TORONTO, ON — November 18, 2013 — Denison Mines Corp.  (“Denison”) announced that, as of 4:00 p.m. (Toronto time) today, approximately 100,541,657 common shares of Rockgate Capital Corp. (“Rockgate”) have been validly deposited to Denison’s offer to acquire all of the outstanding shares of Rockgate (the “Offer”). Denison has taken up and accepted for payment all of such shares, representing approximately 86% of the outstanding shares. Denison will issue Denison common shares in exchange for the deposited shares on or before November 21, 2013.


“We are delighted that our Offer was met with such overwhelming enthusiasm by Rockgate shareholders. We wish to thank them for their tremendous support and to welcome them as new shareholders of Denison,” said Ron Hochstein, Denison’s President and Chief Executive Officer. “We encourage any Rockgate shareholders who have not yet accepted the offer to do so as soon as possible to enable Denison to proceed to compulsory acquisition.”


Denison has extended its Offer until 4:00 p.m. (Toronto time) on November 29, 2013, in order to allow Rockgate shareholders an additional opportunity to tender to the Offer. Denison has determined that this will be the final extension of its Offer. A notice of extension will be mailed to Rockgate shareholders shortly. If Denison is successful in acquiring 90% of the Rockgate common shares, it intends to acquire all the remaining shares by way of a compulsory acquisition. If the compulsory acquisition procedure is not available to Denison, it will pursue a subsequent acquisition transaction by way of amalgamation or other corporate reorganization so as to acquire the Rockgate common shares not deposited to the Offer.


Denison’s takeover bid remains open for acceptance.  Rockgate shareholders requiring assistance in order to accept Denison’s offer may contact Denison’s Information Agent, Laurel Hill Advisory Group toll free at, 1-877-452-7184 (1-416-304-0211 collect outside North America) or by email at
