Significant Mineral Resource Upgrade at Shaakichiuwaanaan

Lithium Project to Underpin Impending PEA

August 5, 2024 – Vancouver, BC, Canada August 6, 2024 – Sydney, Australia

HIGHLIGHTS

• The Mineral Resource Estimate for the Shaakichiuwaanaan Lithium Project (formerly

known as Corvette) reaffirmed as the largest lithium pegmatite M ineral Resource

in the Americas and the 8th largest globally:

o Consolidated Mineral Resource statement (CV5 & CV13 spodumene pegmatites)

o 80.1 Mt at 1.44% Li2O and 163 ppm Ta2O5 Indicated, and

o 62.5 Mt at 1.31% Li2O and 147 ppm Ta2O5, Inferred.

• The Company remains on track to provide the market with a Preliminary Economic

Assessment for the CV5 Spodumene Pegmatite by the end of September quarter based on

the Mineral Resource Estimate announced herein.

• Shaakichiuwaanaan Mineral Resource includes 6.9 km of collective strike length now

confirmed to host continuous spodumene pegmatite Mineral Resources (4.6 km

at CV5 and 2.3 km at CV13).

• Significant growth potential – both the CV5 and CV13 spodumene pegmatites remain

open along strike at both ends, and to depth.

• Cut-off grade sensitivity analysis defines significant tonnage at very high grade ,

primarily reflecting the Nova and Vega zone discoveries at CV5 and CV13, respectively.

• Mineral Resource Estimate includes only the CV5 and CV13 s podumene

pegmatites. It does not include any of the other known spodumene pegmatite clusters

on the Property – CV4, CV8, CV9, CV10, CV12, and CV14.

• The Company intends to aggressively advance the remaining infill drilling at CV5 to

underpin a maiden ore reserve and Feasibility Study scheduled for Q3-2025.

Darren L. Smith, Vice President of Exploration, comments: “This is a significant update to our Mineral

Resource Estimate at Shaakichiuwaanaan, which now includes both the CV5 and CV13 spodumene

pegmatites as well as a significant amount of resources now classified as Indicated. This resource update

objectively reaffirms the Tier 1 nature of the spodumene pegmatites that define the Shaakichiuwaanaan

Project. Further, with both the CV5 and CV13 pegmatites remaining open, as well as multiple spodumene

pegmatite clusters on the Property still to be drill tested, significant potential for further resource growth is

evident.”

“Exploration success in this industry is never less than a team effort . In this regard, I would like to

acknowledge the dedication, work ethic, and contributions from the exploration and development teams,

our supporting service providers and consultants, and finally our Chisasibi community workers who have

all helped advance Shaakichiuwaanaan through to this key milestone on the path to potential production,”

added Mr. Smith.

Ken Bri nsden, President, CEO, and Managing Director , comments: “This is a significant

accomplishment for our team and a major milestone for the Company as we cement the

Shaakichiuwaanaan Lithium Project’s position as one of the most important new hard rock lithium assets

globally.”

“The delivery of a substantial maiden Indicated Resource of over 80 million tonnes is a major milestone

which will underpin development studies, while the continued growth of the overall resource – in conjunction

with the Exploration Target announced separately today – highlights the Tier-1 scale of the mineral system

and the enormous potential for further growth. I am immensely proud of our team members and

consultants who continue to put a significant focus on safety and quality deliverables as we move forward

through the various phases of development”.

“As we advance towards a Preliminary Economic Assessment in the near-term for the Shaakichiuwaanaan

Project, and further towards a Feasibility Study scheduled for completion Q3 2025, the Company is firmly

positioned as a leading candidate to provide long -term spodumene supply to the North American and

European markets,” added Mr. Brinsden.

PATRIOT BATTERY METALS INC. (THE “COMPANY” OR “PATRIOT”) (TSX: PMET) (ASX:

PMT) (OTCQX: PMETF) (FSE: R9GA) is pleased to announce an updated consolidated

Mineral Resource Estimate (“MRE” or “Consolidated MRE”) for the CV5 and CV13 s podumene

pegmatites at its 100% -owned Shaakichiuwaanaan Property (the “Property” or “Project” ) –

formerly known as Corvette – located in the Eeyou Istchee James Bay region of Quebec. The CV5

Spodumene Pegmatite is situated approximately 13.5 km south of the regional and all ‑weather

Trans-Taiga Road and powerline infrastructure corridor, and is accessible year-round by all-season

road. The CV13 Spodumene Pegmatite is located approximately 3 km west-southwest of CV5.

