Hole AR-16-63c2 Returns a Total Composite GT of 1,329 and Expands Higher Grade A2 Sub-Zone

 

VANCOUVER, March 8, 2016 /CNW/ - NexGen Energy Ltd. ("NexGen" or the "Company") (TSXV:NXE) is pleased to report assay results for five angled holes from our winter 2016 drilling program on our 100% owned, Rook I property, Athabasca Basin, Saskatchewan.

Hole AR-16-63c2 has intersected 42.0 m at 15.20% U3O8 and an additional 46.5 m at 12.99% U3O8 in the higher grade A2 sub-zone (the "Sub-Zone"). When including the 3.5 m of un-mineralized core separating the two mineralized intervals, the hole returned 92.0 m at 13.51% U3O8. This represents a grade x thickness ("GT") of 1,243.

In addition to AR-16-63c2, holes AR-16-63c1, -64c1 and -64c2 intersected continuous GT's in the Sub-Zone of 203, 338 and 541, respectively. These four holes have significantly expanded the current A2 high grade domain. 

The A2 high grade domain is quantified up to the end of the summer 2015 drill program with a recently completed National Instrument 43-101 compliant Inferred Mineral Resource estimate of 120.5 M lbs of U3O8 contained in 0.41 M tonnes grading 13.26% U3O8, which is part of the total Arrow Deposit Inferred Mineral Resource estimate of 201.9 M lbs of U3O8 contained in 3.48 M tonnes grading 2.63% U3O8 (see news release dated March 3, 2016). None of the holes announced in this news release were included in the resource estimate.

Highlights:

A2 Sub-Zone

  • AR-16-63c2 (19 m up-dip and to the southwest from AR-15-44b) intersected 42.0 m at 15.20% U3O8 (458.0 to 500.0 m) including 7.0 m at 52.91% U3O8 (488.5 to 495.5 m) and an additional 46.5 m at 12.99% U3O8 (503.5 to 550.0 m) including 4.0 m at 53.48% U3O8 (530.0 to 534.0 m).
  • AR-16-64c2 (30 m up-dip and to the northeast from AR-15-44b) intersected 48.5 m at 11.15% U3O8 (491.0 to 539.5 m) including 3.0 m at 52.35% U3O8 (498.5 to 501.5 m).
  • AR-16-64c1 (21 m up-dip and to the southwest from AR-15-49c2) intersected 48.5 m at 6.97% U3O8 (433.5 to 482.0 m) including 3.0 m at 52.13% U3O8 (469.0 to 472.0).
  • AR-16-63c1 (7 m up-dip and to the northeast from AR-15-58c1) intersected 45.0 m at 4.51% U3O8 (432.5 to 477.5 m) including 8.0 m at 20.15% U3O8 (464.5 to 472.5 m).

Arrow, Activities & Financial

  • The land-based and basement hosted Arrow Deposit currently covers an area of 670 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 winter 2016 program comprising 30,000 m of drilling continues with six rigs.
  • The Company remains on track for release of an updated NI 43-101 resource estimate on the Arrow Deposit due in the second half of 2016
  • The Company has cash on hand of approximately $31M.

A three-dimensional view of the A2 Sub-Zone, drill hole locations and the A2 and A3 long sections are shown in figures 1 to 5. Table 2 shows assay results.

Garrett Ainsworth, Vice-President, Exploration and Development, commented "The commencement of infill drilling of the higher grade A2 sub-zone has immediately returned five continuous GT's ranging from 203 to 638 in four holes.  These high grade assay intervals from holes AR-16-63c2 and -64c2 extend outside the current A2 high grade shell, on which the maiden NI43-101 inferred mineral resource was estimated as it only incorporates up to hole AR-15-62.  Denser spaced drilling of the A2 sub-zone continues."

Leigh Curyer, Chief Executive Officer commented "This winter 2016 program at such an early stage is clearly becoming our most successful to date. The development of Arrow continues rapidly."
