Smith, Executive Vice President Exploration for the Company, comments:_" The recent surface exploration at Shaakichiuwaanaan has delivered multiple new discoveries with strong results that continue to support the scale and growth potential for lithium, caesium, and tantalum across the Property. The discovery of a new caesium- rich LCT pegmatite occurrence (Cosma), located along the highly prospective Mickel Trend – which also hosts the CV9, CV10, CV14, and CV15 pegmatites – supports the presence of a large, highly-evolved, and fertile LCT pegmatite system within the western area of the Property, which has seen only limited drill testing to date._ _Additionally, the presence of well-mineralized LCT pegmatites at Pikwa, Pontois, and Pontax demonstrates the strength and prospectivity of the Company’s broader portfolio of properties," _added Mr. Smith. **PMET RESOURCES INC. (THE "COMPANY" OR "PMET")** (TSX: PMET) (ASX: PMT) (OTCQX: PMETF) (FSE: R9GA) is pleased to announce multiple new Li-Cs-Ta ("LCT") pegmatite discoveries at its flagship Shaakichiuwaanaan Property, as well as at its broader portfolio of properties (Pikwa, Pontois, and Pontax), all located in Eeyou Istchee James Bay, Quebec (**Figure 1**). In addition to the Company’s core discoveries and resources at the CV5 and CV13 pegmatites, exploration activities continue within the near-field core Shaakichiuwaanaan area and across the adjacent regional tenure (**Figure 2**). Collectively, the Shaakichiuwaanaan, Pikwa, and Pontois properties cover more than 70 km of continuous and highly prospective greenstone belt, which the Company believes to be the most significant trend for LCT pegmatites in North America. [⌊Figure 1: Location of the Company’s portfolio of properties in the Eeyou Istchee James Bay, Quebec.⌉](https://mma.prnasia.com/media2/2992505/PMET_Resources_Inc__New_High_grade_Lithium__Caesium__and_Tantalu.jpg?p=medium600) Figure 1: Location of the Company’s portfolio of properties in the Eeyou Istchee James Bay, Quebec. The Shaakichiuwaanaan Property is the Company’s flagship asset and hosts one of the largest pegmatite Mineral Resources^(1) (Li, Cs, Ta) and Mineral Reserves^(2)( Li) in the world (**Figure 1** and **Figure 2**), situated approximately 13 km south of the regional and all-weather Trans-Taiga Road (accessible year-round by road) and Hydro Quebec infrastructure corridor. The Company recently announced a robust lithium-only Feasibility Study for the CV5 Pegmatite, which positions the Project as a potential North American critical mineral powerhouse (see news release dated [October 20, 2025](https://edge.prnewswire.com/c/link/?t=0&l=en&o=4701287-1&h=4026498528&u=https%3A%2F%2Fwww.pmet.ca%2Fnews%2Fpmet-resources-delivers-positive-cv5-lithium-only-feasibility-study-for-its-large-scale-shaakichiuwaanaan-project%2F&a=October+20%2C+2025)).

See Feasibility Study news release dated October 20, 2025._ | **SHAAKICHIUWAANAAN (PLUS PIKWA AND PONTOIS)** **Cosma LCT Pegmatite** Several outcropping and well-mineralised LCT pegmatite discoveries have been made at Shaakichiuwaanaan in recent surface exploration. This includes the **Cosma Pegmatite**( outcrop), which returned significant grades of caesium and tantalum in initial grab sampling in 2025 – **9.42% Cs_(2)O **and **267 ppm Ta_(2)O_(5) **(0.01% Li_(2)O). Follow-up channel sampling returned **4.4 m at** **3.61% Cs_(2)O **and **609 ppm Ta_(2)O_(5)**, including **0.5 m at** **16.43% Cs_(2)O **(CH25-133), confirming the significance of the surface exposure (**Figure 2** and **Figure 3**). [⌊Figure 3: Channel sample at the newly discovered Cosma Caesium Pegmatite, assaying 0.5 m at 16.43% Cs2O.