More Great New Go NXENexGen Drills 37.4 m of Off-Scale Expanding the High Grade Domain and Discovers Anomalous Radioactivity 1.3 km Northeast of Arrow 28 minutes ago - ACQUIREMEDIA VANCOUVER, April 18, 2016 /CNW/ - NexGen Energy Ltd. ("NexGen" or the "Company") (TSXV:NXE, OTCQX:NXGEF) is pleased to announce further results from our recently expanded winter-spring drilling program on our 100% owned Rook I Property, Athabasca Basin, Saskatchewan. Drill hole AR-16-78c4 has intersected dense accumulations of massive pitchblende, which has expanded the higher grade A2 sub-zone (the "Sub-Zone") which makes up part of the A2 High Grade Domain (Figure 1, 3 to 6). The mineralization was intersected 59 m down-dip and northeast of AR-15-44b and features 37.4 m of off-scale radioactivity (>10,000 to >61,000 cps). This included 5.5 m at a minimum-of-greater-than 61,000 cps, of which 4.5 m was continuous. On a radioactivity basis, AR-16-78c4 ranks as one of the best holes ever drilled at Arrow. Importantly, the high grade mineralization encountered in hole -78c4 was predominately intersected outside of the current boundary of A2 High Grade Domain (Figure 3). The A2 High Grade Domain hosts a 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 within the total Arrow Deposit Inferred Mineral Resource estimate of 201.9 M lbs U3O8 contained in 3.48 M tonnes grading 2.63% (see news release dated March 3, 2016). The maiden resource estimate on Arrow includes drill holes to October 2015, and does not include the 40 drill holes completed so far in 2016. In addition, anomalous radioactivity sourced from uranium (confirmed with RS-125 spectrometer scintillometer) has been drilled approximately 1.3 km northeast of the Arrow deposit (Figure 2). This new area, named Cannon, is coincident with a gravity low and weakened VTEM conductor. The area has very similar geophysical, lithological and alteration features to the Arrow deposit. To date, 11 holes have been drilled at Cannon, all of which intersected strong-to-intense hydrothermal alteration. Furthermore, 4 holes have intersected anomalous radioactivity of up to 1,300 cps (measured by RS-120 hand-held scintillometer). At least two highly prospective graphitic mylonite shear zones with large envelopes of strong-to-intense clay alteration have been identified. Cannon is open in all directions and is largely untested at the unconformity up-dip from basement structures that host anomalous radioactivity. Highlights: A2 Shear: AR-16-78c4 (59 m down-dip and northeast from AR-15-44b) intersected 120.5 m of total composite mineralization including 37.4 m of total composite off-scale radioactivity (>10,000 >61,000 cps) within a 203.5m section (441.5 to 645.0 m), featuring 4.5 m of continuous mineralization at a minimum of greater than 61,000 cps in the Sub-Zone.

The winter 2016 six drill rig program comprising 30,000 m of drilling is currently transitioning to our spring 2016, 7,500 m of drilling program. The Company has cash on hand of $33M to fund its 2016 programs. Drill hole location maps, a cross section of drill hole AR-16-78c4, and A2 and A3 long sections are shown in Figures 1 to 6. Table 2 has a summary of the mineralized intervals. Garrett Ainsworth, Vice-President, Exploration and Development, commented: "Drilling in the A2 High Grade Domain continues to return exceptional results as shown by the abundant dense accumulations of massive to semi-massive pitchblende in drill hole AR-16-78c4, which has materially expanded this domain. In addition, our regional drilling 1.3 km northeast of the Arrow deposit has discovered anomalous radioactivity at Cannon. This new area confirms the large and robust nature of the uranium mineralizing system responsible for the Arrow deposit and Bow zone which hosts potential for additional discoveries along the Patterson Conductor Corridor." Leigh Curyer, Chief Executive Officer commented: "The objectives for the winter 2016 drilling program have been met on all fronts. Arrow infill drilling continues to confirm the robustness of mineralization with AR-16-78c4 ranking as one of the best radioactive results to date at Arrow. The early signs at Cannon are very encouraging and will be a focus of summer 2016 drill program balanced with continual Arrow infill, zone expansion, and testing to the southwest along the conductor corridor. These results place multiple demands on the available drill rigs and management will continue to systematically allocate meters in an optimal manner within the program objectives."

