"This final round of metallurgical test work and recent MRE has been compiled from over 7,000m of exploration drilling, demonstrating a strong amount of confidence to our shareholders and the market as we continue to de-risk the project in preparation for production." Cesium Chemical Production The Company has successfully produced cesium formate and cesium chloride, two globally highly sought cesium chemicals, from pollucite concentrate samples generated during Phase I ore sorting testwork the company completed in 2024 (see December 3, 2024, press release). The cesium chemicals conversion test work was conducted at SGS Canada, a leading metallurgical and testing laboratory located in Lakefield, Ontario, Canada. The testwork used a blended concentrate sample with an average feed grade of 19.5% Cs₂O, created from pollucite concentrates 24-036-01P and 24-036-03P, produced during Phase I ore sorting. The composite sample was crushed to 100% passing 106 μm and then underwent a series of tests including hot acid leaching, cesium alum crystallization, and liquor treatment, resulting in production of technical grade cesium formate and cesium chloride with purities of 99.8% and 99.6%, respectively (Figure 1-3). The pollucite concentrate exhibited a favourable response to hot sulphuric acid leaching, achieving 97% cesium extraction efficiency (Table 1). A two stage (50°C and 20°C) cesium alum crystallization was completed on the leach liquor to generate a high-quality crystal in the first stage, followed by residual cesium crystallization in the second stage low temperature crystallization (along with some rubidium and other impurities) . The majority of the cesium (up to 71%) was recovered at 50°C, with additional recovery achieved upon cooling to 20°C, resulting in crystallization efficiency rates between 95% and 98%. The crystals from 50°C stage were redissolved and subjected to similar two-stage recrystallization. Up to 89% of the material recrystallized at 50°C, with final efficiencies reaching up to 98% following the 20°C step (Table 3). Further purification and conversion tests were conducted on the 50°C pure cesium alum product, including the removal of aluminum (and some sulphate), and the subsequent conversion to cesium hydroxide. Cesium formate and cesium chloride were subsequently synthesized from the cesium hydroxide, meeting industry-standard specifications for low impurity levels in both compounds (Tables and 4, Figures 1 and 2). Additionally, the cesium formate solution demonstrated a density of 2.23 g/mL, which falls within the industry standard range of 2.2 g/mL to 2.4 g/mL for cesium formate. Table 2 – Summary of Crystallization Rates (%) for Two-Stage Crude Cesium Alum 3 __________________________________ 3 Reported results are based on the test yielding the highest Cs crystallization efficiency Table 3 – Summary assay results for cesium formate solution (Cs, Rb, Ag, Al, As, Bi, Cd, Co, Cr, Li, Mn, Mo, Ni, P, Pb, Sb, Se, Sn, Sr, Tl, V, and Y were analyzed via ICP-MS, TOC via Skalar TOC analyzer, all remaining elements were analyzed via ICP-AES) Table 4 – Summary assay methods for the cesium chloride crystals (Cs, Rb, and Pb were analyzed via ICP-MS, Cl via titration, all remaining elements were analyzed via ICP-AES) These initial tests show that the pollucite concentrate from Power Metals West Joe deposit can be efficiently converted into cesium formate and cesium chloride using established methods, with samples meeting industry specifications and low impurities.

