VANCOUVER, Nov. 30, 2017 /CNW/ – NexGen Energy Ltd. (“NexGen” or the “Company”) (TSX:NXE, NYSE MKT:NXE) is pleased to report radioactivity results for the final forty holes from South Arrow and Arrow as part of our now concluded summer drilling program on our 100% owned, Rook I property, in the Athabasca Basin, Saskatchewan.
Arrow Highlights:
Drilling at Arrow has intersected strong mineralization in multiple areas including step-out holes drilled in key mineral resource expansion areas in the southwest gap, northeast gap and within the A3 shear. The Arrow Deposit remains open in most directions.
A3 Step-Outs
- AR-17-159c1 intersected 44.0 m of total composite mineralization including 13.85 m of total composite off-scale radioactivity (>10,000 to >61,000 cps) within a 90.0 m section (377.0 to 467.0 m) in the A3 shear.
- AR-17-159c2 intersected 54.5 m of total composite mineralization including 11.8 m of total composite off-scale radioactivity (>10,000 to >61,000 cps) within a 101.0 m section (375.5 to 476.5 m) in the A3 shear.
A3 Infill
- AR-17-164c1 intersected 47.5 m of total composite mineralization including 5.0 m of total composite off-scale radioactivity (>10,000 to >61,000 cps) within a 147.0 m section (497.5 to 644.5 m) in the A3 shear.
Northeast Gap Step-Out
- AR-17-171c3 intersected 45.5 m of total composite mineralization including 1.45 m of total composite off-scale radioactivity (>10,000 to 23,000 cps) within a 183.0 m section (749.5 to 932.5 m) in the A1 and A2 shears. The hole is 250 m northeast and down-dip of the mineral resource domains.
Southwest Gap Step-Out
- AR-17-161c2 intersected 30.0 m of total composite mineralization including 1.2 m of total composite off-scale radioactivity (>10,000 to >61,000 cps) within a 314.0 m section (626.5 to 940.5 m) in the A3 though A5 shears. The hole is 54 m southwest and down-dip of the mineral resource domains.
Drill hole locations and longsections are shown in Figures 1 to 4. Drill hole descriptions can be found on our website at www.nexgenenergy.ca
South Arrow Highlights:
Systematic drilling at the recently discovered South Arrow has intersected uranium mineralization at continued shallow depths. South Arrow is comprised of multiple, stacked mineralized horizons and high grade mineralization occurs as accumulations of semi-massive to massive pitchblende similar to the Arrow Deposit. South Arrow remains largely open and off-scale radioactivity has been intersected over a strike length of currently 290 m.
- AR-17-178c1 intersected 7.5 m of total composite mineralization including 1.85 m of total composite off-scale radioactivity (>10,000 to >61,000 cps) within a 170.5 m section (149.0 to 319.5 m). The off-scale mineralized section begins just 142 m below surface.
- AR-17-170c1 intersected 12.0 m of total composite mineralization including 0.5 m of total composite off-scale radioactivity (>10,000 to >26,000 cps) within a 15.0 m section (243.0 to 258.0 m).
- AR-17-174c1 intersected 35.0 m of total composite mineralization including 0.15 m of total composite off-scale radioactivity (>10,000 to >26,600 cps) within a 161.5 m section (225.5 to 387.0 m).
- AR-17-184c1 intersected 11.0 m of total composite mineralization including 0.5 m of total composite off-scale radioactivity (>10,000 to >21,000 cps) within an 11.0 m section (134.0 to 145.0 m).
Development, Activities & Financial:
- The eight drill rig summer development and exploration program has concluded. The program consisted of 82 infill, expansion, exploration and geotechnical holes totaling 44,781 m of diamond drilling. Assays remain pending for all holes. An additional five shallow geotechnical holes were completed with a sonic drill rig to test surface and subsurface conditions for future site infrastructure.
- Planning for the winter 2018 development and exploration program has begun in advance of the maiden Pre-Feasibility Study to be published Q3/2018.
- The Company has cash on hand of approximately $170 million.
Garrett Ainsworth, Vice-President, Exploration and Development, commented: “The summer 2017 drill program objectives have been successfully achieved in balancing indicated resource growth in the A3 High Grade Domain while expanding inferred resource growth at Arrow. The added bonus of discovery and expansion of South Arrow suggests significant potential for resource growth within close proximity to the Arrow Deposit. A recently completed ground 3D resistivity survey over South Arrow focusing to the south west has highlighted the significant prospectivity of the Patterson Corridor along strike from Arrow and South Arrow which is yet to be tested.”
Leigh Curyer, Chief Executive Officer, commented: “The 2017 program has continued to demonstrate Arrow’s resource growth and incredible robustness with drilling inside and outside the 2016 grade shells. The results have provided valuable data with respect to future resource growth opportunities and potential mine development. With assay results pending, plans are well underway for an exciting 2018 targeting continued resource definition and expansion at Arrow and South Arrow, together with advanced development studies leading into the publication of a maiden Pre-Feasibility Study in Q3 2018.”

Parameters:
- Maximum internal dilution 2.00 m downhole
- All depths and intervals are metres downhole, true thicknesses are yet to be determined
- “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
- Directional drilling has often resulted in mineralization intersected at a more favourable and shallower dip

Parameters:
- Maximum internal dilution 2.00 m downhole
- All depths and intervals are metres downhole, true thicknesses are yet to be determined
- “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
- Directional drilling has often resulted in mineralization intersected at a more favourable and shallower dip
About NexGen
NexGen is a British Columbia corporation with a focus on the acquisition, exploration and development of Canadian uranium projects. NexGen has a highly experienced team of uranium industry professionals with a successful track record in the discovery of uranium deposits and in developing projects through discovery to production.
NexGen owns a portfolio of prospective uranium exploration assets in the Athabasca Basin, Saskatchewan, Canada, including a 100% interest in Rook I, location of the Arrow Deposit in February 2014, the Bow discovery in March 2015, the Harpoon discovery in August 2016 and the Arrow South discovery in July 2017. The Arrow deposit’s updated mineral resource estimate with an effective date of December 20, 2016 was released in March 2017, and comprised 179.5 M lbs U3O8 contained in 1.18 M tonnes grading 6.88% U3O8 in the Indicated Mineral Resource category and an additional 122.1 M lbs U3O8 contained in 4.25 M tonnes grading 1.30% U3O8 in the Inferred Mineral Resource category.
