SW3

Regional exploration property forming part of NexGen's 100%-owned land package in the southwestern Athabasca Basin of Saskatchewan, alongside SW1 and SW2 (which hosts the Rook I Project and the Patterson Corridor East discovery). A high-resolution magnetic survey was carried out over SW3 in the fall of 2025 to advance interpretations and prioritize drill-ready targets, following earlier airborne and ground geophysical coverage of high-priority areas. Exploration strategy focuses on systematically investigating for additional uranium mineralization through drilling of advanced targets and geophysical surveys to create more drill-ready targets. No mineral resource estimate is disclosed for the property.
