NexGen Energy Ltd. (“NexGen” or the “Company”) (TSX:NXE, OTCQX:NXGEF) is pleased to report commencement of an independent maiden Preliminary Economic Assessment (“PEA”) on the Arrow Deposit, and results from the on-going winter 2017 drilling program at our 100% owned, Rook I property, Athabasca Basin, Saskatchewan.
Initiation of Maiden PEA:
Advanced work has commenced on an independent maiden PEA which will incorporate the updated mineral resource estimate released on March 6, 2017 (see News Release dated March 6, 2017). The PEA is scheduled to be completed late Q2/early Q3 2017 and will outline the following key aspects of Arrow:

• Annual production rate
• Operating life
• Mining method
• Capital expenditures
• Operating costs
• Economic returns including: internal rate of return, net present value, payback period and sensitivity analysis.

Roscoe Postle Associates Inc., a leading independent consulting company with substantial experience in the Athabasca Basin, and around the globe will be preparing the PEA.
Drilling Highlights:
Southwest Shallow Dravite A2
Drilling in a previously identified area of strong hydrothermal alteration within the A2 shear located southwest of Arrow, has intersected mineralization including off-scale radioactivity for the first time. This new area of mineralization begins 170 m below surface and is located 275 m up-dip and southwest of the A2 Mineral Resource domains. Highlighted holes include:
Scissor hole AR-17-128 intersected 6.0 m of total composite mineralization including 1.1 m of total composite off-scale radioactivity (>10,000 to 32,000 cps) within a 23.0 m section (195.0 to 218.0 m).
Scissor hole AR-17-125 (50 m down-dip from AR-17-128) intersected 10.5 m of total composite mineralization including 0.15 m of total composite off-scale radioactivity (>10,000 to 12,500 cps) within a 13.0 m section (236.0 to 249.0 m).
