NexGen Energy (NXE-V) Sept 8, '15 is pleased to report assay results for six angled holes from the recently expanded summer 2015 drilling program on our 100% owned Rook I property, Athabasca Basin, Saskatchewan.
Hole AR-15-49c2 has delivered substantial continuous high-grade uranium mineralization in the A2 shear similar to that encountered in hole AR-15-44b (see News Release dated June 15, 2015) and at shallower depth. Both holes are amongst the best uranium intersections drilled in the Athabasca Basin. In addition, hole AR-15-48c1 has returned broad and extensive uranium mineralization in both the A2 and A3 shears.
Highlights:
AR-15-49c2
AR-15-49c2 returns 50.0 m at 12.01% U3O8 (435.5 to 485.5 m) including 18.0 m at 20.55% U3O8 (456.0 to 474.0 m) and 4.5 m at 40.64% U3O8 (465 to 469.5 m) in the A2 shear;
Assay results continue to show that Arrow is a world-class discovery by returning a continuous composite grade thickness ("GT") of 605 (this is the second hole at Arrow with a continuous GT over 600);
Returned the highest grade assay result from the Arrow zone to date at 76.0% U3O8 over 0.50 m (466.5 to 467.0 m);
Located 41 m up-plunge to the northeast in the A2 shear from AR-15-44b (56.5 m at 11.55% U3O8).
AR-15-48c1
AR-15-48c1 returns 60.0 m at 0.91% U3O8 (409.5 to 469.5 m) including 12.5 m at 3.09% U3O8 (428.5 to 441.0 m) in the A2 shear and, 24.0 m at 5.43% U3O8 (595.5 to 619.5 m) including 10.5 m at 10.12% U3O8 (597.5 to 608 m) in the A3 shear;
Located 81 m up-dip and to the southwest in the A2 shear from AR-15-44b.
The Arrow zone which is entirely basement hosted currently covers an area of 645 m by 215 m with a vertical extent of mineralization commencing from 100 to 920 m, and remains open in all directions and at depth. Geochemical results continue to show highly anomalous gold values and very low deleterious metals content throughout the Arrow zone;
Five rigs continue to turn on the Arrow Zone as part of the 2015 summer drill program recently expanded to 30,000 m;
The Company has cash on hand of approximately $23M.
Garrett Ainsworth, NexGen's Vice-President, Exploration and Development, commented "The assay results from drill hole AR-15-49c2 are very significant for the Arrow zone as it highlights intensive mineralization 41 m up-plunge and northeast from hole -44b. The high grade mineralization within both of these world-class holes is characterized by significant accumulations of massive pitchblende that have rock densities ranging from 2.5 to over 5 g/cm3. The implication of such densities and high grade mineralization across this area in the A2 together with the broadening high grade mineralization in A3 is very positive for the resource calculation of Arrow slated for the first half of 2016."
Leigh Curyer, Chief Executive Officer commented, "AR-15-49c2 is another world class hole at the Arrow zone. Our large step outs continue to deliver amazing results on any metric for a uranium discovery in the Athabasca Basin. This has all been accomplished in comparatively very few holes and low cost for a discovery of this nature and it's a credit to the entire team. We have a significant amount of additional work to complete before we can begin to determine the eventual scale of Arrow. With a treasury of $23M, our current and future programs throughout 2016 are well funded to achieve that goal and develop this rapidly emerging world class uranium discovery."
Assays are included in Table 1. A plan map and the A2 and A3 long sections are shown in Figures 1 to 4.

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 gold by fire assay.
