NexGen Commences Maiden Exploration Drilling on Prospective SW1 Property
NexGen Commences Maiden Exploration Drilling on Prospective SW1
Property
Vancouver, BC, August 26, 2019 – NexGen Energy Ltd. (“NexGen” or the “Company”) (TSX: NXE, NYSE MKT:
NXE) is pleased to announce that an exploration drill program consisting of a minimum 4,000 m is scheduled to
begin in early September at our 100% owned, SW1 property (approximately 10 km northwest of Rook I), in the
Athabasca Basin, Saskatchewan.
SW1 Overview
Since the acquisition by NexGen of the SW1 property (the “Property”) in 2012, NexGen has systematically
developed the property through testing with numerous studies and geophysical surveys. The resulting
geophysical signature on the Property, particularly the Gartner Lake Corridor (“GLC”), displays strong similarities
to the Rook I property (Figure 1) which hosts Arrow, Canada’s largest to-be developed uranium deposit currently
in the Environmental Assessment process. Those similar characteristics include a strong conductive signature
with numerous off-sets coincident with discrete gravity lows and steep magnetic gradients (Figure 2, Figure 3).
Analysis of historic drilling has also revealed prospective structure and alteration that coincides with highly-
favourable geophysical properties for potential uranium mineralization.
Geophysical History
The Property is situated on the western limb of a regional fold structure with the Patterson Lake Uranium
Corridor and the Arrow Deposit situated on the eastern limb (Figure 1). Historical drill core from the Property
show that the area contains similar host rocks as the Arrow Deposit. Given this geological affiliation, NexGen
commissioned the same airborne geophysical techniques that led to the discovery of the Arrow Deposit in
February 2014. A VTEM survey defined several discrete and disjointed conductive corridors on the Property,
similar to what was seen at Arrow. Follow-up ZTEM surveys were conducted in conjunction with HeliFalcon
gravity gradiometry surveys over the entire Property. These surveys defined additional corridors and numerous
gravity anomalies, several of which are coincident with the dislocation of the conductors (Figure 4), similar to the
Arrow Deposit (Figure 4). The development of the Property has led to high-confidence targets that are prime for
focused exploration through drilling.
Drill Program
Exploration drilling with a minimum of 4,000 m, utilizing 2 drill rigs, will commence imminently on the Property.
The program is designed to test the highest-priority anomalies, analogous to those at the Arrow Deposit, for
uranium mineralization that has been highlighted by geophysical surveys and the analysis of historic drilling.
Leigh Curyer, Chief Executive Officer, commented: “We look forward to the SW1 maiden drill program
commencing after completing an extensive geophysical analysis of the area over the past 5 years. NexGen’s
portfolio is host to Arrow and an extensive list of high priority targets generated through the team’s extensive
use of multiple geophysical surveys and objective approach to exploration. The SW1 program is being led by a
sub exploration team as results from the 2019 Phase I Arrow drilling programs are analyzed and incorporated
into the Feasibility Study and Environmental Assessment studies.”
Troy Boisjoli, Vice-President, Operations and Project Development, commented: “The 2019 SW1 exploration drill
program is the culmination of extensive detailed work by the NexGen team for the development of the SW1
property – a methodical build of focused work and high-level interpretation that is akin the strategy that led to
the discovery of the Arrow Deposit in February 2014. We are looking forward to the opportunity to drill test
targets with analogous geophysical signatures to Arrow and excited about this next stage of exploration on the
SW1 property.”

The technical information in this news release with respect to the PFS has been reviewed and approved by Paul
O’Hara, P.Eng. of Wood., David Robson, P.Eng., M.B.A., and Jason Cox, P.Eng. of RPA, each of whom is a “qualified
person” under National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI-43-101”).
The Mineral Resource Estimate was completed by Mr. Mark Mathisen, C.P.G., Senior Geologist at RPA and Mr.
David Ross, P.Geo., Director of Resource Estimation and Principal Geologist at RPA. Both are independent
Qualified Persons in accordance with the requirements of National Instrument (NI) 43-101 and they have
approved the disclosure herein. All other technical information in this news release has been approved by Mr.
Troy Boisjoli, Geoscientist Licensee, Vice President – Operations & Project Development for NexGen. Mr. Boisjoli

underlying the information or opinions contained herein by reviewing original data certificates and monitoring
all of the data collection protocols. All other technical information in this news release has been approved by
Mr. James Hatley, a Professional Engineer, Senior Vice-President – Project Development for NexGen. Mr. Hatley

SEC Standards
Estimates of mineralization and other technical information included or referenced in this news release have
been prepared in accordance with NI 43-101. The definitions of proven and probable mineral reserves used in NI
43-101 differ from the definitions in SEC Industry Guide 7. Under SEC Industry Guide 7 standards, a “final” or
“bankable” feasibility study is required to report reserves, the three-year historical average price is used in any
reserve or cash flow analysis to designate reserves and the primary environmental analysis or report must be
filed with the appropriate governmental authority. As a result, the reserves reported by the Company in
accordance with NI 43-101 may not qualify as “reserves” under SEC standards. In addition, the terms “mineral
resource”, “measured mineral resource”, “indicated mineral resource” and “inferred mineral resource” are
defined in and required to be disclosed by NI 43-101; however, these terms are not defined terms under SEC
Industry Guide 7 and normally are not permitted to be used in reports and registration statements filed with the
SEC. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Investors are
cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted
into reserves. “Inferred mineral resources” have a great amount of uncertainty as to their existence, and great
uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred
mineral resource will ever be upgraded to a higher category. Under Canadian securities laws, estimates of
inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases.
Additionally, disclosure of “contained pounds” in a resource is permitted disclosure under Canadian securities
laws; however, the SEC normally only permits issuers to report mineralization that does not constitute “reserves”
by SEC standards as in place tonnage and grade without reference to unit measurements. Accordingly,
information contained or referenced in this news release containing descriptions of the Company’s mineral
deposits may not be comparable to similar information made public by U.S. companies subject to the reporting
and disclosure requirements of United States federal securities laws and the rules and regulations thereunder.
