• Core assay results for 98 drill holes (31,513 m) – all from CV5 – are reported in this

announcement, concluding the reporting of all 431 holes (128,052 m) completed in 2024.

• This final batch of assays completes the core analytical dataset required for the delivery of

the Feasibility Study and maiden Ore Reserve Estimate for the CV5 Spodumene

Pegmatite, which is targeted for Q3 -2025. All resource, geotechnical,

geomechanical, and hydrogeological drilling required to support the pending

Feasibility Study on CV5 is now complete.

• The Company has now completed 793 drill holes ( 233,884 m) at the Shaakichiuwaanaan

Property to deliver the largest hard rock lithium resource in the Americas in under 3 years.

Darren L. Smith, Patriot Executive and Vice President of Exploration, comments: “The fall 2024 in-

fill drill program at the CV5 Pegmatite wrapped up on a very strong note, delivering more than 10 well-

mineralized 100+ m i ntercepts. The completion of the in -fill program marks a key milestone towards

upgrading the Mineral Resource to higher confidence (from Inferred to Indicated) , and we were able to

achieve this on schedule and under budget.”

“The team is now advancing the geological and block models in coordination with our independent

consultants as we work towards the next Mineral Resource update , which in turn will underpin the

upcoming Feasibility Study and maiden Ore Reserve for the CV5 Pegmatite – which remain on schedule

for Q3-2025,” added Mr. Smith.

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

(OTCQX: PMETF) (FSE: R9GA) is pleased to announce the final batch of results from its

extensive summer-fall 2024 in-fill drill program at the CV5 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.

The Shaakichiuwaanaan Property hosts a consolidated Mineral Resource Estimate1 (“MRE”) of

80.1 Mt at 1.44% Li2O Indicated and 62.5 Mt at 1.31% Li2O Inferred. The CV5 Spodumene

Pegmatite, which forms the bulk of the MRE, is accessible year-round by all -season road and is

situated approximately 14 km from a major hydroelectric powerline corridor.

Core assay results for 98 holes (31,513 m) are reported in this announcement (Figure 1, Table 1,

Table 2), concluding the reporting of all 431 holes (128,052 m) completed during the 2024 drill

campaign at the Property. The holes reported in this announcement focused on in-fill drilling at

the CV5 Deposit to support an MRE update targeting conversion of Mineral Resources from the

Inferred category to the higher confidence Indicated category, which will in turn underpin a maiden

Ore Reserve Estimate.

The drill h oles reported tested nearly the entire 4.6 km strike length currently defined at CV5,

which remains open at both ends and at depth, along a significant portion of its length. The results

continue to demonstrate that wide and well -mineralized pegmatite, with consistently large

spodumene crystals, is present along the entire strike length of the deposit (Figure 1, Figure 2,

Figure 3, and Figure 4).

With the delivery of these results , all resource, geotechnical, geomechanical, and

hydrogeological drill holes required to support the pending Feasibility Study on CV5

are now complete. These drill holes targeted areas encompassing the anticipated supporting

development infrastructure (process plant, camp, stockpiles, waste rock and tailings management

facilities, etc.), as well open-pit and underground development areas. The data collected will be

used to establish a maiden Ore Reserve, infrastructure foundation and build parameters, rock

mechanics domain parameters, and hydrogeological models to support the overall mine design for

the pending Feasibility Study.

1 Shaakichiuwaanaan (CV5 & CV13) Mineral Resource Estimate (80.1 Mt at 1.44% Li2O and 163 ppm Ta2O5 Indicated, and 62.5 Mt

at 1.31% Li2O and 147 ppm Ta2O5 ppm Inferred) is reported at a cut-off grade of 0.40% Li2O (open-pit), 0.60% Li2O (underground

CV5), an d 0.80% Li2O (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.

Figure 1: Drill holes completed through 2024 at CV5 with result highlights in this announcement.

Collectively, over the 2024 drill campaign a total of 431 holes (128,052 m) were completed across

the CV5 and CV13 pegmatites, as well as areas of proposed infrastructure in support of future

development. This includes step-out and in-fill holes, as well as geotechnical, hydrogeological, and

geomechanical holes.

Since the “discovery hole”, CF21-001 – the first hole to test the CV5 Pegmatite surface exposures

at depth – was completed in fall 2021, a total of 793 holes totalling 233,884 m have been completed

at Shaakichiuwaanaan focused on exploration and development of lithium pegmatite.

This drilling has delineated the largest hard rock lithium resource in the Americas –

Shaakichiuwaanaan (comprising the CV5 & CV13 pegmatites).

The collective drill dataset s will underpin an updated and higher -confidence MRE for the

Shaakichiuwaanaan Project (CV5 & CV13 pegmatites), as well as an expected maiden Ore Reserve

for the CV5 Spodumene Pegmatite, which will be declared upon completion of the Feasibility

Study, which is targeted for delivery in Q3-2025.
