NexGen Energy (“NexGen” or the “Company”) (TSX:NXE,NYSEMKT:NXE) is pleased to report final assay results for  the winter 2017 drilling program at our 100% owned, Rook I property, Athabasca Basin, Saskatchewan.
A3 Shear Expansion Drilling
Step-out hole AR-17-136c2 which intersected a new area of semi-massive to massive pitchblendemineralization in the A3 shear has returned high grade assays.   This high grade uranium mineralization was intersected 40 m outside the current resource, and 70 m outside the current A3 High Grade Domain.

• Step-out hole AR-17-136c2 (170 m northeast and up-dip from AR-15-57c2) intersected 13.5 m at 9.58% U3O8 (446.5 to 460.0 m) including 5.0 m at 23.49% U3O8 (451.0 to 456.0 m).