⌉](https://mma.prnasia.com/media2/2992507/PMET_Resources_Inc__New_High_grade_Lithium__Caesium__and_Tantalu.jpg?p=medium600) Figure 3: Channel sample at the newly discovered Cosma Caesium Pegmatite, assaying 0.5 m at 16.43% Cs2O. The Cosma Pegmatite is expressed at surface as a ~8 x 4 m white outcrop and is open in multiple directions. The outcrop is situated approximately 2.5 km along trend to the west-southwest of the CV15 pegmatite cluster and – together with the Felix and Drakkar spodumene pegmatites discussed below – now **extends the Mickel LCT Pegmatite Trend to ~10.5 km** (from the previous 5.5 km) (**Figure 4**). Of this ~10.5 km length, only the CV9 Pegmatite – at the eastern-most end of the trend – has been drill tested. Drill results at CV9 include 30.6 m at 0.80% Li_(2)O (CV23- 345), 10.8 m at 1.00% Li_(2)O (CV23-267), and 7.7 m at 1.35% Li_(2)O (CV23-333), with an area of the pegmatite estimated at up to 80 m true width, demonstrating significant scale potential (see news release dated [April 8, 2024](https://edge.prnewswire.com/c/link/?t=0&l=en&o=4701287-1&h=1839842762&u=https%3A%2F%2Fwww.pmet.ca%2Fnews%2Fpatriot-announces-final-2023-drill-hole-results-for-the-cv13-and-cv9-pegmatites-corvette-quebec-canada%2F&a=April+8%2C+2024)). Cosma is the westernmost occurrence of caesium pegmatite encountered at Shaakichiuwaanaan to date. The discovery is very encouraging, as most caesium deposits (apart from the world-class Vega Caesium Zone at the CV13 Pegmatite held by the Company) tend to be on the order of tens- to hundreds-of-thousands of tonnes. Therefore, relatively small occurrences can mark very material discoveries – especially when exposed at surface. The Company intends to follow-up on this discovery during the 2026 surface program. [⌊Figure 4: Compilation of surface sampling results along the Mickel LCT Pegmatite Trend (part of the greater CV Lithium Trend) at Shaakichiuwaanaan, now extending onto the adjacent Pikwa Property.⌉](https://mma.prnasia.com/media2/2992508/PMET_Resources_Inc__New_High_grade_Lithium__Caesium__and_Tantalu.jpg?p=medium600) Figure 4: Compilation of surface sampling results along the Mickel LCT Pegmatite Trend (part of the greater CV Lithium Trend) at Shaakichiuwaanaan, now extending onto the adjacent Pikwa Property. A total of 355 rock samples (outcrop, boulder, and channels) were collected during the 2025 exploration of the Shaakichiuwaanaan Property, with results ranging from <0.01 to 4.51% Li_(2)O, <5 to 2,580 ppm Ta_(2)O_(5), and <0.01 to 16.43% Cs_(2)O. Exploration was focused on LCT pegmatite. **Felix & Drakkar LCT Pegmatites** Additionally, the Company is pleased to announce an emerging **discovery of LCT Pegmatite called Felix**, located near the western margins of the Shaakichiuwaanaan Property, proximal to the recently acquired Pikwa Property and its Drakkar Spodumene Pegmatite. The Felix Pegmatite is characterized by a cluster of multiple mineralized outcrops spread over a ~450 m trend, with assays including **1.80% Li_(2)O and 1.21%**** Li_(2)O** in outcrop**. **Channel sampling at Felix is planned for the 2026 exploration field program. The **Drakkar LCT Pegmatite** **(2.45% Li_(2)O **in outcrop), discovered by Azimut Exploration and Soquem, is situated ~550 m to the southwest of the Felix Pegmatite on the adjoining Pikwa Property, which is now held 100% by the Company (see news release dated [November 12, 2025](https://edge.prnewswire.com/c/link/?t=0&l=en&o=4701287-1&h=2238955134&u=https%3A%2F%2Fwww.pmet.ca%2Fnews%2Fpmet-resources-to-expand-land-position-in-james-bay-region%2F&a=November+12%2C+2025)). The Company is currently designing an inaugural surface exploration program at Pikwa, which will be focused on LCT pegmatite. Historical exploration of the Pikwa Property was focused on base and precious metals with several notable discoveries including the **Hyperion** **Prospect**^(3) (**7.17 g/t Au** in outcrop) and the **Copperfield Prospect**^(4) (**13.45 g/t Au, 9.81 % Cu, and 37.6 g/t Ag** in outcrop). However, the primary greenstone belt trend has seen only limited exploration focused on LCT pegmatite (**Figure 5**). **Skald LCT Pegmatite** The Skald LCT Pegmatite was discovered in 2025 during surface exploration of the Pontois Property, which is situated immediately adjacent to the western border of the Pikwa Property (**Figure 5**). The **Skald Pegmatite **is characterized by a spodumene-bearing pegmatite outcrop of ~2 m x 3 m in size (open), with a sample assay of **2.94% Li_(2)O and 60 ppm Ta_(2)O_(5)**. The discovery is very promising as it highlights the potential of the ~12 km’s of highly prospective greenstone belt corridor at the Pikwa Property where only limited LCT pegmatite exploration has been completed historically. Coupled with Pikwa and Shaakichiuwaanaan, the Company controls more than 70 km of the La Grande Greenstone Belt, which is considered highly prospective for LCT pegmatite and is host to the world-class CV5 (Li-Ta) and CV13 (Li-Cs-Ta) pegmatite deposits currently under development.  A total of 69 rock samples (outcrop and boulder) were collected during the 2025 exploration of the Pontois Property, with results ranging from <0.01 to 2.94% Li_( 2)O, <5 to 60 ppm Ta_(2)O_(5), and <0.01% to 0.077% Cs_(2)O. Exploration was focused on LCT pegmatite.