The updated Consolidated MRE for the Shaakichiuwaanaan Project includes both the CV5 and

CV13 spodumene pegmatites for a total of 80.1 Mt at 1.44% Li2O Indicated and 62.5 Mt at

1.31% Li2O Inferred, for 4.88 Mt contained lithium carbonate equivalent (“LCE”) (Table 1, Figure

1, and Figure 2). Presented by resource location/name, this MRE includes 78.6 Mt at 1.43% Li2O

Indicated and 43.3 Mt at 1. 25% Li2O Inferred at CV5, and 1.5 Mt at 1.62% Li 2O Indicated and

19.1 Mt at 1.46% Li 2O Inferred at CV13. The cut-off grade is variable depending on the mining

method and pegmatite (see footnotes in Table 1 for details). Mineral Resources are not Mineral

Reserves as they do not have demonstrated economic viability

The Consolidated MRE for the Shaakichiuwaanaan Project, including that of the CV5 Pegmatite on

its own, reaffirms it – by a wide margin – as the largest lithium pegmatite Mineral Resource

in the Americas and 8 th largest globally (Figure 1, Figure 2, Appendix 2, and Appendix 3).

These metrics and context firmly reaffirm and entrench the Project as a Tier 1, world

class lithium pegmatite asset.

A primary objective of the drilling completed subsequent to the July 2023 MRE, was to target a

significant upgrade from Inferred resources to Indicated resources, which correlates to a more

robust Mineral Resource with higher confidence classification. As a result, in addition to the overall

size of the MRE increasing compared to the maiden MRE (see news release dated July 30, 2023 ),

a significant amount of the resource has now been classified as Indicated (80.1 Mt at

1.44% Li2O) compared to no Indicated resources being classified in the maiden MRE.

The Consolidated MRE statement for the Shaakichiuwaanaan Project, presented in Table 1,

includes only the CV5 and CV13 spodumene pegmatite s, which remain open at both ends along

strike and to depth along most of their length. Therefore, this Consolidated MRE does not include

any of the other known spodumene pegmatite clusters on the Property – CV4, CV8, CV9, CV10,

CV12, and CV14 (Figure 3 and Figure 33). Collectively, this highlights a considerable potential

for resource growth through continued drill exploration at the Property.

The Mineral Resource statement and relevant disclosure, sensitivity analysis, peer comparison,

geological and block model views, and cross -sections are presented in the following figures and

tables. A detailed overview of the MRE and Project is presented in the following sections in

accordance with ASX Listing Rule 5.8.

• Mineral Resources were prepared in accordance with National Instrument 43 -101 – Standards for Disclosure of

Mineral Projects (“NI 43-101”) and the CIM Definition Standards (2014). Mineral Resources that are not M ineral

Reserves do not have demonstrated economic viability. This estimate of Mineral Resources may be materially

affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, economic, or other relevant

issues.

• The independent Competent Person (CP), as defined under JORC, and Qualified Person (QP), as defined by

NI 43-101 for this estimate is Todd McCracken, P.Geo., Director – Mining & Geology – Central Canada, BBA

Engineering Ltd. The Effective Date of the estimate is June 27, 2024 (through drill hole CV24-526).

• Estimation was completed using a combination of ordinary kriging and inverse distance squared (ID2) in Leapfrog

Edge software with dynamic anisotropy search ellipse on specific domains.

• Drill hole composites at 1 m in length. Block size is 10 m x 5 m x 5 m with sub-blocking.

• Both underground and open-pit conceptual mining shapes were applied as constraints to demonstrate reasonable

prospects for eventual economic extraction. Cut-off grades for open-pit constrained resources are 0.40% Li2O for

both CV5 and CV13, and for underground constrained resources are 0.60% Li 2O for CV5 and 0.80% Li 2O for

CV13. Open-pit and underground Mineral Resource constraints are based on a spodumene concentrate price of

US$1,500/tonne (6% basis FOB Bécancour) and an exchange rate of 0.76 USD/CAD.

• Rounding may result in apparent summation differences between tonnes, grade, and contained metal content.

• Tonnage and grade measurements are in metric units.