HIGH-GRADE SPODUMENE AND TANTALUM CONCENTRATES CONFIRMED AT CASE LAKE
Outstanding results from Dense Media Separation (DMS) and flotation test work confirm the high quality and added value of lithium at the Case Lake Project: High 7.70% Li₂0 spodumene concentrate High 99.50% flotation stage recovery Low 0.66% iron (Fe₂O₃) impurities Confirms ability to achieve high lithium recovery and grades through DMS: High 5.24% Li₂0 spodumene concentrate High 85.82% recovery Low 0.54% iron (Fe₂O₃) impurities Tantalum results returned from Wet Table and Magnetic Separation test work produced high grades: 12,508 ppm (1.25%) Ta concentrate 45% recovery Test work on lithium and tantalum confirms potential to produce multiple high-value mineral products Case Lake remains the only cesium project currently in development globally – underpinned by the world's fourth largest cesium resource VANCOUVER, BC, July 7, 2025 /CNW/ - Power Metals Corp ("Power Metals" or the "Company") (TSXV: PWM) (FRANKFURT: OAA1) (OTCQB: PWRMF) is pleased to announce an update on Metallurgical test work for the Case Lake Cesium Project ("Case Lake") with the confirmation of high-grade spodumene and tantalite concentrates. The latest test work affirms confirms Case Lake as a multi-element project, capable of production high-grade mineral concentrates of cesium (Refer to press releases announced November 19, 2024, December 03, 2024, and April 14, 2025), alongside tantalum and lithium. Demonstrating the ability to deliver three high-grade critical minerals from the West Joe resource further cements Case Lake's position as a world-class asset in Ontario, Canada. Haydn Daxter, CEO of Power Metals commented: "The recent metallurgical test work confirms Case Lake's ability to produce three high-grade concentrate minerals – cesium, tantalum and lithium – setting it apart from many other projects in North America. With production targeted for 2026, Case Lake is the fourth largest hard rock cesium resource globally that we remained focus on advancing within an efficient timeframe to unlock its full commercial value. Johnathan More, Chairman of Power Metals commented: "I am very pleased with the latest metallurgical test work results from Case Lake. The project continues to stand out as a leading multi-asset in Ontario, with strong potential across all three minerals. This latest round of work further strengthens our position as we continue to de-risk and demonstrate the projects capabilities to deliver the world's fourth hard rock cesium project. Metallurgical Test Work The Company is pleased to report positive metallurgical results from Dense Media Separation (DMS) and Flotation tests on lithium along, with Wet Table (WT) and Magnetic Separation (MS) tests on tantalum from the Case Lake deposit. The test work produced lithium (Li₂O) concentrates with grades as high as 7.70%, and low deleterious Iron (Fe₂O₃) content below 0.66%. Tantalum (Ta) concentrates returned grades as high as 12,508ppm (1.25%). The Company engaged 'Nagrom the Mineral Processor' in Perth, Western Australia to carry out bench-scale test work on representative material from Case Lake. This program utilised DMS and Flotation techniques to concentrate spodumene ore, and WT and MS techniques to concentrate tantalum ore sourced from the West Joe deposit at Case Lake. The results were subject to an independent review and interpretation by SGS Lakefield, a team with significant expertise in mineral processing and metallurgy in Canada. The primary objective of this program was to evaluate the effectiveness of conducting DMS and Flotation on spodumene, along with WT and MS on Tantalum from the waste material produced during cesium concentrate production. Samples 24-036-02W and 24-036-03W were produced as final rejects of 2024 phase I ore sorting testwork that Power Metals completed with Tomra Australia (see press release dated December 3, 2024). Metallurgical results of the DMS and Flotation tests conducted on the West Joe deposit at Case Lake, produced quality concentrates surpassing the current market standards (5.5% Li₂O and <1.2 % Fe₂O₃). Outstanding results returned included, Li₂O grades reaching as high as 7.70%, and low deleterious Iron (Fe₂O₃) grades of sub 0.66%. Wet Table (WT) test results from the West Joe deposit at Case Lake, yielded high-quality Tantalum concentrates of 12,508ppm (1.25% Ta). These initial results are very encouraging and mark a successful first step in confirming the deposit's tantalum potential. Primary samples from the West Joe deposit confirmed Cesium-Tantalum-Lithium mineralization, with samples 24-036-02W and 24-036-03W containing spodumene, tantalite and pollucite. These samples have ore-grade lithium and tantalum, and relatively low cesium. Pollucite was sorted as the primary product during Phase I of the ore sorting process. Sample 24-036-02W was processed to produce spodumene concentrate through DMS and Flotation, demonstrating effective lithium recovery. Sample 24-036-03W yielded tantalite concentrate using WT (gravity) and MS methods, successfully recovering tantalum from the feed sample. Sample 24-036-02W was stage crushed to 