VANCOUVER, Dec. 11, 2017 /CNW/ - NexGen Energy Ltd. ("NexGen" or the "Company") (TSX:NXE, NYSE MKT:NXE) is pleased to report assay results for 21 holes from Arrow as part of our recently concluded summer drilling program on our 100% owned, Rook I property, in the Athabasca Basin, Saskatchewan.
A3 Infill Drilling
- AR-17-147c3 intersected 60.0 m at 3.70% U3O8 (597.5 to 657.5 m) including 33.0 m at 6.51% U3O8 (607.0 to 640.0 m) and 6.0 m at 17.68% U3O8 (634.0 to 640.0 m). This is the best assay to date at the Arrow Deposit in the A3 Shear.
- AR-17-155c2 intersected 18.5 m at 4.32% U3O8 (560.5 to 579.0 m) including 7.0 m at 11.23% U3O8 (562.0 to 569.0 m) in the A3 shear.
- AR-17-147c2 intersected 28.5 m at 1.74% U3O8 (604.0 to 632.5 m) including 5.5 m at 8.56% U3O8 (605.0 to 610.5 m) in the A3 shear.
Step-Out Drilling
Assays from step-out drilling in both the Southwest and Northeast 'Gaps' confirms mineralization is now known to be continuous in both of these resource expansion areas.
Southwest Gap Step-Outs
- AR-17-156c1 intersected 32.5 m at 1.04% U3O8 (670.5 to 703.0 m) including 9.0 m at 2.72% U3O8 (676.5 to 685.5 m) in the Southwest Gap.
Northeast Gap Step-Outs
- AR-17-129c5 intersected 3.5 m at 3.37% U3O8 (757.5 to 761.0 m) and 8.0 m at 1.54% U3O8 (766.0 to 774.0 m) and 23.5 m at 0.97% U3O8 (851.5 to 875.0 m) in the Northeast Gap.
- AR-17-129c7 intersected 13.0 m at 1.63% U3O8 (783.0 to 796.0 m) including 5.5 m at 3.80% U3O8 (783.0 to 788.5 m) in the Northeast Gap.
Drill hole locations and long sections are shown in Figures 1 to 3.
Development, Activities & Financial
- Assay results for 28 holes at the Arrow Deposit and 31 holes from South Arrow remain pending.
- Multiple advanced-stage technical studies including geotechnical work, hydrogeological work, and metallurgy continue in advance of the maiden Pre-Feasibility Study scheduled to be published in Q3/2018.
- Planning for winter 2018 development and exploration program is advanced.
- The Company has cash on hand of approximately $165 million.
Garrett Ainsworth, Vice-President, Exploration and Development, commented: "These Arrow drill assays are impressive results for both the A3 High Grade Domain infill and resource expansion areas in the Southwest and Northeast Gaps. The A3 High Grade Domain is developing very nicely and the continuation of mineralization along both strike directions continues to show significant drilling is required to determine the extent of the mineralized Arrow footprint. "
Leigh Curyer, Chief Executive Officer, commented: "Arrow's growth continues. Together, the project development studies are advancing for the release of a Pre-Feasibility Study scheduled for Q3 2018. The project development team has recently expanded with the appointment of high calibre industry professionals reflecting the nature of the Arrow Project as a unique opportunity to contribute to this generational mineral resource. The Company is well positioned to enter 2018 and looking forward to delivering the next stages of exploration growth and project development."

Parameters:
- Maximum internal dilution 2.0 m downhole
- Minimum thickness of 0.5 m downhole
- Cutoff grade 0.01% U3O8
- All depths and intervals are metres downhole, true thicknesses are yet to be determined. Resource modelling in conjunction with an updated mineral resource estimate is required before true thicknesses can be determined.
- 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 were taken systematically, and intervals were submitted to SRC Geoanalytical Laboratories (an SCC ISO/IEC 17025: 2005 Accredited Facility) of Saskatoon for analysis. For non-infill holes, samples were analyzed using ICP-MS for trace elements on partial and total digestions (non-radioactive samples), ICP-OES for major and minor elements on partial and total digestions (radioactive samples), and fusion solution of boron by ICP-OES. All mineralized samples were analyzed for U3O8 by ICP-OES and selected samples were analyzed for gold by fire assay.
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.
