• Core sample assay results for 12 drill holes completed during the 2023 winter drill program

remain to be reported.

• The Company remains on target for a July 2023 announcement 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).

Blair Way, Company President and CEO, comments: “ The final assay results for the recently

completed winter drill hole program continue to come in, with 12 holes now remaining to be

reported. Results continue to impress as we position for the release of our initial mineral resource

estimate at CV5.”

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 next series of drill

holes completed as part of the 2023 winter drill program, which recently concluded 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 -148 targeted the Nova Zone and returned a wide and high- grade intercept of

95.3 m at 1.62% Li2O, including 47.6 m at 2.09% Li2O or 4.1 m at 4.44% Li2O. The high-grade

result affirms the interpretation that the Nova Zone extends continuously over a strike length of at

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

Strong grades and widths were returned in drilling over the recently defined westward extension

(Figure 3) , highlighted by drill hole CV23 -160A, which returned 127.7 m at 1.78% Li 2O,

including 50.1 m at 2.43% Li2O. Other drill holes in this area, with assays reported herein, include

CV23-172 ( 13.2 m at 1.14% Li 2O, and 15.7 m at 0.94% Li 2O), CV23-182 ( 14.8 m at

1.06% Li2O), and CV23-187 (14.1 m at 1.19% Li2O). Additionally, drill hole CV23-174, located

proximal to the westward extension, returned a strong intercept of 44.2 m at 0.99% Li 2O,

including 15.3 m at 2.58% Li2O.

Drill core sample assays for two (2) holes remain to be reported over the westward extension area

of the CV5 Pegmatite (Figure 1). This includes a continuous 93 m interval of dominantly

spodumene-bearing pegmatite in the most westerly drill hole completed through the end of the

winter program (CV23-184), and a continuous 139 m interval of dominantly spodumene -bearing

pegmatite in the final drill hole of the 2023 winter program (CV23-190).

Assay results for holes reported herein over the far eastern portion of CV5 (Figure 2) , as is

currently defined, returned variable grades and widths of lithium mineralized pegmatite. Results

include 51.2 m at 0.59% Li 2O, 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). Internal

fractionation commonly leads to lower-grade pegmatite being immediately adjacent to higher -

grade pegmatite. Considering the wide and continuous widths of pegmatite in these holes (CV23-

154 and 156), at 49.9 m and 27.5 m, respectively, the grades returned are very encouraging with

respect to the potential for additional and proximal higher-grade zones to be present. The pegmatite

in this area remains open up-dip, down-dip, and along strike eastwardly.

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

both ends and to depth along most of its length.

The Company remains on target for a July 2023 announcement 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). The timing of the announcement remains dependent on

timely receipt of the final outstanding core sample assays from the lab oratory, as well as final

database and model validation.

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

remain to be reported for twelve (12) drill holes completed during the winter program , with all

drill core samples having arrived at the analytical lab (SGS). Drill holes locations are available

from the Company’s website as well as news release dated May 16, 2023. Select core photos are

presented in Figures 4 and 5.

Quality Assurance / Quality Control (QAQC)

A Quality Assurance / Quality Control protocol following industry best practices was incorporated

into the program and included systematic insertion of quartz blanks and certified reference

materials into sample batches, as well as collection of quarter -core duplicates, at a rate of

approximately 5%. Additionally, analysis of pulp -split and coarse- split sample duplicates w ere

completed to assess analytical precision at different stages of the laboratory preparation process,

and external (secondary) laboratory pulp- split duplicates were prepared at the primary lab for

subsequent check analysis and validation.

All core samples collected were shipped to SGS Canada’s laboratory in Val-d’Or, QC, for standard

sample preparation (code PRP89) which includes drying at 105°C, crush to 75% passing 2 mm,

riffle split 250 g, and pulverize 85% passing 75 microns. The pulps were shipped by air to SGS

Canada’s laboratory in Burnaby, BC, where the samples were homogenized and subsequently

analyzed for multi-element (including Li and Ta) using sodium peroxide fusion with ICP-AES/MS

finish (codes GE_ICP91A50 and GE_IMS91A50).

About the CV Lithium Trend

The CV Lithium Trend is an emerging spodumene pegmatite district discovered by the Company

in 2017 and spans more than 25- km across the Corvette Property. The core area includes an

approximate 3.7 km long spodumene pegmatite (the ‘C V5 Pegmatite’) and multiple proximal

secondary spodumene pegmatite lenses.

To date, six (6) distinct clusters of lithium pegmatite have been discovered across the Corvette

Property – CV5 Pegmatite and associated lenses, CV4, CV8 -12, CV9, CV10, and CV13. G iven

the proximity of some pegmatite outcrops to each other, as well as the shallow till cover in the

area, it is probable that some of the outcrops may reflect a discontinuous surface exposure of a

single, larger pegmatite ‘outcrop’ subsurface. Further, t he high number of well -mineralized

pegmatites along the trend indicate a strong potential for a series of relatively closely

spaced/stacked, sub-parallel, and sizable spodumene -bearing pegmatite bodies, with significant

lateral and depth extent, to be present.
