Power Metals completes final cesium tests at Case Lake

Executive Summary

• Power Metals Corp. successfully produced technical‑grade cesium formate (99.8 % purity, 2.23 g/mL density) and cesium chloride (99.6 % purity) from Case Lake pollucite concentrate, confirming a 97 % cesium extraction efficiency.
• The results de‑risk the West Joe pegmatite zone and demonstrate near‑term feasibility for commercial-scale production of high‑purity cesium chemicals, lithium, and tantalum concentrates.
• CEO Haydn Daxter and Chairman Johnathan More highlighted the milestone as proof that Case Lake can become a low‑impurity, cost‑effective North American source of critical minerals for multiple end‑markets (oil & gas, solar/battery, military, medical).

Key Details

• Extraction Efficiency: 97 % cesium extraction from pollucite concentrate (average feed grade 19.5 % Cs₂O).
• Cesium Formate: Technical grade, 99.8 % purity, density 2.23 g/mL (industry range 2.2–2.4 g/mL).
• Cesium Chloride: Technical grade, 99.6 % purity with very low impurities.
• Crystallization Process: Two‑stage crystallization at 50 °C and 20 °C achieved overall crystal recovery efficiencies of 95–98 %; recrystallization yielded final efficiencies up to 98 %.
• Sample Origin: Blended concentrate from Phase I ore‑sorting (samples 24‑036‑01P & 24‑036‑03P), crushed to 100 % passing 106 µm.
• Test Facility: SGS Canada, Lakefield, Ontario – independent qualified person verification.
• Additional Milestones: Confirms ability to produce technical‑grade cesium chemicals, lithium concentrate (Li₂O) and tantalum concentrate (Ta) from the same ore stream; supports de‑risking of Phase I & II XRT ore‑sorting, bulk sample production, and future commercial operations.
• Project Context: Case Lake remains the only global project with near‑term cesium production capacity; over 7,000 m of drilling completed to date.
• Quotes:
• Haydn Daxter (CEO): “The completion of our metallurgical testwork… confirms Case Lake as a near‑term cesium operation with low impurity and cost‑effective processing for the North American market.”
• Johnathan More (Chairman): “This final round of metallurgical testwork… demonstrates strong confidence to shareholders as we continue to de‑risk the project in preparation for production.”
