NexGen Significantly Expands Strike Length of Higher Grade A2 Sub-Zone with AR-15-57c3 intersecting 5.0m at 49.60% U3O8 Within 31.5m at 10.03% U3O8

VANCOUVER, Nov. 30, 2015 /CNW/ - NexGen Energy Ltd. (TSX-V: NXE) ("NexGen" or the "Company") is pleased to report assay results from six angled directional holes from our highly successful summer 2015 drilling program on our 100% owned Rook I property, Athabasca Basin, Saskatchewan.

With hole AR-15-57c3, the higher grade A2 sub-zone (the "Sub-Zone", see Figure 2) strike length has now been expanded by approximately 25% from 162 m to 203 m.  This Sub-Zone is currently defined by holes AR-15-59c2 bordering the southwest of the zone and AR-14-30 to the northeast. Hole AR-15-57c3 has confirmed strong continuity of high-grade mineralization northeast of hole AR-15-49c2 and is now interpreted to continue to AR-14-30. Hole -57c3 was drilled 37 m up-dip and northeast of AR-15-49c2 (50.0m at 12.01% U₃O₈, see news release dated September 8, 2015). 

Additionally, assay results from two other strongly mineralized drill holes (AR-15-59c2 and -62) within the Sub-Zone remain pending.  Further testing for northeast and southwest extensions of the Sub-Zone will be a priority for the winter 2016 drill program.   

Furthermore, hole AR-15-57c3 continued with impressive assay results in the A3 shear by returning 50.5 m at 2.74% U₃O₈.  In addition, AR-15-57c2 intersected strong mineralization in the A3 shear returning 29.5m at 5.89% U₃O₈. A significant volume of mineralization in now quickly developing in the vicinity of these two drill holes within the A3 shear. Further drill testing of this new developing higher grade area is currently planned for the upcoming winter 2016 drill program.

Drill hole locations, and the A2 and A3 long sections are shown in Figures 1 to 4, angled drill hole results from the A2 sub-zone are in Table 1, and assay results are shown in Table 2.

Highlights:

A3 Shear

• AR-15-57c2 (96 m up-dip and to the northeast from AR-15-48c1) intersected 29.5 m at 5.89% U₃O₈ (580.5 to 610.0 m) including 15.5m @ 10.27% U₃O₈ in the A3 shear;
• AR-15-57c3 (49m up-dip and to the northeast from AR-15-48c1) intersected 50.5 m at 2.74% U₃O₈ (579.5 to 630.0 m) in the A3 shear;
• AR-15-54c2 intersected 14.5 m at 2.66% U₃O₈ (671 to 685.5 m) in the A3 shear.

Arrow, Activities & Financial

• The land-based and basement hosted Arrow zone currently covers an area of 645 m by 235 m with a vertical extent of mineralization commencing from 100 m to 920 m, and remains open in all directions and at depth.
• Preparations for a fully-funded 2016 are well advanced. A winter drilling program is scheduled to commence in early January 2016 along with environmental monitoring and baseline studies followed by a summer drilling program and engineering studies to provide a sound basis for the commencement of future feasibility studies.
• A maiden NI 43-101 resource estimate on the Arrow zone scheduled for the first half of 2016.
• 14 assays remain pending from the summer 2015 drill program.
• The Company has cash on hand of approximately $16.5M. Additionally, the Company announced a $20M bought deal financing on November 18, 2015 which is scheduled to close on or about December 9, 2015.

Garrett Ainsworth, NexGen's Vice-President, Exploration and Development, commented "Assay results from hole AR-15-57c3 in the A2 sub-zone have far surpassed our expectations.  We have now increased the strike length of the sub-zone by 41 m (162 to 203 m), which has an average true thickness of approximately 27.3 m calculated from seven drill holes (assays pending on two drill holes).  The significant expansion of the sub-zone during the summer drill program has been a huge accomplishment, which is marked by several angled drill intercepts that rank among the world's best in terms of continuous GT (grade x thickness) on public record.  In addition, wide intervals of high grade uranium mineralization continue to pile up in the A3 high grade core as described in this release with holes AR-15-57c2 and -57c3.  Preparations are well underway for an exciting winter 2016 drill program that will focus on continuing to develop Arrow and Bow, bold step-outs to the southwest and northeast of Arrow, testing for additional higher grade zones within the currently defined area of mineralization, and regional targets that share similar geophysical signatures to Arrow and Bow." 

Leigh Curyer, Chief Executive Officer commented, "The rapid emergence of the A2 sub-zone during summer 2015 has been a highlight amongst many at Arrow which had a 100% hit rate during the season intersecting uranium mineralization. To discover the sub-zone whilst systematically testing the A2 shear at approximately 50 m centers has elevated Arrow to another magnitude in a relatively short period of time. With a strong treasury balance, forecasted to be $31M to begin 2016, the Company is well positioned to execute on all drilling and engineering programs well into 2017 and advance Arrow at an optimal rate of progress."
