MONTREAL , July 20, 2025 /PRNewswire/ – SYDNEY, Australia – July 21, 2025
HIGHLIGHTS
World’s largest pollucite-hosted caesium pegmatite deposit confirmed at the Shaakichiuwaanaan Project, with a maiden Mineral Resource Estimate (“Caesium Zone MRE”) of:Rigel Caesium ZoneIndicated: 163,000 t at 10.25% Cs2O, 1.78% Li2O, and 646 ppm Ta2O5.Vega Caesium ZoneIndicated: 530,000 t at 2.61% Cs2O, 2.23% Li2O, and 172 ppm Ta2O5.Inferred: 1,698,000 t at 2.40% Cs2O, 1.81% Li2O, and 245 ppm Ta2O5.Total contained caesium content of 30.5 kt Cs2O Indicated and 40.8 kt Cs2O Inferred, highlighting the scale and global significance of the discovery.Caesium resources in the Rigel and Vega zones are now included within the CV13 Pegmatite open-pit resource that forms part of the Company’s consolidated MRE for the Project (including both the CV5 and CV13 pegmatites) (“Consolidated MRE”) – that has been updated and restated as follows:Indicated: 108.0 Mt at 1.40% Li2O, 0.11% Cs2O, 166 ppm Ta2O5, and 66 ppm Ga.Inferred: 33.4 Mt at 1.33% Li2O, 0.21% Cs2O, 155 ppm Ta2O5, and 65 ppm Ga.Caesium is a high-value, rare, and critical mineral which is currently supply constrained with only limited sources supplying the global market1. A discovery of this size, grade, and scale has the potential to be a primary source of supply for the global market, including new and potentially growing applications in emerging next generation terrestrial solar panel applications where caesium has been found to play a vital role in significantly improving panel efficiency, stability, and life span.The Company has commenced evaluating options (including a scoping metallurgical program to test pollucite recovery using conventional X-ray ore sorting methods) to advance and incorporate the caesium opportunity at CV13 as a potential additional saleable product into the overall economic development of the Project – to follow completion of the lithium-only Feasibility Study on the CV5 Pegmatite.The Company remains on track to deliver a maiden Ore Reserve and Feasibility Study for lithium at the CV5 Spodumene Pegmatite in CYQ3-2025.
________________________________
1 Mineral deposits of pollucite-hosted caesium are extremely rare globally and represent the most fractionated component of LCT pegmatite systems, which are effectively the only primary and economic source of caesium globally. The Company is aware of only three previous pollucite-hosted caesium mines with Bikita in Zimbabwe and Sinclair in Western Australia now reportedly exhausted and Tanco in Manitoba, Canada, approaching the end of its mine-life.
Darren L. Smith, Executive and Vice President of Exploration for the Company, comments: “At Shaakichiuwaanaan, we have now defined the largest reported occurrence of pollucite in the world – by a significant margin. To find a pollucite-hosted caesium deposit of this scale and grade is exceptionally rare, with only three deposits globally known to have produced this extremely high-value critical and strategic mineral.”
“The pegmatites of the Shaakichiuwaanaan Project continue to demonstrate their unique, world-class nature for hosting abundant and varied critical minerals. With considerable Mineral Resources for lithium, tantalum, gallium, and now caesium defined – and a Feasibility Study for lithium at CV5 on schedule for completion this quarter – the Company is becoming increasingly well-positioned as an emerging critical minerals powerhouse to global markets.”
Ken Brinsden, President, CEO, and Managing Director, comments: “This is another feather in the cap of our technical team, led by Darren, with their hard work resulting in yet another world-class discovery at Shaakichiuwaanaan. What stands out is the sheer scale and grade of this caesium discovery, relative to anything that’s been found before globally.
It’s also a reflection of the extraordinary geology of this deposit, which hosts lithium, tantalum, and now caesium – all high-value critical minerals – at world-class scale. Given the scale, grade, and proximity to the CV5 Pegmatite, the new caesium discovery at Rigel and Vega has already added further substantial value to the Shaakichiuwaanaan Project.”
“What is particularly exciting for investors is that the addressable market for caesium appears to be at a key inflexion point, with its ability to improve the efficiency and stability of next generation terrestrial solar technologies having the potential to drive a massive increase in global demand. Shaakichiuwaanaan stands to play a driving role in the growth of this exciting new market. As we finalize the maiden lithium-only Feasibility Study for the CV5 Pegmatite, we are excited to start work on unlocking the enormous potential of the caesium resource, now outlined to NI 43-101 and JORC standards, for our shareholders,” added Mr. Brinsden.
