Hole AR-16-78c4 Assay Returns 37.5 m at 17.60% U3O8 including 5.5 m at 60.14% U3O8
Vancouver, BC, June 21, 2016 - NexGen Energy Ltd. ("NexGen" or the "Company") (TSXV:NXE, OTCQX:NXGEF) is pleased to report assay results for eight angled holes from our highly successful winter 2016 drilling program on our 100% owned, Rook I property, Athabasca Basin, Saskatchewan.
Assay results from the higher grade A2 Sub-Zone ("Sub-Zone") have yet again confirmed strong uranium grades over significant intervals at the Arrow Deposit. Hole AR-16-78c4 which was drilled 59 m up-dip and northeast of hole AR-15-44b has returned 37.5 m at 17.60% U3O8 including 5.5 m at 60.14% U3O8 and 1.5 m at 71.93% U3O8. This intersection represents a continuous grade x thickness ("GT") of 660, the fourth highest at Arrow. Within the A2 shear drill hole AR-16-78c4 returned a total composite GT of 834.
Additionally, drill hole AR-16-76c4 returned 68.0 m at 2.09% U3O8 including 14.5 m at 5.08% U3O8 and an additional section of 32.0 m at 1.97% U3O8 including 10.0 m at 5.15% U3O8. Of key importance, high grade mineralization encountered in both holes was largely intersected outside the current limits of the A2 High Grade Domain (see Figure 1). Assay results for 23 holes at Arrow remain pending.

Highlights: A2 Sub-Zone
-
AR-16-78c4 (59 m up-dip and northeast from AR-15-44b) intersected 37.5 m at 17.60% U3O8 (480.5 to 518.0 m) including 15.0 m at 29.92% U3O8 (490.0 to 505.0 m) and 1.5 m at 71.93% U3O8 (493.5 to
495.0 m) in the Sub-Zone.
-
AR-16-76c4 (81 m down-dip and southwest of AR-15-44b) intersected 68.0 m at 2.09% U3O8 (576.5 to
644.5 m) including 14.5 m at 5.08% U3O8 (629.0 to 643.5 m) and an additional 32.0 m at 1.97% U3O8
(537.5 to 569.5 m) including 10.0 m at 5.15% U3O8 (556.5 to 566.5 m) in the Sub-Zone.
Arrow, Activities & Financial
-
The land-based and basement hosted Arrow zone currently covers an area of 870 m by 280 m with a vertical extent of mineralization commencing from 100 m to 920 m, and remains open in most directions and at depth.
-
The spring 2016 program comprising 7,500 m of drilling will be transitioning to the summer 2016 program in late-June.
-
The Company has approximately cash on hand of $100 million.
A three-dimensional view of the A2 Sub-Zone, drill hole locations and a close-up of the A2 long section are shown in Figures 1 to 3. Assay results are presented in Table 2.
Garrett Ainsworth, Vice-President, Exploration and Development, commented "Drill holes -78c4 and -76c4 highlight the strong continuity of grade and thicknesses across the A2 sub-zone from northeast to southwest. As shown in Figure 1, large sections of these assayed holes are outside the A2 high grade domain shell upon which Arrow's Maiden Resource was estimated. Infill drilling is delivering strong continuity of mineralization and will expand the volume of the A2 high grade domain shell."
Leigh Curyer, Chief Executive Officer, commented: "The assay results continue to exceed our objectives of infill drilling by delivering broader and higher grade intervals. Preparations for the summer drill season are in their
final stages which will continue to focus on the known area of mineralization, the new area 180 m southwest of Arrow, and along trend to the northeast and southwest along the Patterson Corridor."
