Power Metals Corp. reported high-grade cesium and lithium results from the first round of exploration drillhole assays received from the winter 2024 drill program at its 100% owned Case Lake property in northeastern Ontario. Exploration drilling outside of known target areas has intersected shallow high-grade cesium mineralization up to 18.13% hosted in pollucite, and spodumene mineralization in the first five (5) drill holes of thirty-two (32) completed drill holes at West Joe.

The West Joe deposit is a unique, highly fractionated LCT pegmatite system that contains world-class high-grade cesium (Cs2O) mineralization hosted in pollucite (Figure 1). It is characterized by two stacked pegmatites that are up to 9 meters thick and contain high grade Lithium ? Cesium ?

Tantalum mineralization, extending for 100 meters along strike and open down plunge. The deposit was discovered by Power Metals in 2018 with high grade cesium up to 24% reported during drill programs completed in 2018 and 2022. High-grade cesium mineralization at West Joe occurs at the far west end of a 10 km mineralization trend at Case Lake that extends from Dome 9 to the far northeast through to West Joe in the west.

The 2024 drilling at West Joe (holes PWM-24-171 to PWM-24-202) is targeting high grade cesium in pollucite, spodumene, and tantalite-columbite mineralization that occurs in and around contact between Case Lake Batholith and metasedimentary units. Several step out exploration holes were drilled to test exploration targets along strike and down dip of the West Joe deposit in line with the current geological model. The first five exploration drill holes as reported in this announcement highlight the continuation of a world-class, high-grade cesium zone at West Joe with broad lower grade cesium mineralization along with narrow high grade cesium mineralization of close to pure pollucite.

All holes have intercepted high-grade cesium mineralization in pollucite, and at a very shallow depth that will assist in growing the known mineralized zone to near surface projection. Hole PWM-24-171 intersected 2-meters of 5.60% Cs2O within 9.2 meters of LCT pegmatite that contains 1.27% Li2O, 1.30% Cs2O, and 149 ppm tantalum, extending mineralization up-plunge of drillholes PWM-22-147 and PWM-22-150 (Figure 2 and Table 1). Hole PWM-24-177 intersected shallow high-grade cesium with 6.4 meters of 1.43% Li2O, 5.95% Cs2O, and 311 ppm tantalum, this included 3.7 meters of 10.4% Cs2O from 24 meters.

Within this high-grade zone cesium zone, they defined a 2.0-meter interval of 15.05% Cs2O and a meter of 18.13% Cs2O (Figure 3 and Table 1). Cesium grades this high have only been reported to date in the three known global deposits, Bakita*, Sinclair*, and Tanco. The consistent mineralization from the current and historical drilling at West Joe adds further weight to this developing into a world class deposit.

CASE LAKE MAIN: 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 (Figure 4). The LCT pegmatite system at Case Main is characterized by high-grade Lithium ? Tantalum ± Cesium mineralization that 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. The Case Main pegmatites trend parallel to each other while striking at 245? and dip moderately between 50?

- 70? to the north. The mineralization at Case Main and throughout Case Lake property displays distinct zonation of spodumene, tantalite-columbite, and pollucite, characteristics of highly fractionated LCT pegmatite systems. The North and Main dykes at Case Main are characterized by lithium-rich coarse-grained 2 ?

25 cm spodumene mineralization that makes up to 10 to 30 % of the dykes, whereas the South dyke and several subordinate dykes are characterized by lower-grade lithium and ore-grade tantalum mineralization. Drilling conducted at Case Main during the 2024 program (PWM-24-164 to PWM-24-170) delineated shallow high-grade lithium and tantalum mineralization characterized by coarse-graded spodumene in the Main and North dykes with up to 13.30m @ 1.84% Li2O, PWM-24-167. In addition to this drilling intercepted the presence of several lower grade pegmatites with ore-grade tantalum in the South dyke and sporadic subordinate dykes that confirms the exploration potential for additional mineralization occurring in these dykes .