100% passing 5.6 mm and wet screened at 0.71mm before DMS test was completed at SG 2.75. Two sighter float tests were conducted on a composite sample that consisted of the product (underflow) of the DMS and the remaining fine material (-0.71mm) from the wet screen. Further wet screening at 0.025 mm and magnetic separation were completed before the composite sample was run through flotation testwork. The DMS plus Flotation test work produced exceptionally high-grade spodumene concentrate with 7.20% Li₂O and recovered 78.8% the lithium (Table 1). Individual sighter float tests showed recoveries of 80% to 99.7%, producing concentrates with 6.4% to 7.7% Li₂O (Figure 3). The pre-flotation DMS concentrate also produced quality spodumene concentrate with 5.24% Li2O and recovered 85.8% of the lithium (Table 2). Both the DMS and DMS plus flotation concentrates have very low iron content at 0.54% and 0.65% Fe2O3. The DMS concentrate contains relatively high cesium (0.88% Cs2O), indicating potential additional by-product credits for the company. The lithium and tantalum beneficiation testwork completed on the final reject (waste) samples from the Companies 2024 Phase I ore sorting successfully demonstrated that the waste products from pollucite sorting at West Joe are amenable to known spodumene and tantalite processing methods. The results further validate that the waste products of the pollucite ore sorting process from West Joe and similar lithium-tantalum plus low-grade cesium mineralized pegmatites at Main Zone can be processed using a low-cost small scale DMS plant. Table 2 – Summary Results for Spodumene Concentrate Produced by DMS Sample 24-036-03W was used to produce tantalite concentrate through gravity-based wet table and magnetic separation tests. The sample was stage-crushed to 100% passing 1mm and wet-screened at 0.075, 0.125 and 0.5 mm to create four sub-samples for wet table testing. Following the initial wet table tests, a composite sample was created from the first two cuts of each sub-sample. This composite then underwent a second round of wet tabling testing, followed by magnetic separation testwork. The test program successfully produced tantalite concentrate grading 12,508 ppm (1.25% Ta), with a recovery rate of 45% (see Table 3). Table 3 – Mass Balance for Tantalite Concentrate Case Lake Property The Case Lake Property is located 80 km east of Cochrane in northeastern Ontario, near the Ontario Quebec border.

POWER METALS UNVEILS TWO NEW TARGET ZONES AT CASE LAKE CESIUM PROJECT
The Company's enhanced structural model defines a new Cesium Triangle Zone ("CTZ") at Case Lake, revealing three folded target zones for exploration West Joe and Main Zone are located in the central fold, with 2 new fold zones located in the southeast and northwest region of the CTZ Geochemical data confirm highly evolved pegmatites in the southern Case Lake trend, indicating potential for high-grade cesium mineralisation Resource expansion to target 17 high priority zones for potential pollucite-bearing pegmatite mineralization A total of 73 targets identified within the CTZ, covering pegmatite dykes, outcrops and structural targets across 37 square kilometers Exploration work underway to define targets, with soil sampling and drilling to follow VANCOUVER, BC, June 10, 2025 /CNW/ - Power Metals Corp ("Power Metals" or the "Company") (TSX VENTURE: PWM) (FRANKFURT: OAA1) (OTCQB: PWRMF) is pleased to announce an updated structural and geochemical model, featuring the new Cesium Triangle Zone ("CTZ") and outlines exploration plans for the Case Lake Cesium Project ("Case Lake") in northeastern Ontario. The CTZ is in the southern region of the property, between tonalite-granodiorites of the Case Lake Batholith and Steele meta volcano-sedimentary units, spanning a 10 km long and 5 km wide area covering 37 square kilometres (Figure 1). The CTZ includes three recurring fold trends with distinct mineralization signatures from elevated geochemistry for fertile cesium, tantalum and lithium. Current mineralization trends from east to west across the three zones. Haydn Daxter, CEO of Power Metals commented: "I am very pleased with the structural work completed to date at Case Lake in collaboration with some of the industry's most respected experts in structural geology, geophysics and geochemistry. These efforts have provided a clearer picture of the project's geological history and identified both current and new target zones that position the Company to unlock the property's full potential. We have now finalised our exploration and targeting program for the next 12 months and anticipate commencing this work in the near future, following the completion of our Maiden Resource Estimate. We look forward to advancing the Case Lake project, building on the strength of our initial resource and driving growth as we look to fast-track towards development. Johnathan More, Chairman of Power Metals commented: The continued development and potential of the Case Lake project is truly exceptional. Our team has not only delivered a robust group of exploration targets but also refined the geological model that underpins