PMET Resources Inc. Demonstrates Greater Than 97% Caesium Extraction From Pollucite Concentrate PMET Resources Inc. provided an update on two parallel bench-scale testwork programs focused on caesium (Cs) extraction from pollucite samples from the Shaakichiuwaanaan Project. Leaching of pollucite concentrate using sulphuric acid was highly successful with greater than 97% recovery of the caesium (Cs) into solution achieved. Bench-scale testwork on impurity removal was also successful, demonstrating efficient removal of key impurities such as aluminum. Opportunity identified to potentially recover a rubidium by-product. Primary objective of program was fully realized – that being to identify a preliminary set of conditions to extract caesium from pollucite concentrate (produced from the Vega Zone) at high recovery while characterizing (and limiting) the impurity profile. Next steps will build upon this extraction phase of work with a primary objective to produce gram quantities of high-purity Cs-sulphate, Cs-carbonate, Cs-formate, and potentially Rb-carbonate. PMET is working with Koch Technology Solutions, part of Koch Inc., evaluating advanced processing pathways to value-added caesium products. Preliminary results from Phase 1 indicate both synthetic and live Pregnant Leaching Solution yield very selective high loading factors of caesium recovery using Koch's proprietary flow sheet. The bench-scale test program being advanced by Koch Technology Solutions is designed to assess the application of their proprietary flowsheet technology, to produce a range of value-added caesium chemical compounds. Approximately 6 kg of pollucite concentrate is being used to support the testwork. Preliminary results from Phase 1 of the program indicate a strong and selective caesium recovery. The testwork will now move onto Phase 2 and the company anticipates expanding the mandate to produce gram quantities of caesium derivative products as a complete bench-scale proof-of-concept. Next steps will build upon this bench-scale testwork with a primary proof-of-concept objective to produce gram quantity samples of high-purity Cs-sulphate, Cs-carbonate, Cs-formate, and potentially Rb-carbonate. This test program is currently underway at SGS Canada's facility in Lakefield, Ontario, with results expected circa Fourth Quarter 2026. The CV13 Pegmatite, host to the caesium Mineral Resource, is located 97% Cs recovery is with respect to the pollucite concentrate feed through to initial impurity removal. Pollucite concentrate (~12% Cs2O) produced from prior XRT ore sorting program, of which a portion was used as feed for the bench-scale caesium extraction and recovery program at SGS Canada and Koch Technology Solutions discussed herein. The property also hosts the world's largest in-situ pollucite-hosted caesium pegmatite Mineral Resource, comprising 0.69 Mt at 4.40% Cs2O (Indicated) and 1.70 Mt at 2.40% Cs2O (Inferred). The testwork used XRT ore sorting to produce concentrates of 11.5% Cs2O and 20.0% Cs2O at an overall 88% recovery. The company has demonstrated efficient extraction of caesium from pollucite concentrates (12% Cs2O) with greater than 97% recovery. Announcement • Jun 15
PMET Resources Inc. Completes Concept Study Evaluating Processing Spodumene Concentrate Into Battery-Grade Lithium Carbonate At Shaakichiuwaanaan Site PMET Resources Inc. completed a concept study evaluating future potential to process spodumene concentrate into a value-added lithium product, directly at the Shaakichiuwaanaan site. Following a structured review of seven processing flowsheet options to produce a value added lithium product, the study identified Primero's proprietary ALi® atmospheric leach process as the preferred value-added pathway for further study, given its overall economic potential, strong logistics efficiency benefits and technical risk profile, and its alignment with the Company's sustainability objectives through practicing environmental care in processing and minimizing the Project's environmental footprint. Bench scale testwork on Shaakichiuwaanaan spodumene concentrate samples has been undertaken by Primero in Perth - Western Australia using the ALi® process, producing a 99.8% Li2CO3 battery-grade lithium carbonate. If combined with the use of electric calcination through Québec's low-cost renewable energy, on-site value-added processing has future potential to reduce carbon intensity and improve efficiencies within the battery materials supply chain. The On-Site Refining Strategy is a staged, longer term, growth opportunity and is not required for the current proposed development of the base spodumene concentrate project outlined in the 2025 Feasibility Study. Next steps - future work expected to determine how to capture further economic benefits of value-added products at site including potential introduction of electrical calcination technology to leverage the full potential of Québec's renewable and low-cost hydroelectric power. The Project's 2025 Feasibility Study base case has already demonstrated the resource scale and grade that contributes to the low-cost of a spodumene concentrate produced at Shaakichiuwaanaan. The Project also benefits from being adjacent to some of the lowest-cost renewable hydroelectric power in North America. As part of its stated growth and diversification strategy to further add value to the Project, the Company has now completed a Concept Study assessing the potential to process spodumene concentrate into higher-value lithium chemical products directly at site. The work forms part of the Company's broader long-term growth strategy to capture the potential additional value within the lithium supply chain while establishing a lower-carbon, Western-facing lithium chemicals platform in Québec. The Concept Study is based on low-level economic and technical assessments that are not sufficient to support the Company publishing production targets and economic outcomes or to provide assurance of an economic development case. The Concept Study does not constitute a preliminary economic assessment, pre-feasibility study, or feasibility study as defined under NI 43-101. A Potential redefinition of the North American Lithium Chemicals Supply. The Company believes the Shaakichiuwaanaan Project has the potential over its life to support an improved and more efficient lithium chemicals supply chain model, leveraging Québec's abundant low-cost renewable hydroelectric power, strategic location within North America and proximity to key European and North American markets. Spodumene concentrate produced at Shaakichiuwaanaan is expected to be a raw material feed for a high-value chemical industry that is, to this day, largely conducted outside of Canada. Producing a more concentrated, value-added lithia product on site is expected to provide the following benefits: Redefine the lithium value chain model by locating electric calcination and some or all of the chemical conversion at the mine site, capturing significant logistical benefits by materially reducing shipped volumes and costs through the production of a concentrated higher lithia content product; Leverage Québec's renewable and low-cost hydroelectric power to support a lower-carbon lithium chemical supply chain, with the potential to enhance sustainability and materially reduce logistics-related emissions and fossil-fuel dependence; Creation of a western-facing lithium chemical supply chain, supporting western mineral sovereignty and re-shoring value traditionally retained by downstream spodumene converters outside of Québec and Canada; and Enhance Project value through the transformation of spodumene into a higher lithia content product that has the potential to command higher values and potentially broadening the Project's customer-base. The Company engaged Primero Group to complete a Concept Study to evaluate potential value-added processing routes for the spodumene concentrate produced at the Shaakichiuwaanaan Project. The primary objectives of the Study were to: Reduce the logistics associated with transporting 5.5% Li2O Spodumene Concentrate (SC5.5) over long distances (844 km trucking to Matagami with subsequent 1,075 km rail route to shipping port); Evaluate whether producing an industrial or battery grade lithium chemical could improve market flexibility and project value; and Identify the most technically and economically robust processing route to progress into future study stages. Phase 1 of the Study provided a concept level assessment of seven alternative flowsheets for chemical processing options, with the goal of narrowing down options to progress to a Phase 2 assessment, which focused on detailed refinement of product pathways. Within the Phase 2 assessment, both Acid Roast and Atmospheric Leach options were considered. The Atmospheric Leach option (through Primero's proprietary ALi® process) was found to deliver the strongest overall performance in the areas that most influence long-term Project value.
