Operator Receives Provincial Approval to Conduct Feasibility Field Test at Wheeler River

Saskatoon, Saskatchewan – TheNewswire – July 15, 2022 – UEX Corporation (TSX:UEX), (OTC:UEXCF) (“UEX” or the “Company”) is pleased to announce that Denison Mines Corp. (“Denison”), the operator of the Wheeler River Joint Venture (“WRJV”), has reported that it has received approval from the Province of Saskatchewan to prepare, construct, and operate the facilities required to carry out the In-Situ Recovery (“ISR”) Feasibility Field Test (“FFT”) planned for the Phoenix Deposit. The WRJV is 10% owned by JCU (Canada) Exploration Company, Limited (“JCU”) and 90% by Denison. JCU is 50% owned by UEX.

The Saskatchewan Minister of Environment approval authorizes the operation of “pollutant control facilities” typical for mining operations and allows for the management of material recovered from mineral extraction through to waste water treatment, discharge, and storage. This approval authorizes the construction of the FFT facilities, which is expected to commence shortly.

The Canadian Nuclear Safety Commission has determined that a Nuclear Substance License will be required to possess and store a nuclear substance resulting from the operation of the FFT (in this case mineralized solution containing uranium). Denison reports that the process to obtain this license is well advanced, and it is expected to be received before the site preparation and commissioning activities are completed.

Further details and results of the Phoenix FFT approval can be found in Denison’s news release dated July 12, 2022 and filed on Denison’s profile on SEDAR.com