The hole was terminated at 705 m. AR-16-79 Hole AR-16-79 was a collared from surface at an angled orientation (-70 dip) to the southeast (140 azimuth). It was designed to test for the presence of mineralization 630 m southwest of the Arrow deposit in an area of no previous drilling. The hole intersected 1 m of bleached Athabasca Group sandstones above the unconformity at 85 m. Basement lithologies consisted of largely of semipelitic gneiss to granofel, and relatively narrow intervals of pelitic gneiss, orthogneiss, garnetite and mylonite. Highly prospective graphitic shear zones were intersected over several intervals in the hole which are interpreted to correspond to those that host the Arrow deposit. No anomalous radioactivity was encountered in the hole before it was terminated at 954 m. More drilling is required to fully assess this highly prospective area. AR-16-80c1 Hole AR-16-80c1 was a directional hole collared from surface at an angled orientation (-70 dip) to the southeast (147 azimuth). It tested the A2 shear 23 m up-dip and southwest of AR-15-54c1 (7.03% U3O8 over 39.5 m in the A2 shear) and the A3 shear 28 m down-dip and southwest of AR-15-58c2 (0.61% U3O8 over 9.5 m in the A3 shear). Directional drilling was initiated at 228 m. The A2 and A3 shears were both intersected at an inclination of -63. The hole intersected pervasively bleached and desilicified Athabasca Group sandstones between 90.0 m and the unconformity at 112.2 m. Basement lithologies consisted largely of semipelitic gneiss to granofel, and relatively narrow intervals of pelitic gneiss and mylonite (the A2 through A4 shears). The hole successfully intersected widespread anomalous radioactivity in the A2 through A4 shears that was associated with semi-massive veins, blebs and flecks of pitchblende. A total composite mineralization of 61.0 m including 0.45 m of off-scale radioactivity (>10,000 32,000 cps) was intersected within a 308.5 m section (433.5 to 742.0 m). In the A2 shear, 24.5 m of composite mineralization was intersected including 0.25 m of off-scale radioactivity. In the A3 shear, 27.0 m of composite mineralization was intersected including 0.2 m of off-scale radioactivity. In the A4 shear, 9.5 m of composite mineralization was intersected. The hole was terminated at 792 m. AR-16-80c2 Hole AR-16-80c2 was a directional hole that departed pilot hole AR-16-80c1 at a depth of 231 m. It tested the A2 shear 20 m up-dip and northeast of AR-15-59c2 (5.42% U3O8 over 68.5 m in the A2 shear). Directional drilling was initiated at 243 m and the A2 shear was intersected an inclination of -64. 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). The hole successfully intersected widespread anomalous radioactivity in the A2 shear that was associated with semi-massive to massive veins, stringers, chemical solution fronts, blebs and flecks of pitchblende. A total composite mineralization of 14.5 m including 3.0 m of off-scale radioactivity (>10,000 - >61,000 cps) was intersected within a 72.0 m section (456.0 to 528.0 m) before the hole was terminated at 561 m. AR-16-80c3 Hole AR-16-80c3 was a directional hole that departed pilot hole AR-16-80c2 at 246 m. It tested the A2 shear 26 m up-dip and northeast of AR-15-59c2 (5.42% U3O8 over 68.5 m in the A2 shear). Directional drilling was initiated at 276 m and the A2 shear was intersected at an inclination of -65. 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). The hole successfully intersected widespread anomalous radioactivity in the A2 shear that was associated with stringers, chemical solution fronts, blebs and flecks of pitchblende. A total composite mineralization of 38.5 m including 2.4 m of off-scale radioactivity (>10,000 -45,000 cps) was intersected within a 94.0 m section (450.5 to 544.5 m) before the hole was terminated at 585 m. AR-16-81c1 Hole AR-16-81c1 was a directional hole collared from surface at an angled orientation (-69 dip) to the southeast (145 azimuth). It tested the A2 shear 21 m up-dip and southwest of AR-15-59c2 (5.42% U3O8 over 68.5 m in the A2 shear) and the A3 shear 21 m up-dip and southwest of AR-15-59c1 (0.46% U3O8 