Colombia Goldfields Ltd. Reports on Marmato Diamond Drilling
TORONTO, ON, FEBRUARY 28, 2008: Colombia Goldfields Ltd. (the “Company”) (TSX: GOL / OTCBB: CGDF) results of 45 diamond drill holes on the Zona Alta at the Marmato Mountain gold project in Colombia.
Some of the highlights of the current program include: 72.0 meters of 1.62 g/t Au (MT-1002), 65.0 meters of 1.86 g/t Au (MT-1003), 23.45 meters at 1.37 g/t Au (MT-1007), 42.7 meters of 0.83 g/t Au (MT-1008), 32.0 meters of 1.13 g/t Au (MT-1021), 63.85 meters of 0.58 g/t Au (MT-1023), 34.0 meters of 0.81 g/t Au (MT-1026), 42.8 meters of 0.83 g/t Au (MT-1037), 37.7 meters of 1.64 g/t Au (MT-1037), 36.75 meters of 1.13 g/t Au (MT-1041), 36.0 meters of 2.37 g/t Au (MT-1043), 12.90 meters at 9.52 g/t Au (MT-1050), 34.85 meters of 0.84 g/t Au (MT-1052), and 10.0 meters at 11.94 g/t Au (MT-1057).
“Almost all the drill holes at Marmato returned significant gold intersections, longer than five meters,” said Colombia Goldfield’s Vice Chairman and CEO Randy Martin. “Together with the results of channel sampling in underground mines, the results confirm the types of grades and widths reported in the historical drilling and resource estimation reported in our press release of November 14, 2006. A resource calculation based on these results is expected to be completed in March, and ultimately we expect to combine the Zona Alta calculation with Zona Baja (Lower Zone), an asset for which we have a definitive agreement to acquire.”
To February 24, 2008, 15,886 meters of drilling has been completed in 86 diamond drill holes with five more underway. Results from 45 holes (8,829.72 meters) have been received to date and are listed in Table 1. The drill hole locations are shown on the accompanying plan. A resource calculation, which will include the results of approximately 11,000 meters of drilling and approximately 1,700 meters of underground channel sampling, is currently being conducted by Micon International Limited (“Micon”) and is expected to be completed in March 2008. This will be followed by a scoping study which is also being carried out by Micon and is expected to be released during the second quarter of 2008.
A larger drill program for a cumulative total of 60,000 meters is underway to upgrade and define additional resources with completion planned in the fourth quarter of 2008. The number of diamond drill rigs at Marmato will be increased from the current five to ten in the coming months. In addition, a 10,000 meter drill program, planned on the five new gold targets in the Caramanta exploration project surrounding Marmato Mountain, will start in the second quarter of 2008.

The Company samples were prepared by Inspectorate (ISO 9001:2000 and 9002:2004 certified) at sample preparation facilities in Medellin, Colombia, and Reno, Nevada and assayed for gold by fire assay with gravimetric finish or AAS finish and analyzed for silver and a suite of multi-elements by ICP at their laboratories in Reno, Nevada, and Lima, Peru. Additional laboratories used were SGS in Medellin, Colombia (preparation) and Lima, Peru (analysis), and ALS Chemex in Reno, Nevada (analysis) using the same analytical methods. Blank, standard and duplicat e samples are routinely inserted for quality assurance and quality control.

The drill holes were inclined and the intersection lengths do not represent true widths. A cut off grade of 0.10 g/t Au has been used. 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. Mean values were used where duplicate data exist. In the case of core duplicates the average value has been used. Previously released holes MT-1001, MT-1002 and MT-1003 have been reassayed and restated to a lower cut off grade.
