Patriot Announces Additional 2023 Drill Results at CV13 and

Provides Infrastructure Development Update, Corvette,

Quebec, Canada

February 25, 2024 – Vancouver, BC, Canada February 26, 2024 – Sydney, Australia

Highlights

• Patriot continues to intersect spodumene at the CV13 Pegmatite, with highlights:

o 22.5 m at 1.10% Li2O, including 15.2 m at 1.57% Li2O (CV23-300).

o 19.4 m at 1.20% Li2O (CV23-312).

o 16.1 m at 1.54% Li2O, including 7.2 m at 2.57% Li2O (CV23-319).

• The CV13 Pegmatite has been traced over a 2.3 km strike length, as defined by multiple

outcrop exposures and drilling completed to date, and remains open along strike at

both ends and to depth. The distance between CV5 and CV13 has now been traced

to ~3 km with ongoing drilling focused, in part, on closing this gap.

• Assays are reported herein for 15 drill holes completed in 2023 at the CV13 Spodumene

Pegmatite. For drill holes completed in 2023, results remain to be reported for an

additional 20 holes at the CV13 Pegmatite, 42 holes at the CV5 Pegmatite, and 18 holes

at the CV9 Pegmatite.

• At the Corvette Property i n 2024, t hrough February 22, a pproximately 23,000 m of

drilling have been completed – 21,200 m at CV5 and 1, 800 m at CV13 – with ten (10)

drill rigs active at site.

o Two (2) drill rigs are currently active at the CV13 Pegmatite as part of the ongoing

2024 winter drill program. The drilling is targeted to further delineate the principal

pegmatite body at CV13 along strike and downdip.

o The Company is mobilizing an additional drill rig as part of the winter drill program,

which will focus on geomechanical holes at CV5.

• An updated mineral resource estimate (“MRE”) for the Corvette Project, including both

CV5 and a maiden MRE for the CV13 spodumene pegmatites, is pla nned for Q3 2024,

with the focus of the MRE update to increase the confidence of the Inferred Resource.

• The Company’s exploration camp at KM-270 of the Trans-Taiga Road, Shaakichiuwaanan,

is operational at an initial 80 -person capacity, with a planned increase to at least a 132 -

persons later in the year.

• The 2024 winter program is entirely ground supported (i.e., no helicopters) , through a

combination of winter and all-season access road constructed by the Company, extending

from KM -270 of the Trans -Taiga Road to CV5 and through to CV13 , resulting in

dramatically reduced costs for the drill program.

• A geomechanical drill program at CV5 is anticipated to begin shortly , with geotechnical

and hydrogeological drill programs planned for this summer.

Patriot Battery Metals Inc. (the “Company” or “Patriot”) (TSX: PMET) (ASX: PMT)

(OTCQX: PMETF) (FSE: R9GA) is pleased to announce additional drill results from the 2023

program completed at the CV13 Spodumene Pegmatite , as well as recent infrastructure

development supporting the ongoing 2024 drill program at the Corvette Property. The Corvette

Property (the “Property” or “Project”), wholly owned by the Company, is located in the Eeyou

Istchee James Bay region of Quebec. The CV13 Spodumene Pegmatite is located approximately

3 km west-southwest of the CV5 Spodumene Pegmatite, which hosts a maiden mineral resource

estimate of 109.2 Mt at 1.42% Li2O inferred1 and is situated approximately 13.5 km south of the

regional and all‑weather Trans-Taiga Road and powerline infrastructure.

CV13 Pegmatite, 2023 Drill Results

Drill results for 15 drill holes completed in 2023 at the CV13 Spodumene Pegmatite are reported

herein (Figure 1). These holes primarily target the near -surface and downdip extension of the

principal pegmatite body along its western limb, as well as the eastern limb. Results include:

• 22.5 m at 1.10% Li2O, including 15.2 m at 1.57% Li2O (CV23-300).

• 19.4 m at 1.20% Li2O (CV23-312).

• 16.1 m at 1.54% Li2O, including 7.2 m at 2.57% Li2O (CV23-319).

• 13.8 m at 1.16% Li2O (CV23-320).

The drilling continues to trace spodumene pegmatite at CV13 to the west -northwest along

geological trend and remains open along strike and downdip in this area. R esults remain to be

reported for twelve (12) drill holes, covering approximately 300 m of strike, over the far portions

of this western limb. The mineralized pegmatite in this area has a shallow northeasterly dip

resulting in pegmatite being traced down dip for over 250 m with minimal drilling, while still only

being approximately 100 m vertical depth below surface – see geological cross-section in Figure

2, which includes drill holes CV23-305 and 312 as reported herein.

