Arrow Scissor Hole AR-16-91c2 Intersects 22.4 m of Off-Scale Radioactivity
Vancouver, BC, June 16, 2016 - NexGen Energy Ltd. ("NexGen" or the "Company") (TSXV:NXE, OTCQX:NXGEF) is pleased to announce further results from our on-going spring drilling program on our 100% owned Rook I Property, Athabasca Basin, Saskatchewan.
Scissor drilling from southeast to northwest at the Arrow Deposit has confirmed and increased the known width of the higher grade A2 sub-zone (the "Sub-Zone"). Hole AR-16-91c2 has intersected 22.4 m of off-scale radioactivity (>10,000 to >61,000 cps) including a 3.0 m interval of minimum-greater-than-61,000 cps. The central part of the radioactive intersection consists of widespread massive to semi-massive pitchblende mineralization and was drilled 38 m up-dip and northeast of hole AR-15-44b.
The A2 High Grade Domain is associated with dense accumulations of massive to semi-massive pitchblende. It is currently outlined by 23 holes. Assay results for 5 holes from the Sub-Zone remain pending and the Company continues to drill with 2 rigs currently running.

A2 Shear:
-
AR-16-91c2 (38 m up-dip and northeast from AR-15-44b) intersected 89.0 m of total composite mineralization including 22.4 m of total composite off-scale radioactivity (>10,000 - >61,000 cps) within a 171.5 m section (425.5 to 597.0 m), featuring 3.0 m of minimum-greater-than-61,000 cps in the Sub-Zone.
Arrow, Activities & Financial
-
The land-based and basement hosted Arrow Deposit currently covers an area of 870 m by 280 m with a vertical extent of mineralization commencing from 100 m to 920 m, and remains open in most directions and at depth.
-
The spring 2016 program comprising 7,500 m of drilling will be transitioning to the summer 2016 program in late-June.
-
The Company has cash on hand of of approximately $100 million.
A drill hole location map, three-dimensional view of the A2 High Grade Domain, and an A2 long section featuring the Sub-Zone are shown in Figures 1 to 3.
Garrett Ainsworth, Vice-President, Exploration and Development, commented: "Scissor drill holes have been utilized to verify the thickness of high grade mineralization in the A2 sub-zone, and to test high grade mineralization in the A1 shear that was initially discovered by hole AR-16-84c1. Scissor hole AR-16-91c2 validates and expands upon the robust and high grade nature of sub-vertical mineralization contained within the A2 sub-zone."
Leigh Curyer, Chief Executive Officer, commented: "Infilling the currently defined area of Arrow mineralization is delivering growth throughout the deposit both in terms of grade and volume. This scissor hole, along with others previously completed, confirm Arrow's stacked sub-vertical nature which has been instrumental in developing Arrow in a time and cost efficient manner."
