NexGen Returns 36.5m at 10.11% U3O8 including 3.5m at 52.33% U3O8 on the Currently Defined Southwest Extent of the Higher Grade A2 Sub-Zone

VANCOUVER, Jan. 5, 2016 NexGen Energy Ltd. ("NexGen" or the "Company") (TSXV:NXE, OTCQX:NXGEF) is pleased to report assay results from an additional seven angled drill holes from our highly successful summer 2015 program on our 100% owned, Rook I property, Athabasca Basin, Saskatchewan.

All seven holes reported have returned significant and extensive uranium mineralization. Most notably, AR-15-59c2 intersected 36.5 m at 10.11% U3O8 including 3.5 m at 52.33% U3O8 which represents another world-class intersection from the higher grade A2 sub-zone (the "Sub-Zone", see Figure 2). Hole -59c2 was drilled at the currently defined southwest extent of this continuously mineralized Sub-Zone which spans 203 m in strike length, begins at less than 400 m below surface and remains open in all directions.  The Sub-Zone will be one of a number of top priorities in the winter 2016 drill program set to commence imminently.

In addition, holes AR-15-54c4 and AR-15-56c2 intersected significant intervals of uranium mineralization across substantial widths in the A

2 and A3 shears, respectively. Both shears remain open in all directions, which presents an exciting growth opportunity for the Arrow zone during the winter 2016 drill program.

Assay results from a further seven holes from the summer 2015 program remain pending including holes AR-15-61c2 which intersected 21.2 m of off-scale radioactivity (>10,000 to >61,000 cps) in a formerly undrilled area of the A3 shear, and AR-15-62 which intersected 30.35 m of off-scale radioactivity in the Sub-Zone (see News Release dated October 29, 2015).

Drill hole locations and the Sub-Zone, A2 and A3 long sections are shown in Figures 1 to 4.  Angled drill hole results from the Sub-Zone are in Table 1, and assay results are shown in Table 2.

Highlights:

A2 Shear

  • AR-15-59c2 (130 m up-dip and to the southwest from AR-15-44b) intersected 36.5 m at 10.11% U3O8 (495.0 to 531.5 m) including 14.5 m at 20.38% U3O8 (517.0 to 531.5 m) including 3.5 m at 52.33% U3O8 (526.5 to 530.0 m) all within the Sub-Zone.
  • AR-15-54c4 (125 m down-dip and to the southwest from AR-15-44b) intersected 9.5 m at 6.93% U3O8 (694.5 to 704.0 m) in the A2 high-grade shear.

A3 Shear

  • AR-15-56c2 (218 m down-dip from AR-15-48c1) intersected 32.0 m at 1.58% U3O8 (746.0 to 778.0 m) in the A3 shear.

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 commencement of a 30,000 m winter 2016 drill program is scheduled for early January 2016.
  • 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: "These batch of assay drill results continue to showcase the world-class nature of the Arrow zone, which is highlighted here by hole AR-15-59c2 returning 36.5m at 10.11% U3O8 at the currently defined southwest boundary of the higher grade A2 sub-zone.  The rapid development of this zone during the summer 2015 drill program has been a huge success at Arrow. To discover the continuously mineralized higher grade A2 sub-zone whilst systematically testing the shear, highlights the potential for the discovery of additional higher grade sub-zones."  

Leigh Curyer, Chief Executive Officer, commented: "The success at Arrow in the summer of 2015, evident by this latest batch of drill results, continues to make the case for Arrow being one of the most exciting uranium projects on the world-stage.  We look forward to commencing our 30,000 m winter 2016 drill campaign at Rook I in early January which will focus on extensions of mineralization to the southwest and northeast of the Arrow zone, the higher grade A2 sub-zone, the Bow Discovery, and other high priority Rook I regional targets."

Such forward-looking information and statements are based on numerous assumptions, including among others, that the results of planned exploration activities are as anticipated, the price of uranium, the anticipated cost of planned exploration activities, that general business and economic conditions will not change in a material adverse manner, that financing will be available if and when needed and on reasonable terms, and that third party contractors, equipment and supplies and governmental and other approvals required to conduct the Company's planned exploration activities will be available on reasonable terms and in a timely manner. Although the assumptions made by the Company in providing forward-looking information or making forward-looking statements are considered reasonable by management at the time, there can be no assurance that such assumptions will prove to be accurate.

Forward-looking information and statements also involve known and unknown risks and uncertainties and other factors, which may cause actual events or results in future periods to differ materially from any projections of future events or results expressed or implied by such forward-looking information or statements, including, among others: negative operating cash flow and dependence on third party financing, uncertainty of additional financing, no known mineral reserves or resources, pending assay results may not be consistent with preliminary results, discretion in the use of proceeds, alternative sources of energy, aboriginal title and consultation issues, reliance on key management and other personnel, potential downturns in economic conditions, actual results of exploration activities being different than anticipated, changes in exploration programs based upon results, availability of third party contractors, availability of equipment and supplies, failure of equipment to operate as anticipated; accidents, effects of weather and other natural phenomena and other risks associated with the mineral exploration industry, environmental risks, changes in laws and regulations, community relations and delays in obtaining governmental or other approvals.

Although the Company has attempted to identify important factors that could cause actual results to differ materially from those contained in the forward-looking information or implied by forward-looking information, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no assurance that forward-looking information and statements will prove to be accurate, as actual results and future events could differ materially from those anticipated, estimated or intended. Accordingly, readers should not place undue reliance on forward-looking statements or information.  The Company undertakes no obligation to update or reissue forward-looking information as a result of new information or events except as required by applicable securities laws.
