Global Battery Metals Initiates Exploration Program at Sawyer Camp Nickel-Copper Project with Geophysics Survey

Company Provides Corporate Update on Full Portfolio of Projects Underway

Vancouver, May 9, 2022 - Global Battery Metals Ltd. (TSXV: GBML) (OTCQB: REZZF) (FSE: REZ) (the "Company" or "GBML"), an international critical mineral exploration and development company focused on growth-oriented battery metal projects supporting the global transition to clean energy, today announces it has contracted Crone Geophysics & Exploration Ltd. to complete a surface Time Domain Electromagnetic (TDEM) survey over targets identified at its Sawyer Camp Nickel-Copper Project in the Upper Peninsula of Michigan. TDEM surveys have been used extensively to aid in locating nickel, copper and other base metals accumulation, with survey data being used to inform drill program targets moving forward. GBML anticipates being in-field by mid-June.

"GBML is excited to commence field exploration work at our Sawyer Camp Project, as it shares similar characteristics to other nearby properties that are producing including Eagle Mine," stated Michael Murphy, President and CEO of GBML. "Our plan is to mobilize with Crone quickly. The Company is testing for the presence of Eagle-style nickel sulphide deposits under Paleozoic cover, allowing us to zero in on exploration targets and drill hole locations during this current field season."

Additionally, the Company is also pleased to provide a progress report on each of its other battery metal prospective projects - all expected to advance over the coming month.

Key updates include:

• Lithium King (Lithium), Utah - the Company anticipates securing the BLM drill permit soon to evaluate stratigraphy and basement depth and will update the market accordingly. The project jurisdiction and size remain appealing as shallow sampling suggests favourable grade potential.

• NW Leinster (Lithium), Ireland - a new exploration permit is expected shortly with the immediate priority of identifying a drill target at the Aghavannagh Prospect where large angular blocks of spodumene pegmatite (float) has returned promising economic grades of Li2O. A work plan for this and other programs across the block will be shared soon after.

• Lapoile (Lithium), Newfoundland - GBML will be getting into the field this summer for initial exploration and geological mapping work. Government till samples are higher here than nearby properties already experiencing exploration success.

• Lara (Copper), Peru - 55% owned by GGML; an option was granted to Minsur (a large, private Peruvian mining company operating a nearby copper mine) with staged acquisition payments, of which the first two payments have already been made. Minsur continues to work on the property with GBML retaining a 0.75bpt royalty.

"For years, Global Battery Metals has been actively building a core group of projects to support the clean energy-driven demand for critical minerals that we're now experiencing," continued Mr. Murphy. "All of these properties are now close to falling in place and we intend to be much more investor-engaged throughout 2022 given what we have in our opportunity pipeline."
