NexGen Makes New Discovery 400 m South of Arrow

NexGen Energy (“NexGen” or the “Company”) (TSX:NXE, NYSE:NXE) is pleased to report a new uranium discovery during our on-going summer drilling program on our 100% owned, Rook I property, Athabasca Basin, Saskatchewan.
The first two exploration holes of the summer drill program have resulted in the discovery of a new zone of off-scale radioactivity approximately 400 m south of the Arrow Deposit. This new area of mineralization has been named the South Arrow Discovery and is located on an Arrow-parallel structure that remains almost completely undrilled.
Arrow South Discovery Characteristics:

• Highly Radioactive – Mineralization is locally very strong observed as dense massive pitchblende veins. Intermittent anomalous uranium-sourced radioactivity occurs over core lengths of up to 400 m, which supports that a large and robust uraniferous alteration system is present at South Arrow.
• Multiple lenses – Preliminary interpretations at South Arrow suggest that steeply southeast dipping mineralization occurs within at least three stacked high strain or sheared intervals, which is a common characteristic of the Arrow Deposit.
• Extensive Alteration – Similarly to Arrow, the hydrothermal alteration is widespread, which suggests a strong mineralizing event has occurred. Dravite and illite breccias are observed at the Arrow Deposit and the South Arrow zone.