PATRIOT BATTERY METALS INC. (THE “COMPANY” OR “PATRIOT”) (TSX: PMET) (ASX: PMT) (OTCQX: PMETF) (FSE: R9GA) is pleased to announce a maiden Mineral Resource Estimate for caesium (the “Caesium Zone MRE”) at the Rigel and Vega zones at its 100%-owned Shaakichiuwaanaan Property (the “Property” or “Project”) located in the Eeyou Istchee James Bay region of Quebec. The Rigel and Vega zones are hosted within the CV13 Pegmatite, which is located ~3 km west-southwest along geological trend of the CV5 Pegmatite that is accessible year-round by all-season road, and is situated ~13 km south of the all-weather Trans-Taiga Road and powerline corridor.
The Company has now confirmed that the Shaakichiuwaanaan Project hosts the world’s largest pollucite-hosted caesium pegmatite deposit (Figure 1, Figure 2, Figure 3, Table 2) after declaring a maiden Caesium Zone MRE of:
Rigel Caesium ZoneIndicated: 163,000 t at 10.25% Cs2O, 1.78% Li2O, and 646 ppm Ta2O5.Vega Caesium ZoneIndicated: 530,000 t at 2.61% Cs2O, 2.23% Li2O, and 172 ppm Ta2O5.Inferred: 1,698,000 t at 2.40% Cs2O, 1.81% Li2O, and 245 ppm Ta2O5.
The Caesium Zone MRE for Rigel and Vega, hosted within the open-pit resource component of the CV13 Pegmatite – which forms part of the Company’s Consolidated MRE for the Project (including both the CV5 and CV13 pegmatites) – has a total contained caesium metal content of 30.5 kt Cs2O Indicated and 40.8 kt Cs2O Inferred. The Rigel and Vega zones were interpreted using a 0.50% Cs2O grade constraint based on mineral processing analogues and mineralogical analysis supporting pollucite as the predominant Cs-bearing mineral present. Coincident with the pollucite-hosted caesium at Rigel and Vega is high-grade lithium and tantalum, present in the host minerals spodumene and tantalite, respectively, which may be co-recovered as separate concentrates.
The footprint of caesium mineralization at Rigel has been traced over a general area of at least 200 m x 100 m and consists of a single, shallow dipping lens at a depth of ~50 m with a true thickness of <2 m to ~6 m. At the Vega Zone, the footprint of the caesium mineralization has been traced over a general area of at least 800 m x 250 m and consists of two proximal flat-lying lenses, at a depth of ~110 m, with a true thickness of <2 m and up to ~10 m and ~6 m, respectively (Figure 1, Figure 9, Figure 10, Figure 21) .
The Consolidated MRE2, which includes the Rigel and Vega caesium zones, was most recently announced on May 12, 2025; however, that has now been updated and restated herein this announcement with the inclusion of caesium reporting as part of the overall consolidated resources for the CV5 and CV13 pegmatites.
The restatement of the Consolidated MRE also includes a minor adjustment to the tonnage and tantalum grade at the CV13 Pegmatite. The Consolidated MRE is as follows (Table 1).
Indicated: 108.0 Mt at 1.40% Li2O, 0.11% Cs2O, 166 ppm Ta2O5, and 66 ppm Ga.Inferred: 33.4 Mt at 1.33% Li2O, 0.21% Cs2O, 155 ppm Ta2O5, and 65 ppm Ga.
__________________________________
2 The Consolidated MRE cut-off grade is variable depending on the mining method and pegmatite (0.40% Li2O open-pit, 0.60% Li2O underground CV5, and 0.70% Li2O underground CV13). A grade constraint of 0.50% Cs2O was used to model the Rigel and Vega caesium zones, which are entirely within the CV13 Pegmatite's open-pit mining shape. The Effective Date of the MREs is June 20, 2025 (through drill hole CV24-787). Mineral Resources are not Mineral or Ore Reserves as they do not have demonstrated economic viability.