our growth strategy. I am particularly encouraged by the identification of two new zones, further strengthening our position as we develop the world's fourth hard rock cesium project in Ontario, Canada. The CTZ contains three structural corridors: southeast, central, and northwest. The central corridor contains cesium-lithium-tantalum mineralization at the West Joe and Main Zone deposits, as well as Northeast and Dome Nine occurrences. The recently identified southeast and northwest corridors offer additional targets in cesium, tantalum, and lithium mineralization. The area features strong deformation in southwest-northeast structural corridors, with magnetite-destructive dilatational zones and folded antiforms that trap cesium-bearing pegmatites. The CTZ includes highly fractionated pegmatites with geochemical signatures indicating cesium fertility, stretching from Dome Nine to West Joe over approximately 10 kms (Figure 2). The updated geological model (geophysics, geochemistry, and structural geology), based on high-resolution airborne, drone-based magnetic surveys, geological and geochemical data from 2017 to 2024, indicates that the south-central part of Case Lake property, known as the Cesium Triangle Zone (CTZ), represents the most fertile region for cesium, tantalum and lithium mineralization (Figure 3). Detailed structural and geochemical analysis has produced 73 exploration targets that will be tested with a series of soil sampling programs to continue to develop a robust geochemical data set, along with exploration drill programs, and cesium resource expansion throughout 2025 and into 2026. In addition, the Company is in the process of initiating field exploration programs at Case Lake that will focus on: Geological mapping and prospecting of priority areas and outcrops identified from target generative work completed by industry leading consultants the company engaged throughout 2024 Soil surveys on a series of grids that cover underexplored areas throughout the CTZ, focusing on samples from topsoil (B-horizon). The company will utilize a multi (66) element Enzyme-Leach geochemical method that was successful in identifying cesium targets south and north of West Joe in 2024 (Figure 4) High-resolution ground resistivity targeting silica-rich pegmatite zones Case Lake Property The Case Lake Property is located 80 km east of Cochrane, northeastern Ontario close to the Ontario - Quebec border. The Property consists of 586 cell claims in Steele, Case, Scapa, Pliny, Abbotsford and Challies townships, Larder Lake Mining Division. The Property is 10km by 9.5km in size with 14 granitic domes.

Power Metals have completed several exploration campaigns that have led to the discovery and expansion of new and historic spodumene bearing LCT pegmatites at Case Lake. The Company has drilled a total of 23,976 meters of core between 2017 and 2024 at the Property. The Case Lake Property is owned 100% by Power Metals Corp. A National Instrument 43-101 Technical Report has been prepared on Case Lake Property and filed on July 18, 2017 (Figure 5). Decelles Property The Decelles Property contains 247 claims, covering 14,229 hectares of LCT prospective ground near the mining centres of Val-dÓr and Rouyn-Noranda, approximately 600km from Montreal. Power Metals acquired the Decelles and Mazerac properties from Winsome Resources in 2023 in a deal that allowed Winsome to increase its stake to 19.59% (Refer to press release announced on August 24, 2023), the transaction remains subject to TSXV approval. The geology of Decelles property is part of the Archean Pontiac sub-province where S-type LCT prospective, pegmatite bearing, granitic Decelles Batholith intrudes into metasedimentary units of the Pontiac Group. Spodumene and Beryl bearing pegmatites have been reported historically within the Pontiac sub-province in association with S-type garnet-muscovite granite. The Decelles property is adjacent to Vision Lithium's Cadillac property where discovery of high-grade lithium pegmatites was reported in 2022 (Figure 5). Mazerac Property The Mazerac Property is located approximately 30 km east of Power Metals' Decelles property near well-established mining camps in the Abitibi region of Canada and is accessible by network of mining-grade forestry roads. The Mazerac property contains 115 claims that cover 6,653 hectares of LCT prospective ground near the mining centre of Val-dÓr and Rouyn-Noranda. The regional geology of Mazerac is similar to Decelles where S-type LCT prospective, pegmatite bearing, granites of Decelles Batholith intrude into metasedimentary units of the Pontiac Group. Spodumene and Beryl bearing pegmatites have been reported historically within the Pontiac sub-province in association with S-type garnet-muscovite granite (Figure 5). Pollucite and Cesium Pollucite is a rare mineral that hosts high grade cesium and is associated with highly fractionated, rare element pegmatites. The main source of cesium known globally is pollucite (Cs,Na)₂(Al₂Si₄O₁₂)•2H₂O, ( Currently the Tanco mine in Manitoba, Canada is the only operating cesium deposit and holds over 60% of the known reserves globally.

