2024 EXPLORATION DRILL PROGRAM

 

Exploration results in this news release are the remainder of assays from the outstanding 29 drill holes completed at West Joe and Main Zone from the Company’s winter drill program at Case Lake. A table of all collars, composites, and prospects is displayed in Table 1.

 

Haydn Daxter, Power Metals CEO commented “The results to date from West Joe are incredibly exciting from our winter exploration drilling program that has delivered our highest cesium grades on the property. This unique and complex prospect not only displays world class cesium with 24.70% and also displayed lithium grades up to 3.55% along with tantalum reported at 2201 ppm from recent drilling. These results will continue to build on the potential at the property as we continue our metallurgical test work and prepare for Phase II of drilling this summer”.

 

WEST JOE

 

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 (Figure 1). 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 (Table 1). 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 (Figures 1-3, Table 1). 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.

 

MAIN ZONE

 

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 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 (Figure 4, Table 1). 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.

 

Johnathan More, Chairman of Power Metals commented “We are extremely pleased to see drill assays have added additional high-grade cesium, lithium, and tantalum mineralization at West Joe to this world-class prospect along with producing consistent lithium results from Main Zone. We look forward to our ongoing field activities and commencing our fully funded Phase II drill program in summer at Case Lake.”

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 core diameter (48 mm), 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 Activation Laboratories Ltd. (“Actlabs”) and 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 either Actlabs Timmins or SGS Cochrane, in Ontario. Samples submitted to Actlabs were prepped,  crushed and pulverized in Timmins and were subsequently sent to Actlabs geochemistry laboratory in Ancaster, Ontario for multi element analysis using sodium peroxide fusion ICP-OES/ICP-MS and borate fusion ICP-MS. 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.

 

Actlabs and SGS Canada are independent of the Company.

 

Further to the Company’s news release dated March 28, 2024, the Company announces that the stock options granted to Outside-The-Box will have an expiry date of March 27, 2026.  Otherwise, subject to TSX Venture Exchange approval, all other terms of the options as announced on March 28, 2024, remain in full force and effect.

 

Pursuant to the press release dated August 24, 2023, the Company is continuing to prepare the necessary documents to receive final TSXV approval for the acquisition of the properties, including the preparation of a technical report.

 

Case Lake Property

 

The Case Lake Property is located 80 km east of Cochrane, northeastern Ontario close to the Ontario – Quebec border. The Property consists of 585 cell claims in Steele, Case, Scapa, Pliny, Abbotsford and Challies townships, Larder Lake Mining Division. The Property is 10km by 9.5km in size with 14 granitic domes. The Case Lake pegmatite swarm consists of six spodumene dykes known as the North, Main, South, East and Northeast dykes on the Henry Dome, and the West Joe dyke on a new dome, collectively forming mineralization trend that extends for approximately 10km (Figure 5).

 

Power Metals have completed several exploration campaigns that have led to the discovery and expansion of new and historic spodumene bearing LCT pegmatites at Case Lake. The Company has drilled a total of 19,607 meters of core between 2017 and 2024 at the Property. The Case Lake Property is owned 100% by Power Metals Corp. A National Instrument 43-101 Technical Report has been prepared on Case Lake Property and filed on July 18, 2017.

 

Pelletier Property

 

The Pelletier Property is located 50km south of Hearst, northeastern Ontario close to a network of forestry roads. The Property consists of 337 mineral claims that account for a total of 7000 hectares in Franz, Roche, Scholfield, and Talbot townships in the Porcupine mining division. The Pelletier Project is characterized by LCT prospective S-type pegmatitic granites intruding into metasedimentary and amphibolite of the Quetico at or near Archean terrane boundary between the Quetico and Wawa sub-provinces (Figure 5).

 

Decelles Property

 

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 5).

 

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 5).

 

Pollucite and Cesium

 

Pollucite is a rare mineral that hosts high grade cesium and is associated with highly fractionated, compact, and 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.
