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:

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."

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 selected samples for gold by fire assay.

All assay batches reported herein are subjected to and have passed rigorous internal QA/QC protocols that include, but are not limited to, the blind  insertion of standard reference materials, blank materials and field duplicates into the sample stream at both random and systematic intervals.

Generally, but not always, forward-looking information and statements can be identified by the use of words such as "plans", "expects", "is expected", "budget", "scheduled", "estimates", "forecasts", "intends", "anticipates", or "believes" or the negative connotation thereof or variations of such words and phrases or state that certain actions, events or results "may", "could", "would", "might" or "will be taken", "occur" or "be achieved" or the negative connation thereof.

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, uncertainty of mineral resource estimate, pending assay results may not be consistent with preliminary results, 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.