MAIDEN MINERAL RESOURCE ESTIMATE CONFIRMS CASE LAKE AS THE WORLD'S FOURTH LARGEST CESIUM RESOURCE
Major Highlights The maiden Inferred Mineral Resource Estimate (MRE) of 13,000 tonnes grading 2.40% Cs₂O at the West Joe dykes within the Case Lake Cesium Project represents the world's fourth only hard-rock cesium resource¹ Additional exploration target of 11,000-15,000 tonnes of Cs₂O identified at the West Joe dykes 17 untested targets with pollucite-bearing pegmatite dykes, outside of the West Joe dykes and within the Case Lake Cesium Project, offer excellent potential to expand the resource profile The MRE covers just one of eight pollucite-bearing pegmatite dykes, based on 7,264 m of drilling from 113 drill holes conducted in 2018, 2022, and 2024 Excellent infrastructure access in the Timmins-Cochrane region of the Abitibi, with existing forestry trails, proximity to rail at Cochrane, powerlines, and major ports in Montreal for export to key markets The MRE establishes the Case Lake Cesium Project as a globally significant cesium source and will underpin its continued development Strategically located in North America, the project supports critical mineral security and aligns with growing global demand VANCOUVER, BC, June 5, 2025 /CNW/ - Power Metals Corp ("Power Metals" or the "Company") (TSX VENTURE: PWM) (FRANKFURT: OAA1) (OTCQB: PWRMF) is pleased to announce the maiden National Instrument 43-101 ("NI 43-101") compliant Mineral Resource Estimate ("MRE") for the Case Lake Cesium Project ("Case Lake"), located in northeastern Ontario. The consolidated in-pit MRE, reported in the Inferred category, comprises 13,000 tonnes grading 2.40% Cs₂O for 330 tonnes of Cs₂O concentrate. This MRE covers just one of eight pollucite-bearing pegmatite dykes within the Case Lake property (Figure 1), based on 7,264 m of drilling from 113 holes completed in 2018, 2022, and 2024. Additionally, an exploration target was produced by Snowden Optiro of 11,000-15,000 tonnes of Cs₂O has been identified at the West Joe dykes, and 17 untested targets including the 8 dykes across 21 km² highlight substantial potential for future resource expansion. ¹ Globally there has been 3 previous hard rock cesium mines with Tanco in Manitoba (Canada), Bikita in Zimbabwe (Africa), and Sinclair in Norseman (Western Australia). Operations commenced at Tanco in the 1950's and has been under Chinese ownership (Sinomine) since 2021. No MRE has been released on the TSX for the Tanco property. Bakita is a privately held property and linked to Sinomine, various reports based on lithium resources have been noted with no MRE relating to cesium oxide. Pioneer Resources produced an updated MRE for Sinclair in November 2018, and initial MRE on March 22, 2017. Haydn Daxter, CEO of Power Metals commented: The announcement of Power Metals first NI 43-101 Mineral Resource Estimate for the Case Lake Cesium Project signals a significant milestone for the Company and Ontario in the development of critical minerals in Canada. With the estimated 13,000 tonnes at a grade of 2.40% Cs₂O based on only 7,264m of drilling, the Case Lake Project is the world's fourth hard-rock cesium deposit. The majority of the pollucite bearing pegmatites remain unconstrained and open to an exceptional potential of further growth as represented with the current exploration target at West Joe. Johnathan More, Chairman of Power Metals, added, I am very pleased to see the team deliver on our maiden Mineral Resource Estimate at Case Lake as we continue to develop this fast-tracked critical mineral project. Our ability to position Case Lake as the world's fourth only cesium resource from 7,264m of exploration drilling is incredibly rare, and further highlights the growth potential with the current exploration target and untested zones on the property. The Company currently is developing the Case Lake Cesium Project to be Ontario's first critical minerals project in production. To achieve this target, we engaged in the MRE at the infancy of exploration drilling to target cesium and look forward to the growth that remains in the property for the Company and the state of Ontario.

