PMET Resources Inc. (TSX: PMET)(OTCQX: PMETF) — formerly Patriot Battery Metals — has successfully produced high-recovery, commercial-grade pollucite concentrate from its 100%-owned Shaakichiuwaanaan Lithium-Cesium Project in Quebec, confirming that the world’s largest pollucite-hosted cesium deposit can yield a highly marketable critical mineral product using a simple, low-impact process.
The testwork achieved grades up to 20% cesium oxide with 88% recovery through dry XRT ore sorting — a key milestone that establishes a clear pathway for cesium to emerge as a valuable byproduct alongside lithium and tantalum.
The results underscore PMET’s broader strategy of transforming Shaakichiuwaanaan into a cornerstone hub for North America’s critical metals supply chain.
PMET Resources Executive Vice President Exploration Darren L. Smith commented on the successful production of high-recovery, commercial-grade pollucite concentrate from Shaakichiuwaanaan via press release:
“These initial testwork results confirm that Shaakichiuwaanaan’s CV13 Deposit has the potential to deliver highly marketable commercial-grade pollucite concentrates using a relatively simple and cost-effective recovery method – XRT ore sorting. This is an encouraging outcome for this stage of testwork, with strong recoveries and upgrading. Importantly, the reject material from the XRT circuit remains well sized for subsequent spodumene recovery via conventional DMS and tantalite recovery using gravity and magnetic methods, creating a clear pathway to potentially unlocking multiple value streams from the Project.”
Smith continued,
“A follow-up testwork program is being planned which will focus on optimization of the XRT circuit for pollucite recovery as well as subsequent recovery of spodumene and tantalite. The Company is actively exploring approaches and opportunities to unlocking this globally leading cesium opportunity at Shaakichiuwaanaan.”
PMET’s Shaakichiuwaanaan project already hosts the largest lithium pegmatite Indicated resource in the Americas and now the largest pollucite-hosted cesium resource globally — both contained within a single, scalable deposit.
These metals are indispensable to EVs, energy storage, semiconductors, and next-generation solar applications.
And while electric vehicle sentiment in North America has cooled slightly, global EV sales continue to climb to record levels, driven by strong demand in Asia and Europe and underscoring the long-term need for secure, diversified supply of critical metals — particularly lithium.
PMET’s management believes the lithium market has already bottomed and is now approaching a new demand shock — driven not only by surging EV sales globally but by the rapid rise of large-scale energy storage.
At a time when China is tightening its grip on critical-metal exports and openly using that dominance as geopolitical leverage, PMET’s North American jurisdiction, infrastructure, and strategic alliances with major automakers such as Volkswagen’s PowerCo position the company as a future key supplier to Western markets seeking secure, transparent supply chains.
PowerCo has already invested roughly C$69 million for a 9.9% equity stake in PMET, including an offtake agreement for 100,000 tonnes per annum of spodumene concentrate over ten years.
PMET continues to engage with additional downstream players in North America, Europe, and Asia that share the same goal of diversifying supply chains away from China — signaling that the PowerCo partnership may be just the first of several strategic partnerships to come.
Longer term, the company envisions a consortium-style development model, bringing together automakers, battery manufacturers, and government partners to establish a vertically integrated critical-minerals hub in North America.
Next catalysts include completion of a lithium-only Feasibility Study — due in the coming weeks — which will form the foundation for a production decision at Shaakichiuwaanaan.
Separate studies are underway to evaluate the co-product economics of cesium and tantalum, both of which could significantly enhance project value.
With strong grade, scale, and jurisdictional advantage, PMET Resources is advancing one of North America’s most strategically important critical-metal projects and doing so just as global demand enters what could become the next major supply shock.
With testwork ongoing, new co-product studies advancing, and active dialogue across the EV and energy storage industries, PMET is actively positioning to lead the next phase of North America’s critical-minerals buildout.
