Patriot Extends Strike Length to 4.35 km at the CV5 Spodumene

Pegmatite, Corvette Property, Quebec, Canada

September 24, 2023 – Vancouver, BC, Canada September 25, 2023 – Sydney, Australia

Highlights

• Extension of the CV5 Spodumene Pegmatite by 650 m to the west.

o Multiple drill holes have returned continuous core -length spodumene pegmatite

intersections exceeding 30 m, and up to 56.8 m (drill hole CV23-231).

o Multiple drill holes have returned composited core -length pegmatite intersections

(i.e., sum of all pegmatite intervals within the hole) of over 90 m, to a peak of

approximately 144 m (CV23-223).

• The CV5 S podumene Pegmatite has now been traced continuously by drilling over a

lateral distance of at least 4.35 km and remains open.

• Fifty-three (53) drill holes, totalling approximately 15,614 m, have been completed through

September 18, 2023, at the Corvette Project.

o Thirty (30) holes (~10,757 m) completed at the CV5 Spodumene Pegmatite.

o Twenty (20) holes (~4,707 m) completed at the CV13 Spodumene Pegmatite.

o Three (3) holes (~150 m) completed at KM-270 camp site (for hydrogeology).

• Initial drill testing of the CV9 Spodumene Pegmatite cluster has recently commenced.

• Assays are currently pending, however with core sample shipments on a weekly basis it is

anticipated that assay results will start to be received later in October. With such a high

volume of samples from across multiple drill targets , the results will be collected and

released by area for clarity.

• A total of seven (7) drill rigs are currently active at site – four (4) at CV5, two (2) at CV13,

and one (1) at CV9. Drilling is anticipated to continue into December and will recommence

after the holidays with ten (10) drill rigs targeted by mid January 2024.

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

(OTCQX: PMETF) (FSE: R9GA) is pleased to provide an update on the ongoing 2023 summer-

fall drill program being completed at its wholly owned Corvette Property (the “Property” or

“Project”), located in the Eeyou Istchee James Bay region of Quebec. The Property hosts the CV5

Spodumene Pegmatite, with a maiden mineral resource estimate of 109.2 Mt at 1.42% Li 2O

inferred1 and is situated approximately 13.5 km south of the regional and all-weather Trans-Taiga

Road and powerline infrastructure.

Since the completion of the winter drill program in April 2023 (through drill hole CV23-190), and

the release of a maiden mineral resource estimate for the CV5 Spodumene Pegmatite (see news

release dated July 30, 2023), drilling at the Property has focused on westerly step-outs and further

delineation at CV5 (30 holes totalling ~ 10,757 m), as well as continued delineation at the CV13

Spodumene Pegmatite (20 holes totalling ~4,707 m).

The Company is pleased to report that through September 18, 2023, the summer drill program at

CV5 has extended the spodumene pegmatite an additional 0.65 km along strike to the west.

The CV5 Spodumene Pegmatite has now been traced continuously by drilling (at approximately

50 to 150 m spacing) over a lateral distance of at least 4.35 km and remains open along strike

at both ends and to depth along most of its length ( Figure 1, Figure 2, and Figure 3). Over this

extension, multiple drill holes have returned continuous core-length spodumene pegmatite

intersections exceeding 30 m, and up to 56.8 m (drill hole CV23-231) (see Table 1 and Table 2).

Further, multiple drill holes over this westerly extension have returned composited core-

length pegmatite intersections (i.e., sum of all pegmatite intervals within the hole) of over 90 m,

to a peak of approximately 144 m (CV23-223), including an unexpected and sizable (50.2 m)

continuous mineralized pegmatite intersection at depth in drill hole CV23-223. This intersection,

coupled with those from other drill holes completed over the western extension of CV5, indicates

that the principal pegmatite is bifurcating into two significantly thick spodumene pegmatites

lenses.

The CV5 Spodumene Pegmatite has now been traced by drilling to within 3.15 km of the CV13

Spodumene Pegmatite (Figure 4). Further, mineralogy and textures in drill core, coupled with

geophysics and geomorphology of the area as inferred from LiDAR and orthophoto data, suggests

that that the CV5 and CV13 spodumene pegmatites form one continuous pegmatite body

subsurface. However, a significant amount of drill testing remains to be completed along this

corridor to confirm this interpretation.

An infill drill hole at CV5, completed primarily for hydrogeological purposes (CV23-199),

returned the thickest interval of pegmatite (dominantly spodumene pegmatite) to date at the Project

(Figure 2) . This hole returned a near -continuous pegmatite interval of 178.2 m (core length) ,

including only 4.3 m of non-pegmatite internal dilution spread over four (4) discreet intervals. This

hole was completed as a vertical hole and therefore more oblique to the dip of the CV5 Spodumene

Pegmatite than is typical. True width of the pegmatite in this area of drill hole CV23 -199 is

estimated to approximate 125 m at a depth of 125 m. Assays are currently pending.

At the CV13 Spodumene Pegmatite, the summer -fall drilling has successfully delineated a

continuous pegmatite dyke that has now been traced between three (3) of the four (4) areas initially

drill tested in 2022 (Figure 5). The CV13 Spodumene Pegmatite trend extends for approximately

2.3 km as defined by outcrop and drilling in 2022 . The drill holes completed in 2023 along this

trend at CV13 have now confirmed a continuous, variably mineralized spodumene pegmatite

extending along at least 1.1 km of this trend and remains open.

This principal dyke at CV13 (the “upper” dyke) is geologically modelled to be shallowly dipping

to the north and remains open at depth and along strike. Core length pegmatite intersections of

the upper dyke range up to 21.9 m over the twenty (20) drill holes (~4,707 m) completed in 2023

through September 18 (Table 1). A “ lower”, more variably mineralized shallow and northerly

dipping pegmatite dyke present at CV13 has been tested in multiple drill holes in 2023; however,

remains of secondary focus at this time.

With the unprecedented season of wildfires expected to be behind us, the Company has continued

to ramp up its operations at the Project. A total of seven (7) drill rigs are currently active at site –

four (4) at CV5, two (2) at CV13, and one (1) at CV9. In support of continued exploration ramp

up, the KM-270 exploration camp is actively under construction with the primary accommodation

modules now on site and installation underway. Additionally, the conversion of the winter road

route to an all -season exploration road is continuing to advance. Both the camp and road are

anticipated to be operational mid fall with the Company planning on continuing drilling operations

into December. Following a much-deserved break for the holidays, activities will recommence in

mid January 2024, where the Company intends to ramp up to at least ten (10) drill rigs at site.

Due to the road closures in western parts of the Eeyou Istchee James Bay extending significantly

past the date in which the Company was able to re-commence drill operations at the Property, the

delivery of drill core samples to the laboratory was significantly delayed. However, core samples

for a large number of drill holes have now arrived at the laboratory with processing underway.

Results will be reported as received.

1 The CV5 mineral resource estimate (109.2 Mt at 1.42% Li2O and 160 ppm Ta2O5 inferred) is reported at

a cut-off grade of 0.40% Li2O with effective date of June 25, 2023 (through drill hole CV23-190). Mineral

resources are not mineral reserves as they do not have demonstrated economic viability.
