NexGen Energy (NXE-V) June 15, '15 is pleased to report assay results for angled hole AR-15-44b from the successful winter 2015 program at the Arrow zone on our 100% owned Rook I property, Athabasca Basin, Saskatchewan.
AR-15-44b has delivered one of the finest uranium mineralized intersections ever drilled in the Athabasca Basin, and is the most continuously mineralized intersection of any hole drilled at the Arrow zone to date. Assays are presented in Table 1, a plan map of the Arrow zone is shown in Figure 1, long sections of the A2 and A3 high grade core zones are shown in Figure 2 and Figure 3, respectively.
Highlights:
AR-15-44b showcases Arrow as a world-class discovery resulting in a total composite grade thickness ("GT") of 853.55;
56.5 m at 11.55% U3O8 (499.5 to 556.0 m) including 20.0 m at 20.68% U3O8 (499.5 to 519.5 m) and 1.0 m at 70.00% U3O8 (503.0 to 504.0 m);
The most continually mineralized intersection at the Arrow zone to date with a GT of 654.78 ranking it as one of the top drill holes ever in uranium exploration;
Located on the current south western edge of the high grade core zones of A2 and A3 shears (see Figure 2 and Figure 3). Summer drilling to step out further to the untested south west;
The Arrow zone is currently 515m by 215m with the vertical extent of mineralization commencing from 100m and extending down to 920m, and is open in all directions (a 90 second 3D video of Arrow generated from Leapfrog is available for viewing on the Company website);
Two of five rigs of the 25,000m $9 Million summer drill program commenced June 8, 2015;
The Company is well financed with working capital of $30 Million.
Garrett Ainsworth, NexGen's Vice-President, Exploration and Development, commented "This world-class result from AR-15-44b will add substantial size to the rapidly developing Arrow zone. When increasing the internal dilution from 2.0 m to 4.5 m, this drill hole returns a total composite interval of 168.5 m at 5.00% U3O8 (455.5 to 624.0 m) representing an estimated true thickness of 43.6 m with only 1.2 m of estimated true thickness internal dilution. The summer 2015 drill program is now underway, and the technical team is excited to continue delineating and expanding the high grade Arrow zone, together with testing the high priority regional geophysical targets."
Leigh Curyer, Chief Executive Officer commented, "AR-15-44b represents a landmark hole and places Arrow into an exclusive class of uranium discoveries on the global stage. Intersecting extensive and high grade mineralization of this magnitude on the south western edge of the current known mineralized zone at Arrow has opened up the potential size and scale of the project to a whole new level. The success rate at Arrow is a result of the diligent work of the technical team led by Garrett Ainsworth and is a credit to all involved".

Composite parameters:
Minimum thickness 0.5 m downhole Cutoff grade 0.01% U3O8 (weight %) Maximum internal dilution 2.00 m downhole U3O8 analyzed by ICP-OES at SRC laboratories, Saskatoon All depths and intervals are meters downhole
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 the partial and total digestions, ICP-OES for major and minor elements on the total digestion, and fusion solution of boron by ICP-OES. Mineralized samples were analyzed for U3O8 by ICP-OES and gold by fire assay.
