NexGen Returns Strongest Assay to Date in the A3 Shear with 10.5m at 8.52% U3O8 and 37.0m at 6.30% U3O8

VANCOUVER, Jan. 11, 2016 /CNW/ - NexGen Energy Ltd. ("NexGen" or the "Company") (TSXV:NXE, OTCQX:NXGEF) is pleased to report assay results from an additional six angled drill holes from the highly successful summer 2015 program on the 100% owned, Rook I property, Athabasca Basin, Saskatchewan.  

Assays from hole AR-15-61c2 represent the best returned from the A3 shear to date, with strong uranium grades in two separate and wide intersections, including 10.5 m at 8.52 U3O8 and an additional interval of 37.0 m at 6.30% U3O8 including 15.0 m at 10.10% U3O8. This second interval represents a continuous grade x thickness ("GT") of 236 which is the best to date in the A3 shear.  Hole AR-15-59c3 also intersected high-grade uranium mineralization at the currently defined southwest extent of the A3 shear including 4.5 m at 13.17% U3O8.

High-grade uranium intercepts in the A3 shear from holes AR-15-61c2 and -59c3 are open and represent top priority drill targets for the 30,000 m winter 2016 drill program (see News Release dated January 7, 2016 for further details on winter 2016 drilling).

AR-15-62 which intersected 30.35 m of off-scale radioactivity (>10,000 to >61,000 cps) in the higher grade A2 sub-zone (see News Release dated October 29, 2015) is the only hole that has assay results pending from the summer 2015 program. 

Drill hole locations, and the A2 and A3 long sections are shown in Figures 1 to 3, and assay results are shown in Table 1.

Highlights:

A3 Shear

  • AR-15-61c2 (245 m down-dip and to the southwest from AR-15-48c1) intersected 10.5 m at 8.52% U3O8 (773.5 to 784.0 m), and a separate interval of 37.0 m at 6.30% U3O8 (804.0 to 841.0 m) including 15.0 m at 10.10% U3O8 (826.0 to 841.0 m).
  • Hole AR-15-61c2 returns a continuous GT of 236, which is the highest to date within the A3 shear.
  • AR-15-59c3 (230 m down-dip and to the southwest from AR-15-48c1) intersected 4.5 m at 13.17% U3O8 (668.5 to 673.0 m).
  • AR-15-61c1 (67 m up-plunge to the northeast of AR-15-52) intersected 14.0 m at 3.57% U3O8 (718.5 to 732.5 m).
  • AR-15-60c2 (275 m down-dip and to the northeast from AR-15-48c1) intersected 10.0 m at 2.49% U3O8 (842.5 to 853.0 m).

A2 Shear

  • AR-15-60c2 (165 m down-dip and to the northeast from AR-15-44b) intersected 23.0 m at 1.15% U3O8 (650.0 to 673.0 m).

Arrow, Activities & Financial

  • 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 winter 2016 program comprising 30,000 m of drilling has now commenced with six rigs.
  • The release of a maiden NI 43-101 resource estimate on the Arrow zone is scheduled for the first half of 2016.
  • The company has cash on hand of approximately $34M.

Garrett Ainsworth, Vice-President, Exploration and Development, commented: "We are at an exciting time in the development of the Arrow zone, as we continue to discover and prove up significant high-grade mineralization within multiple shear zones.  Hole AR-15-61c2 has returned a continuous GT of 236 from 37.0 m at 6.30% U3O8, which is the highest continuous GT in the A3 to date.  The A3 shear has developed into an important component of Arrow, hosting multiple drill holes with mineralized intercepts greater than 100 GT.  Further testing of the A3 shear will continue during the winter 2016 drill program."

Leigh Curyer, Chief Executive Officer, commented: "Intersecting the best hole to date in the A3 shear in one of the last holes of the summer 2015 program leads NexGen into a very exciting winter 2016 drill season.  The team looks forward to continuing to develop these higher grade zones now identified within the A3 shear along with a number of other 2016 drill program objectives within all shears and outside the currently defined extents of the Arrow zone."
