Columbus Silver Provides Update to Santa Fe Merger

December 15, 2011

Vancouver, BC, Canada; December 15, 2011 - Columbus Gold Corp. (CGT: TSX-V) (“Columbus Gold”) announces that Columbus Silver Corporation (“Columbus Silver”) has provided an update on its proposed merger with Santa Fe Gold Corporation (OTCBB: SFEG) (“Santa Fe”). Under this update, Columbus Silver has reported that it has entered into definitive agreements governing the proposed plan of arrangement under which Santa Fe has conditionally agreed to acquire all of the common shares (the “Shares”) of Columbus Silver for CDN$0.20 per share in cash (the “Acquisition”). Under the definitive Acquisition agreement, the parties have agreed to use commercially reasonable efforts to complete the Acquisition on or before March 31, 2012, and in any event prior to May 31, 2012. For additional details of the Acquisition, please see Columbus Silver’s September 7, 2011 and December 13, 2011 news releases.

The Acquisition remains subject to conditions, including: (a) Santa Fe obtaining financing in a sufficient amount to consummate the Acquisition; (b) Columbus Silver obtaining shareholder approval for the Acquisition; and (c) all necessary court and regulatory approvals of the Acquisition being obtained, including the approval of the TSX Venture Exchange. Santa Fe must notify Columbus Silver by December 31, 2011 that it has completed the required financing or obtained a firm commitment regarding same, otherwise Columbus Silver will have the option to terminate the Acquisition.

Columbus Gold is a significant shareholder of Columbus Silver, presently holding 4,020,000 shares, representing 10.9% of Columbus Silver’s issued and outstanding share capital. In addition to the foregoing, Columbus Gold directly and indirectly holds convertible promissory notes under which Columbus Silver (and its subsidiary, Columbus Silver (U.S.) Corporation) owe principal amount of $845,209 and US$540,465 on or before August 31, 2012 (the “Notes”). The Notes are convertible at Columbus Gold’s election into shares at $0.10 per such share. Were Columbus Gold to convert the entirety of the principal owed under the Notes, combined with its existing shareholding, Columbus Gold would hold approximately 18,038,880 shares based on Dec 12, 2011 exchange rate of $1USD = $1.03CDN, or 35.5% of Columbus Silver’s issued and outstanding share capital, post-conversion. If such amount of shares are purchased by Santa Fe under the Acquisition, Columbus Gold would receive aggregate sale proceeds of $3,607,776 from such sale.
