VANCOUVER, Oct. 3, 2016 /CNW/ - NexGen Energy Ltd. ("NexGen" or the "Company") (TSX:NXE, OTCQX:NXGEF) is pleased to report assay results for six holes from our summer drilling program on our 100% owned, Rook I property, Athabasca Basin, Saskatchewan.

At Arrow, holes drilled from both northwest to southeast (original) and southeast to northwest (scissor) directions have encountered significant high grade uranium mineralization within and outside the A2 High Grade Domain.

Highlighting this batch of results, hole AR-16-92c3 intersected two continuous intervals with grade x thicknesses ("GT" as %U3O8 x meters) of 144 and 115 that pierced 30 m below the A2 High Grade Domain. These two intervals were separated by 4 meters of core length in the hole. In addition, scissor holes AR-16-93c2 intersected a continuous GT of 279 in the Sub-Zone near the top of the A2 High Grade Domain, AR-16-91c4 returned a continuous GT of 215, and AR-16-93c1 returned a continuous GT of 163.

In the new A1 discovery area, scissor holes AR-16-91c4 and -93c2 both intersected significant intervals of uranium mineralization.

Highlights:

A2 High Grade Domain

• Scissor hole AR-16-93c2 (109 m up-dip and northeast from AR-15-44b) intersected 53.0 m at 5.27% U3O8 (452.5 to 505.5 m) including 12.0 m at 20.21% U3O8 (480.5 to 492.5 m) and 2.0 m at 68.00% U3O8 (485.5 to 487.5 m).
• Hole AR-16-92c3 (91 m down-dip and southwest from AR-15-44b) intersected 14.0 m at 8.21% U3O8 (611.0 to 625.0 m) including 5.0 m at 18.75% U3O8 (620.0 to 625.0 m) and an additional interval of 12.0 m at 12.02% U3O8 (629.0 to 641.0 m) including 7.0 m at 20.44% U3O8 (629.0 to 636.0 m).
• Scissor hole AR-16-91c4 (70 m up-dip and northeast from AR-15-44b) intersected 43.5 m at 4.95% U3O8 (497.5 to 541.0 m) including 12.0 m at 16.70% U3O8 (527.0 to 539.0 m).
• Scissor hole AR-16-93c1 (13 m up-dip and northeast from AR-15-44b) intersected 54.0 m at 3.02% U3O8 (447.0 to 501.0 m) including 5.0 m at 26.22% U3O8 (472.5 to 477.5 m).

A1 Shear New Discovery Area

• Scissor hole AR-16-91c4 (25 m down-dip and northeast from AR-16-84c1) intersected 32.0 m at 1.19% U3O8 (695.5 to 727.5 m) and an additional 48.0 m at 0.30% U3O8 (630.5 to 678.5 m).
• Scissor hole AR-16-93c2 (34 m up-dip and northeast from AR-16-84c1) intersected 24.0 m at 1.31% U3O8 (697.5 to 721.5 m).

Activities & Financial

• The summer 2016 program of seven drill rigs has been extended and will conclude late October 2016.
• The Company has cash on hand of approximately $85 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 high grade assay intervals returned from each drill hole reported herein exhibit the robust nature of the Arrow Deposit.  The A2 High Grade Domain continues to expand, while the new high grade zone within the A1 Shear has returned superb results which requires substantial drilling to properly assess the large untested surrounding areas."     

Leigh Curyer, Chief Executive Officer commented: "These assay results are meeting the summer program objectives of Arrow infill and expansion drilling in demonstrating strong continuity of the A2 High Grade Domain and increasing the area of defined mineralization in the A1 shear. Summer drilling has been extended to the end of October 2016 with the Company targeting an updated Arrow resource for 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 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.