over 6.5 m in the A3 shear). Directional drilling was intersected at 249 m. The A2 and A3 shears were both intersected at an inclination of -64. The hole intersected strongly to intensely bleached and desilicified Athabasca Group sandstones between 90.5 and the unconformity at 111.0 m. Basement lithologies consisted largely of semipelitic gneiss to granofel, and relatively narrow intervals of pelitic gneiss and mylonite (the A2 through A4 shears). The hole successfully intersected widespread anomalous radioactivity in the A2 through A4 shears that was associated with stringers, chemical solution fronts, blebs and flecks of pitchblende. A total composite mineralization of 81.5 m including 2.3 m of off-scale radioactivity (>10,000 -56,000 cps) was intersected within a 324.0 m section (474.5 to 798.5 m). In the A2 shear, 22.0 m of composite mineralization was intersected including 1.65 m of off-scale radioactivity. In the A3 shear, 10.0 m of composite mineralization was intersected including 0.15 m of off-scale radioactivity. In the A4 shear, 49.5 m of composite mineralization including 0.5 m of off-scale radioactivity was intersected. The hole was terminated at 850 m. AR-16-82c1 Hole AR-16-82c1 was a directional hole collared from surface at an angled orientation (-75 dip) to the southeast (140 azimuth). It tested the A4 shear as a 120 m up-dip and northeast step-out from AR-16-77c2 (2.3 m of off-scale radioactivity in the A4 shear; assays pending). Directional drilling was initiated at 159.0 m and the A4 shear was intersected at an inclination of -70. Basement lithologies were intersected beginning at 93.0 m which consisted largely of semipelitic gneiss to granofel, and relatively narrow intervals of pelitic gneiss and mylonite (the A2 through A4 shears). No Athabasca Group sandstones were intersected. The hole successfully intersected anomalous radioactivity to southeast of the A4 shear that was associated with stringers of, and fracture-controlled pitchblende mineralization. A total composite mineralization of 3.5 m including 0.25 m of off-scale radioactivity (>10,000 - 14,000 cps) was intersected within a 195.0 m section (604.5 to 799.5 m) before the hole was terminated at 834 m. AR-16-83 Hole AR-16-83 was collared from surface at an angled orientation (-70 dip) to the southeast (140 azimuth). It was collared 125 m southeast of AR-16-79 and designed to test for the presence of mineralization 600 m southwest of the Arrow deposit in an area of no previous drilling. Basement lithologies were intersected beginning at 87.0 m which consisted largely of semipelitic gneiss to granofel, and relatively narrow intervals of pelitic gneiss and mylonite. No Athabasca Group sandstones were intersected. Highly prospective graphitic shear zones were intersected over several intervals in the hole which are interpreted to correspond to those that host the Arrow deposit. No anomalous radioactivity was encountered in the hole before it was terminated at 792 m. More drilling is required to fully assess this highly prospective area. CANNON AREA DRILLING Holes CN-16-01 through CN-16-11 were collared at angled orientations to the northwest, mostly at azimuths of 335 with dips of -70. Athabasca Group sandstones of various thickness were intersected in every hole. Basement lithologies consisted largely of semipelitic gneiss, pelitic gneiss, quartzite and orthogneiss, with relatively narrow intervals of chloritic and graphitic mylonite. All 11 holes intersected strong to intense hydrothermal alteration envelopes typically marked by illite-sudoite-hemaite- mineral assemblages. Holes CN-16-01, -02, -06 and -10 intersected narrow zones of anomalous radioactivity from greater than 300 to 1,300 cps over intervals from 0.5 to 1.5 m of core length, which were in close association with mylonitic shear zones. Note that for regional holes, the Company defines anomalous radioactivity as greater than 300 cps as measured on the drill core by handheld scintillometer (RS-120). The alteration zones remain open in all directions, and at the unconformity, and further drilling is planned for the summer 2016 program.