• Conversion factors used: Li2O = Li x 2.153; LCE (i.e., Li2CO3) = Li2O x 2.473, Ta2O5 = Ta x 1.221.

• Densities for pegmatite blocks (both CV5 & CV13) were estimated using a linear regression function (SG = 0.0688x

Li2O% + 2.625) derived from the specific gravity (“SG”) field measurements and Li2O grade. Non-pegmatite blocks

were assigned a fixed SG based on the field measurement median value of their respective lithology.

Figure 1: MRE tonnage vs grade chart highlighting Shaakichiuwaanaan as the largest lithium

pegmatite Mineral Resource in the Americas. See Appendix 2 and 3 for further details.

Figure 2: MRE tonnage vs grade chart highlighting Shaakichiuwaanaan as the 8 th largest lithium

pegmatite Mineral Resource in the world. See Appendix 2 and 3 for further details.

The Shaakichiuwaanaan MRE covers a collective strike length of approximately 6.9 km, drill hole

to drill hole (4.6 km at CV5, and 2.3 km at CV13). Further, t he CV5 a nd CV13 spodumene

pegmatites are situated along the same geological trend, separated by approximately 2.9 km, and

therefore this corridor is considered highly prospective for lithium pegmatite ( Figure 3). This

corridor remains to be drill tested; however, current interpretation of the collective dataset over

the trend indicates a reasonable potential for connectivity of the pegmatite body(s). As such, given

the similar mineralogy, geochemistry, host geological and structural trend, and close proximity to

each other (< 3 km) , the MREs for the CV5 and CV13 pegmatites have been presented as a

consolidated MRE for the Project ( Table 1). The MRE is further detailed below with respect to

conceptual mining constraint shapes by resource location/name (Table 2).

The Shaakichiuwaanaan database includes 537 diamond drill holes completed over the 2021, 2022,

2023, and 2024 (through the end of April – drill hole CV24-526) programs, for a collective total

of 169,526 m, as well as 88 outcrop channels totalling 520 m. The MRE is supported by 344 holes

(129,673 m) and 11 outcrop channels (63 m) at CV5, and 132 holes (29,059 m) and 54 outcrop

channels (340 m) at CV13.

SENSITIVITY ANALYSIS

The sensitivity analysis for the Shaakichiuwaanaan MRE (Table 3 and Figure 4) is presented as the

sum of the open-pit and underground constrained and classified resources at the same cut-off. The

sensitivity analysis by cut-off grade (“COG”) defines significant tonnage at very high-

grade, primarily reflecting the Nova Zone at CV5 and Vega Zone at CV13.

• At a 1.5% Li 2O COG for the CV5 Pegmatite, there is a total of 30.4 Mt at 2.09 Li2O

Indicated and 13.6 Mt at 1.99 Li2O Inferred.

• At a 1.5% Li2O COG for the CV13 Pegmatite, there is a total of 0.7 Mt at 2.20 Li2O

Indicated and 6.6 Mt at 2.47 Li2O Inferred.

Both the Nova and Vega zones have been traced over a significant distance/area with multiple drill

hole intercepts (core length) ranging from 2 to 25 m (CV5) and 2 to 10 m (CV13) at >5% Li 2O,

each within a significantly wider mineralized pegmatite zone of >2% Li2O (Figure 16, Figure 25, and

Figure 26). These zones are located approximately 6 km apart, along the same geological trend,

and emphasize not only the scale of the entire mineralized system at Shaakichiuwaanaan but also

its robustness in mineralized intensity defined to date.

The following Table 3 and Figure 4 outline the corresponding tonnage and lithium grade at various

cut-off grades for the Shaakichiuwaanaan MRE. In addition to evaluating sensitivities to cut -off

grades, this table can help relate the tonnage and grades at Shaakichiuwaanaan more directly to

those calculated for peer deposits, which may have applied different cut -off grades to their

resources.

Table 3: Sensitivity Analysis for the Shaakichiuwaanaan MRE.

1. This table should not be interpreted as a Mineral Resource. The table presents the sum of the open -pit and

underground constrained and classified resources at the same cut -off. The data is presented to demonstrate the

Mineral Resource tonnage and grade sensitivity to various cut -off grades. The selected cut -off grade for the base

case is 0.40% Li2O with the revenue factor 1 pit shell constraint for CV5 and CV13, with a 0.60% Li2O and 0.80%

Li2O underground cut-off grade for CV5 and CV13, respectively.
