Exploration Program Update

Company confirms field geochemical exploration program is advancing on schedule

and announces a well-defined spodumene pegmatite boulder train on PL 1597.

November 15, 2022, Vancouver, British Columbia – Global Battery Metals Ltd. (the “Company” or

“GBML”) (TSXV: GBML; OTCQB: REZZF; Frankfurt: REZ), an international critical mineral

exploration and development company, announces field exploration work is advancing on schedule on

its North-West Leinster Lithium Project (the “Property” or the “Project”), with a particular focus on

Prospecting Licence Area (“PLA”) 1597.

PLA 1597 forms part of the Company’s Property exploration block, which is operated under an

exclusive Option and Earn-in agreement with Technology Minerals Plc (LSE: TM1)*.

Exploration Highlights:

• Field geochemical exploration programs advancing on schedule.

• The first target area in the vicinity of the historical spodumene bearing trench at Knockeen East

is being targeted by a closely spaced deep overburden sampling program (Figure 2).

• The area is also undergoing intensive prospecting which is c onsolidating the extent of the

spodumene pegmatite boulder train as well as significantly enhancing the resolution of the

dispersion zone and, therefore, the target potential drill target areas. See example of spodumene

bearing boulder in Photo 1.

• A total of 46 rock samples and 233 deep overburden samples along with 13 QAQC samples

have been collected to date and submitted to ALS Laboratories for analysis.

• Deep overburden sampling and prospecting is continuing across the survey grid area and will

migrate to the second target area at Carriglead in due course.

• This work is being carried out to help determine specific areas for follow up drilling.

Target focus PLA 1597

PLA 1597 was identified as prospective for lithium pegmatite potential by the Company’s Project

partner LRH and its exploration consultants Aurum Exploration Services (“Aurum”) following detailed

desktop studies, which outlined two proximal areas of spodumene-bearing pegmatite, as reported by

previous operators in the mid-1970s. Initial prospecting by the Company confirmed a high grade

spodumene bearing pegmatite boulder dispersion train during prospecting survey at two localities

(Figure 1) . R esults from the six samples returned values between 0.70% Li 2O to 2.95% Li 2O at

Knockeen and Carriglead, as previously disclosed by the Company (see news release of October 19,

2022).

Field Exploration Program Update

The current phase of detailed exploration work is centred on a location described in a 40-year-old

historical report describ ing a trench excavated at Knockeen Townland on PLA 1597 as having

uncovered in bedrock a 1.8m wide spodumene -bearing pegmatite dyke. H owever, no detailed

laboratory assays or geological maps of t he trench were reported at that time. Historical prospecting

around the trench also reported the occurrence of up to 10 large boulders of spodumene bearing

pegmatite at surface, some of which may have come from the pegmatite dyke historically intersected in

the trench.

The current exploration program is utilizing a well tried and tested geochemical exploration technique

called Pionjar or Deep Overburden Sampling. This technique uses equipment to penetrate the soil and

glacial till down to the bedrock interface where a sample is collected for analysis. The depth of the

sampled material varies between 1m and 5m at Knockeen . This techni que is more accurate than

sampling the surface soil material as the sample point is closer to the bedrock source of the lithium

bearing pegmatites and helps to remove the effects of geochemical dispersion at higher levels in the

overburden profile.

The first part of the two-stage program has been carried out on an initial closely spaced grid (Grid 1:

Figure 2) over the area of the historical trench on 25m spaced lines with samples collected at 15m

intervals or stations. The second stage is in progress, extending westwards following the trend of the

spodumene pegmatite boulder train and termed Grid 2. This grid will cover a larger area at 50m line

spacing and 30m sample intervals (Figure 2).

The field program commenced mid-October and will continue to late November . A total of 233 deep

overburden samples along with 13 QAQC samples have been collected to date and submitted to ALS

Laboratories for analysis. Results are pending.

In association with the deep overburden sampling a detailed program of prospecting is also ongoing

and to date 46 rock samples have been collected and submitted to ALS Laboratories for analysis. Subject

to any delays in the analysis of the samples, the results for the entire program are expected to be returned

by the end of 2022.

Once the two grids at Knockeen are completed the team will move to the second target area at

Carriglead, two kilometres to the south where a simila r historical ly reported and since verified

spodumene pegmatite boulder train has been identified (see Figure 1).
