SW1

Regional exploration property forming part of NexGen's 100%-owned land package in the southwestern Athabasca Basin of Saskatchewan, alongside SW2 (which hosts the Rook I Project) and SW3. SW1 has been the subject of regional exploration drilling programs (including the 2023 program that completed 22,114.4 m across SW1 and SW2 targets) and extensive geophysical programs over high-priority areas for drill target generation, testing prospective targets for uranium mineralization. Exploration strategy focuses first on areas near possible future Rook I infrastructure to maximize the economic viability of newly identified resources, before shifting to geologically high-priority targets across all land packages. No mineral resource estimate is disclosed for the property.