The sample was collected from a 0.5 – 1 m wide by >50 m long white pegmatite dyke, which remains open along strike. Although not identified during field observations, the presence of pollucite( and likely columbo-tantalite) are inferred given the grades, as well as mineralogy confirming the presence of both minerals at the nearby Resisto Showing. Next to Pikwa, the Pontax Property is the most advanced regional asset in the Company’s portfolio. Prior exploration has discovered a multi-kilometre long trend containing a significant number of well-mineralized (in Li and Ta) LCT pegmatite outcrops – namely, Resisto (2.86% Li_(2)O; 9,152 ppm Ta_(2)O_(5)), Inducto (2.69% Li_(2)O; 397 ppm Ta_(2)O_(5)), and Capacito (3.81% Li_(2)O; 365 ppm Ta_(2)O_(5)) (**Figure 5**). The Resisto Showing is the most significant occurrence, characterized by a swarm of white pegmatite outcrops, with channel sampling (completed in 2022) returning considerable tantalum grades – **12.1 m **at 0.55% Li₂O and **2,166 ppm Ta****₂O**** ₅**, including **4.0 m at 4,596 ppm Ta****₂O****₅.** The Overload Showing is situated approximately 1.6 km along strike of the Resisto Showing, with the **prospective trend now expanded to over 3.7 km between Capacito and Overload**. None of the showings along this trend have been drill tested. [⌊Figure 6: Summary of LCT pegmatite showings at the Pontax Property (Block C).⌉](https://mma.prnasia.com/media2/2992510/PMET_Resources_Inc__New_High_grade_Lithium__Caesium__and_Tantalu.jpg?p=medium600) Figure 6: Summary of LCT pegmatite showings at the Pontax Property (Block C). A total of 54 rock samples (outcrop and boulder) were collected during the 2025 exploration of the Pontax Property with results ranging from <0.01% to 2.65% Li_( 2)O, <5 to 3,768 ppm Ta_(2)O_(5), and <0.01% to 7.53% Cs_(2)O. Additionally, one sample collected from an amphibolite outcrop, approximately 35 m from the Overload Showing, assayed **1.02 g/t Au, 17 g/t Ag, and 1.11% Cu **(the "Subordi" Showing). Exploration was focused on LCT pegmatite. **Next Steps** The 2025 surface exploration programs at Shaakichiuwaanaan, Pontois, and Pontax, included geological mapping, regional prospecting, and surface sampling and was focused on the discovery of new LCT pegmatite occurrences. Collectively, over 400 rock samples were collected in 2025, with notable LCT pegmatite occurrences discovered at each of the three properties. The discoveries highlight the prospective nature of the Company’s broader portfolio of properties, and further enhance the prospectivity of its flagship Shaakichiuwaanaan asset.   The Company is currently planning follow-up surface work in 2026 at its Shaakichiuwaanaan, Pikwa (inaugural program), and Eastmain properties, and is evaluating options for the next stage of exploration at Pontax. **QUALITY ASSURANCE / QUALITY CONTROL (QAQC)** The Company has relied on internal laboratory checks and blank / certified reference material insertion for surface rock samples. Management cautions that prospecting surface rock samples and associated assays, as discussed herein, are selective by nature and represent a point location, and therefore may not necessarily be fully representative of the mineralized horizon sampled. All surface samples collected were shipped to SGS Canada’s laboratory in Val-d’Or, 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 analyzed for multi-element (including Li and Ta) using sodium peroxide fusion with ICP-AES/MS finish (codes GE_ICP91A50 and GE_IMS91A50). Overlimits for Cs were completed at SGS Canada’s laboratory in Lakefield, ON, by borate-fusion XRF (code GC_XRF76V). **QUALIFIED/COMPETENT PERSON** The technical and scientific information in this news release that relates to the Mineral Resource  Estimate and exploration results for the Company’s properties is based on, and fairly represents, information compiled by Mr. Darren L.

