VANCOUVER, CANADA – GoviEx Uranium Inc. (TSX-V: GXU;OTCQB: GVXXF) (“GoviEx” or“Company”) announces the results of a
review study (“Review ”) performed by Synexus (Pty) Limited (“Synexus ”) to identify and assess opportunities to use membrane separation
technologies to reduce the capital and operating expenses as well as increase efficiency in the recovery of uranium and molybdenum, at the
Company’s fully permitted Madaouela Project in Niger (the “Madaouela Project”). “The potential operating and capital savings highlighted by the Review
, while preliminary in nature, are very encouraging and support our decision to undertake this assessment. This work underlines GoviEx’s strategy to focus on the
optimization of the Madaouela Project,”commented Daniel Major, CEO.
The Review considered five options whereby membrane separation could be potentially utilized in the process plant design as set out in the independent NI 43-101 technical report titled,
“The Updated Integrated Development Plan for the Madaouela Project, Niger” with an effective date of August 11, 2015, and a revision date of August 20, 2015 (the “Technical Report
”), published on SEDAR under the Company’s profile and available on the Company’s website at www.goviex.com.
The five options described by the Review are as follows:
–to concentrate uranium and molybdenum, and recover sulfuric acid from the pregnant leach solution.
–to recover ammonium carbonate, ammonium hydroxide and carry-over molybdenum from the molybdenum solvent extraction
circuit strip solution.
–to recover sulfuric acid and carry-over molybdenum from the molybdenum oxide filter filtrate.
–to concentrate uranium and recover phosphoric acid from the loaded strip solution.
–to recover sodium hydroxide and carry -over uranium from the sodium diuranate precipitation filter filtrate (or from the precip itation thickener overflow).
Synexus’overall approach and methodology for the Review was to use the existing process design information as set out in the Technical Report for the
membrane test data simulation models , which were then used to assess membrane performance for each option.
“I am very pleased with the progress our team has made to date in exploring potential mine design and process optimization opportunities for our Madaouela Project.
If these efficiencies prove to be fruitful at the Madaouela Project , we will explore the possibility of applying them at our other fully permitted project: the Mutanga Project
in Zambia, ” stated Govind Friedland, Executive Chairman.
