VANCOUVER, Oct. 26, 2016 /CNW/ - NexGen Energy Ltd. ("NexGen" or the "Company") (TSX:NXE, OTCQX:NXGEF) is pleased to announce it has received positive preliminary metallurgical results from the Arrow Deposit, which is located its 100% owned, Rook I property, Athabasca Basin, Saskatchewan.
A bench scale metallurgical test program was designed by Grant Feasby, M.Sc., and completed by the Saskatchewan Research Council (SRC) laboratory in Saskatoon to determine the preliminary leaching process, raffinate solution composition, purity of yellow cake product, and tails settling. Tests confirmed that the Arrow Deposit is a "clean" uranium resource, and is amenable to favourable metallurgical processing and waste management practices.
Highlights:
Leigh Curyer, Chief Executive Officer commented: "These positive preliminary results demonstrate another highly favourable technical aspect of Arrow and will be incorporated into our development studies that have been conducted throughout 2016 and will continue to work on in 2017. These studies include environmental, geotechnical, metallurgical and site characterization which will form the basis of, and culminate in, the publication of the maiden pre-feasibility study on the Arrow Deposit scheduled in H2 2017."
The 55 kg composite sample representing the Arrow resource was blended and homogenized from 131 core assay reject samples that yielded a specific gravity of 2.70 g/cm3. The composite head sample returned the results shown in Table 1 below.

From a processing and environmental management perspective these sample analyses indicate that the Arrow Deposit is suitable for conventional acid leaching, solvent extraction and uranium production as ammonium diuranate (yellowcake) or uranyl peroxide (UO4 2H2O). The overall metallurgical test program confirms that a high purity uranium product can be produced, which meets all of the specifications from ASTM C967-13 "Standard Specifications for Uranium Ore Concentrate". All of the sampling, analytical and test work conducted during this program has been reviewed and approved by Grant Feasby, M.Sc.

"Forward-looking information" includes, but is not limited to, statements with respect to the activities, events or developments that the Company expects or anticipates will or may occur in the future, including, without limitation, the proposed use of proceeds and planned exploration activities. Generally, but not always, forward-looking information and statements can be identified by the use of words such as "plans", "expects", "is expected", "budget", "scheduled", "estimates", "forecasts", "intends", "anticipates", or "believes" or the negative connotation thereof or variations of such words and phrases or state that certain actions, events or results "may", "could", "would", "might" or "will be taken", "occur" or "be achieved" or the negative connation thereof.
Such forward-looking information and statements are based on numerous assumptions, including among others, that the results of planned exploration activities are as anticipated, the price of uranium, the anticipated cost of planned exploration activities, that general business and economic conditions will not change in a material adverse manner, that financing will be available if and when needed and on reasonable terms, and that third party contractors, equipment and supplies and governmental and other approvals required to conduct the Company's planned exploration activities will be available on reasonable terms and in a timely manner. Although the assumptions made by the Company in providing forward-looking information or making forward-looking statements are considered reasonable by management at the time, there can be no assurance that such assumptions will prove to be accurate.
