Colombian Mines Initiates $1,500,000, 12 Month Exploration Program and Updates Colombia Crest Joint Venture

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 12, 2012) - Colombian Mines Corporation ("Colombian Mines" or "the Company") (TSX VENTURE:CMJ)(FRANKFURT:X6C) is pleased to announce that it has initiated a $1.5 million, 12 month work program at Yarumalito. This work program, managed by the Company's Colombian subsidiary, Corporacion Minera de Colombia, is fully funded by a subsidiary of Teck Resources Limited ("Teck").

As required under the terms of the Option Agreement ("Agreement"), Teck has also paid the Company an additional $380,000 in addition to the previously announced $1.5 million private placement, and is an allowed expenditure under the Agreement. The private placement and cash payment are for general and corporate purposes and are unencumbered by the Yarumalito expenditures. Teck, through its Colombian subsidiary, now has an option to earn up to a 70% indirect joint venture interest in the Yarumalito Project by sole funding the next $10 million in exploration including the current program.

The current work program has focused on the Obispo zone and will be expanded to cover the El Guico and newly identified La Suiza zones. Current and planned work over the next 12 months will consist of expanding detailed geological mapping and collecting rock and soil geochemical samples to be followed by drilling favorable zones.

Colombian Mines, through its wholly owned Colombian subsidiary Corporacion Minera de Colombia, will manage all exploration programs at Yarumalito until Teck has fully earned at least its 55% indirect joint venture interest.