ABOUT CAESIUM
Mineral deposits of pollucite-hosted caesium are extremely rare globally and represent the most fractionated component of LCT pegmatite systems, which are effectively the only primary economic source of caesium globally. Economic deposits of caesium pegmatite are typically on a smaller scale of <10 kt to 350 kt in size compared to deposits of lithium pegmatite that typically range in the millions of tonnes in size (99.5%), is a high value commodity comparable to gold and currently trades around US$2,540/oz (or ~US$81 per gram4) (excluding VAT, Price Sourcing – Shanghai Metal Markets).
Caesium is currently supply constrained, with only limited sources supplying the global market. A discovery of this size, grade, and scale has the potential to be a primary source of supply for global markets. This includes existing applications for caesium in oil/gas drilling, medical imaging and now new and potentially growing applications in the terrestrial solar panel industry which has the potential to drive a significant increase in global demand. Caesium has been found to play a vital role in significantly improving next generation solar panel efficiency, stability, and life span through the application of perovskite crystal structures.

NEXT STEPS
With the maiden MRE for the Rigel and Vega caesium zones now completed, the Company is actively evaluating options to advance and incorporate the caesium opportunity at CV13 as a potential additional saleable product into the overall economic development of the Project – to follow completion of the lithium-only Feasibility Study on the CV5 Pegmatite.
This includes completing various environmental baseline studies and additional drilling to further convert Inferred Resources to the Indicated category and in support of future development (e.g. geomechanical drill holes). Additionally, the Company has commenced industry engagement with end users of caesium as well as initiated a scoping metallurgical program targeting pollucite mineral recovery using conventional X-ray ore sorting methods, which will inform a more expansive test program that will also include subsequent recovery of spodumene (lithium) and tantalite (tantalum). The scoping metallurgical program is using mineralized drill core collected from the Vega Caesium Zone with subsequent testwork to expand to the Rigel Caesium Zone.
In addition, the Company is also focused on completion of the remaining deliverables for its lithium-focused Feasibility Study on the CV5 Pegmatite. The Feasibility Study is well advanced and remains on schedule for completion in CYQ3-2025, with the Company recently announcing an update on its progress on March 18, 2025.

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 Mineral 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 resource estimate is Todd McCracken, P.Geo., Director – Mining & Geology – Central Canada, BBA Engineering Ltd. The Effective Date of the estimate is June 20, 2025 (through drill hole CV24-787).Estimation was completed using a combination of inverse distance squared (ID2) and ordinary kriging (OK) for CV5 and inverse distance squared (ID2) for CV13 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 the Consolidated MRE Statement 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% Li2O for CV5 and 0.70% Li2O for CV13. Open-pit and underground Mineral Resource constraints are based on a long-term average spodumene concentrate price of US$1,500/tonne (6% basis FOB Bécancour) and an exchange rate of 0.70 USD/CAD.Mineral Resources for the Rigel and Vega zones are hosted within the CV13 Pegmatite’s open-pit conceptual mining shape and, therefore, are included within the Consolidated Mineral Resource Statement for CV5 and CV13 pegmatites. The Rigel and Vega zones were interpreted using a 0.50% Cs2O grade constraint based on mineral processing analogues and mineralogical analysis supporting pollucite as the predominant Cs-bearing mineral present.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, Cs2O = Cs x 1.0602Densities for pegmatite blocks (both CV5 & CV13) were estimated using a linear regression function (SG = 0.0674x (Li2O% + 0.81 x B2O3%) + 2.6202) 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.
SENSITIVITY ANALYSIS
The following Table 3 and Figure 4 outline the corresponding tonnage and caesium grade at various cut-off grades for the Caesium Zone MREs, hosted within the CV13 Pegmatite and the Consolidated 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 Caesium at the Rigel and Vega Zones.
1.
This table should not be interpreted as a Mineral Resource. The data is presented to demonstrate the tonnage and grade sensitivity to various cut-off grades. The selected grade constraint for modelling the Rigel and Vega caesium zones was 0.50% Cs2O.
2.
Errors may occur in totals due to rounding.
GEOLOGICAL AND BLOCK MODELS
The Rigel and Vega caesium zones have been geologically modelled using a 0.50% Cs2O grade constraint within the wider CV13 Pegmatite body (Figure 1). The grade constraint is supported by mineralogical analysis that confirms pollucite as the predominant caesium-bearing mineral above this threshold and which may be recoverable using well-understood mineral processing methods. These geological models acted as hard boundaries within the wider CV13 Pegmatite body for subsequent block modelling and resource estimation.
