Colombian Mines Samples 104 Gram Gold at El Dovio, Colombia

VANCOUVER, BRITISH COLUMBIA--(Marketwire - May 11, 2011) -Colombian Mines Corporation ("Colombian Mines" or "the Company") (TSX VENTURE:CMJ) announces recent saw cut channel sampling has returned assays in separate samples exceeding 104 grams per tonne gold (g/T Au), 98 grams per tonne silver (g/T Ag), 14 percent copper (% Cu) and 3 percent zinc (% Zn), from outcropping mineralization in the Sabana Blanca Zone at its El Dovio project in Colombia. The uncapped, length weighted average of all saw cut channel samples is 3.7 g/T Au, 10.8 g/T Ag, 1.4% Cu and 0.3% Zn, within the 50 to 100 meter wide by 600 meter long combined soil and rock geochemical anomaly that defines the Sabana Blanca zone. Sampling has also identified a central high grade zone that averages 15.8 g/T Au, 21.0 g/T Ag, 2.5% Cu and 0.7% Zn over a true width of 5.3 meters. Mineralization remains open to expansion in all directions and at depth. A channel sample location map is available on the Company's website.

Reconnaissance work in the Sabana Blanca area has identified outcropping alteration and mineralization with similar characteristics that continue to confirm the overall continuity of mineralization between the two sample transects previously announced by the Company (November 17, 2010). Table 1 presents some of the more significant new mineralized zones, with a more detailed discussion of the results below.

Discussion of Results

This recent channel sampling confirms previous sample results and significantly expands the interpreted width of known mineralization from 24 to over 30 meters. Strongly mineralized samples at the ends of most sample lines indicate excellent potential to expand the length and width of mineralization.

Sample Transect 1- sampled 41 linear meters of mineralization with an estimated true width of 30 meters averaging 2.6 g/T Au, 9.7 g/T Ag, 1.6% Cu, and 0.24% Zn. Within this 30 meter interval, a higher grade zone with a 4 meter true width that averaged 7.9 g/T Au, 21.4 g/T Ag, 3.5% Cu and 0.4% Zn, corresponded well with the central high grade core discussed below. The limits of mineralization have not yet been defined in Transect 1, which ends in highly anomalous mineralization both to the north and south.

Sample Transect 2- located approximately 180 meters northeast of Transect 1, sampled 45 linear meters of mineralized outcrop in Sabana Blanca Creek with an estimated true width of approximately 35 meters grading 5.6 g/T Au, 6.75 g/T Ag, 0.5% Cu, and 0.4% Zn, that included 7 meters grading 27.4 g/T Au, 8.1 g/T Ag, 0.2% Cu and 0.6% Zn. Contained within this 7 meter zone is 3 meters grading 58.6 g/T Au, 14.6 g/T Ag, 0.26% Cu, and 0.81% Zn, including one meter assaying 104.5 g/T Au, 21.7 g/T Ag, 0.06% Cu and 1.15% Zn. Transect 2 does not define the limits of mineralization and ends both to the north and south in highly anomalous material.

Sample Transect 3- located approximately 30 meters westerly from Transect 2, sampled 13 meters with an interpreted 8 meter true width averaging 1.9 g/T Au, 26.5 g/T Ag, 0.5% Cu, and 0.05% Zn. The sample interval ends to the north in mineralization assaying 1.5 g/T Au and to the southwest in material assaying 5.2 g/T Au.

Sample Transect 4- located approximately 75 meters southwest of Transect 2 and 57 meters southerly from Transect 3, channel results here produced 9 linear meters of mineralization with an estimated true width of 6 meters averaging 1.2 g/T Au, 10.2 g/T Ag, 0.9% Cu, and 0.03% Zn. Both ends of the sample line end in anomalous gold.

Sample Transect 5- located mid-way between Transect 1 and 2, approximately 94 meters southwest of Transect 2, sampled 24 linear meters of mineralized outcrop with an estimated true width of 13 meters grading 1.4 g/T Au, 2.2 g/T Ag, 0.3% Cu and 0.06% Zn. Contained within the 24 meters is a 4 meter zone of higher grade mineralization averaging 7.8 g/T Au, 9.9 g/T Ag, 0.4% Cu, and 0.04% Zn.

Sample Transect 6- located approximately 20 meters west of Transect 1, sampled 6 meters true width of highly mineralized material that averaged 13.0 g/T Au, 43.4 g/T Ag, 5.9% Cu, and 1.4% Zn.

High Grade Zone Indicated: The high grade intervals found in Sample Transects 1, 2, 5, 6 and the southernmost end in 3, are thought to define a continuous high grade zone estimated to average 15.8 g/T Au, 21.0 g/T Ag, 2.5% Cu and 0.7% Zn over an estimated 5.3 meter true width within the larger Sabana Blanca Zone. Although partially observed in previous sampling in two exposures, this high grade trend is now much better defined in this most recent saw cut channel program with better quality samples taken from five transect areas. The present results show this to be an emerging central high grade core within a much broader well mineralized zone.

Sampling methods used to acquire diamond saw cut channel samples, such as those reported here, conform to industry best practices. Data from this sampling method can have confidence levels equivalent to that obtained from diamond drill core results.

The Company is currently expanding the geochemical grid to cover additional areas of high mineral potential. It has successfully rehabilitated the historic Mina Sabana Blanca tunnel and our crews are now in the process of surveying, mapping and diamond saw channel sampling this important exposure of mineralization.

Upcoming Events

Colombian Mines will be attending Money Talks, Resource Investment Conference in Edmonton May 14, and the Cambridge, Vancouver Investment Conference June 5th and 6th, 2011. Please come by and visit with us at booth number 14 in Edmonton and booth number 1009 in Vancouver.

Sample Collection - Quality Control – Quality Assurance

The Company's samples are collected in accordance with accepted industry best practices. All channel samples were diamond saw cut to a nominal width of three centimeters, two centimeters deep and one meter in length. After cutting, each sample is collected by hammer and chisel, sealed into individual sample bags, and delivered to the ALS-Chemex sample preparation facility in Medellin, Colombia. Sample Pulps are delivered by Chemex to their analytical laboratory in Lima, Peru. The Company maintains rigid QC-QA through insertion of a series of blank, duplicate and certified standards at a rate of 1:30 or higher.
