Hole AR-15-58c1 Returns Highest Grade Assays to Date at Arrow with 11.0m at 30.61% U3O8 Including 3.0m at 72.02% U3O8 and 0.5m at 80.52% U3O8
VANCOUVER, Oct. 22, 2015 /CNW/ - NexGen Energy Ltd. (TSX-V: NXE) ("NexGen" or the "Company") is pleased to report assay results for six angled holes from the on-going summer 2015 drilling program on our 100% owned Rook I property, Athabasca Basin, Saskatchewan.
All six holes reported have returned strong assay results over significant widths. Assay results from hole AR-15-58c1 which was drilled 53 m up-dip and southwest of hole AR-15-44b (56.5m at 11.55% U3O8) have confirmed some of the strongest radioactivity results associated with ample dense massive to semi-massive pitchblende in the higher grade A2 sub-zone, which remains open to the southwest. Furthermore, assays from hole -58c1 have also confirmed the presence of significant uranium mineralization in the A4 shear.
Holes AR-15-48c2, AR-15-48c3, AR-15-53c1 and AR-15-53c3 have all returned widespread uranium mineralization in the A2 shear. Hole AR-15-52, which was a 210 m southwest step-out from hole -44b returned strong assays in the A3 shear.
Drill hole locations, and the A2 and A3 long sections are shown in Figures 1 to 4, and assay results are shown in Table 1.
Highlights:
A2 Shear:
- AR-15-58c1 (53 m up-dip and southwest of AR-15-44b) intersected 80.5 m at 2.48% U3O8 (409.0 to 489.5 m) including 15.5 m at 10.01% U3O8, and a second interval of 35.5 m at 9.72% U3O8 (494.5 to 530.0 m) including, 11.0 m at 30.61% U3O8 and 3.0 m at 72.02% U3O8 in the A2 shear;
- Highest grade assay result from Arrow zone to date in AR-15-58c1: 0.5 m at 80.50% U3O8 (512.5 to 513.0 m);
- AR-15-48c3 (55 m southwest from AR-15-44b) intersected 9.5 m at 4.11% U3O8 (552.5 to 562.0 m), 4.5 m at 7.03% U3O8 (494.5 to 530.0 m) and 10.5 m at 7.30% U3O8 (615.0 to 625.5 m) in the A2 shear.
A3 Shear:
- AR-15-52 (210 m southwest step-out from AR-15-44b) intersected 18.0 m at 1.48% U3O8 (751.5 to 769.5 m) in the A3 shear;
- Assays confirm strong uranium grades in the A3 shear, where hole -52 currently defines the southwest extent of the A3 high-grade core which currently has a total strike length of 295 m and remains open in all directions and at depth.
A4 Shear:
- AR-15-58c1 (53 m up-dip and southwest from AR-15-44b) intersected 5.0 m at 7.23% U3O8 (875.0 to 880.0 m) and 19.0 m at 2.01% U3O8 (883.0 to 902.0 m) in the newly discovered A4 shear;
- The land-based and basement hosted Arrow zone currently covers an area of 645 m by 235 m with a vertical extent of mineralization commencing from 100 m to 920 m, and remains open in all directions and at depth.
- The further expanded, over 30,000 m summer drill program continues and is expected to conclude by the end of October;
- The Company has cash on hand of approximately $20M
Garrett Ainsworth, Vice-President, Exploration and Development, commented "Assay results from hole AR-15-58c1 in the higher grade sub-zone of the A2 shear stand out on a global stage. The sub-vertical dipping and sub-horizontal plunging orientation of this A2 sub-zone are now represented by assays from drill holes -30, -44b, -49c2 and -58c1, which all demonstrate strong continuity and grades that are constantly in excess of 10% U3O8 over wide intervals. In addition, exceptional results in other sections of the A2, A3 and A4 shears are demonstrating that the growth of Arrow continues to develop at speed."
Leigh Curyer, Chief Executive Officer commented, "This latest batch of assay results are very exciting for the project. We expect the higher grade A2 sub-zone on its own will have a material impact on our maiden resource estimate scheduled for the first half of 2016. In addition, the broader A2, A3 and A4 shears are exhibiting high-grade uranium intercepts throughout that continue to increase the known limits of mineralization. Arrow is shaping up to be a truly unique uranium asset, and one that we continue to rigorously test."

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 gold by fire assay.
