UEX Responds to Denison's Offer to Acquire JCU Exploration Company, Limited

(TheNewswire)

UEX Corporation (TSX:UEX ) ( OTC:UEXCF) (" UEX " or the " Company ") responds to Denison Mine Corp.'s (" Denison ") news release of May 4, 2021 announcing that it has delivered an offer (the " Denison Offer ") to Overseas Uranium Resources Development Co., Ltd. (" OURD ") to acquire OURD's wholly-owned subsidiary, JCU (Canada) Exploration Company, Limited (" JCU

As announced on April 22, 2021, UEX entered into a binding agreement with OURD to acquire its wholly-owned subsidiary, JCU (the " UEX Agreement ").  OURD cannot deal with or respond to the Denison Offer and is bound to complete the sale of JCU to UEX (the " UEX Transaction ") pursuant to the terms of the UEX Agreement, subject only to the approval of shareholders of OURD at a meeting which is scheduled to be held on June 18, 2021.  The UEX Transaction was approved by the board of directors of OURD who are obligated to recommend its acceptance by OURD shareholders.  As those directors represent shareholders of OURD hold the majority of the shares of OURD, UEX is confident that the shareholders of OURD will approve the UEX Agreement.

UEX considers the public announcement of the Denison Offer as opportunistic and constitutes an interference in the contractual rights existing between UEX and OURD.  The fact that OURD was looking to sell JCU was generally known in the uranium mining space.  UEX has been in discussions with OURD regarding the acquisition of JCU for several months prior to announcing the UEX Agreement.  If Denison were serious about acquiring JCU, it had more than adequate time and opportunity to act.

The UEX Agreement with OURD is binding and enforceable and it is not open to OURD to consider

any competing proposals.
