Power Metals Intersects High-Grade Lithium, Cesium and Tantalum Mineralization at West Joe and Main Dykes, Case Lake

 

 

 

 

 

Power Metals Corp.  (TSX-V: PWM) (FRANKFURT: OAA1) (OTCQB: PWRMF) is pleased to announce that drill holes have intersected high-grade Li, Cs and Ta (Lithium, Cesium and Tantalum) mineralization on the West Joe Dyke and Li and Ta mineralization on the Main Dyke, Case Lake property, Cochrane, Ontario.

 

Johnathan More, Chairman & CEO of Power Metals, commented “These fantastic drill results continue to impress our strong geological team. Drilling is ongoing and we are extremely excited for the next round of assays to be received from the lab.”

 

The lithium mineralization is mainly spodumene, but also lepidolite at West Joe and is spodumene on the Main Dyke. Cesium mineralization is pollucite at West Joe and Ta mineralization is Ta-oxides at West Joe and Main Dykes.

 

Assay highlights on West Joe Dyke include (Table 1):

  • 1.11 % Li2O (lithium), 2.15 % Cs2O (cesium) and 365.46 ppm Ta (tantalum) over 6.84 m, PWM-22-128 (Figure 1)
  • 1.28 % Li2O, 6.53 % Cs2O and 324.0 ppm Ta over 1.0 m, PWM-22-128
  • 1.75 % Li2O, 0.06 % Cs2O and 221.0 ppm Ta over 1.0 m, PWM-22-129
  • 1.74 % Li2O, 0.01 % Cs2O, 197.0 ppm Ta over 0.79 m, PWM-22-130.

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

 

Drill hole PWM-22-131 intersected biotite-rich metasedimentary host rock with elevated Li, Rb and Cs contents from 45.89-47.30 m, 1.41m interval with 0.49 % Li2O, 3094 ppm Rb and 0.47 % Cs2O. This metasomatized host rock can be used as a pathfinder to locate blind pegmatites on the property.

 

Assay highlights on Main Dyke include (Table 2):

  • 1.71 % Li2O and 240.77 ppm Ta over 12.0 m, PWM-22-132 (Figure 2)
  • 1.20 % Li2O and 218.68 ppm Ta over 19.0 m, PWM-22-133.

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

 

Power Metals’ 2022 summer drill program is for 5,000 m and over 2,000 m has been completed to date. This press release reports assays received to date from drill hole PWM-22-128 to 131 on the West Joe Dyke and drill holes PWM-22-132 and 133 on the Main Dyke. The purpose of each drill hole was to infill on known mineralization to aid in a future resource estimate.

Quality Control

 

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. The ore grade Cs2O% was prepared by acid digestion with analysis by AAS with a detection limit of 0.01 % Cs. A QA/QC review of the standards and blanks for this drill program indicate that they passed and the drill core assays are accurate and not contaminated.
