NexGen Energy Ltd.: Corporate Update on Its Planned Summer Exploration Activities at Radio, Rook I and South-West Athabasca Basin Margin Properties

VANCOUVER, BRITISH COLUMBIA--(Marketwired - May 15, 2013) - NexGen Energy Ltd. (TSX VENTURE:NXE) ("the Company" or "NexGen") is pleased to release its corporate update on planned summer exploration activities at Radio, Rook I and South-West Athabasca Basin Margin properties.

Corporate Update

Planned Summer Drilling:

Radio

At Radio, located immediately adjacent to Rio Tinto's Roughrider deposit, ground logistic preparations are currently underway for a 4,400 metre diamond drilling program focused on the target area immediately east of Radio's western boundary that covers the interpreted structural extension that hosts the adjacent Roughrider discovery. Drilling will commence on completion of the breakup.

Rook I

At Rook I, which is immediately adjacent to the North East of the Patterson Lake South (PLS) uranium discoveries, owned 50/50 by Fission Uranium Corporation and Alpha Minerals Inc, the Company has recently completed a ground gravity survey over the iced lakes section of the Rook 1 claim group. The data is currently being processed.

In addition, the Company plans to conduct several lines of ground DC resistivity in the southern section of Rook 1 adjacent to and along strike from the Patterson Lake South (PLS) uranium discoveries in early summer. The location of the proposed survey is shown on Figure 1. This survey will assist the drill hole targeting for a 1,500 metre diamond drilling campaign to commence shortly thereafter.

South-West Athabasca Basin Margin Properties: Rook 1 / R-Seven / Meanwell Lake / Bishop 1 / Bishop 2

An updated geophysical re-interpretation of the entire southern Athabasca Basin margin is being undertaken, focusing on NexGen's 100% owned projects. The Rook1 / R-Seven / Meanwell Lake / Bishop1 / Bishop 2 area is being worked on currently. Several areas of lesser technical data have been identified where new information is required.

Planning is advanced for a detailed low-level radiometric/magnetic/VLF-EM aerial survey to cover NexGen's 100% owned Rook 1, Bishop 1, Bishop 2, and Meanwell Lake properties, see Figure 2 below. This area has only ever been subject to historical widely-spaced government radiometric surveys, which did not detect the PLS uranium boulder field. The survey is planned for late spring / early summer to minimise the masking effect of snow, meltwater, and swamp. The objectives of this survey include detection of any uranium or alteration features at the surface, obtain detailed aeromagnetics for basement geology interpretation, and to improve location of basement conductors using aerial EM.
