Global Battery Metals Announces Start of Drill Program at Leinster Lithium Project in Ireland

May 10, 2023

Drilling Now Underway at Knockeen Prospect

May 10, 2023, Vancouver, British Columbia – Global Battery Metals Ltd. (the “Company” or “GBML” or “Global Battery Metals”) (TSXV: GBML; OTCQB: REZZF; Frankfurt: REZ), a critical mineral exploration company focused on growth-oriented lithium and battery metal projects, is pleased to announce the commencement of its multi-stage diamond core drilling program (the “Drill Program”) at the Leinster Lithium Project (the “Project”) in County Carlow, Ireland. This inaugural Drill Program has been approved for up to 10 drill holes.

Phase 1 drilling is focused on Prospecting License Area 1597 (the “Knockeen Prospect”) and will comprise four drill holes for approximately 1,000 metres of diamond core drilling. The drilling will take place across previously announced prospective lithium pegmatite trend targets which includes the historically reported trenched bedrock occurrence which is coincident with several highly anomalous LCT Pegmatite (lithium-cesium-tantalum pegmatite) geochemical trends. This, in conjunction with the broad spodumene pegmatite boulder train at surface, has been interpreted to indicate the presence of up to six potential dikes.

The Drill Program has received all necessary government approvals through the Geoscience Regulation Office (GSRO) which covers all aspects of environmental best practice procedures. This is carried out through the detailed Appropriate Assessment Screening Programme which was approved in April.

“Europe and the US are both pushing for lithium independence and continue to seek out viable parties that can deliver the full package – future access to high-grade domestic lithium supplies through partners that understand and appreciate all of the geopolitical and commercial considerations at stake,” said Michael Murphy, CEO of Global Battery Metals. “This will most definitely include battery metal companies operating in the junior mining space that can execute against resource delivery and relationship management with equal intensity. We look forward to continued progress at Leinster and with the associated business discussions all underway.”

The results of Phase 1, including all metallurgical testing and other exploration activities completed during this time, will be used to inform Phase 2 drilling. As previously noted, significant sampling and mapping across the Knockeen Prospect was conducted in recent months, with the potential discovery of up to six LCT pegmatite dikes (see March 20, 2023, press release) and the most recent assay results of 66 rock samples released by ALS Laboratories returning Li2O% lithium contents ranging up to 3.75 % Li2O / 17,000 ppm Li (see January 18, 2023, press release).

About the Leinster Lithium Project

The Project, located in the counties of Wicklow and South Carlow, in the Republic of Ireland, is a lithium pegmatite project that consists of 16 prospecting license areas located SW of Dublin and in direct proximity to the joint venture Ganfeng Lithium / International Lithium Corporation Blackstairs Lithium Project. Lithium mineralization has been confirmed across all Project areas explored to date, with the potential discovery of up to six LCT pegmatite dikes and assay results of 66 rock samples released by ALS Laboratories returning Li2O% lithium contents ranging up to 3.75 % Li2O / 17,000 ppm Li at the Knockeen Prospect. The Project’s maiden Drill Program is permitted for up to 10 drill holes, with Phase 1 drilling now underway.
