Power Metals Corp. Delivers More High-Grade Cesium and Tantalum Results from Case Lake
Power Metals Corp. announced high-grade results from final assays from the Phase III drill program at the 100%-owned Case Lake Project (CLP) in northeastern Ontario. Shallow, high-grade, and consistent mineralization with exceptional cesium oxide (Cs2O) and tantalum (Ta) intercepts were identified at the West Joe prospect, including concentrations of up to 22.70% Cs2O and 6,211ppm Ta. These final assay results from the Company's Phase III drilling campaign continue to reinforce the opportunity to target multi-element resource development at the world-class Case Lake Project. The Company completed a total of 8,028m of exploration drilling across the property during 2024, with the following exceptional results returned from West Joe: PWM-24-242: 8.07m at 5.19% Cs2O, 1438 ppm Ta, and 2.19% Li2O from 10.30m, including 4.70m @ 8.72% Cs2O, 2,435ppm Ta, & 2.50% Li2O from 13.30m, including 1.00m @ 11.70% Cs2O, 208ppm Ta, & 1.85% Li2O from 13.30m, PWM-24-246: 9.95m @ 3.78% Cs2O, 334ppm Ta, and 1.12% Li2O from 11.25m, including 5.55m @ 5.48% Cs2O, 413ppm Ta, & 1.62% Li2O from 11.25m, including 0.75m @ 22.70% Cs2O, 420ppm Ta, & 0.66% Li2O from 15.05m, PWM-24-259: 6.65m @ 3.56% Cs2O, 290 ppm Ta, and 1.15% Li2O from 19.75m, including 5.70m @ 4.14% Cs2O, 311ppm Ta, & 1.03% Li2O from 20.70m, including 1.53m @ 7.56% Cs2O, 474ppm Ta, & 0.77% Li2O from 22.07m, PWM-24-252: 7.95m @ 2.85% Cs2O, 351 ppm Ta, and 1.47% Li2O from 18.35m, including 5.10m @ 3.96% Cs2O, 396ppm Ta, & 1.78% Li2O from 20.20m. including 0.60m @ 13.50% Cs2O, 185ppm Ta, & 2.04% Li2O from 20.20m. Power Metals has received the second round of assay results from its 2024 Phase III exploration campaign, completed at Case Lake with Black Diamond Drilling. The Company drilled a total of 1,475m in 23 diamond drill holes (PWM-24-236 to PWM-24-259) to delineate and extend cesium mineralized zones at the West Joe prospect. The first round of assay results from 12 drillholes, announced in early February 2025, confirmed near-surface high-grade pollucite, tantalite, and spodumene with cesium, tantalum, and spodumene grades up to 20.40% Cs2O, 5,262ppm Ta, and 5.31% Li2O. Assay results from the final 11 drillholes confirmed near-surface high-grade cesium, tantalum, and lithium mineralization, consistent with pollucite (1-25%), tantalite (0.1-1%), and spodumene (1-30%) mineralization, occurring between 5 to 40m depth at West Joe. The second round of reported drillholes intersected strong LCT mineralization in zones from 4.85m to 10.05m wide in fractionated pegmatites with 0.80% to 5.19% Cs2O, 266ppm to 1,438 ppm Ta, and 0.84% to 2.79% Li2O. The core of mineralization in these holes is characterized by 2.00m to 6.80m wide high-grade zones that on average contain 3.63% Cs2O, 552 ppm Ta, and 1.03% Li2O. Drillholes PWM-24-242, PWM-24-246, PWM-24-252, and PWM-24-259 intersected exceptionally high-grade cesium characterized by 7.84% to 22.70% Cs2O in multiple individual samples. All reported drillholes showed strong cesium mineralization and high-grade tantalum and lithium, with samples ranging from 504ppm to 6,211 ppm Ta and 2.41% to 5.85% Li2O, consistent with LCT mineralization in highly fractionated pegmatite systems. Drillholes PWM-24-242, PWM-24-246, PWM-24-248, PWM-24-251, PWM-24-257, and PWM-24-258 reported high-grade tantalum mineralized intervals that grade between 928ppm to 6,211 ppm tantalum. The tantalum rich zone in these holes forms a 4.24m wide high-grade mineralization envelope that averages 3.99% Cs2O, 775 ppm Ta, and 2.21% Li2O. Strong LCT mineralization was intersected in highly evolved pegmatites including: Hole PWM-24-242: 8.70m averaging 5.19% Cs2O in a pollucite-rich zone. Hole PWM-24-246: 9.95m averaging 3.78% Cs2O. Hole PWM-24-259: 6.65m averaging 3.56% Cs2O. Hole PWM-24-252: 7.95m averaging 2.85% Cs2O. Samples were taken across every pegmatite and 1.5m into the barren host rock on either side of dykes. Sample lengths were around 1-meter NQ (48 mm) core diameter, though individual sample length was determined based on internal zoning of the dykes and the locations of their contacts. The sampled core was cut in half with one half being sent for analysis and the other half remaining in the box for reference. All core is stored at Power Metals' core storage facility in Cochrane, Ontario. Each sample was put into its own plastic sample bag with a sample tag and closed with zip ties. About 15% of the samples submitted to SGS Canada ("SGS") for analysis were QAQC samples that were inserted into the sample stream and consist of a high and low-grade lithium, tantalum, and cesium standards, blank material, and duplicates. Samples were dropped at SGS Cochrane, in Ontario. Samples submitted to SGS were prepped, crushed, and pulverized in Sudbury and were subsequently sent to SGS Burnaby and SGS Lakefield for multi element analysis using sodium peroxide fusion ICP-AES/ICP-MS and borate fusion XRF. All cesium results above 1% were analyzed using 4-Acid digest AAS at SGS Lakefield.