Lithium (spodumene) is undergoing a low-cost dense media separation ("DMS"), flotation circuit and magnetic separation analysis at present. Tantalite is concurrently under analysis via wet screen and magnetic separation to review the viability with Nagrom ("The Mineral Processors"), Perth, Australia. The lithium and tantalite test work results are expected in July of 2025.

The potential quantity and grade are conceptual in nature, and there has been insufficient exploration to define a mineral resource. It is uncertain whether further exploration will result in the target being delineated as a mineral resource. Case Lake Cesium Project Mineral Resource Estimate Notes: The Mineral Resource Estimate (MRE) was estimated by Susan Havlin, BSc (Hons), MAusIMM (CP) and reviewed by Dr Andrew Scogings MAIG (RPGEO industrial minerals) of Snowden Optiro, an independent Qualified Person as defined by NI 43-101. Susan Havlin conducted a site visit to Case Lakes in April 2025. The classification of the current MRE into Inferred mineral resources is consistent with current 2014 CIM Definition Standards for Mineral Resources and Mineral Reserves. The effective date for the Mineral Resource estimate is May 30, 2025. All figures are rounded to reflect the relative accuracy of the estimate and numbers may not add due to rounding. The mineral resource is presented undiluted and in situ, constrained by continuous 3D wireframe models, and are considered to have reasonable prospects for eventual economic extraction. Mineral resources which are not mineral reserves do not have demonstrated economic viability. An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that most Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration. The CLCP MRE is based on a validated database which includes data from 113 surface diamond drill holes totalling 7,264 m. The resource database totals 2,499 assay intervals representing 2,541 m of drilling. The average assay sample length is 1.02 m. The MRE is based on a three-dimensional ("3D") pegmatite resource model, constructed in Leapfrog, representing the West Joe pegmatite deposit. Cs₂O grades were estimated for each mineralization domain using 1.0 metre composites. To generate grade within the parent blocks, ordinary kriged (OK) interpolation method was used. The parent block size of 2 mX by 2 mY by 2 mZ with sub-blocking down to 0.5 m in each direction. Dynamic anisotropy was utilised to account for the undulating nature of the pegmatites. Three search passes were employed with an initial search distance half the variogram range, the second search was the range of the variogram, and the final search was double the variogram range. The first search pass had a minimum of eight samples and max of 12 samples, the second pass the minimum dropped to six and for the third search pass the minimum dropped to four samples. Average density values were calculated within the pegmatite with the formula density = 2.665 + (0.008793*Cs2O%) + (0.066436*Li2O%) and assigned in the waste domains based on a database of 1,072 samples. Power Metals envisions that the CLCP deposit may be mined using open-pit mining methods. Mineral resources are reported at a base case cut-off grade of 0.10% Cs₂O. The in-pit Mineral Resource grade blocks are quantified above the base case cut-off grades, above the constraining pit shell, below topography, and within the constraining mineralized domains (the constraining volumes). The results from the pit optimization are used solely for the purpose of testing the "reasonable prospects for economic extraction" by an open pit and do not represent an attempt to estimate mineral reserves. There are no mineral reserves on the Property. The results are used as a guide to assist in the preparation of a Mineral Resource statement and to select an appropriate resource reporting cut-off grade. The exploration target at the CLCP was based on limited deep drilling completed in 2023 and 2024, the pegmatite and mineralization were extended at depth. The target range is conceptual in nature and was generated using assumptions based on the geological and grade continuity of mineralized pegmatites observed from shallow drilling up dip. The base-case Cs₂O Cut-off grade considers the following assumptions: a cesium concentrate (15-20% Cs₂O) price of US$35,000/t, a mining cost of US$7.30/t mined, processing, treatment, refining, G&A and transportation cost of USD$28.09/t of mineralized material, as were pit slope angles of 45° and mining loss and dilution of 5% and 5%. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.

