NexGen Drills Most Intense Mineralization to Date at Arrow

VANCOUVER, Feb. 9, 2016 /CNW/ - NexGen Energy Ltd. ("NexGen" or the "Company") (TSXV:NXE, OTCQX:NXGEF) is pleased to announce further results from our on-going six rig 30,000 m winter 2016 drill program on our 100% owned Rook I Property, Athabasca Basin, Saskatchewan.

Hole AR-16-63c2 has drilled the most significant accumulations of massive pitchblende ever encountered at the Arrow zone.  The mineralization, which was intersected 19 m up-dip and southwest of AR-15-44b in the higher grade A2 sub-zone (the "Sub-Zone"), featured 40.85 m of off-scale radioactivity (>10,000 to >61,000 cps) and included 13.85 m at a minimum-of-greater-than-61,000 cps.

The mineralization encountered in hole -63c2 includes the most minimum-of-greater-than-61,000 cps mineralization seen at Arrow and is nearly seven times as much as hole AR-15-62 which is the best hole at the project on a continuous grade x thickness ("GT") basis at 787.  Hole -63c2 was drilled 27 m down-dip and southwest from hole AR-16-64c2 (see News Release dated February 2, 2016).

Highlights:

A2 Shear:

• AR-16-63c2 (19 m up-dip and southwest from AR-15-44b and 14 m down-dip and northeast from AR-15-62) intersected 138.0 m of total composite mineralization including 40.85 m of total composite off-scale radioactivity (10,000 to >61,000 cps) within a 206.5 m section (439.5 to 645.5 m) featuring 13.85 m with a minimum of >61,000 cps in the Sub-Zone. The mineralization was defined by wide intervals of dense accumulations of massive pitchblende (see http://www.nexgenenergy.ca/s/photo-gallery.asp for photos).

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 is now fully operational with six drill rigs active.
• 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 $33M.

Drill hole locations, the Sub-Zone long section and a gamma log profile are shown in Figures 1 through 3. Table 2 has a summary of the mineralized intervals.

Garrett Ainsworth, Vice-President, Exploration and Development, commented: "Results from hole AR-16-63c2 are simply stunning, and represent the strongest radioactivity ever recorded at the Arrow zone.  The continuity of mineralization in the higher grade A2 sub-zone is clearly evident.  Furthermore, this zone remains open and will be tested further this winter together with exploring for other potential 'sub-zones' at Arrow. Hole -63c2 has a similar radioactivity profile to AR-15-62 (returned continuous GT of 787), except it has nearly seven times as much minimum >61,000 cps.  The gamma probe comparison between the two holes really says it all."     

Leigh Curyer, Chief Executive Officer, commented: "The Arrow zone has again delivered a truly unique hole. The winter 2016 program has already produced highly material results in only its first month of operation, highlighting Arrow's current and future potential.  Our six rig program will continue to define the A2 sub-zone further as well as drill for zone extensions and along strike from Arrow."

Table 2: Arrow Zone Drill Hole Data

Parameters:

• Maximum internal dilution 2.00 m downhole
• All depths and intervals are meters downhole
• "Anomalous" means >500 cps (counts per second) total count gamma readings by gamma scintillometer type RS-120
• "Off-scale" means >10,000 cps (counts per second) total count gamma readings by gamma scintillometer type RS-120
• Where "Min cps" is <500 cps, this refers to local low radiometric zones within the overall radioactive interval

Natural gamma radiation in drill core reported in this news release was measured in counts per second (cps) using a Radiation Solutions Inc. RS-120 gamma-ray scintillometer. The reader is cautioned that total count gamma readings may n ot be directly or uniformly related to uranium grades of the rock sample measured; they should be used only as a preliminary indication of the presence of radioactive minerals. All intersections are downhole. True thicknesses are yet to be determined.

Split core samples will be taken systematically, and intervals will be submitted to SRC Geoanalytical Laboratories (an SCC ISO/IEC 17025: 2005 Accredited Facility) of Saskatoon for analysis. All samples sent to SRC will be 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 are analyzed for U₃O₈ by ICP-OES and select samples for gold by fire assay. Assay results will be released when received and after stringent internal QA/QC protocols are passed.

The technical information in this news release has been approved by Garrett Ainsworth, P.Geo., Vice President – Exploration & Development, a qualified person for the purposes of National Instrument 43- 101 – Standards of Disclosure for Mineral Projects. Mr. Ainsworth reviewed the data disclosed in this news release, including the sampling, analytical and test data underlying the information contained in this news release.

ARROW ZONE DRILLING

AR-16-63c2

Hole AR-16-63c2 was a directional hole that departed pilot hole AR-16-63c1 at 292 m. It tested the A2 shear 19 m up-dip and southwest of AR-15-44b (11.55% U₃O₈ over 56.5 m in the A2 shear). Directional drilling was initiated at 303 m and the A2 shear was intersected at an inclination of -73°.

Since the hole departed the pilot hole below the unconformity, no Athabasca Group sandstones were intersected. Basement lithologies consisted largely of semipelitic gneiss to granofel, and relatively narrow intervals of pelitic gneiss and mylonite (the A2 shear). Extensive visible uranium mineralization was intersected in the higher grade sub-zone of the A2 shear that unequivocally featured the heaviest concentrations of massive pitchblende ever drilled at Arrow. A total composite mineralization of 138.0 m including 40.85 m of off-scale radioactivity (>10,000 - >61,000 cps) was intersected within 206.0 m section (439.5 – 645.5 m), all within the A2 shear. Furthermore, an unprecedented 13.85 m of core within the mineralized intersection showed minimum radioactivity in excess of 61,000 cps.
