PHASE II DRILLING

The current results from Phase II drilling produced strong mineralization with pollucite bearing high-grade cesium, spodumene, and tantalum (LCT) in holes PWM-24-217, and PWM-24-222/225 with the successful intersection of consistent high-grade mineralization. These intercepts further confirm the continuation of the West Joe mineralization trend both up and down dip of previously reported drillholes PWM-24-212, PWM-18-112, PWM-24-209, PWM-22-128, and PWM-24-200 (Figures 2-4).  The strong mineralization zones in these drillholes are characterized by intercepts of 1.77% to 4.55% Cs₂O, 0.77% to 2.22% Li₂O, and 339 ppm to 962 ppm Ta in 6.20 to 8.45 meters thick pegmatites. The rich core of the mineralization is 3.52 meters thick and on average contains 7.12% Cs₂O, 1.82% Li₂O, and 865 ppm Ta. In addition to the strong cesium mineralization, PWM-24-217 hosts shallow (16.5 to 18 meters down hole) lithium and tantalum mineralization with individual high-grade samples running 3.01% to 4.57 % Li₂O and 1487 to 5328 ppm Ta. Similar shallow high-grade cesium mineralization was encountered at 10.00 to 23.80 meters down drillholes PWM-24-222/225 with multiple individual samples reporting 13.58 % Cs₂O on average.

Drillhole PWM-24-220 intersected strong lithium and tantalum mineralization that averages 1.15% Li₂O and 226 ppm Ta over three meters. Drillhole PWM-24-221 intersected strong lithium-tantalum and low-grade cesium mineralization that averages 1.31% Li₂O, 245 ppm Ta, 0.45% Cs₂O over 8.85 meters, further delineating LCT mineralization up dip of previously reported drillhole PWM-22-150.

Exploration holes PWM-24-215, 216, 219, 228, & 229 that tested structural and geophysical targets did not report significant mineralization. However, all holes intersected LCT pegmatites with anomalous lithium, cesium, and tantalum, confirming the exploration potential of the main structure at West Joe.

The remaining eight (8) drill holes to report from 2024 Phase II are expected in the coming weeks to complete this program, these holes are predominantly regional exploration holes to define the geological structures and lithologies around the broader mineralization zones at the CLP.

2024 PHASE III DRILLING

The Company commenced its 2024 Phase III drilling program over the weekend at the Case Lake Project (CLP) in collaboration with Black Diamond Drilling (Figure 5). Drilling is scheduled to continue through mid-December, focusing on the West Joe and Main Zone targets. Following the completion of this phase, all field activities will be temporarily shut down until early 2025. Sample dispatch to SGS Laboratories is expected to begin later this month and continue into December. Results from the Phase III program are anticipated in late January and will continue through February 2025.

Sampling and QAQC Procedures 

Samples were taken across every pegmatite and 1.5 meter into the barren host rock on either side of dykes. Sample lengths were around 1-metre NQ (48 mm) and HQ (64 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 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.

The Decelles Property contains 669 claims, covering 38,404 hectares of LCT prospective ground near the mining centers of Val-dÓr and Rouyn-Noranda, approximately 600km from Montreal. Power Metals acquired the Decelles and Mazerac properties from Winsome Resources in 2023 in a deal that allowed Winsome to increase its stake to 19.59% (Refer to press release announced on August 24, 2023). The geology of Decelles property is part of the Archean Pontiac sub-province where S-type LCT prospective, pegmatite bearing, granitic Decelles Batholith intrudes into metasedimentary units of the Pontiac Group. Spodumene and Beryl bearing pegmatites have been reported historically within the Pontiac sub-province in association with S-type garnet-muscovite granite. The Decelles property is adjacent to Vision Lithium’s Cadillac property where discovery of high-grade lithium pegmatites was reported in 2022 (Figure 6).

Mazerac Property

The Mazerac Property is located approximately 30 km east of Power Metals’ Decelles property near well-established mining camps in the Abitibi region of Canada and is accessible by network of mining-grade forestry roads. The Mazerac property contains 259 claims that cover 14,700 hectares of LCT prospective ground near the mining center of Val-dÓr and Rouyn-Noranda. The regional geology of Mazerac is similar to Decelles where S-type LCT prospective, pegmatite bearing, granites of Decelles Batholith intrude into metasedimentary units of the Pontiac Group. Spodumene and Beryl bearing pegmatites have been reported historically within the Pontiac sub-province in association with S-type garnet-muscovite granite (Figure 6).

Pollucite and Cesium

Pollucite is a rare mineral that hosts high grade cesium and is associated with highly fractionated, rare element pegmatites. The main source of cesium known globally is pollucite (Cs,Na)₂(Al₂Si₄O₁₂)•2H₂O, (https://www.gov.mb.ca/iem/geo/industrial/pollucite.html). Currently the Tanco mine in Manitoba, Canada is the only operating cesium deposit and holds over 60% of the known reserves globally.
