VANCOUVER, Feb. 2, 2016 /CNW/ - NexGen Energy Ltd. ("NexGen" or the "Company") (TSXV:NXE, OTCQX:NXGEF) is pleased to announce the first results from our highly anticipated 30,000 m winter 2016 drilling program on our 100% owned Rook I Property, Athabasca Basin, Saskatchewan.
All four angled holes reported in this news release have intersected significant amounts of visible uranium mineralization and off-scale radioactivity highlighted by hole AR-16-64c2 which intersected broad intervals of very dense massive pitchblende mineralization in the higher grade A2 sub-zone (the "Sub-Zone"). Near continuous off-scale radioactivity was measured over a 27.2 m section and also featured 5.5 m measuring a minimum of greater than 61,000 cps in hole -64c2. This represents the most radioactivity with a minimum reading of greater than 61,000 cps ever drilled in any hole at Arrow and further validates the Company's thesis that the Sub-Zone is comprised of continuous accumulations of massive to semi-massive pitchblende mineralization across the currently defined 203 m strike length. The Sub-Zone remains open in all directions.
Furthermore, in the A3 shear, hole AR-16-59c5 which was drilled 46 m down-dip and southwest from hole AR-15-61c2 (8.52% U3O8 over 10.5 m and 6.30% U3O8 over 37.0 m in the A3 shear) intersected 41.5 m of total composite mineralization including 2.95 m of total composite off-scale radioactivity (>10,000 to 40,000 cps) within a 119.5 m section (723.5 to 843.0 m) further expanding the mineralized footprint in this shear which remains open in all directions.

Arrow, Activities & Financial
Drill hole locations and the Sub-zone long section are shown in Figures 1 and 2. Table 2 has a summary of the mineralized intervals.
Garrett Ainsworth, Vice-President, Exploration and Development, commented, "These first radioactivity results of the winter program are simply exceptional. They highlight the continuity of the higher grade A2 sub-zone, established by substantial massive to semi-massive pitchblende, and consistent true width. Hole AR-16-64c2 has a similar radioactivity profile to AR-15-49c2 (returned continuous GT of 605), except it has more than double the minimum >61,000 cps of 5.5m. Further, the results in the A3 are very exciting with respect to defining the higher grade zones within this shear."
Leigh Curyer, Chief Executive Officer commented, "A terrific start to the 2016, 30,000m six rig winter program. The rapid development of the Arrow zone and exploration of the Rook I property is in top gear and we look forward to delivering the ongoing drill results on the A2 sub-zone, the four shears and more broadly, along strike from Arrow."

Parameters:
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 not 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-16-59c5
Hole AR-16-59c5 was a directional hole that was wedged from AR-15-59c4 at a depth of 192 m. It tested the A2 shear 54 m down-dip of AR-15-61c1 and the A3 shear 46 m down-dip and southwest of AR-15-61c2 (8.52% U3O8 over 10.5 m and 6.30% U3O8 over 37.0 m in the A3 shear). Directional drilling was initiated at 213 m. The A2 and A3 shears were intersected at inclinations of -73° and -70°, respectively.
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 and A3 shears). The hole successfully intersected weakly to strongly anomalous radioactivity in the A2 and A3 shears that was associated with stringers, worm-rock style, chemical solution fronts, blebs and flecks of pitchblende. A total composite mineralization of 67.0 m including 3.05 m of off-scale radioactivity (>10,000 - 40,000 cps) was intersected within a 356.5 m section (543.5 to 900.0 m). In the A2 shear, 25.0 m of composite mineralization including 0.1 m of off-scale radioactivity was intersected. In the A3 shear 41.5 m of composite mineralization including 2.95 m of off-scale radioactivity was intersected. The hole was terminated following the A3 shear at 915 m. It represents successful step-outs on both the A2 and A3 shears.
AR-16-63c1
Hole AR-16-63c1 was a directional hole collared from surface at an angled orientation (-74°) to the southeast (156° azimuth). It tested the A2 shear 7 m up-dip and northeast of AR-15-58c1 (2.48% U3O8 over 80.5 m and 9.72% U3O8 over 35.5 m in the A2 shear). Directional drilling was initiated at 288 m. However due to poor ground conditions, an optimal hole orientation could not be achieved and the planned A2 pierce point was missed by 7 m. The A2 shear was intersected at an inclination of -71°.
The hole intersected bleached Athabasca Group sandstones between 96.0 m and the unconformity at 109.1 m. Basement lithologies consisted largely of semipelitic gneiss to granofel, and relatively narrow intervals of pelitic gneiss and mylonite (the A2 shear). The hole successfully intersected weakly to strongly anomalous radioactivity within the higher grade sub-zone of the A2 shear that was associated with semi-massive to massive veins, stringers, worm-rock style, chemical solution fronts, blebs and flecks of pitchblende. The most intense mineralization was characterized by the presence of dense accumulations of massive pitchblende. A total composite mineralization of 55.5 m including 7.35 m of off-scale radioactivity (>10,000 - >61,000 cps) was intersected within a 112.5 m section (433.0 to 545.5 m), all within the A2 shear. The hole was terminated immediately following the A2 shear at 592 m.
