NexGen Commences 25,000m Summer Drilling Program at Arrow Zone

VANCOUVER , June 8, 2015 - NexGen Energy Ltd. (NXE:TSXV) ("NexGen" or the "Company") is pleased to announce that drilling is underway at our 100% owned Arrow Zone, Rook I property, located in the southwest part of Saskatchewan's Athabasca Basin.
The summer 2015 drill program will utilize five diamond drill rigs.  Two rigs are currently in operation with all five scheduled to be turning by June 20 ^th.

Drilling focus

• Two drill rigs will focus on testing the extents of high grade uranium mineralization in the A2 and A3 cores as the company drives Arrow towards an initial resource estimate,
• A third rig will test previously undrilled areas of the A1, A2 and A3 shears targeting high grade uranium mineralization akin to that found in AR-15-44b (40.45m of off-scale radioactivity – assays pending),
• The fourth and fifth rigs will test high priority regional geophysical targets on the Rook I property along the Patterson and Derkson Conductor Corridors. (see Figure 1).

Leigh Curyer, NexGen's Chief Executive Officer commented "The commencement of our summer drilling program which is the largest to date at Rook I, represents an exciting time for NexGen and our shareholders. We anticipate this program to culminate in delivering an initial National Instrument 43-101 compliant resource at Arrow. The regional targets along are the culmination of a dedicated review of geophysical and historical data and fits well with our team's focused exploration philosophy".

The exploration target at Arrow consists of high grade uranium mineralization hosted in basement rocks starting at approximately 100 meters below surface.  The Rook I property is prospective both in the immediate area of the Arrow zone, and further along strike (4 km to the NE and 3 km to the SW) from Arrow which is open for potential expansion in all directions.  Rook I straddles the edge of the Athabasca Basin boundary which gives rise to not only basement-hosted mineralization targets, but also to unconformity-style and sandstone-hosted mineralization targets with a plethora of northeasterly striking EM conductors existing within largely untested corridors (Derkson, R-Seven, Morrow, Mirror, Laurie) that show favourable breaks and flexures within coincident gravity and magnetic lows. 

Two of the three rigs working at Arrow will employ directional drilling methods administered by TECH Directional Services Inc. of Millertown, Newfoundland , who will work closely with diamond drilling contractor Aggressive Drilling Ltd. of Saskatoon, Saskatchewan during the summer program.  The implementation of directional drilling at Arrow will allow for precise and systematic testing of the A2 and A3 shears, and is expected to result in significantly increased drilling efficiency in terms of time and total cost.

Arrow is just within the edge of the Athabasca Basin, is entirely on land and can be predominantly drilled all year round.  The EM conductor hosting the Arrow zone continues to both the northeast and southwest, and will be tested along strike in both directions during the summer drill campaign.  Regionally on the Rook I property, the company has developed a number of high priority geophysical targets with similar features to Arrow that include multiple areas on the largely untested Derkson conductor corridor, at the Fury target area and along strike from the Bow discovery to the northeast on land.
