NexGen Energy Ltd. (TSX: NXE / OTCQX: NXGEF)("NexGen" or the "Company") is pleased to report assay results for 23 holes from our summer drilling program on our 100% owned, Rook I property, Athabasca Basin, Saskatchewan.
The following news release covers high grade assay results from the following:
- A2 High Grade Domain,
- Step-out holes northeast of AR-14-30,
- The "gap" area between the southwest boundary of Arrow and the 180m area,
- A1 and A3 expansion.
A2 High Grade Domain:
At Arrow, both step-out and infill holes show significant and widespread high-grade uranium mineralization. In the A2 High Grade Domain, scissor hole AR-16-111c1 returned 60.0 m at 4.70% U3O8 including 27.0 m at 10.27% U3O8. Additionally, scissor hole AR-16-106c1 which was drilled 55 m northeast and up-dip from AR-16-111c1 returned 40.5 m at 6.92% U3O8 including 27.0 m at 10.10% U3O8.
Step-out holes northeast of AR-14-30:
Assays from four step-out holes drilled northeast of the A2 High Grade Domain have confirmed the presence of strong uranium mineralization. Highlighting this is hole AR-16-108c2, which was drilled 30 m northeast of AR-14-30 (see News Release dated October 6, 2014) and outside of the A2 High Grade Domain returned 49.5 m at 3.07% U3O8 including 11.0 m at 10.23% U3O8.
The "gap" area between the southwest boundary of Arrow and the 180m area:
In the area between the Arrow Deposit grade shells and the mineralized area 180 m to the southwest, assays indicate that solid zones of uranium mineralization are present. In this area, hole AR-16-103 which was drilled 265 m down-dip and northeast from hole AR-16-90c3 (see News Release dated June 13, 2016), returned 17.5 m at 1.75% U3O8 including 8.0m at 3.63% 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.
A1 and A3 Expansion:
In the A3 shear, where the mineralized footprint has been materially expanded during 2016, assays from infill holes have confirmed the strong continuity of mineralization. Scissor hole AR-16-102c1 returned 15.0 m at 2.46% U3O8 including 3.0 m at 11.26% U3O8 located 88 m above the A3 inferred mineral resource domains. In addition, scissor hole AR-16-105c1 returned 23.5 m at 2.93% U3O8 and AR-16-105c2 returned 14.0 m at 1.17% U3O8.
In the A1 shear, step-out hole AR-16-108c4 returned 18.0 m at 2.36% U3O8 including 4.0 m at 8.94% U3O8 southwest of the A1 inferred mineral resource domains.

Arrow, Activities & Financial
- Preparations for a 35,000 m winter drill program to begin in late January 2017 are in process.
- An updated NI 43-101 resource estimate on the Arrow Deposit is scheduled for the first half of 2017.
- The Company has cash on hand of approximately $73 million.
- Assays from 32 holes remain pending; 10 from Arrow (including 2 A2 Sub-Zone holes), 20 from Harpoon and 2 regional exploration holes.
The A2, A3 and a schematic long section showing the 180 m southwest mineralized area as well as a plan map with hole locations are shown in Figures 1 to 4. Table 2 shows complete assay results from this release.
Garrett Ainsworth, Vice-President, Exploration and Development, commented: "Exceptional continuity in the A2 High Grade Domain is clearly evident from the results reported herein, where two scissor drill holes (AR-16-111c1 and -106c1) located 55 m apart have returned the same interval and grade (27.0 m at 10% U3O8). In addition, high grade assays returned in the A3 and A1 shears, which are located within and outside of their respective maiden resource grade shells demonstrate expansion of the A1 and A3 shears. Further, assays returned in the gap between the southwest extent of Arrow and the 180m area indicates solid continuity in the only 3 holes drilled in that area to date."
Leigh Curyer, Chief Executive Officer, commented: "Multiple high grade assay returns in all the key areas of focus at Arrow. We look forward to receiving the pending 10 assay results from Arrow due shortly, then initiating the engagement for an updated resource estimate to be released in the first half of 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 intervals are core lengths; true thicknesses are yet to be determined. Resource modelling in conjunction with an updated mineral resource estimate is required before true thicknesses can be estimate.
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. Please see the Rook I Technical Report (as defined below) for detail of our QA/QC protocols.
