Colombian Mines Provides Update on Proposed Private and Placement and Joint Venture

VANCOUVER, 05/29/12 - Colombian Mines Corporation (TSX VENTURE: CMJ) (FRANKFURT: X6C) ("Colombian Mines" or "the Company") today provided an update on its previously announced agreement with Teck Resources Limited ("Teck") for a proposed non-brokered private placement (the "Private Placement") and subsequent entry into an option agreement (the "Option Agreement") for the acquisition by Teck of up to a 70% joint venture interest in the Yarumalito project.

The Private Placement was previously intended to close in two tranches with each closing conditional upon the completion of certain mining filings and registrations required to be made in Colombia. Teck acknowledges that the first condition precedent has been met and that sufficient progress has been made to waive the second condition such that the Private Placement will be completed in one tranche for a total of 2,850,000 units of the Company at a price of $0.53 per unit for gross proceeds of Cdn$1,510,500. All other terms of the Private Placement remain the same.

Both the Private Placement and Option Agreement remain subject to regulatory approval.
