• A continuous 93 m interval of dominantly spodumene -bearing pegmatite in most

westerly drill hole completed to date at the CV5 Pegmatite – CV23-184 (assays pending).

• A continuous 139 m interval of dominantly spodumene-bearing pegmatite in final drill

hole of the 2023 winter program at the CV5 Pegmatite – CV23-190 (assays pending).

• Core sample assay results for 27 drill holes completed during the 2023 winter drill program

remain to be reported.

Blair Way, Company President and CEO, comments: “The drill bit continues to deliver for us as

confirmed by the strong grades and wide widths of mineralized pegmatite reported herein. With

our last hole providing the longest pegmatite intersection of the winter drill program (139 m), we

are certainly primed for continued success as we approach the beginning of our summer-fall drill

program, scheduled to commence later this month. With core sample assay s for numerous drill

holes remaining to be received, the Company ’s geological team is steadfast focused on final

validation of the CV5 Pegmatite’s geological model, inclusive of all drill holes completed to date,

ahead of an initial mineral resource estimate.”

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 east-central area proximal to the CV1 outcrop (Figure 2), and the recently defined westward

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

The drill holes targeting the east-central area of the CV5 Pegmatite were completed during the

winter program to take advantage of more practical and cost -effective ground access. These drill

holes were highly successful with mineralized pegmatite intervals of 122.6 m at 1.89% Li 2O,

including 8.1 m at 5.01% Li2O (CV23-138), 130.3 m at 1.56% Li2O, including 52.7 m at 2.45%

Li2O (CV23-132), 101.3 m at 1.44% Li 2O, including 28.1 m at 3.00% Li 2O (CV23-134), and

10.1 m at 2.42% Li2O and 4.0 m at 4.13% Li2O (CV23-130). These four (4) drill holes define a

new high-grade zone, which is interpreted to represent a continuous 200+ m extension westward

of the high- grade Nova Zone (see news release dated March 29, 2023 ). Drill holes CV23-181

(108 m of continuous pegmatite) and CV23-148 ( 95 m of continuous pegmatite) tested the

connection of the zones (i.e., the area between), with assays pending for both. However, based on

logged modal spodumene content, the high-grade Nova Zone is now interpreted to extend

continuously from at least drill hole CV23 -132 to CV23 -108, a distance of approximately

1,100 m.

Assay results for two (2) drill holes completed over the recently discovered westward extension of

the CV5 Pegmatite (see news released dated May 1, 2023 ) confirm strong lithium grades over

moderate to wide intervals in this area – 38.4 m at 1.19% Li2O, 7.8 m at 3.01% Li2O, and 8.8 m

at 1.29% Li2O (CV23-176), and 33.4 m at 0.87% Li2O and 12.8 m at 1.25% Li2O (CV23-161).

The CV5 Pegmatite remains open along strike westwardly in this area with the westernmost drill

hole completed to date (CV23- 184) returning a continuous 93 m interval of dominantly

spodumene-bearing pegmatite. Additionally, the final hole of the winter program (CV23-190),

also completed in this area , returned a continuous 139 m interval of dominantly spodumene -

bearing pegmatite – the widest pegmatite intercept of the 2023 winter program at the CV5

Pegmatite. Core sample analysis for both CV23- 184 and 190 have not yet been reported. These

drill holes were also completed in opposite directions across the CV5 Pegmatite body, further

attesting to the sizable blow-out (i.e., sizable width) of the pegmatite in this area (Figures 1 and 3).

The 2023 winter drill program recently concluded with a total of 89 drill holes and 32,367 m

completed – drill holes CV23 -105 through 190. Through the 2023 winter program, t he CV5

Pegmatite has now 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 (CV23-184 to CV23-125) and remains open along strike at both ends and to depth along

most of its length.

Due to the continuity of the pegmatite confirmed by the 2023 winter drill program, all holes

completed to date at the CV5 Pegmatite (through CV23-190) will be included in the forthcoming

mineral resource estimate. The Company is targeting a July 2023 announcement and is dependent

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

database and model validation.

The Company’s summer-fall drill exploration program is scheduled to re-commence in late May

at the CV5 and CV13 pegmatites. The summer-fall surface program is scheduled to begin in early

June and continue through late September.

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

remain to be reported for 27 drill holes completed during the winter program , with all drill core

samples having arrived at the analytical lab (SGS). Pegmatite intervals >2 m (core length) for all

drill holes completed during the winter program are presented in Table 2, and drill hole attributes

presented in Table 3. Tables 1, 2, and 3 will be posted to the Company’s website shortly. Select

core photos are presented in Figures 4 and 5.
