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.

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.

'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.

'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).

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.

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.

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.

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.