Using the 0.5% Cs2O grade constraint, the footprint of caesium mineralization at Rigel has been traced over a general area of at least 200 m x 100 m and consists of a single, shallow dipping lens at a depth of ~50 m with a true thickness of <2 m to ~6 m. At the Vega Zone, the footprint of the caesium mineralization has been traced over a general area of at least 800 m x 250 m and consists of two proximal flat-lying lenses, at a depth of ~110 m, with a true thickness of <2 m and up to ~10 m and ~6 m, respectively
The geological and block models, classification, and sections for the Rigel and Vega zones are presented in Figure 5 through Figure 10. Respective figures for the CV13 and CV5 pegmatites are presented in the Company's news release dated May 12, 2025, as well as Figure 11 to Figure 14 for ease of reference herein.

ASX LISTING RULE 5.8
As the Company is listed on both the Toronto Stock Exchange (the "TSX") as well as the Australian Securities Exchange (the "ASX"), there are two applicable regulatory bodies resulting in additional disclosure requirements. This MRE has been completed in accordance with the Canadian National Instrument 43-101 – Standards of Disclosure for Mineral Projects. Additionally, in accordance with ASX Listing Rule 5.8 and the JORC 2012 reporting guidelines, a summary of the material information used to estimate the Mineral Resource for the Rigel and Vega caesium zones at the Shaakichiuwaanaan Project is detailed below. For additional information, please refer to JORC Table 1, Section 1, 2, and 3, as presented in Appendix 1 of this announcement.
As the change in lithium, tantalum, and gallium Mineral Resources for the Consolidated MRE, which includes both the CV5 and CV13 pegmatites, is considered not a material change (as presented herein Table 1), the detailed summary, figures/diagrams, and technical parameters applied as presented in the original announcement dated May 12, 2025, remain current and are not duplicated below.
MINERAL TITLE
The Shaakichiuwaanaan Property is located approximately 220 km east of Radisson, QC, and 240 km north-northeast of Nemaska, QC. The northern border of the Property's primary claim grouping is located within approximately 6 km to the south of the Trans-Taiga Road and powerline infrastructure corridor (Figure 15). The La Grande-4 (LG4) hydroelectric dam complex is located approximately 40 km north-northeast of the Property. The CV5 Spodumene Pegmatite is located central to the Property, ~13 km south of KM-270 on the Trans-Taiga Road, and is accessible year-round by all-season road. The CV13 Spodumene Pegmatite is located ~3 km west-southwest of CV5.
The Property is comprised of 463 Exclusive Exploration Rights ("EER") (formerly known as CDC mineral claims) that cover an area of approximately 23,710 ha. All claims are registered 100% in the name of Lithium Innova Inc., a wholly owned subsidiary of Patriot Battery Metals Inc.
GEOLOGY AND GEOLOGICAL INTERPRETATION
The Property overlies a large portion of the Lac Guyer Greenstone Belt, considered part of the larger La Grande River Greenstone Belt, and is dominated by volcanic rocks metamorphosed to amphibolite facies. Rocks of the Guyer Group (amphibolite, iron formation, intermediate to mafic volcanics, peridotite, pyroxenite, komatiite, as well as felsic volcanics) predominantly underly the Property (Figure 20). The amphibolite rocks that trend east-west (generally steeply south dipping) through this region are bordered to the north by the Magin Formation (conglomerate and wacke) and to the south by an assemblage of tonalite, granodiorite, and diorite, in addition to metasediments of the Marbot Group (conglomerate, wacke) in the areas proximal to the CV5 Spodumene Pegmatite. Several regional-scale Proterozoic gabbroic dykes also cut through portions of the Property (Lac Spirt Dykes, Senneterre Dykes). The lithium pegmatites on the Property are hosted predominantly within amphibolites, metasediments, and to a lesser extent ultramafic rocks.
At the Property, caesium mineralization is observed to occur within lithium-caesium-tantalum ("LCT") pegmatites, which may be exposed at surface as both low and high relief landforms (i.e., outcrops) or present under shallow glacial till cover (Figure 16). To date, the LCT pegmatites at the Property have been observed to occur within a corridor of generally ~1 km in width that extends in a general east-west direction across the Property for at least 25 km – the 'CV Lithium Trend' – with significant areas of prospective trend that remain to be assessed (Figure 20). To date, nine (9) distinct lithium pegmatite clusters have been reported along the CV Lithium Trend at the Property – CV4, CV5, CV8, CV9, CV10, CV12, CV13, CV14, and CV15 (Figure 19). Of these clusters, CV5, CV12, and CV13 have documented pollucite hosted caesium mineralization from drill hole and/or channel sampling. Pollucite is an extremely rare mineral occurrence in LCT pegmatites and represents the most fractionated components of the system.