AR-16-64c1
Hole AR-16-64c1 was a directional hole collared from surface at an angled orientation (-73°) to the southeast (154° azimuth). It tested the A2 shear 21 m up-dip and to the southwest of AR-15-49c2 (8.77% U3O8 over 69.0 m in the A2 shear) and the A3 shear 24 m down-dip and northeast of AR-15-48c1 (5.43% U3O8 over 24.0 m). The A2 and A3 shears were both intersected at an inclination of -63°.
The hole intersected intensely desilicified and bleached Athabasca Group sandstones between 85.0 m and the unconformity at 108.0 m. Basement lithologies consisted largely of semipelitic gneiss to granofel, and relatively narrow intervals of pelitic gneiss and mylonite (the A2 and A3 shears). The hole successfully intersected weakly to strongly anomalous radioactivity within the higher grade sub-zone of the A2 shear and A3 shear that was associated with semi-massive to massive veins, stringers, worm-rock style, chemical solution fronts, blebs and flecks of pitchblende. Of particular note, dense accumulations of massive pitchblende were intersected within three discrete veins in the A2 shear. A total composite mineralization of 127.5 m including 19.0 m of off-scale radioactivity (>10,000 - >61,000 cps) was intersected within a 261.5 m section (433.5 to 695.0 m). In the A2 shear, 74.0 m of composite mineralization including 14.0 m of off-scale radioactivity was intersected. In the A3 shear, 49.5 m of composite mineralization including 4.3 m of off-scale radioactivity was intersected. The hole was terminated immediately following the A3 shear at 729 m. It confirms the continuity of strong to intense uranium mineralization between previously drilled holes in both the A2 and A3 shears.
AR-16-64c2
Hole AR-16-64c2 was a directional hole that departed pilot hole AR-16-64c1 at a depth of 213 m. It tested the A2 shear 29 m up-dip and northeast of AR-15-44b (11.55% U3O8 over 56.5 m in the A2 shear). Directional drilling was initiated at 312 m and the A2 shear was intersected at an inclination of -66°.
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 A2 shear that featured dense accumulations of massive pitchblende. A total composite mineralization of 76.0 m including 26.15 m of off-scale radioactivity (>10,000 - >61,000 cps) was intersected within a 165.5 m section (414.0 to 579.5 m), all within the A2 shear. Of important note, a 27.2 m section of drill core (496.8 to 524.0 m) consisted of nearly continuous off-scale radioactivity. The hole was terminated following the A2 shear at 591 m. It represents another world-class intersection in the higher grade sub-zone of the A2 shear.
AR-16-65
Hole AR-16-65 was a vertical hole designed to test the unconformity for flat lying uranium mineralization. The hole intersected intensely desilicified Athabasca Group sandstones between 87.0 m and the unconformity at 102.8 m. The basement consisted entirely of hematite and clay altered semipelitic gneiss. Although heavily altered sandstone was observed no anomalous radioactivity was intersected and the hole was terminated at 150.0 m.
AR-16-66
Hole AR-16-66 was a vertical hole designed to test the unconformity for flat lying uranium mineralization. The hole intersected moderately desilicified and bleached Athabasca Group sandstones between 90.0 m and the unconformity at 95.0 m. The basement consisted entirely of locally intensely clay altered semipelitic gneiss. Anomalous radioactivity of up to 680 cps (RS-125 scintillometer) was intersected between 155.0 and 155.5 m. The hole was terminated at 183.0 m.
AR-16-67
Hole AR-16-67 was a vertical hole designed to test the unconformity for flat lying uranium mineralization. The hole intersected moderately to strongly bleached and hematite altered Athabasca Group sandstones between 78.6 m and the unconformity at 90.95 m. The basement consisted entirely of hematite and clay altered semipelitic gneiss. Although no anomalous radioactivity was observed in the recovered core, down hole gamma probe results (2PGA-1000 gamma probe) showed anomalous radioactivity between 79.56 m and 80.26 m at or very near the Devonian-Athabasca unconformity where a peak of up 566 cps was measured. This interval was not recovered during drilling, which suggests heavy alteration. The hole was terminated at 150.0 m.
AR-16-68
Hole AR-16-68 was a vertical hole designed to test the unconformity for flat lying uranium mineralization. The hole intersected strongly to intensely bleached and desilicified Athabasca Group sandstones between 77.05 m and the unconformity at 87.0 m. The basement consisted of strongly hematite and clay altered semipelitic gneiss. The hole was abandoned due to poor ground conditions at 92.1 m. No anomalous radioactivity was intersected.
AR-16-69
Hole AR-16-69 was a re-collar of AR-16-68. The hole intersected bleached Athabasca Group sandstones between 77.05 m and the unconformity at 88.1 m. The basement consisted of moderately to strongly hematite and clay altered semipelitic gneiss. No anomalous radioactivity was intersected and the hole was terminated at 150.0 m.
AR-16-70
Hole AR-16-70 was a vertical hole designed to test the unconformity for flat lying uranium mineralization. The hole intersected moderately bleached and intensely desilicified Athabasca Group sandstones between 76.9 m and the unconformity at 92.9 m. The basement consisted of moderately to strongly hematite and clay altered semipelitic gneiss. No anomalous radioactivity was intersected and the hole was terminated at 150.0 m.
