Patriot Drills 31.2 m at 3.35% Li 2O at CV13 including 4.7 m at

5.37% Li2O, Significantly Expanding the High-Grade Vega Zone

December 11, 2024 – Vancouver, BC, Canada December 12, 2024 – Sydney, Australia

Highlights

• Recent drilling significantly expands the high-grade Vega Zone at CV13:

o 31.2 m at 3.35% Li2O, including 4.7 m at 5.37% Li2O (CV24-747).

o 31.8 m at 2.07% Li2O, including 11.7 m at 3.47% Li2O (CV24-773).

▪ Includes a 0.9 m sample at 7.11% Li 2O, the highest-grade core sample

collected from the Property to date.

o 35.7 m at 1.65% Li2O, including 28.3 m at 2.05% Li2O (CV24-582).

o 33.0 m at 2.02% Li2O, including 4.6 m at 4.19% Li2O (CV24-754).

o 29.2 m at 2.05% Li2O, including 14.3 m at 3.09% Li2O (CV24-761).

• Vega Zone remains open in multiple directions.

• The Vega Zone is coincident with a n interpreted structural corridor extending

for approximately 3.3 km along strike to the CV12 Spodumene Pegmatite – a

highly prospective corridor that remains to be drill tested.

o This association significantly enhances the prospectivity between CV13 and CV12.

• Mineralization continues to be characterized by very large spodumene crystals.

• Results for all drill holes completed at the CV13 Spodumene Pegmatite during the 2024

winter program are reported in this announcement – 33 holes totaling 9,950 m – with all

holes completed outside the 2024 Mineral Resource Estimate or at its margin.

Darren L. Smith, Patriot Executive and Vice President of Exploration, comments: “The summer-fall

drilling at CV13 achieved its key objectives of significantly expanding the high-grade Vega Zone as well as

identifying some potential primary controls on its emplacement. The interpreted coincident structure

suggests it may be a primary control on mineralization and extends for approximately 3.3 km towards the

CV12 Spodumene Pegmatite. This discovery has increased the prospectivity of this corridor considerably

and will be a key area of focus in follow-up drilling in 2025.

“The mineralization at the Vega Zone continues to show many similarities to that of the high-grade Nova

Zone at CV5. The intensity of the spodumene mineralization – with samples commonly exceeding 2% Li2O

and including two core samples now over 7% Li2O – is nothing less than remarkable and clearly reinforces

the world-class nature of the lithium pegmatites at Shaakichiuwaanaan,” Mr. Smith added.

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

(OTCQX: PMETF) (FSE: R9GA ) is pleased to announce core assay results for all holes

completed at the CV13 Spodumene Pegmatite, which forms part of the Company’s wholly owned

Shaakichiuwaanaan Property (the “Property” or “Project”), located in the Eeyou Istchee James Bay

region of Quebec, during the 2024 summer-fall drill program.

The Property hosts a consolidated (CV5 & CV13) Mineral Resource Estimate1 (“MRE”) of 80.1 Mt

at 1.44% Li2O Indicated and 62.5 Mt at 1.31% Li2O Inferred, with the CV13 Pegmatite accounting

for approximately 15% of the contained overall lithium content. The CV13 Spodumene Pegmatite

is located within 3 km of the CV5 Spodumene Pegmatite, which is accessible year -round by all -

season road and is situated approximately 14 km from a major hydroelectric powerline corridor.

The summer-fall drill program at the CV13 Spodumene Pegmatite targeted the high -grade Vega

Zone, located along its eastern flank. The objectives were to expand this high-grade zone as well

as to identify some primary controls on its emplacement. A total of 33 NQ size drill holes

(9,950 m) were completed. Highlights are listed below and expanded upon in Figure 1:

• 31.2 m at 3.35% Li2O, including 4.7 m at 5.37% Li2O (CV24-747).

• 31.8 m at 2.07% Li2O, including 11.7 m at 3.47% Li2O (CV24-773).

• 35.7 m at 1.65% Li2O, including 28.3 m at 2.05% Li2O (CV24-582).

• 33.0 m at 2.02% Li2O, including 4.6 m at 4.19% Li2O (CV24-754).

• 29.2 m at 2.05% Li2O, including 14.3 m at 3.09% Li2O (CV24-761).

The program also returned the highest-grade individual core sample collected to date from the

entire Shaakichiuwaanaan Property – 0.9 m at 7.11% Li2O in drill hole CV24-773 (Figure 2). This

is the second core sample collected at the P roperty (both at CV13) to exceed 7% Li 2O. To put

this further into perspective, the targeted grade of spodumene concentrate post concentration in

a processing facility – the base case marketable product in the industry – is 5.5% Li2O.

Additionally, t he mineralization at Vega continues to be characterized by very large

spodumene crystals of decimetre to metre scale (Figure 2 and Figure 3). Based on the large

spodumene crystal sizes and prior beneficiation testwork on the CV13 Pegmatite, a dense media

separation (“DMS”) only flowsheet is considered probable (see news release dated July 4, 2023).

All mineralised pegmatite intersections from the summer-fall drill program at CV13

are located outside of the MRE’s block model , or at its margins, and therefore

represent a significant expansion of the Vega Zone.

This expansion of the Vega Zone highlights considerable potential for continued high-grade

resource growth at CV13 – where the current MRE of 1.5 Mt at 1.62% Li2O Indicated and 19.1 Mt

at 1.46% Li2O Inferred forms part of the larger Shaakichiuwaanaan MRE 1 (see news release dated

August 5, 2024).

1 Shaakichiuwaanaan (CV5 & CV13) Mineral Resource Estimate (80.1 Mt at 1.44% Li 2O and 163 ppm Ta2O5 Indicated, and 62.5 Mt

at 1.31% Li2O and 147 ppm Ta 2O5 ppm Inferred) is reported at a cut -off grade of 0.40% Li 2O (open-pit), 0.60% Li2O (underground

CV5), and 0.80% Li 2O (underground CV13) with an Effective Date of August 21, 2024 (through drill hole CV24 -526). Mineral

Resources are not Mineral Reserves as they do not have demonstrated economic viability.

The Vega Zone remains open in multiple directions and covers an area of at least ~0.7 km

x 0.4 km with a true thickness of <10 m to 30+ m, hosted within a wider mineralized pegmatite

body. Geological modelling (Figure 4) indicates the Vega Zone to be relatively flat-lying to shallow

dipping and near-surface (starting at ~100 m vertical depth from surface) . The CV13 Spodumene

Pegmatite, which hosts the Vega Zone, has now been traced over a strike length of ~2.5 km, down-

dip over more than 500 m and remains open in multiple directions.

In addition to the significant expansion of the Vega Zone, the program was successful in

identifying an interpreted coincident structure, which may be a primary control on

the high-grade mineralization (Figure 5 and Figure 6). This structural corridor (referred to in

this announcement as the “Vega Structural Corridor”) is supported from local and regional

magnetic data (expressed as a linear feature) as well as structural observations in drill core and is

interpreted to extend at least 3.3 km north-west along geological trend to the CV12

Spodumene Pegmatite.

Apart from the currently defined extent of the Vega Zone and a single shallow drill hole at CV12,

this corridor remains to be drill tested and is , therefore, considered highly prospective.

Further, a second structural corridor that is interpreted to extend north-west for

approximately 1.9 km from CV13 to the CV8 Spodumene Pegmatite also remains to

be drill tested and is considered to be highly prospective.

Figure 6: Highly prospective interpreted structural corridor coincident with the high-grade Vega Zone at

extend ~3.3 km to the CV12 Spodumene Pegmatite and remains to be drill tested.
