Power Metals Corp. reported high-grade cesium and lithium results on the remainder of exploration drillhole assays from the winter 2024 drill program (the "Program") at its 100% owned Case Lake property (the "Property") in northeastern Ontario. In addition, the assay results at the Main Zone continues to deliver encouraging lithium intercepts with the following highlights: PWM-24-201: 7.13 m at 1.21% Li2O, 6.27% Cs2O and 348 ppm Ta from 14.15 m; Including 5.00 m @ 1.31% Li2O, 8.81% Cs2O and 265 ppm Ta from 15.00 m; Including 1.00 m @ 1.02% Li2O, 19.40% Cs2O and 108 ppm Ta from 17.00 m; PWM-24-198: 3.22 m at 1.76% Li2O, 7.32% Cs2O and 140 ppm Ta from 11.00 m; Including 2.45 m at 2.27% Li2O, 9.29% Cs2O and 156 ppm Ta from 15.55 m; Including 0.80 m @ 0.36% Li2O, 24.70% Cs2O and 9 ppm Ta from 16.20 m; PWM- 24.20 m; PWM -24-199: 8.11 m at 1.42% Li2O, 4.50% Cs2O and 233 ppm Ta from 7.12 m; Including 4.50 m @ 1.42%Li2O, 8.03% Cs2O and 242 ppm Ta from 9.00 m. Including 1.00 m at 1.25% Li2O, 15.90% Cs2O and 102 ppmTa from 11.00 m. PWM-24-189: 8.70 m at 1.74% Li2O, 4.,98% Cs2O and 782 ppm Ta from 14.25 m; Including 5.00m at 1.67% Li2O, 8.,59% Cs2O and 1116 ppm Ta from 16.00 m; Including 1.,00 m at 2.20% Li2O, 20.14% Cs2O and 459 ppm Ta from 18.00 m. PWM -24-202: 7.74 m at 1.82% Li2O, 2.07% Cs2O and 534 ppm Ta from 8.60 m. Including 5.00 m at 1.97% Li2O, 3.13% Cs2O and 670 ppm Ta from 10.00 m. PWM the24-191: 5.32 m at 1.01% Li2O, 2".39% Cs2O and 278 ppm Ta from 41.00 m. Including 2.00 m at 0.61 % Li2O, 6.12% Cs2O and 367 ppmTa from 41.00 m. PWM.

PWM-24-186: 32.44 m at 1.40% Li2O, 0.58% Cs2O and 248 ppm Ta from 10.41 m. Including 1.20 m at 0.62% Li2O, 8". The West Joe deposit is a unique, highly fractionated lithium, cesium, tantalum (LCT) pegmatite system that contains world-class high-grade cesium (Cs2O) mineralization hosted in pollucite, along with high-grade lithium and tantalum. It is characterized by two stacked pegmatites that are up to 9 meters thick and extend for 100 meters along strike and open down plunge.

The 2024 winter drill program at West Joe intersected consistent high-grade cesium mineralization in majority of the holes drilled to define and delineate LCT mineralization at West Joe. Several holes that include PWM-24-189, 198, 199, and 201 intersected high-grade cesium in pollucite between 11.9% to 24.7%. The high-grade cesium is bound by consistent medium-grade cesium mineralization between 2% to 9% (Figures 1-3, Table 1).

In addition to the high-grade cesium and lithium mineralization, high-grade tantalum mineralization was intercepted above 500 ppm tantalum in multiple drillholes. PWM-24-186 was drilled to test consistency of LCT mineralization down dip and plunge of the main dyke at West Joe and confirmed continuity and the widest mineralization at West Joe to date with 32.4 meters of 1.4% Li2O, 0.58% Cs2O, and 248 ppm Ta. Exploration drill holes have expanded mineralization along-strike and down-dip at West Joe intersecting high-grade cesium, lithium, and tantalum in holes PWM-24-175, 176, 185, 187, 191, and 197, indicating an open mineralization system down plunge of West Joe.

Additional step-out exploration holes drilled to the east and west of West Joe did not intersect significant mineralization, however, did intersect pegmatites that contain anomalous ore-grade tantalum mineralization above 100 ppm. Two samples from drill holes PWM-24-179 and 180 drilled 600 meters along strike to the east of West Joe reported 494 and 207 ppm tantalum respectively. LCT pegmatite mineralization at Case Main is represented as a stacked pegmatite system that is part of three main dykes, historically referred as South, Main, and North dykes.

The high grade LCT pegmatite system at Case Main is up to 35 meters thick and extends for more than 400 meters along strike. Mineralization continues to 100 meters vertical depth and remains open down plunge to the west and along strike to the east. PWM-24-169 and 170 were drilled to extend historic cesium and lithium mineralization from drill hole PWM-17-49 that reported 3 meters of 1.61% Li2O, 1.35% Cs2O, and 144 ppm Ta.

PWM-24-169, drilled to the east at Main Zone intersected 4 meters of 0.99% Li2O, 0.4% Cs2O, and 186 ppm of Ta, indicating open mineralization to the east of Main Zone. The 3 meter intercept of LCT mineralization in PWM-24-169 contains 1.1 meters of 1.1% Li2O, 1.03% Cs2O, and 213 ppm of Ta, indicating the potential for cesium mineralization on the south side of the Main dyke at Case Main.
