TORONTO, ONTARIO--(Marketwire - Feb. 18, 2013) -

All amounts are in United States dollars, unless stated otherwise.

Alamos Gold Inc. (TSX:AGI)(NYSE:AGI) ("Alamos" or the "Company") announced today that on February 18, 2013, Alamos and Aurizon Mines Ltd. ("Aurizon") consented to the making of an order by the British Columbia Securities Commission to cease trade any securities issued, or to be issued, in connection with Aurizon's shareholder rights plan (the "Rights Plan"), effective at 5:00 p.m. (Vancouver time) on March 4, 2013, unless Aurizon waives the Rights Plan before such time.

Alamos has agreed to extend the expiry time of its offer (the "Offer") to acquire all of the issued and outstanding common shares ("Aurizon Shares") of Aurizon to 5:00 p.m. (local time) on March 5, 2013, unless further extended or withdrawn. The Offer was scheduled to expire at 5:00 p.m. (Toronto time) on February 19, 2013. The Company will file a Notice of Extension and Variation (the "Notice") with securities regulatory authorities in Canada and the United States and will mail copies of the Notice to all Aurizon shareholders. All other terms and conditions of the Offer remain unchanged.

The parties' agreement with respect to the Rights Plan means that Aurizon shareholders will be free to tender to Alamos' extended Offer without concern about triggering Aurizon's poison pill.

Under the terms of the Offer, Alamos proposes to acquire all of the issued and outstanding Aurizon Shares for consideration of, at the election of each Aurizon shareholder, either (i) 0.2801 common shares of the Company ("Alamos Shares"), or (ii) C$4.65 in cash, in each case, subject to pro-ration based on a maximum cash consideration of C$305,000,000 and a maximum number of Alamos Shares issued of 23,500,000.

How to Tender

Aurizon shareholders are encouraged to continue tendering their shares by completing the Letter of Transmittal included in the documents mailed by Alamos. Kingsdale is available to assist and can be reached at 1-866-851-3214 (North American Toll Free Number) or 416-867-2272 (outside North America). For shareholders whose certificates are not immediately available or who cannot deliver the certificates and all other required documents to Kingsdale prior to the expiry time, they may accept the Offer by properly completing and duly executing a Notice of Guaranteed Delivery and returning it to Kingsdale as specified in the Notice of Guaranteed Delivery. If Aurizon Shares are held by a broker or other financial intermediary, Aurizon shareholders should contact such intermediary and instruct it to tender their Aurizon Shares.

The Offer is now open for acceptance until 5:00pm (local time) on March 5, 2013, unless extended or withdrawn. The Offer is subject to certain conditions, including, among other things, minimum acceptance of the Offer by Aurizon shareholders holding, together with the Aurizon Shares held by Alamos and its affiliates, at least 66 ²/₃ percent of the outstanding Aurizon Shares calculated on a fully-diluted basis.
