• The focus of the 2024 winter drilling at CV5 was to support an upgrade in mineral resource

confidence, from the inferred category to the indicated category , targeting release in Q3

2024 inclusive of a maiden CV13 resource.

• Multiple holes remain to be reported targeting the newly discovered high-grade zone at

CV13, with the Company to report the assay results as soon as they are received in the

coming weeks.

• 38,887 m (111 holes) remain to be reported from the 2024 winter drill program – 27,611

m (67 holes) at CV5, and 11,276 m (44 holes) at CV13.

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

(OTCQX: PMETF) (FSE: R9GA) is pleased to announce the next batch of core assay results

for drill holes completed in 2024 at the CV5 Spodumene Pegmatite. The Corvette Property (the

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

Bay region of Quebec. The CV5 Spodumene Pegmatite, with a maiden mineral resource estimate

(“MRE”) of 109.2 Mt at 1.42% Li 2O inferred 1, is situated approximately 13.5 km south of the

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

Darren L. Smith, Vice President of Exploration for the Company comments, “Another round of CV5

core assays from our infill program and it continues to deliver to expectations. Coupled with the new high-

grade discovery at CV13, the 2024 winter program’s results continue to demonstrate the quality and scale

on show at Corvette.”

“It’s been a huge effort from the team to progress what was a very large-scale drill program over the last

6-8 months. Through their efforts, all drilling up until our recent seasonal break, including the previously

highlighted CV13 high-grade discovery, will make it into the upcoming resource update”, added Mr. Smith.

Figure 1: Drill holes completed at the CV5 Spodumene Pegmatite through April 2024.

Core assay results for 20 drill holes, completed during the recently completed 2024 winter drill

program at the CV5 Spodumene Pegmatite, are reported herein (Figure 1). Highlights include:

• 122.5 m at 1.42% Li2O, including 35.8 m at 2.15% Li2O (CV24-405).

• 71.4 m at 1.57% Li2O, including 14.2 m at 3.15% Li2O (CV24-435).

• 68.7 m at 1.56% Li2O and 22.5 m at 1.04% Li2O (CV24-414).

• 74.9 m at 1.28% Li2O, including 28.1 m at 2.28% Li2O (CV24-423A).

• 53.0 m at 1.22% Li2O, including 25.0 m at 1.65% Li2O (CV24-450).

The results of the drill holes reported herein cover a significant strike length of the CV5

Spodumene Pegmatite . The holes were completed at varying orientations targeting specific

sections of the pegmatite body at depth over a significant strike length . The results continue to

demonstrate robust thicknesses and lithium grade of the spodumene pegmatite body(s) that define

CV5 (Figure 2 and Figure 3).

The 2024 winter drill program at CV5 focused on resource infill and covered ~3.9 km of the total

4.6 km pegmatite strike length defined to date . The primary objective of the infill drilling is to

improve the confidence of the geological model at CV5 to support an upgrade of mineral resources

from the inferred category to the indicated category. This includes the delineation of a coherent

body of indicated mineral resources to support advanced development and pending economic

studies at CV5.

The 2024 winter drill program (now complete), totaled 62,518 m (166 holes) , including

50,961 m (121 holes) at CV5, and 11,557 m (45 holes) at CV13, of which 38,886.6 m (111 holes)

remain to be reported – 27,611 m (67 holes) at CV5, and 11,276 m (44 holes) at CV13. This

includes multiple holes that remain to be reported targeting the newly discovered high-grade zone

at CV13.

An updated MRE for the Corvette Project, incorporating drilling through April 2024, is scheduled

for Q3 2024. This MRE update will include both the CV5 and CV13 spodumene pegmatites and a

total anticipated metreage of 134,129 m (369 holes) and 29,121 m (133 holes), respectively.

Core sample assays for drill hole s reported herein from the CV 5 Spodumene Pegmatite are

presented in Table 1 for all pegmatite intersections >2 m. Drill hole locations and attributes are

presented in Table 2.

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. Largest lithium pegmatite resource in the

Americas based on contained LCE.

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 at a rate of approximately 5%. Addit ionally, analysis of pulp -split

sample duplicates was completed to assess analytical precision, 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 Radisson, QC, for sample

preparation (code PRP90 special) which includes drying at 105°C, crush to 90% 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 anal yzed 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 is interpreted to span more than 50 kilometres across the Corvette Property. The

core area includes the approximate 4.6 km long CV5 Spodumene Pegmatite, which hosts a maiden

mineral resource estimate of 109.2 Mt at 1.42% Li2O inferred1.

To date, eight (8) distinct clusters of lithium pegmatite have been discovered across the Corvette

Property – CV4, CV5, CV8, CV9, CV10, CV12, CV13, and the recently discovered CV14. Given

the proximity of some pegmatite outcrops to each other, as well as t he 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.