For a summary of previous exploration undertaken by other parties at Shaakichiuwaanaan, please refer to the most recent NI 43-101 Technical Report. Historical exploration focused on base and precious metals. ◦ At the Pontois and Pontax Properties, no previous exploration targeting LCT pegmatites has been conducted by other parties. Historical exploration focused on base and precious metals. ◦ At the Pikwa Property, historical exploration focused on base and precious metals. However, exploration for LCT pegmatite was completed circa 2024 and is considered limited in nature compared to the overall exploration completed at the Property.   | | Geology | ◦ Deposit type, geological setting and style of mineralization.   | ◦ The Shaakichiuwaanaan, Pikwa, and Pontois properties overlie 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. The claim block is dominantly host to rocks of the Guyer Group (amphibolite, iron formation, intermediate to mafic volcanics, peridotite, pyroxenite, komatiite, as well as felsic volcanics). 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). Several regional-scale Proterozoic gabbroic dykes also cut through portions of the Property (Lac Spirt Dykes, Senneterre Dykes). ◦ The geological setting is prospective for multiple commodities over several different deposit styles including orogenic gold (Au), volcanogenic massive sulphide (Cu, Au, Ag), komatiite-ultramafic (Au, Ag, PGE, Ni, Cu, Co), and LCT pegmatite (Li, Cs, Ta, Ga, Rb). ◦ Exploration of the Shaakichiuwaanaan Property has outlined three primary mineral exploration trends crossing dominantly east-west over large portions of the Property – Golden Trend (gold), Maven Trend (copper, gold, silver), and CV Trend (lithium, caesium, tantalum). The CV4, CV5, CV8, CV12, and CV13 pegmatites are situated within the CV Trend.  ◦ The pegmatites at Shaakichiuwaanaan are categorized as Li-Cs-Ta ("LCT") pegmatites. LCT mineralization at the Property is observed to occur within quartz-feldspar pegmatite. The pegmatite is often very coarse-grained and off-white in appearance, with darker sections commonly composed of mica and smoky quartz, and occasional tourmaline.  ◦ Core assays and ongoing mineralogical studies, coupled with field mineral identification and assays confirm spodumene as the dominant lithium-bearing mineral on the Shaakichiuwaanaan Property, with no significant petalite, lepidolite, lithium-phosphate minerals, or apatite present. The spodumene crystal size of the pegmatites is typically decimeter scale, and therefore, very large. The pegmatites also carry significant tantalum (tantalite) and caesium (pollucite). Gallium is present in spodumene and feldspar via substitution with Al. ◦ The Pontax Property overlies a the Pontax/Chambois Greenstone Belt, extending southwest from the Eastmain River Greenstone Belt.   | | Drill hole Information | ◦ A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: ◦ easting and northing of the drill hole collar ◦ elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar ◦ dip and azimuth of the hole ◦ down hole length and interception depth ◦ hole length. ◦ If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case.   | ◦ N/A. No drill results reported.   | | Data aggregation methods | ◦ In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. ◦ Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. ◦ The assumptions used for any reporting of metal equivalent values should be clearly stated.   | ◦ N/A. No drill results reported.   | | Relationship between mineralization widths and intercept lengths | ◦ These relationships are particularly important in the reporting of Exploration Results. ◦ If the geometry of the mineralization with respect to the drill hole angle is known, its nature should be reported. ◦ If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’).   | ◦ N/A. No drill results reported.   | | Diagrams | ◦ Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported. These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views.   | ◦ Please refer to the figures included herein as well as those posted on the Company’s website.   | | Balanced reporting | ◦ Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results.   | ◦ Reporting is balanced.   | | Other substantive exploration data | ◦ Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances.   | ◦ All work discussed below pertains to the Shaakichiuwaanaan Property. ◦ The Company is currently completing site environmental work over the CV5 and CV13 pegmatite area. No endangered flora or fauna have been documented over the Property to date, and several sites have been identified as potentially suitable for mine infrastructure. ◦ The Company has completed a bathymetric survey over the shallow glacial lake which overlies a portion of the CV5 Spodumene Pegmatite. The lake depth ranges from <2 m to approximately 18 m, although the majority of the CV5 Spodumene Pegmatite, as delineated to date, is overlain by typically <2 to 10 m of water. ◦ The Company has completed significant metallurgical testing comprised of HLS and magnetic testing, which has produced 6+% Li_(2)O spodumene concentrates at >70% recovery on both CV5 and CV13 pegmatite material. A DMS test on CV5 Pegmatite material returned a Subsequent and more expansive DMS pilot programs completed, including with non-pegmatite dilution, produced results in line with prior testwork, confirming a DMS-only flowsheet is applicable. Piloting to date (using both drill core and boulders) has collectively produced over 4.5 tonnes of spodumene concentrate grading over 5.5% Li2O. ◦ The Company has also produced a marketable lithium hydroxide concentrate from CV5’s spodumene concentrate. ◦ The Company has produced marketable tantalite concentrates at bench-scale from the CV5 Pegmatite’s DMS (spodumene) tailings fractions. The testwork used gravity or gravity + flotation methods to produce tantalite concentrates grading 8.7% Ta_(2)O_(5) at 45% global recovery (MC001) and 6.6% Ta_(2)O_(5) at 49% global recovery (MC002). ◦ The Company has produced marketable pollucite concentrates at bench-scale from the CV13 Pegmatite’s Vega Caesium Zone. The testwork used XRT ore sorting to produce concentrates of 11.5% Cs_(2)O and 20.0% Cs_(2)O at an overall 88% recovery. ◦ Various mandates required for advancing the Project have been completed or are ongoing, including but not limited to, environmental baseline, metallurgy, geomechanics, hydrogeology, hydrology, stakeholder engagement, geochemical characterization, as well as transportation and logistical studies. A Feasibility Study for lithium-only on the CV5 Pegmatite was announced October 20, 2025.   | | Further work | ◦ The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). ◦ Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.   | ◦ The Company intends to continue drilling the pegmatites of the Shaakichiuwaanaan Property, primarily targetting lithium, caesium, and tantalum as the primary commodities of interest. This is anticipated to includes step-out and infill drilling. ◦ Further drilling is anticipated to support the development of the CV5 and CV13 pegmatites (i.e., resource, geotechnical, geomechanical, and hydrogeological). ◦ Metallurgical test programs evaluating the recovery of lithium, caesium, and tantalum are ongoing. ◦ Surface prospecting, rock sampling, and mapping is planned to continue across the Company’s portfolio of properties focused on LCT pegmatite.   |     [⌊Logo de Ressources PMET⌉](https://mma.prnasia.com/media2/2992517/PMET_Resources_Inc__New_High_grade_Lithium__Caesium__and_Tantalu.jpg?p=medium600) Logo de Ressources PMET Photo – [https://mma.prnasia.com/media2/2992505/PMET_Resources_Inc__New_High_grade_Lithium__Caesium__and_Tantalu.jpg?p=medium600](https://edge.prnewswire.com/c/link/?t=0&l=en&o=4701287-1&h=1783212210&u=https%3A%2F%2Fmma.prnewswire.com%2Fmedia%2F2992505%2FPMET_Resources_Inc__New_High_grade_Lithium__Caesium__and_Tantalu.jpg&a=https%3A%2F%2Fmma.prnewswire.com%2Fmedia%2F2992505%2FPMET_Resources_Inc__New_High_grade_Lithium__Caesium__and_Tantalu.jpg) Photo – [https://mma.prnasia.com/media2/2992506/PMET_Resources_Inc__New_High_grade_Lithium__Caesium__and_Tantalu.jpg?p=medium600](https://edge.prnewswire.com/c/link/?t=0&l=en&o=4701287-1&h=2381883123&u=https%3A%2F%2Fmma.prnewswire.com%2Fmedia%2F2992506%2FPMET_Resources_Inc__New_High_grade_Lithium__Caesium__and_Tantalu.jpg&a=https%3A%2F%2Fmma.prnewswire.com%2Fmedia%2F2992506%2FPMET_Resources_Inc__New_High_grade_Lithium__Caesium__and_Tantalu.jpg) Photo – [https://mma.prnasia.com/media2/2992507/PMET_Resources_Inc__New_High_grade_Lithium__Caesium__and_Tantalu.jpg?p=medium600](https://edge.prnewswire.com/c/link/?t=0&l=en&o=4701287-1&h=1715953395&u=https%3A%2F%2Fmma.prnewswire.com%2Fmedia%2F2992507%2FPMET_Resources_Inc__New_High_grade_Lithium__Caesium__and_Tantalu.jpg&a=https%3A%2F%2Fmma.prnewswire.com%2Fmedia%2F2992507%2FPMET_Resources_Inc__New_High_grade_Lithium__Caesium__and_Tantalu.jpg) Photo – [https://mma.prnasia.com/media2/2992508/PMET_Resources_Inc__New_High_grade_Lithium__Caesium__and_Tantalu.jpg?p=medium600](https://edge.prnewswire.com/c/link/?t=0&l=en&o=4701287-1&h=2849006900&u=https%3A%2F%2Fmma.prnewswire.com%2Fmedia%2F2992508%2FPMET_Resources_Inc__New_High_grade_Lithium__Caesium__and_Tantalu.jpg&a=https%3A%2F%2Fmma.prnewswire.com%2Fmedia%2F2992508%2FPMET_Resources_Inc__New_High_grade_Lithium__Caesium__and_Tantalu.jpg) Photo –  [https://mma.prnasia.com/media2/2992509/PMET_Resources_Inc__New_High_grade_Lithium__Caesium__and_Tantalu.jpg?p=medium600](https://edge.prnewswire.com/c/link/?t=0&l=en&o=4701287-1&h=1114610996&u=https%3A%2F%2Fmma.prnewswire.com%2Fmedia%2F2992509%2FPMET_Resources_Inc__New_High_grade_Lithium__Caesium__and_Tantalu.jpg&a=https%3A%2F%2Fmma.prnewswire.com%2Fmedia%2F2992509%2FPMET_Resources_Inc__New_High_grade_Lithium__Caesium__and_Tantalu.jpg) Photo –  [https://mma.prnasia.com/media2/2992510/PMET_Resources_Inc__New_High_grade_Lithium__Caesium__and_Tantalu.jpg?p=medium600](https://edge.prnewswire.com/c/link/?t=0&l=en&o=4701287-1&h=2566915016&u=https%3A%2F%2Fmma.prnewswire.com%2Fmedia%2F2992510%2FPMET_Resources_Inc__New_High_grade_Lithium__Caesium__and_Tantalu.jpg&a=https%3A%2F%2Fmma.prnewswire.com%2Fmedia%2F2992510%2FPMET_Resources_Inc__New_High_grade_Lithium__Caesium__and_Tantalu.jpg) Photo –  [https://mma.prnasia.com/media2/2992517/PMET_Resources_Inc__New_High_grade_Lithium__Caesium__and_Tantalu.jpg?p=medium600](https://edge.prnewswire.com/c/link/?t=0&l=en&o=4701287-1&h=1722605835&u=https%3A%2F%2Fmma.prnewswire.com%2Fmedia%2F2992517%2FPMET_Resources_Inc__New_High_grade_Lithium__Caesium__and_Tantalu.jpg&a=https%3A%2F%2Fmma.prnewswire.com%2Fmedia%2F2992517%2FPMET_Resources_Inc__New_High_grade_Lithium__Caesium__and_Tantalu.jpg) Olivier Caza-Lapointe, Head, Investor Relations, T: +1 (514) 913-5264, E: [ocazalapointe@pmet.ca](https://www.thailand-business-news.com/pr-news/ocazalapointe@pmet.ca) --- | This article was produced by Cision PR Newswire, our trusted news partner.