Lithium Royalty Corp. Congratulates Power Metals on World-Scale Cesium Discovery; Potential Near-Term Incremental Revenue Source for LRC
Article content TORONTO — Lithium Royalty Corp. (TSX: LIRC) ('LRC') is pleased to congratulate Power Metals Corp. ('Power Metals') on its maiden mineral resource estimate ('MRE') for the West Joe Dyke within the Case Lake property in Ontario. Article content The MRE establishes the Case Lake property as the fourth major cesium asset in the world, after the Tanco mine in Canada, the Bikita mine in Zimbabwe and the Sinclair mine in Australia. The MRE consists of 13,000 tonnes inferred mineral resource at 2.4% cesium oxide (Cs 2 O), with a cut-off grade of 0.1% Cs 2 O. Power Metals has noted the potential for additional tonnage growth at the Case Lake property, given that its MRE covers the West Joe Dyke. Power Metals highlighted additional exploration targets of 11,000-15,000 tonnes identified at the West Joe Dykes and 17 untested targets at the property. The MRE is based on 7,264 meters of drilling from 113 drill holes conducted in 2018, 2022, and 2024 highlighting the efficacy of its prior drill campaigns. Article content Article content The Case Lake property is one of several properties within the LRC portfolio that have the potential to generate revenue from deposits other than lithium. Other properties with cesium exposure within the portfolio include Grid Metals Corp.'s Donner Lake project in Manitoba and Winsome Resources' Sirmac-Clapier project in Québec. Article content 'The latest Power Metals mineral resource estimate underscores the substantial optionality embedded within our 35-royalty strong portfolio. While lithium is the core focus of our investment philosophy, several of our portfolio companies have multiple commodities on their property that are covered by our royalty agreements. The discovery at Case Lake uncovers additional value for both Power Metals and LRC shareholders, with the potential for additional revenue from the property as soon as next year,' said Ernie Ortiz, President and CEO of LRC. Article content 'With the partial sale of our Tres Quebradas royalty, uncovering value from our cesium exposure, and additional assets that are expected to enter production in the near term, we are optimistic on the path forward for Lithium Royalty Corp.' Article content Cesium is a high-value, critical mineral with only two known current producers globally – the Tanco mine in Canada and the Bikita mine in Zimbabwe – and one prior producer at the Sinclair mine in Western Australia. Annual global cesium production is very limited. The Tanco mine in Canada is the only known source that is still processing cesium ore, and most projects around the world that are prospective for cesium remain in early exploration. This fragile and concentrated supply chain underscores the strategic significance of new cesium discoveries. Cesium applications include advanced electronics, energy, aerospace, and defense systems. Due to its scarcity and growing demand, cesium pricing has surged recently, with cesium carbonate prices trading at approximately US$118,000/tonne according to Shanghai Metals Market (SMM). Article content 2 Article content O with a cut-off grade of 0.1% Cs Article content 2 Article content O, making the property one of the largest cesium discoveries globally. LRC holds a 2.0% gross revenue royalty on all products extracted and sold from the Case Lake property. Other key highlights of the project: Article content Simple Production Process: Power Metals has outlined a production process that minimizes complexity. Power Metals envisions a simple quarry-type operation, that involves extracting the ore, crushing, grinding, screening, and ore sorting, to produce a high-grade concentrate with cesium oxide values between 5-20%. Power Metals' proposed operation does not require any chemical processing and generates limited tailings. The tailings are also likely high value, as they potentially include tantalum and lithium ore. Swift Path to Production: Power Metals believes the project will be fast-tracked to production, with first production anticipated in 2026. Based on a simple production process, Power Metals would only require a provincial environmental permit, for which baseline studies were commenced in 2024. Additionally, the high-grade nature of the ore body and simple process allows for a project with low capital intensity. Strategic Location with Infrastructure Advantages: The project benefits from excellent infrastructure access in the Timmins-Cochrane region of the Abitibi, including proximity to existing forestry roads, rail connections at Cochrane, and nearby powerlines. Its location enables efficient transport to major ports in Montreal, supporting future export to international markets. Positioned in a key North American mining hub, the project advances critical mineral security and is