VANCOUVER, Jan. 15, 2018 /CNW/ – NexGen Energy Ltd. (“NexGen” or the “Company”) (TSX:NXE, NYSE MKT:NXE) is pleased to report assay results for the final thirty-one holes from South Arrow as part of our recently concluded summer drilling program on our 100% owned, Rook I property, in the Athabasca Basin, Saskatchewan.
All assay results from the recently discovered shallow mineralization at South Arrow have been returned and interpreted. Located just 400 m south of the Arrow Deposit, South Arrow consists of a series of sub-parallel stacked mineralized shears locally anchored by accumulations of semi-massive to massive pitchblend where uranium mineralization has been intersected over a strike length of 290 m.
South Arrow Highlights
1.
AR-17-166c1 intersected 20.5 m at 1.19% U3O8 (182.0 to 202.5 m) including 3.5 m at 6.21% U3O8 (191.5 to 195.0 m) and an additional 24.5 m at 1.46% U3O8 (212.5 to 237.0 m) including 5.0 m at 4.21% U3O8 (221.0 to 226.0 m) and 4.0 m at 3.33% U3O8 (229.5 to 233.5 m)
2.
AR-17-160c1 intersected 13.0 m at 2.18% U3O8 (221.5 to 234.5m) including 4.0 m at 6.79% U3O8 (227.0 to 231.0 m) and an additional 19.5 m at 0.34% U3O8 (191.5 to 211.0 m) including 4.0 m at 1.01% U3O8 (201.5 to 205.5 m).
3.
AR-17-163c1 intersected 22.5 m at 1.07% U3O8 (241.0 to 263.5m) including 3.9 m at 5.56% U3O8 (256.4 to 260.3 m).
4.
AR-17-178c1 intersected 11.0 m at 2.17% U3O8 (149.0 to 160.0 m) including 3.5 m at 6.73% U3O8 (150.5 to 154.0 m) only 142 m below surface.
Drill hole locations and a South Arrow long section are shown in figures 1 and 2.
Development, Activities & Financial
- Assay results for the final 28 drill holes from the Arrow Deposit remain pending.
- Multiple pre-feasibility stage technical studies, including geotechnical work, hydrogeological work, and metallurgy, continue in advance of the maiden Pre-Feasibility Study to be published in Q3/2018.
- The winter 2018 exploration and development program is scheduled to commence in the coming weeks.
- The Company has cash on hand of approximately $160 million.
Garrett Ainsworth, Vice-President, Exploration and Development, commented: “These South Arrow assay results confirm multiple high grade uranium mineralized shears encompassed within a robust alteration halo. Mineralization at South Arrow has been encountered over a strike length of 290 m and a vertical extent of approximately 300 m and remains open in most directions. Taking into consideration the size and extent of the alteration halo surrounding uranium mineralization, results of geochemistry and the clay analysis which shows a strong presence of pathfinder elements, additional drilling is planned during winter 2018 at South Arrow.”
Leigh Curyer, Chief Executive Officer, commented: “Given the uranium grades and geological setting, South Arrow continues to represent exciting exploration potential for NexGen. Additional drilling is planned for winter 2018 to extensively test South Arrow together with multiple other high priority targets generated through 2017 geophysical studies conducted to the south west of Arrow and South Arrow along the prolific Patterson Corridor.”

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 South Arrow 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 Mtonnes 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.
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 I 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. The Rook I Technical Report is available for review under the Company’s profile on SEDAR at www.sedar.com.
U.S. investors are advised that while the terms “indicated resources” and “inferred resources” are recognized and required by Canadian regulations, the U.S. Securities and Exchange Commission does not recognize these terms.
