Potential • The Horizon property covers a 25 kilometre strike extension of the magnetic low trend which hosts the Moonlight Uranium Zone, Osprey Zone, and other significant occurrences • No drill holes have tested this fertile trend within the Horizon Project • Minimal modern exploration has been applied on the property Next Steps

• Airborne VTEM survey to outline map graphitic conductors and enhance magnetic data resolution • Radiometric survey to identify mineralized outcrops and boulders • Drill test areas of structural complexity