well-aligned with global demand trends. Cesium, the project's primary commodity, is designated a critical mineral by both the United States and Canadian governments, underscoring its strategic importance and scarcity. Article content Other assets with cesium exposure in the LRC portfolio include: Article content announced Article content that surface sampling at its Sirmac-Clapier project in Québec returned high-grade cesium results, including intercepts of up to 5.44% and 2.92% Cs₂O. Geochemical analysis confirmed that the mineralization is likely hosted in pollucite, a rare cesium-bearing mineral. The pegmatite system at Sirmac is highly fractionated, a key indicator of strong lithium and cesium potential, and supports the presence of extensive mineralizing systems. These findings significantly enhance the potential exploration upside across the broader project area and strengthen Winsome's strategy to delineate a new cesium resource within Canada's critical minerals corridor. LRC holds a 4.0% GOR royalty on all minerals at the Sirmac-Clapier project. Article content Grid Metals Donner Lake Project: Article content Grid Metals Article content announced Article content the completion of 28 diamond drill holes totaling 827 meters at the High-Grade Dyke on its 75%-owned Donner lithium-cesium property in southeastern Manitoba. The drill program was funded by Tantalum Mining Corporation of Canada Limited ('Tanco'), which operates the only cesium processing facility in North America. Under a toll milling agreement, Grid gains access to Tanco's established infrastructure, offering a path to cesium production with lower upfront capital requirements. Grid Metals is now preparing core samples for rare metal assays and mineralogical analysis, to confirm the presence of pollucite, Tanco's preferred feedstock. LRC holds a 2.0% GOR royalty on all minerals on the Donner Lake project. Article content LRC's underwriting assumptions when acquiring its royalties (other than its Horse Creek silica royalty) have been based solely on the lithium potential of each project. The potential for these projects to uncover other minerals – including cesium – is not factored into those assumptions, representing hidden value for LRC shareholders. Article content Cesium Market Overview Article content Cesium is the heaviest stable alkali metal and deemed a critical mineral by the United States, Canada and several other countries. Similar to lithium, it has a unique set of characteristics due to its position on the periodic table. Cesium has excellent photoelectric properties, strong chemical activity and is a high-quality material for infrared technology applications. Its low ionization energy allows it to easily donate an electron, efficient for ion propulsion and photoelectric devices. High atomic mass and resonance frequency stability make it ideal for atomic clocks, making it an international standard. Its low melting point of 28.5°C is useful for heat transfer, high reactivity for energy transfer and non-corrosive, safe drilling fluid. Article content Cesium primarily will come from pollucite ore, in the form cesium oxide. It is then refined down into several other forms for specific applications. The main forms of cesium are cesium formate and cesium fines – including cesium carbonate, cesium chloride and cesium nitrate. Historically, the largest demand has been for cesium formate, a drilling fluid used in high pressure and high temperature oil and gas exploration. The product is typically rented by oil and gas exploration clients. After completion of the well, the used brine is returned and reprocessed for subsequent drilling operations. It is estimated that 10,000 tonnes of cesium formate exist globally, with approximately 5% getting depleted and replaced annually. Article content Cesium fines are a small but specialized market, with developing applications in energy, communication, medical and defense. Applications include: Article content The market for cesium fines was estimated by USGS to be ~2,200 tonnes in 2024, with an additional 500 tonnes of demand from cesium formate replacement. According to USGS, no primary production of cesium exists, except small quantities in China. Existing stockpiles at former mine sites feed downstream refineries, though recent reports have indicated that stockpiles may be depleted within a few years. Article content About Lithium Royalty Corp. Article content LRC is a lithium-focused royalty company organized in Canada, which has established a globally diversified portfolio of 35 revenue royalties on mineral properties that are related to the electrification and decarbonization of the global economy. The Company's royalty portfolio is focused on the battery supply chain for the transportation and energy storage industries and is underpinned by mineral properties that produce or are expected to produce lithium and other battery materials.
