Alamos Gold Inc. (“Alamos”) hereby offers (the “Offer”) to purchase, on the terms and subject to the conditions of the Offer, all of the issued and outstanding Common Shares (the “Common Shares”) of Aurizon Mines Ltd. (“Aurizon”), other than any Common Shares owned, directly or indirectly, by Alamos and its affiliates, and including Common Shares that may become issued and outstanding after the date of the Offer but before the expiry time of the Offer upon the exercise, exchange or conversion of options issued under Aurizon’s stock option plan (“Options”) or any other rights to acquire Common Shares. The Offer, which is subject to certain terms and conditions, is set forth in the offer and related take-over bid circular dated January 14, 2013 (the “Offer and Circular”) and the letter of transmittal and the notice of guaranteed delivery accompanying the Offer and Circular (collectively, the “Offer Documents”), copies of which are being filed with the securities regulatory authorities in Canada and with the United States Securities and Exchange Commission. Copies of the Offer Documents will be available at www.sedar.com and www.sec.gov.

Each holder of Common Shares (a “Shareholder”) may elect to receive either the Cash Alternative or the Share Alternative in respect of all of the Shareholder’s Common Shares deposited under the Offer. The total amount of cash available under the Offer is limited to Cdn$305,000,000 and the total number of common shares of Alamos (the “Alamos Shares”) available for issuance under the Offer is limited to 23,500,000 Alamos Shares.

The Offer is open for acceptance until 5:00 p.m. (Toronto time) on Tuesday, February 19, 2013 (the “Expiry Time”), unless the Offer is extended or withdrawn.

The Offer is subject to certain conditions, which are described in the Offer and Circular, in particular (i) there having been validly deposited or tendered under the Offer and not withdrawn at the Expiry Time that number of Common Shares which, together with the Common Shares held by Alamos and its affiliates, represents at least 66 ²/₃% of the Common Shares outstanding (calculated on a fully diluted basis), and (ii) certain regulatory approvals having been obtained and/or waiting periods having expired. These and other conditions of the Offer are fully described in the Offer and Circular. Subject to applicable laws, Alamos reserves the right to withdraw or extend the Offer and not to take up and pay for any Common Shares deposited under the Offer unless each of the conditions of the Offer is satisfied or waived at or prior to the Expiry Time.

The Common Shares are listed for trading on the Toronto Stock Exchange (the “TSX”) under the symbol “ARZ” and on the NYSE MKT under the symbol “AZK”. The Offer represents a premium of approximately 40% and 39% based on the closing price of Cdn$3.33 and US$3.39 for the Common Shares on the TSX and the NYSE MKT on January 9, 2013, respectively, and a premium of approximately 37% based on the volume-weighted average price of the Common Shares on the TSX and the NYSE MKT for the 20 trading days ended January 9, 2013.

Shareholders whose Common Shares are registered in the name of an investment advisor, stockbroker, bank, trust company or other nominee should immediately contact that nominee for assistance if they wish to accept the Offer in order to take the necessary steps to be able to deposit such Common Shares under the Offer. Such nominees are likely to have established tendering cut-off times that are earlier than the Expiry Time.

When that information is provided, the Offer Documents will be mailed to record holders of Common Shares and Options and furnished to brokers, dealers, banks, trust companies and similar persons whose names, or the name of whose nominees, appear on Aurizon’s shareholder and optionholder lists or who are listed as participants in a security position listing for subsequent transmittal to beneficial owners.
