Northeast along Strike from the Arrow Zone

VANCOUVER, Jan. 20, 2015 /CNW/ - NexGen Energy Ltd. (NXE:TSXV) ("NexGen" or the "Company") is pleased to report on initial results from a radon in lake water survey by RadonEx Exploration Management Ltd. at our 100% owned Rook I property, located in the southwest part of Saskatchewan's Athabasca Basin.



Highlights include:


A multi-point 480 m long by 20 to 150 m wide radon in lake water anomaly has been discovered 400 m northeast along strike from the Arrow zone (see Figure 1);


Radon values up to 10.4 pCi/L are in the same range as the radon values that lead to the discovery of the R390E R780E zones at the adjacent PLS property by the Alpha-Fission joint venture (see news release February 19th, 2013);


This radon anomaly discovery has developed a high priority drill target that will be drilled during the ongoing winter 2015 program;


Location of this clustered radon anomaly is optimally situated where the southeast dipping VTEM conductor is projected to reach the unconformity.


Garrett Ainsworth, Vice President, Exploration & Development commented, "The results of this radon in lake water survey adds another layer of data that further enhances the prospectivity of this target area situated 400 m northeast along strike from the Arrow zone, which has now become a high priority to drill during this winter program. The results from all geophysical and geochemical surveys conducted to date in this particular area of Rook I, all continue to support that the 4 km strike length northeast of Arrow within the Patterson Conductor Corridor has excellent potential to discover additional zones of basement mineralization, as well as Athabasca sandstone hosted and unconformity-style mineralization."



Leigh Curyer, Chief Executive Officer commented, "Arrow is currently developing rapidly into a significant resource in its own right. To identify an additional target zone meeting all geophysical and geochemical parameters to justify drilling only 1km north east of Arrow is incredibly exciting for the Company."



A detailed airborne VTEM Plus and magnetometer survey on 100 m line spacing was flown over the northeast strike extension from the Arrow zone. The Arrow zone is associated with a north-northwest cross-cutting structure, which is interpreted to repeat at least three times within a 4 km section northeast along strike from Arrow (see Figure 2). Favourable magnetic and gravity settings are also associated with these recently located VTEM conductors. As a follow-up to these encouraging VTEM results, a radon in lake water survey is in progress with a focus on these prospective cross-cutting structures.



RadonEx Exploration Management of St. Lazare, Quebec has been contracted to conduct an approximate 1,700 station radon in lake water survey over VTEM conductors beneath Patterson and Beet Lakes. Detailed radon sampling has just begun along an approximate 4 km strike length to the northeast of the Arrow zone with 309 samples recovered thus far. In General, sample location spacing is 20 m apart along lines that are 50 to 100 m apart. Radon results will be released as they become available, and are interpreted.
