Nov. 8, 2016 - NexGen Energy Ltd. ("NexGen" or the "Company") (TSX:NXE, OTCQX:NXGEF) is pleased to report assay results for 14 holes from our highly successful summer drilling program on our 100% owned, Rook I property, Athabasca Basin, Saskatchewan.
Assays continue to confirm that holes drilled at the Arrow Deposit are strongly mineralized both inside and outside the A2 High Grade Domain as well as in other shears at Arrow including the A1 (see Figure 1). Of key importance, scissor hole AR-16-98c2 returned 73.5 m at 7.59% U3O8 including 26.5 m at 20.27% U3O8 and 10.0 m at 51.40% U3O8 both inside and outside the A2 High Grade Domain. This represents a continuous grade x thickness ("GT" in U3O8 x meters) of 558 which is the best interval drilled in any scissor hole (azimuth from southeast to northwest) at Arrow to date. Additionally, hole AR-16-96c2 returned 57.5 m at 4.17% U3O8 including 10.0 m at 15.73% U3O8 which was also intersected inside and outside of the A2 High Grade Domain.
In the A1 shear, hole AR-16-98c1 returned 21.0 m at 4.17% U3O8 including 5.0 m at 10.97% U3O8. The mineralized domains in the A1 shear remain largely undrilled over a strike length of at least 360 m. This represents a priority area for potential future resource growth.
In addition, the first assay results from the area between the Arrow Deposit grade shells, and the mineralized area 180 m to the southwest, have shown that strong, broad uranium concentrations are present. In this area, hole AR-16-97 returned 18.0 m at 2.64% U3O8 including 6.0 m at 5.89% U3O8. Mineralization extends from the Arrow Deposit 43-101 Inferred Mineral Resource to the southwest for at least 240 m where it remains open in all directions.
Highlights:
A2 Sub-Zone

Arrow, Activities & Financial
- The summer 2016 drilling program is nearing completion and the winter program will commence early 2017.
- The Company has cash on hand of approximately $75 million.
A three-dimensional view of the A2 High Grade Domain, long sections of the A1 and A2 shears, a schematic long section of the Arrow gap, and a plan map are shown in Figures 1 to 5. Table 2 shows complete assay results.
Garrett Ainsworth, Vice-President, Exploration and Development, commented: "These latest drill assay results confirm and surpass expectations from previously released radioactivity results, and show significant high grade uranium intervals inside and outside of the maiden inferred resource modelled grade shell domains. Drill hole AR-16-98c2 has returned the highest GT to date for a scissor hole, and has contributed to increased confidence of the A2 High Grade Domain contacts, while also demonstrating the sub-vertical nature of mineralization at Arrow.
Leigh Curyer, Chief Executive Officer, commented: "These multiple strong assays from the A2 High Grade Domain, the A1 shear, as well as the extension area southwest of Arrow to the 180 m Area, highlights significant drilling is required at Arrow before the true extent of mineralization can be determined. Planning for winter 2017 is already well underway and will commence prior to the release of an updated resource estimate in H1 2017."

Composite parameters:
- Minimum thickness 0.5 m downhole
- Cutoff grade 0.01% U3O8
- Maximum internal dilution 2.00 m downhole
- U3O8 analyzed by ICP-OES at SRC Laboratories, Saskatoon, Saskatchewan
- All depths and intervals are meters downhole, true thicknesses are yet to be determined
Split core samples were taken systematically, and intervals were submitted to SRC Geoanalytical Laboratories (an SCC ISO/IEC 17025: 2005 Accredited Facility) of Saskatoon for analysis. All samples were analyzed using ICP-MS for trace elements on partial and total digestions, ICP-OES for major and minor elements on a total digestion, and fusion solution of boron by ICP-OES. Mineralized samples were analyzed for U3O8 by ICP-OES and selected samples for gold by fire assay.
All assay batches reported herein are subjected to and have passed rigorous internal QA/QC protocols that include, but are not limited to, the blind insertion of standard reference materials, blank materials and field duplicates into the sample stream at both random and systematic intervals.
