NexGen Drills Massive Pitchblende at South Arrow


October 18, 2017

VANCOUVER, Oct. 18, 2017 /CNW/ - NexGen Energy Ltd. ("NexGen" or the "Company") (TSX:NXE, NYSEMKT:NXE) is pleased to report radioactivity results for sixteen holes from South Arrow as part of our on-going summer drilling program on our 100% owned, Rook I property, in the Athabasca Basin, Saskatchewan.

South Arrow

Aggressive step out drilling at the recently discovered South Arrow has intersected significant off-scale radioactivity in multiple holes, and has extended the strike length and vertical extent of high grade mineralization to 240 m and 185 m, respectively. High grade uranium mineralization occurs as accumulations of semi-massive to massive pitchblende similar to that seen in the High Grade Domains of the Arrow Deposit.

  • AR-17-166c1 (250 m up-dip and southwest of discovery hole AR-17-151c1) intersected 41.0 m of total composite mineralization including 6.2 m of total composite off-scale radioactivity (>10,000 to >61,000 cps) within a 54.0 m section (182.5 to 236.5 m). This is the shallowest significant off-scale mineralization encountered anywhere on the Rook I property.
  • AR-17-160c1 (203 m up-dip and southwest of discovery hole AR-17-151c1) intersected 30.0 m of total composite mineralization including 3.5 m of total composite off-scale radioactivity (>10,000 to >61,000 cps) within a 157.0 m section (192.0 to 349.0 m).
  • AR-17-163c1 (190 m up-dip and southwest of discovery hole AR-17-151c1) intersected 23.0 m of total composite mineralization including 2.2 m of total composite off-scale radioactivity (>10,000 to >61,000 cps) within a 109.5 m section (162.5 to 272.0 m).

 

Two diamond drill rigs remain in operation at South Arrow as the Company continues to aggressively and systematically test this encouraging new zone. A total of eighteen assays remain pending.

A South Arrow longitudinal section and plan map with drill hole locations are shown in Figures 1 and 2.

Garrett Ainsworth, Vice-President, Exploration and Development, commented: "Drill hole AR-17-160c1 represents a highly successful 203 m step out to the southwest from the initial discovery hole at South Arrow. The ability to hit high grade mineralization on an aggressive step out of this distance has been a common characteristic of the Arrow Deposit, which is located 400 m to the north of South Arrow on a separate conductor. South Arrow contains a broad alteration halo that surrounds multiple parallel stacked mineralized zones, which are two important features observed at the Arrow Deposit. Hole AR-17-166c1 at South Arrow has encountered the shallowest significant high grade mineralization anywhere on the Rook I property to date."

Leigh Curyer, Chief Executive Officer, commented: "The scale of these South Arrow results are very exciting considering its very early in the discovery stage. They are unprecedented on the Rook I property and highlight the vast discovery potential of our dominant portfolio in the Southwest Athabasca Basin. An additional 5,000m of drilling has been allocated to South Arrow before the conclusion of the 2017 drilling program."

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

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.

Although the assumptions made by the Company in providing forward looking information or making forward looking statements are considered reasonable by management at the time, there can be no assurance that such assumptions will prove to be accurate

Forward-looking information and statements also involve known and unknown risks and uncertainties and other factors, which may cause actual results, performances and achievements of NexGen to differ materially from any projections of results, performances and achievements of NexGen expressed or implied by such forward-looking information or statements, including, among others, negative operating cash flow and dependence on third party financing, uncertainty of the availability of additional financing, the risk that pending assay results will not confirm previously announced preliminary results, imprecision of mineral resource estimates, the appeal of alternate sources of energy and sustained low uranium prices, aboriginal title and consultation issues, exploration risks, reliance upon key management and other personnel, deficiencies in the Company's title to its properties, uninsurable risks, failure to manage conflicts of interest, failure to obtain or maintain required permits and licenses, changes in laws, regulations and policy, competition for resources and financing, and other factors discussed or referred to in the Company's Annual Information Form dated March 31, 2017 under "Risk Factors".

Although the Company has attempted to identify important factors that could cause actual results to differ materially from those contained in the forward-looking information or implied by forward-looking information, there may be other factors that cause results not to be as anticipated, estimated or intended.
