Ground Gravity Identifies Additional High Priority Drill Targets at Rook I

Vancouver, BC - NexGen Energy Ltd. (TSX-V: NXE) ("NexGen" or the "Company") is pleased to report on initial results from an ongoing ground gravity survey by MWH Geo-Surveys Ltd. at our 100% owned Rook I property, located in the southwest part of Saskatchewan's Athabasca Basin.

Highlights include:

• Six high priority drill targets have been identified at the "Fury Area" based on geophysical data consisting of VTEM, ground gravity, and magnetics (see Figure 1;
• The "Fury Area" is located approximately 13.5 km to the southeast of the Arrow zone in a section of the Rook I property that is thought to have 10 to 20 m of overburden overlying basement rocks;
• All six high priority drill targets have similar geophysical features that led to the discovery of the Arrow zone in February 2014. These features include VTEM conductors with diminishing conductance approaching offsets, flexures, and breaks that are associated with gravity and magnetic lows;
• The potential for shallow high grade uranium mineralization at the Fury Area has warranted drilling of up to 4,500 m during this winter 2015 program.

Garrett Ainsworth, Vice President, Exploration & Development commented, "The target rich nature of the Rook I property is becoming increasingly evident based upon the results of this and other recent geophysical surveys across the property. The attractiveness of the Fury Area is threefold: it has very similar geophysical signatures to the Arrow zone, has projected depths to basement rock at 10 to 20 meters from surface, and is along trend from encouraging drilling to the south. I look forward to one of our three rigs mobilizing to Fury shortly."

A ground gravity survey was initiated in December 2014 on the Fury Area (Figure 1) to refine drill targeting on the Derkson East conductor corridor, which is also 1.2 km north-northeast along strike from shallow radioactive drill intersections within graphitic pyritic pelitic gneiss (favourable host rock) at Fission Uranium Corp's Far East area, PLS property (see Fission Uranium Corp's news releases dated August 11th and September 25th, 2014). NexGen's Fury Area is further enhanced by the occurrence of a large cluster of uraniferous radiometric anomalies located approximately 4 to 5 km down-ice to the southwest (see Fission 3.0 and Brades news release dated October 15th, 2014). High grade uranium boulders discovered at the PLS property by the Alpha-Fission joint venture in June 2011 were initially identified in 1977 by Canadian Occidental as radiometric, radon and uraniferous soil anomalies, that likely originated approximately 5 km up-ice (northeast) or further from a bedrock source that hosts the Triple R Deposit.
