VANCOUVER, June 2, 2014 /CNW/ - NexGen Energy Ltd. (TSX-V: NXE) ("NexGen" or the "Company") is pleased to announce it has received its
final assay results from the winter drilling program at Rook 1, and
from the Arrow prospect.
The assay results (highlight zones shown on Figs 1 and 2) confirm the
excellent hand-held scintillometer radiometric and down hole gamma
probing results at Arrow during the winter 2014 program (Fig 3, Table
1), and extend the actual zones of uranium mineralization. All eight
holes contained composite assay intervals exceeding the baseline
parameters, these being a cutoff grade of 0.01 wt% U3O8, a maximum 2 m internal waste dilution, and a minimum 0.25 m thickness.
Higher grade zones were calculated using cutoffs of 1.00 wt% U3O8 and 5.00 wt% U3O8. The composite assays are shown on Table 2.
Andrew Browne, NexGen's Vice-President, Exploration and Development,
commented "The actual uranium assays at Arrow are outstanding in terms
of the location of uranium, the high grade, thickness, and continuity
between holes on sections. Based on these initial assay results and our
current geological interpretation of Arrow's distinctive
characteristics, we are very confident with respect to the potential of
Arrow to host substantial bulk tonnage basement mineralization."
Leigh Curyer, CEO commented, "The Arrow assay results have far exceeded
a realistic expectation of where the program was anticipated to be in
such a short space of time. Arrow is shaping up to be a special uranium
deposit in its own right. The core NexGen technical team of Andrew
Browne, James Sykes and Matthew Schwab are constantly raising the
industry standard in their approach, technical ability and commitment
to uranium discovery in the region. I would like to also take the
opportunity to acknowledge our consultants contribution to Arrow in
Allan McNutt, J Allan McNutt Consulting Inc, and Rod Koch, Koch
Geophysical Consultants. Well done to all."
At Arrow, the host lithologies comprise very steeply-dipping very
competent medium/coarse-grained high-metamorphic grade
quartz-garnet-feldspar-biotite/chlorite gneiss with minor graphitic
intervals. Uranium mineralization is localized within fractured,
sheared, brecciated, and nested veined structurally-disturbed zones,
also steeply dipping but cross-cutting the host rock foliation (Figs 1
and 2). Mineralization is accompanied by minor associated alteration,
primarily being hematization, of generally low intensity except
immediately adjacent to the uranium veins.
Very minor intervals of elevated copper (Cu) and lead (Pb) are located
with some high-grade uranium zones, but potentially deleterious
elements such as arsenic (As), selenium (Se), cadmium (Cd) and mercury
(Hg) generally constitute only background levels. Arrow is essentially
a monomineralic uranium deposit without noticeable deleterious metals
or waste.
All samples were analysed at the Saskatchewan Research Council
Geoanalytical Laboratories (SRC) by ICP-OES/MS for a suite of 99
elements including U3O8. The latter was analysed by partial digestion techniques. Duplicate
samples were also submitted to SRC by NexGen, and information from
those sample results have validated NexGen's QA/QC procedures. Selected
check samples have been taken from all mineralized holes for analysis
by Neutron Activation Analysis (NAA) and/or by Direct Neutron Counting
(DNC) for U, and will be submitted shortly.

Forward-Looking Information
This news release contains "forward-looking information" within the
meaning of applicable Canadian securities laws. Generally, but not
always, forward looking information is identifiable by the use of words
such as "will" and planned" and similar expressions. Forward-looking
information is based on the then current expectations, beliefs,
assumptions, estimates and forecasts about the Company's business and
the industry and markets in which it operates. Such information is not
a guarantee of future performance and undue reliance should not be
placed on forward-looking information. Assumptions and factors
underlying the Company's expectations regarding forward-looking
information contained herein include, among others: that general
business and economic conditions will not change in a material adverse
manner; that financing will be available if and when needed on
reasonable terms; that the Company's current exploration activities can
be achieved and that its other corporate activities will proceed as
expected; that third party contractors, equipment and supplies and
governmental and other approvals required to conduct the Company's
planned exploration activities will be available on reasonable terms
and in a timely manner.
Although the assumptions made by the Company in providing forward
looking information are considered reasonable by management at the time
the forward-looking information is given, there can be no assurance
that such assumptions will prove to be accurate. Forward-looking
information also involves known and unknown risks and uncertainties and
other factors, which may cause actual events or results in future
periods to differ materially from any projections of future events or
results expressed or implied by such forward-looking information,
including, among others: risks related to the availability of financing
on commercially reasonable terms and the expected use of the proceeds;
changes in the market; potential downturns in economic conditions;
industry conditions; actual results of exploration activities being
different than anticipated; changes in exploration programs based upon
results of exploration; future prices of metal; availability of third
party contractors; availability of equipment and supplies; failure of
equipment to operate as anticipated; accidents, effects of weather and
other natural phenomena and other risks associated with the mineral
exploration industry; environmental risks; changes in laws and
regulations; community relations; and delays in obtaining governmental
or other approvals or financing. There can be no assurance that
forward-looking information will prove to be accurate, as actual
results and future events could differ materially from those
anticipated, estimated or intended. NexGen undertakes no obligation to
update or reissue forward-looking information as a result of new
information or events except as required by applicable securities laws.
The reader is cautioned not to place undue reliance on forward-looking
information.