The Consolidated MRE for the Project, which includes the CV5 and CV13 pegmatites, represents the core area of the trend. The CV5 and CV13 pegmatites are situated along the same geological trend, with approximate strike lengths of 4.6 km and 2.5 km, respectively – as defined by drilling to date and which remain open – and are separated by a distance of ~2.6 km (Figure 19). Consolidated MRE covers ~6.9 km of the ~7.1 km of defined pegmatite trend and remains open.
The Consolidated MRE is described in detail, with respect to Li, Ta, and Ga, in news announcement dated May 12, 2025. The Rigel and Vega Caesium Zone MREs are hosted within the CV13 Pegmatite, therefore forming part of the Consolidated MRE for the Project, and are described in further detail herein.
The LCT pegmatites at the Property, including CV5 and CV13, are very coarse-grained and off-white in appearance, with darker sections commonly composed of smoky quartz with occasional mica and tourmaline
The Rigel and Vega caesium zones – nested entirely within the CV13 Pegmatite – are marked by significant occurrences pollucite-hosted caesium. The pollucite is typically centimetre to decimetre-metre scale, presenting as clear to whitish-grey in colour with common late-stage veining of white pollucite or spodumene, or purple lepidolite as well as common white flecks. It may be significantly more difficult to ascertain to the naked eye compared to spodumene (Figure 3, Figure 17, and Figure 18). The pollucite also commonly occurs with significant amounts of spodumene (lithium) and tantalite (tantalum).
Using the 0.5% Cs2O grade constraint, the footprint of caesium mineralization at the Vega Caesium Zone has been traced over a general area of at least 800 m x 250 m and consists of two proximal flat-lying lenses, at a depth of ~110 m, with a true thickness of <2 m and up to ~10 m and ~6 m, respectively. At Rigel, the footprint of caesium mineralization has been traced over a general area of least 200 m x 100 m and consists of a single, shallow dipping lens at a depth of ~50 m with a true thickness of <2 m to ~6 m.
The pollucite zones at Rigel and Vega are also coincident with moderate to high abundances of spodumene (lithium) and tantalite (tantalum).

DRILLING TECHNIQUES AND CLASSIFICATION CRITERIA
The Shaakichiuwaanaan database includes 801 diamond drill holes completed over the 2021, 2022, 2023, and 2024 programs, for a collective total of 234,671 m, as well as outcrop channels totalling 800 m. Of these, the 32 holes totalling 7,808 m, completed over the 2022, 2023, and 2024 programs, as well as 7 m of channels, were used to support the Vega and Rigel Caesium Zone MRE and geological models.
The Rigel MRE and geological models are supported by 6 diamond drill holes of NQ size totalling 1,228 m. The Vega MRE and geological models are supported by 26 diamond drill holes of NQ size totalling 6,580 m, and 7 m of channels.
Each drill hole collar was surveyed with an RTK tool (Topcon GR5 or Trimble Zephyr 3) (Table 4). Downhole deviation surveys for each drill hole were completed with a Devico DeviGyro tool (2021 and 2024 holes), Reflex Gyro Sprint IQ tool (2022, 2023, and 2024 holes), Axis Champ Gyro (2023 and 2024 holes), or Reflex OMNI Gyro Sprint IQ (2024 holes). Survey shots were typically continuous at approximate 3-5 m intervals. The use of the gyro tool system negated potential deflection issues arising from minor but common pyrrhotite within the host rock units. All collar and downhole deviation data have been validated by the project geologists on site, and by the database lead.
Drill core has not been oriented; however, downhole optical and acoustic televiewer surveys have been completed on multiple holes, at both CV5 and CV13, to assess overall structure. This data guided the current geological models supporting this Rigel and Vega MREs.
At CV13, drill hole spacing is a combination of grid based (at ~100 m spacing) and fan based (Figure 21). Several collars are typically completed from the same pad at varied orientations targeting pegmatite pierce points of ~50 to 100 m spacing depending on the resource classification being tar
