NexGen Energy (NXE-T) Aug 8, '16 is pleased to report assay results for seven holes from our recently completed winter 2016 drilling program on our 100% owned, Rook I property, Athabasca Basin, Saskatchewan.
Highlights:
A2 Sub-Zone
Scissor drilling collared from the southeast to the northwest at the Arrow Deposit has returned extensive high grade uranium mineralization in the higher grade A2 sub-zone (the "Sub-Zone").
Scissor hole AR-16-91c2 (38 m up-dip and northeast from AR-15-44b) intersected 40.5 m at 12.69% U3O8 (522.0 to 562.5 m) including 25.0 m at 19.97% U3O8 (526.0 to 551.0 m) and 1.5 m at 63.93% U3O8 (541.0 to 542.5 m).
Hole AR-16-91c2 has confirmed and increased the known width of the Sub-Zone and returned a continuous grade x thickness ("GT") of 514. The Sub-Zone is now outlined by 23 holes, all of which intersected dense accumulations of massive-to-semi-massive pitchblende, sixteen of which were drilled after the release of the Company's maiden NI 43-101 compliant Inferred Mineral Resource for the Rook I project on March 3, 2016.
A2 Shear High-Grade Domain
Infill drilling continues to verify that mineralization in the A2 shear is both extensive and continuous. These include 3 scissor holes drilled outside of the Sub-Zone but inside the A2 High-Grade Domain; highlights include:
Scissor hole AR-16-84c4 (30 m down-dip and northeast from AR-15-44b) intersected 38.0 m at 1.92% U3O8 (566.0 to 604.0 m) including 11.0 m at 6.15% U3O8 (573.5 to 584.5 m).
Scissor hole AR-16-91c3 (96 m up-dip and northeast from AR-15-44b) intersected 18.5 m at 3.26% U3O8 (485.0 to 503.5 m) including 7.5 m at 7.40% U3O8 (490.5 to 498.0 m).
A1 Shear
Significant expansion of the newly discovered mineralized zone in the A1 shear has been confirmed. The A1 shear remains primarily untested, and is already host to mineralization over a strike length of 360 m.
AR-16-91c3 (30 m up-dip and northeast from AR-16-84c1) intersected 19.0 m at 0.82% U3O8 (628.0 to 647.0 m) including 3.5 m at 3.05% U3O8 (639.5 to 643.0 m), and 6.0 m at 1.02% U3O8 (657.0 to 663.0 m).

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 $91 million.
A three-dimensional view of the A2 High Grade Domain, long sections of the A1 and A2 shears, and a plan map are shown in Figures 1 to 4. Table 2 shows complete assay results.
Garrett Ainsworth, Vice-President, Exploration and Development, commented: "The robust nature of the higher grade A2 sub-zone is clearly evident with scissor hole AR-16-91c2 returning a continuous GT of 514. The drill results continue to be outstanding whether the sub-vertically dipping mineralization is drilled from the northwest to the southeast or vice versa. Additionally, the mineralized zone in the A1 shear is expanding rapidly since discovery hole AR-16-84c1."
Leigh Curyer, Chief Executive Officer commented: "These batch of results deliver two important objectives of the summer drilling program. Firstly, the scissor holes confirming the robust nature of the higher grade A2 sub-zone and secondly, expanding the area of mineralization within the A1 shear. The combination of infill drilling, expansion testing and regional exploration is meeting all the objectives of the summer program."

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.
