COLOMBIA GOLDFIELDS UPDATES MARMATO RESOURCE DEFINITION DRILL PROGRAM

TORONTO, Ontario, (September 2, 2008): Colombia Goldfields Ltd. (or the “Company”) (TSX: GOL / OTCBB: CGDF) today provided an update on its ongoing 60,000 meter resource definition drill program in the Zona Alta (Upper Zone) at the Marmato Mountain gold project in Colombia. Highlights include:

• New results based on 8,396 meters in 34 diamond drill holes;

• Intercepts included 20.0 m at 0.91 g/t Au, 22.0 m at 1.60 g/t Au, 100.0 m at 0.47 g/t Au, 21.0 m at 0.99 g/t Au, 44.0 m at 1.48 g/t Au, 35.8 m at 1.36 g/t Au, 16.0 m at 4.95 g/t Au, 76.0 m at 1.03 g/t Au, and 31.5 m at 0.84 g/t Au;

• Drilling to date is 40,735 meters in 188 holes, including 10 in progress;

• 10 diamond drill rigs operating;

• Underground sample results from 399.5 m of channel samples in cross-cuts and 119 m of individual samples; intercepts included 112 m at 0.56 g/t Au and 10 m at 2.60 g/t Au.

To date, 40,735 meters of drilling has been completed in 188 diamond drill holes, including 10 holes in progress. In May 2008 the Company announced an initial NI 43-101 compliant inferred resource estimate of 2.6 million ounces of gold (at a cut-off grade of 0.3 g/t Au) for the Zona Alta at Marmato (see press release of May 12, 2008). The estimate was based on the first 12,186 meters (68 holes) of diamond drilling, 1,165 meters of cross-cut samples (115 cross-cuts) and 504 meters of individual underground samples.

Results from 34 new holes (8,396 meters) have been received since the last drill results were published (see press release of June 2, 2008) and are listed in Table 1. Results have now been received for a total of 140 holes representing 27,910 meters. The drill hole locations are shown on the accompanying plan.

The underground sampling program has been completed in all accessible mines in the Zona Alta. Some mines remain to be sampled once title is transferred to the company. New results have been received for 399.5 m of channel samples from 22 cross-cuts in 7 mines, and are listed in Table 2. In addition, results have been received for 90 individual samples of mine faces and backs totalling 114.7 m in 6 mines and are listed in Table 3. In total, 65 mines have been sampled for a total of 1,912.9 m in 1,387 samples. This comprises 1,257.5 m of channel sampling in 127 cross-cuts (662 samples), and 725 individual samples totalling 655.4 m. The average grade of all individual samples is 2.68 g/t Au and 15.5 g/t Ag over 0.90 m.

Dr Stewart D. Redwood, Vice President of Exploration of the Company, is the qualified person as defined by NI 43-101 and has prepared or supervised the preparation of all scientific and technical information contained in this press release. He is a Fellow of the Institute of Materials, Minerals and Mining (FIMMM) of the UK, a foreign professional association and designation recognized by the Canadian regulatory authorities. The laboratories used were Inspectorate (ISO 9001:2000 and 9002:2004 certified) in Medellin, Colombia (sample preparation) and Lima, Peru (analysis), and SGS in Medellin (preparation) and Lima (analysis). Gold was assayed by fire assay with AAS finish, and values above 3.0 g/t were repeated by fire assay with gravimetric finish. Silver was assayed by fire assay with AAS finish and by ICP.  Blank, standard and duplicate samples are routinely inserted for quality assurance and quality control.

United States investors are cautioned not to assume that all or any part of mineral resources will ever be converted into mineral reserves. Inferred mineral resources have a great amount of uncertainty as to their existence, and as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or other economic studies. United States investors are cautioned not to assume that all or any part of an inferred mineral resource exists, or is economically or legally mineable.

The drill holes were inclined and the intersection lengths do not represent true widths. Sample widths are normally 2.0 m but can be varied for geological and recovery factors. A cut off grade of 0.10 g/t Au has been used and no more than 6.0 m of internal dilution. No top cutting of grades has been applied. Results are reported above a minimum average grade of 0.30 g/t Au and a minimum width of 5.0 m. Gold grades are by fire assay with a AA or gravimetric finish; silver grades are by ICP analysis or by fire assay with AA finish.  Mean values were used where assay duplicate and core duplicate data exist. Voids from old mine workings have been assigned zero grade.

Channel samples are horizontal and were cut by diamond saw. Sample widths are normally 2.0 m but can be varied for geological and mine factors. All samples were used to calculate the length-weighted averages and no upper or lower cut-off grades were applied. Different channel samples along the same cross-cut are separated by timbered zones or mine openings and are  denoted by suffixes A, B, etc. Results are reported above a minimum average grade of 0.30 g/t Au and a minimum length of 3.0 m. Samples from 14 other cross-cuts gave no intersections above the cut-off grade and length. Gold grades are by fire assay with a AA or gravimetric finish; silver grades are by ICP analysis or by fire assay with AA finish.  Mean values were used where duplicate sample or assay data exist.

Samples are horizontal and were cut by diamond saw. Single samples were taken across the mine faces and at systematic intervals along the backs where accessible. Sample widths are the mine width. All samples were used to calculate the length-weighted averages. In the two right columns grades have been top-cut to 10 g/t Au and 100 g/t Ag. Gold grades are by fire assay with a AA or gravimetric finish; silver grades are by ICP analysis or by fire assay with AA finish.  Mean values were used where duplicate sample or assay data exist.
