pegmatites, seven of which reported multiple intersections. The drill holes were focused in three areas north-east (holes 1-4), central (holes 5-6) and south-west (holes 7-9). The drilled extension of the pegmatite dyke swarm is 500m on strike and extends about 200m vertically. The target area is still open in all directions and also at depth and these aspects will be the focus for the next stage of exploration activities.

Initial interpretation of the pegmatite dike intercepts show that the pegmatites are all broadly parallel with a strike of NE-SW with some minor degrees of inflection across the drilled strike length. The pegmatites are all dipping to the north west with slightly variable dips of between 35-50 degrees. The spodumene pegmatites range in width between 0.10m up to 0.63m (true width) with the best individual sample interval grading up to 2.57% Li₂O in Pegmatite 15 (Sample AES65298) in Hole 23-1597-06.

This first phase of Knockeen drilling has been key in setting the scene to establish the geometry and nature of the pegmatites in an entirely new area where there is no surface outcrop, no historical drilling and a single short historical trench. The placing of the target area within the bounds of the interpreted East Carlow Deformation Zone is a key factor in developing the prospect further. Detailed structural and petrological studies will now commence at both the regional and drill core scale to interpret the structural regime of emplacement of the spodumene pegmatites and to determine the geometric model to guide the next phase of drilling. This work has already commenced with the creation of a 3D exploration model in Leapfrog utilizing the several thousands of structural readings collected from the orientated drill core.

The Company also intends to invite additional industry experts in the field of LCT pegmatites and structural geology interpretation to view the drill core at its core shed to help place all of the information collected to date in a detailed structural and lithological framework of the SE Leinster Massif. This will help develop strategies for further exploration work on both this license as well as the rest of the Company's license holdings.

Sampling and Chain of Custody

All holes were drilled by diamond coring at HQ drill core size (63.5mm diameter). The drill core retrieved from the core barrel was continuously measured for exact orientation by the driller using a Reflex EZ-Trac Single Shot down-hole core orientation tool on the drill rig. Once back at the core shed detailed structural measurements could then be measured in the drill core with an IMDEX STRUCTURAL-IQ™ Solution tool as part of the core logging process. This approach means that the pegmatites and their exact orientations can be positioned with all of the other structural components relating to the emplacement of the pegmatite dike swarm.

Logging and sampling of the holes took place at the Company's core shed and all samples were run through a tightly controlled chain of custody and rigid QA/QC sampling process which included regular insertion of certified reference materials including standards, blanks and sample duplicates. All samples were submitted to ALS Laboratories in County Galway and analyzed using the specific ME-MS89L Lithium Pegmatite analytical suite offered by the laboratory.

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 525 km² 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 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 lithium.

Decision Made to Exit La Poile Exploration Program

GBML also announces that the Company has discontinued exploration activity at the La Poile Project in Newfoundland and has elected to terminate the property option agreement dated November 8, 2021. This decision was reached following the conclusion of a previously announced 2023 exploration program. Initial exploration of the La Poile Project began in 2022 during which several pegmatite dikes were discovered and sampled but were not found to be Li-bearing.

"Exploration activities at La Poile have not generated the type of results needed to shift any subsequent attention away from accelerating our Leinster Lithium Project expansion efforts. I want to also be very clear that drilling Lithium King this year remains a priority," Murphy added.

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 of drill core samples and associated assay results are monitored by GBML through a quality assurance/quality control ("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 meters 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 of 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.
