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 drillingAssays 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

  • 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.

Technical Information

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.

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.

All scientific and technical information in this news release has been prepared by or reviewed and approved by Mr. Garrett Ainsworth, P.Geo., Vice President – Exploration & Development for NexGen. Mr. Ainsworth is a qualified person for the purposes of National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101"), and has verified the sampling, analytical, and test data underlying the information or opinions contained herein by reviewing original data certificates and monitoring all of the data collection protocols.

For details of the Rook I Project including the quality assurance program and quality control measures applied and key assumptions, parameters and methods used to estimate the mineral resource please refer to the technical report entitled "Technical Report on the Preliminary Economic Assessment of the Arrow Deposit, Rook 1 Property, Province of Saskatchewan, Canada" dated effective September 1, 2017 (the "Rook 1 Technical Report") prepared by Jason J. Cox, David M. Robson, Mark B. Mathisen, David A. Ross, Val Coetzee and Mark Wittrup, each of whom is a "qualified person" under NI 43-101.
