Patriot Announces Final Core Assay Results from its 2023 Winter

Drill Program, including 108.0 m at 2.44% Li2O, at the CV5

Pegmatite, Corvette Property, Quebec, Canada

July 10, 2023 – Vancouver, BC, Canada July 10, 2023 – Sydney, Australia

Highlights

• Additional high-grade intersections at the Nova Zone, which has been defined over a

strike length of at least 1.1 km.

o 108.0 m at 2.44% Li2O (195.5 m to 303.5 m), including 37.5 m at 3.58% Li2O,

or 16.0 m at 4.08% Li2O (CV23-181).

o 115.3 m at 1.81% Li 2O (175.0 m to 290.3 m), including 89.6 m at 2.20% Li2O

(CV23-177).

• Wide widths and strong grades in most westwardly drill hole completed to date at the

CV5 Pegmatite – 78.9 m at 1.00% Li2O, including 34.8 m at 1.40% Li2O (CV23-184).

• Wide widths and strong grades in final drill hole completed during the 2023 winter drill

program – 139.2 m at 1.26% Li2O, including 36.2 m at 1.74% Li2O (CV23-190).

• Wide widths and strong grades returned in one of the most eastwardly drill holes

completed to date at the CV5 Pegmatite, highlighting the strong potential of area – 36.0 m

at 1.36% Li2O, including 17.0 m at 2.31% Li2O (CV23-165).

• All core sample assay results for drill holes completed during the 2023 drill winter program

have now been reported.

• The Company is anticipating an announcement in a few weeks time for the initial mineral

resource estimate at CV5, which will include all drill holes completed through April 17,

2023 (i.e., the recently completed winter drill program).

Darren L. Smith, Patriot Vice President of Exploration, comments: “These final core assay results

from the recently completed winter program continue to outpace the industry norm. The CV5

Pegmatite has grown considerably over this program – from 2.2 km to 3.7 km , drill hole to drill

hole – with some of the highest grades reported to date at CV 5, including numerous significant

intervals over 5% Li 2O. As we wait for the wild fire situation in Quebec to abate , the team is

steadfast focused on delivering an initial mineral resource estimate for CV5 in the coming weeks,

which will include all drill holes from the 2023 winter program.”

Blair Way, Company President and CEO, comments: “ We are very pleased to have received t he

last batch of assay results from the winter drill program which means our imminent release of the

resource remains on track. I am confident that the upcoming maiden resource will demonstrate

the significance of the Corvette discovery to the evolving North American and European lithium

raw materials markets.”

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

(OTCQX: PMETF) (FSE: R9GA) is pleased to announce core assays for the final set of drill

holes completed as part of the 2023 winter drill program at its wholly owned Corvette Property

(the “Property”), located in the Eeyou Istchee James Bay region of Quebec . The winter phase of

the 2023 drill campaign was focused on the CV5 Pegmatite, located approximately 13.5 km south

of the regional and all-weather Trans-Taiga Road and powerline infrastructure.

Core assays, for the drill holes reported herein (Figure 1), cover the CV5 Pegmatite’s recently

defined eastward extension (see news releases dated February 5 and March 23, 2023) (Figure 2),

the high-grade Nova Zone (see news release dated May 16, 2023 ) (Figure 2), and the recently

defined westward extension (see news release dated May 1, 2023) (Figure 3).

Drill hole CV23-181 and 177 targeted further delineation of the Nova Zone with both returning

wide and high- grade intercepts – 108.0 m at 2.44 % Li2O, including 37.5 m at 3.58% Li 2O or

16.0 m at 4.08% Li 2O (CV22-181), and 115.3 m at 1.81% Li 2O, including 89.6 m at 2.20%

Li2O (CV23-177). The high-grade Nova Zone has been traced over a strike length of at

least 1.1 km – from drill holes CV23- 132 to 108 (Figures 1 and 2) and includes multiple drill

intersections of 5+ m at >5% Li2O, demonstrating the high- grade tenure of this sub- set of the

Corvette discovery.

As the Company works towards extension of the Corvette discovery , core assay results for the

most westwardly drill hole completed to date at the CV5 Pegmatite – CV23-184 – demonstrates

high-grades and wide widths persist in this direction (78.9 m at 1.00% Li2O, including 34.8 m at

1.40% Li2O), with mineralization remaining open. The Company intends to continue step-out

drilling along strike of CV23- 184 during the summer-fall drill program (Figure 3). Additionally,

drill hole CV23-190, the final hole of the 2023 winter program , also completed over the western

areas of CV5, returned strong grades over wide widths – 139.2 m at 1.26% Li2O, including 18.1

m at 2.02% Li 2O and 36.2 m at 1.74% Li 2O. This drill hole was completed in the opposite

direction (northerly) to the normal drill hole orientation (southerly) at CV5 and demonstrates the

near-surface bulbous nature of the pegmatite in this area, where it is interpreted to exceed 100 m

true thickness.

Assay results to date over the far eastern portions of CV5 have returned variable grades and widths

of lithium mineralized pegmatite (see news release dated June 14, 2023). These include 51.2 m at

0.59% Li2O, including 10.1 m at 0.87% Li 2O and 9.3 m at 0.91% Li 2O (CV23-154), and 27.5 m

at 0.40% Li 2O, including 3.2 m at 2.22% Li 2O (CV23-156). However, results of drill hole

CV23-165, as reported herein (36.0 m at 1.36% Li2O, including 17.0 m at 2.31% Li2O), are very

significant and demonstrate the common nature of lithium pegmatites, where high grades may be

immediately proximal to low to moderate grades. Further, this drill hole (CV23-165) returned six

(6) samples greater than 4% Li 2O, and three (3) samples greater than 5% Li 2O, including

an interval of 2.2 m at 5.02% Li2O. These grades are on par with those typically confined to the

Nova Zone and outline the considerable potential in this eastward area.

Drill hole CV23-165 was completed at the very eastern margins of the CV5 Pegmatite drill ed to

date and highlight the potential for wide widths at strong grade to continue in this direction, where

the pegmatite remains open up-dip, down-dip, and along strike eastwardly (Figure 2).

Through the 2023 winter drill program , the CV5 Pegmatite has been traced continuously by

drilling (at approximately 50 to 150 m spacing) as a principally continuous spodumene -

mineralized pegmatite body over a lateral distance of at least 3.7 km and remains open along

strike at both ends and to depth along a large portion of its length. This marks a 1.5 km extension

of the known mineralized pegmatite along strike since the end of 2022 (2.2 km), and 2.9 km since

the end of 2021 (0.8 km). For added perspective, this growth in strike length since the initial drill

program in 2021 is presented in Figure 4.

As previously announced, the Company is advancing towards an initial mineral resource estimate

for the CV5 Pegmatite . All core sample assays have now been received from the lab with the

drilling dataset undergoing final validation and geological model on the final revision. The next

steps in the process include geostatistics on the validated database followed by creation of the

block model and interpolation of the lithium and tantalum grades, resource classification,

determination of an appropriate cut-off grade and pit parameters, and finally constraining the block

model with a pit to determine the official mineral resource estimate numbers. At this time , the

Company anticipates an announcement on the mineral resource estimate in a few weeks time.

Core sample assay results for drill holes reported herein are presented in Table 1 . Drill hole

locations are available from the Company’s website as well as the news release dated May 16,

2023. Select core photos are presented in Figures 5, 6, a nd 7.
