Power Metals Intersects World Class High-Grade Cesium up to 24.07% at Case Lake, Rarely Seen in Canada

VANCOUVER, BC, Oct. 13, 2022 /CNW/ - Power Metals Corp. ("Power Metals" or the "Company") (TSXV: PWM) (FRANKFURT: OAA1) (OTCQB: PWRMF) is pleased to announce ongoing drill results from the West Joe Dyke at its 100% owned Case Lake Property in Cochrane, Ontario.

Highlights Include (Table 1):

• 24.07 % Cs₂O, 0.63 % Li₂O, 34.2 ppm Ta over 1.0 m, 15.0 to 16.0 m, PWM-22-143
• 20.36 % Cs₂O, 2.28 % Li₂O, 15.7 ppm Ta over 1.0 m, 14.0 to 15.0 m, PWM-22-143
• 22.22 % Cs₂O, 1.46 % Li₂O, 25.1 ppm Ta over 2.00 m, 14.0 to 16.0 m, PWM-22-143
• 7.65 % Cs₂O, 1.45 % Li₂O, 247.1 ppm Ta over 7.09 m, 11.96 to 19.05 m, PWM-22-143 (Figure 1).
• 1.94 % Cs₂O, 2.20 % Li₂O, 466.0 ppm Ta over 8.98 m, 20.97 to 29.95 m, PWM-22-144
• 2.71 % Cs₂O, 4.75 % Li₂O, 396.0 ppm Ta over 2.00 m, 24.00 to 26.00 m, PWM-22-144
• 3.66 % Cs₂O, 1.05 % Li₂O, 1440.0 ppm Ta over 1.00 m, 48.00 to 49.00 m, PWM-22-147

Drilling on the West Joe Dyke has intersected multiple pollucite intervals with up to 24.07 % Cs₂O at a shallow depth of 15.00 m in drill hole PWM-22-143. Pollucite is the only ore mineral of Cs. The West Joe pollucite zone is characterized by secondary lepidolite (Li) and muscovite along fractures in massive white pollucite. The pollucite zone is enclosed within the inner intermediate zone consisting of coarse-grained pale green spodumene (Li), coarse-grained white K-feldspar enriched in Rubidium (Rb), and Ta-oxide minerals.

SGS Burnaby, British Columbia analytical lab was so surprised by the exceptionally high cesium assays that they assayed the samples multiple times and further sent the samples to SGS Lakefield, Ontario which confirmed the numbers and signed off on the assay certificate. Dr. Julie Selway, VP of Exploration, reassured SGS that the cesium results were to be expected because pollucite was visible in the drill core.

Dr. Selway states, "The drill core with 24.07 % Cs₂O over 1.0 m is the highest and most impressive cesium assay in properties that I have worked on in my career. One of Power Metals' goals for the summer 2022 drill program was to follow up on the 14.70 % Cs₂O over 1.0 m in drill hole PWM-18-126 from 2018. The 2022 drilling cesium results have surpassed the 2018 results and has further confirmed the economic value of the West Joe Dyke."

Chairman & CEO, Johnathan More, stated "These cesium high-grade zones have far exceeded our expectations this early in the game. World leader, Sinomine Resource Group, invested in Power Metals earlier this year and both parties are excited with these results. Cesium is extremely rare to find and is currently not being mined anywhere in the world. Historically, it is found in small quantities and the current mineralization seen at Case Lake is being found near surface. These results along with reported and ongoing lithium mineralization is creating massive value for this property."

The West Joe pollucite zone has Cs grades similar to that of Sinclair cesium mine, Australia held by Essential Metals Limited (ASX: ESS). Pollucite was mined by open pit from the Sinclair mine in 2018 (Pioneer Resources Limited, press release dated Dec. 12, 2018). There are only two other commercial cesium mines globally: Tanco mine, Manitoba and Bikita mine, Zimbabwe. In addition to the Cs grade, West Joe has the advantages that the pollucite has shallow depths of less than 50 m below surface and road access to make it easy for future extraction. Another advantage of West Joe is that it has three economic commodities in the same zone: lithium, cesium and tantalum. Canadian, Ontario and United States governments have labelled all three commodities as critical metals.

Drill holes are oriented perpendicular to the strike length of the pegmatite, so mineralization is close to true width.

The pollucite zone at West Joe differs from the other three global cesium mines in that at West Joe spodumene is the dominant lithium mineral whereas at the other cesium mines petalite and lepidolite are the dominant lithium minerals.

The primary use of the cesium mined at Tanco, Manitoba is for cesium formate brines used for high pressure, high temperature well drilling for oil and gas. Cesium bromide is used in infrared detectors, optics, photoelectric cells, scintillation counters and spectrometers (USGS Mineral Commodity Summaries 2022). Cesium isotopes are used in atomic resonance frequency in standard atomic clocks which play a vital role in aircraft guidance systems, global positioning satellites and internet and cellular telephone transmissions (USGS Mineral Commodity Summaries 2022).

West Joe Dyke was discovered for its spodumene (Li) mineralization in August 2018. Drilling on the Dyke lead to the discovery of cesium mineralization in the fall of 2018 with six drill holes intersecting pollucite in drill core (i.e., PWM-18-111, 112, 116, 123, 124 and 126). The best assay was 6.74 % Cs₂O over 5.00 m, 11.00 to 16.00 m interval including 14.70 % Cs₂O over 1.00 m, 13.00 to 14.00 m interval from drill hole PWM-18-126 (PWM press release dated Nov. 13, 2018).  Summer 2022 drilling has intersected pollucite in five drill holes (i.e., PWM-22-128, 143, 144, 145 and 147). Cesium assays of 6.53 % Cs₂O, 1.28 % Li₂O and 324.0 ppm Ta over 1.0 m were previously disclosed in a press release dated Aug. 19, 2022.

Power Metals 2022 summer drill program is for 5000 m and over 2700 m has been completed to date. This press release reports assays received to date from drill holes PWM-22-141 to 147 on the West Joe Dyke. The purpose of each drill hole was to infill on known mineralization to aid in a future resource estimate.

The drill core was sampled so that 1 m of the Case Batholith tonalite host rock was sampled followed by 1 m long samples of the pegmatite dyke and 1 m of the Case Batholith. The sampling followed lithology boundaries so that only one lithology unit is within a sample, except for the < 20 cm pegmatite veins in tonalite which were merged into one sample. The drill core samples were delivered to SGS preparation lab in Cochrane by Power Metals' geologists. The core was prepared at SGS Garson and analyzed at SGS Burnaby, British Columbia which has ISO 17025 certification. Every 20 samples included one external quartz blank, one external lithium standard and one core duplicate. The ore grade Li₂O% was prepared by sodium peroxide fusion with analysis by ICP-OES with a detection limit of 0.002 % Li₂O. A Quality Control review of the standards, blanks and core duplicates indicated that they all passed. The ore grade Cs₂O% for > 10000 ppm Cs was prepared by alkaline metal digestion with analysis by FAAS with a detection limit of 0.002 % Cs. Ore grade cesium was analyzed by SGS Lakefield, Ontario which also has ISO 17025 certification.
