<div id="readability-page-1"><div>(TheNewswire)Vancouver, British Columbia –December 9, 2025 – TheNewswire - Canadian Uranium Corp.(CSE: CANU) (formerly, Free Battery Metal Limited) (“CANU” or the“Company”), an exploration-focused company targeting high-potentialuranium projects in the Athabasca Basin of Northern Saskatchewan, ispleased to provide shareholders with an update on the next steps forits recently acquired 80% earn-in interest in the Castle South UraniumProject (formerly known as the Cable Lake Property) CANU is currently defining exploration targets andpreparing permit applications as it embarks on its initialinvestigation of the Castle South Uranium Project. The property issituated along the southern lip of the Athabasca Basin, where numerousinterpreted faults and structural features offer strong potential formineralization. The Company intends to explore these structures usingmodels similar to those that contributed to discoveries at PattersonLake South and the Arrow deposit.Three-Phase Exploration Program Beginning Q1 2026 Phase 1 – MT Survey &amp; Data Compilation The Company will commence a Magnetotelluric (MT) survey, a passive geophysical method that measures natural variations in Earth’s magnetic and electric fields—originating from lightning, solar winds, and other natural sources—to map subsurface electrical resistivity. This survey will help define the geology and identify geophysical anomalies across the claim group. The exploration target model is a classic unconformity-style uranium system, focusing on graphitic conductors within magnetic lows that may indicate a hydrothermal depositional environment. With an investigative depth of over 1 km, the MT survey will also help identify anomalies within magnetic breaks at depths consistent with the discoveries at PLS and Arrow. Phase 1 will also include a comprehensive data compilation program, integrating historical datasets with the new MT survey as the framework. Phase 2 – Field Prospecting &amp; Ground Geophysics Scheduled for spring and summer 2026, this phase includes radiometric surveys, ground magnetic (Mag) and induced polarization (IP) geophysics, and Man-portable Shaw drilling to test surface expressions. These activities are designed to correlate surface results with the subsurface anomalies identified in Phase 1, with the goal of defining high-priority diamond drilling targets. Phase 3 – Diamond Drilling Program Based on results from the first two phases, CANU anticipates a large-scale diamond drilling program totaling approximately 10,000 metres of NQ2 drilling. Historical data suggests that drill targets may exist between 100–550 metres depth. Drilling is expected to begin in September 2026. “Preparing our exploration strategy and exploration permit applications for the Castle South Uranium Project, marks an exciting step forward as we advance one of the more highly anticipated uranium targets in the basin. This milestone reflects our commitment to disciplined exploration and our confidence in the project’s potential to deliver meaningful discovery.” remarked Geoff Balderson, CFO About the Castle South Uranium Project Formerly known as the Cable Lake Property, the Project Castle South Uranium Project covers 20,600 hectares along the southern margin of the Athabasca Basin, a setting that provides distinctive geological characteristics and strong potential for uranium mineralization. The property hosts at least five high-priority target areas, including magnetic highs associated with listric and dyke structures, high-conductive anomalies, and approximately 52 km of electromagnetic conductors. These targets were originally identified in a 2007 airborne geophysical survey. About Canadian Uranium Corp. Canadian Uranium Corp. (CSE: CANU) is an emerging uranium exploration and development company focused on the prolific Athabasca Basin—the world’s premier district for high-grade uranium deposits.
