High Grade Mineralization In The El Dovio System

VANCOUVER, BC - Colombian Mines Corporation reported that hole D13-02 (hole 2) intersected 12.4 meters of high grade, sulfide rich mineralization assaying 4.02 grams gold per metric tonne (g/T Au), 20.23 grams silver per metric tonne (g/T Ag), 4.17% copper (Cu) and 0.46% Zinc (Zn) from 79.5 to 91.9 meters with a combined gold equivalent (Au_Eq) of 11.51 g/T Au_Eq. This impressive zone of mineralization was intersected in a 30 meter horizontal step out from high grade mineralization intersected in hole D13-01A (hole 1) and occurs within a larger mineralized intercept averaging 3.43 g/T Au, 17.93 g/T Ag, 3.6% Cu and 0.40% Zn over 15.4 meters from 77.5 to 92.9 meters. Contained within these mineralized zones is a high-grade sub-interval averaging 9.36 g/T Au, 30.06 g/T Ag, 5.16% Cu and 0.5% Zn from 89.3 to 91.9 meters. This mineralization corresponds with projections of high grade mineralization found in the Sabana Blanca Adit, previously announced hole D13-01A and mapped surface outcrop confirming both lateral and vertical continuity of high grade mineralization in the El Dovio System.

Gold equivalency calculations are included to more clearly present the approximate value of the polymetallic mineralization at El Dovio. The gold equivalency for silver, copper and zinc are adjusted for the recovery rate of the respective metal. The recovery rates used are actual recoveries achieved on mineralization from the Sabana Blanca adit using conventional froth flotation as reported to the Company by McCllelan Laboratories, a prominent metallurgical laboratory based in Reno, Nevada. Recovery rates are as reported in the Company's press release of April 24, 2012, are 91.1% for silver, 97.8% for copper and 96.8% for zinc. In commenting on the flotation results, Mr. Gene McCllelan, principal of McCllelan Laboratories stated that "in more than 38 years of experience the El Dovio mineralization is some of the most responsive to flotation recovery that I have ever seen." Recoveries may be somewhat higher in actual practice because oxidation products seen in the adit that are known to reduce recovery by flotation methods are not observed in this hole and are not expected to occur widely in the zone of mineralization.
