Vancouver, B.C., September 12, 2013 - Columbus Copper Corporation (CCU: TSX-V) (formerly Empire Mining Corporation) ("Columbus Copper") is pleased to announce that it has amended its "fixed" stock option plan (the "Old Plan") to change it to a 10% "rolling" plan (the "New Plan").

Under the Old Plan, Columbus Copper had reserved a fixed number of 8,000,000 common shares for the grant of stock options. Under the New Plan, Columbus Copper may grant stock options to purchase up to 10% of its issued share capital at the time of an applicable option grant. Based on Columbus Copper's current issued share capital of 93,347,977, it will initially have approximately 9,334,797 stock options available for grant, which number includes the 7,565,000 options that are currently issued and outstanding. The New Plan is subject to TSX Venture Exchange approval, as well as the approval of Columbus Copper's shareholders at the upcoming Annual General and Special Meeting to be held on October 18, 2013; the Old Plan will remain in place until Columbus Copper has obtained the aforementioned approvals. A copy of the New Plan will be available for examination at such meeting.