Results are also reported herein for one ( 1) hole completed in 2023 (CV23 -300, noted below)

within the apex of the regional host structure at CV13. One (1) drill hole (CV23-302) completed

in 2023 remains to be reported from this area (Figure 1).

• 22.5 m at 1.10% Li2O, including 15.2 m at 1.57% Li2O (CV23-300).

Results reported herein for drill holes completed over the eastern limb of the CV13 Pegmatite

(CV23-293, 299, 301, and 306) returned only minor intervals of pegmatite ranging from <2 m to

5.8 m (core length). However, the pegmatite remain s well mineralized in drill holes CV23 -299

(4.7 m at 1.38% Li2O) and CV23-293 (2.7 m at 1.10% Li2O). The pegmatite dyke thins in this area

of the eastern limb; however, is confirmed to thicken moving northeast erly along strike as

evidence from drill holes completed in 2022. Results for six (6) drill holes completed in 2023

along the eastern limb of CV13 remain to be reported (Figure 1).

The CV13 Pegmatite is currently interpreted to be characterized by a principal “upper” dyke and

a secondary “lower” dyke, as well as several subordinate sub -parallel dykes, and are collectively

geologically modelled to be shallowly dipping northerly. The principal dyke (the “upper” dyk e),

dips typically between 20-25° and has been traced at depth to at least 300 m down- dip (vertical

depth from surface of ~140 m). The principal dyke at CV13 has been traced over a 2.3 km strike

length, as defined by multiple outcrop exposures and drilling completed to date, and remains

open along strike at both ends and to depth.

In 2024, through February 22, approximately 23 ,000 m of drilling have been completed at

Corvette – 21,200 m at CV5 and 1, 800 m at CV13 – with ten (10) drill rigs active at site ( see

Figure 3 and Figure 4). Two (2) of the ten (10) drill rigs are currently active at the CV13 Pegmatite.

The drilling at CV13 is targeted to further delineate the principal pegmatite body along strike and

downdip. An updated mineral resource estimate for the Corvette Project, including both the

CV5 and CV13 spodumene pegmatites, is planned for Q3 2024.

Core sample assays for drill holes reported herein are presented in Table 1 for all pegmatite

intersections >2 m. Drill hole locations and attributes are presented in Table 2. For drill holes

completed in 2023, results remain to be reported for the CV13 Pegmatite ( 20 holes), the CV5

Pegmatite (42 holes), and the CV9 Pegmatite (18 holes).

Infrastructure Development

The 2024 winter drill program is entirely ground supported, utilizing the all- season/winter road

constructed by the Company, which extends south from KM-270 of the Trans-Taiga Road to the

CV5 Spodumene Pegmatite (Figure 3, Figure 4, and Figure 5). The winter portion of this road has

been further extended westerly to support drilling at the CV13 Spodumene Pegmatite. No

helicopters are currently active at site due this infrastructure now emplaced and in daily use.

The Company’s exploration camp at KM-270 of the Trans-Taiga Road has been operational since

early January at an initial 80-person capacity, with an anticipated increase to at least 132 -person

later in the year (Figure 6). After consultation with elders from the Cree Nation of Chisasibi by

the tallyman and his family, the camp has recently been formally named the Shaakichiuwaanan

Camp (pronounced Shaa-gi-chi-waa-nan), a Cree word meaning "to climb up a hill or mountain".

The camp is located only 13 km directly north of the CV5 Pegmatite, thereby dramatically

reducing the transport time of field staff to and from the drill area.

The combination of the Company’s exploration camp on the Trans-Taiga and direct access roads

to the CV5 and CV13 pegmatites have dramatically reduced the costs of the drill program through

more cost-effective staff movement, reduced transport time, reduced accommodation costs, and

reduced time for drill moves.

In addition to the camp and road infrastructure development, the Company anticipates

completing a geomechanical drill program this winter at CV5. Data from this drilling and sampling

will provide key datapoints to assess pit slope stability and design. This work will be followed in

the summer by an infrastructure and condemnation geotechnical drill program, which will include

potential tailings and waste rock storage sites, process plant, and camp accommodations for

operation. A phase II hydrogeological drill program at CV5 is also planned for the summer, which

will build upon the preliminary hydrogeological model completed in 2023.
