NexGen Energy (NXE-T) July 27, '16 is pleased to report assay results for one hole from our recently completed winter 2016 drilling program on our 100% owned, Rook I property, Athabasca Basin, Saskatchewan.
Assay results have established that hole AR-16-81c2 has discovered a new zone of high-grade uranium mineralization in what has been named the A5 shear. The A5 shear is located adjacent southeast of the A4 shear as shown in Figures 1 and 2.
Highlights:
New A5 Shear Discovery
AR-16-81c2 (discovery hole) intersected 9.5 m at 2.08% U3O8 and 4.0 m at 5.18 % U3O8 and 6.5 m at 2.55% U3O8.
Additionally, when not considering internal dilution, AR-16-81c2 intersected 58.5 m at 1.26% U3O8 (848.5 to 907.0 m) in the A5 shear.
The Arrow Deposit is now comprised of five high-grade shear zones; A1, A2, A3, A4 and A5 that are sub-parallel to each other and have a combined thickness of 280 m. The A5 shear is completely untested between hole -81c2 and the unconformity which is approximately 105 m below surface or 685 m above the hole. The mineralized zone intersected in AR-16-81c2 is open in all directions.

Arrow, Activities & Financial
The land-based and basement hosted Arrow Deposit 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 summer 2016 program comprising 35,000 m of drilling is underway with seven drill rigs active.
The Company has cash on hand of approximately $100 million.
A plan map and 3-D view of the location of the A5 shear are shown in Figures 1 and 2. Table 2 shows complete assay results.
Garrett Ainsworth, Vice-President, Exploration and Development, commented "The discovery of high grade mineralization in the new A5 shear has now been established with drill hole AR-16-81c2 returning an impressive total composite GT of 74. The mineralization is open in all directions with a completely untested 685m vertical extent from hole -81c2 up to the unconformity."
Leigh Curyer, Chief Executive Officer commented: "The discovery of the A5 shear with strong grade is very exciting for the Arrow Project and NexGen. It presents another objective for this summer's drilling season in testing the A5 shear and for additional parallel shears at Arrow. Figures 1 and 2 highlight the extent of the area that remains untested."

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.
