Columbus Gold Drilling Expands Dimensions Of Gold Deposit At
Golden Mile
======================================================================

Vancouver, British Columbia, Canada. February 23, 2007. Columbus Gold
Corporation (CGT: TSX-V) ("Columbus Gold" or the "Company") is pleased
to announce the results of its 1,976 metres (6,483 feet) Phase II
reverse circulation drilling program at its Golden Mile Project
completed in late 2006. Gold mineralization at Golden Mile occurs in
the Central Zone, which was the focus of historic drilling and the
target of the Company's 15 hole, Phase I drilling (see news release
dated August 14, 2006), and also in the West Zone which had historic
drilling with shallow, low-grade gold intercepts. The West Zone, which
has not been drilled by Columbus Gold to date, is located approximately
230 m (750 feet) west of the south end of the Central Zone.

The Phase II drill program was designed to test the possible extension
of the mineralization found in the Central Zone in Phase I drilling
(hole MI-6, 7.6 m of 4.2 g/t gold, and hole MI-12, 9.1 m of 13.8 g/t
gold) to the north, under post-ore volcanic cover. The second goal of
the program was to explore the undrilled area between the Central Zone
and the West Zone.

The gold mineralization in the Central Zone is structurally controlled,
both in an intrusive rock and in the wall rocks (skarn) of the
intrusive, with erratic grades and widths. The intercepts in the recent
drilling to the north of the Central Zone are all hosted in intrusive
rock, and much greater thicknesses of continuous low-grade material
were encountered (best holes MI-22 with 57.9 m (190 feet) of 0.65 g/t
(0.019 opt) Au, and MI-16 with 80.8 m (265 feet) of 0.39 g/t (0.0114
opt) Au. This mineralization, although low-grade, presents a very large
volume target, and remains open north, west, east, and down-dip of the
current drilling.

Drill holes MI-25 and MI-26 were angle holes drilled between the West
Zone mineralization and the southern portion of the Central Zone. The
holes are the first that indicate that the West Zone and the Central
Zone likely connect, however further drilling will be required to
confirm that interpretation.

Drill holes MI-27 and MI-28 were exploratory holes drilled well west of
the West Zone, and seem to confirm the western limit of gold
mineralization has been reached.

Schedule A presents the Phase II drill data table in full; holes MI-16
through MI-24 were drilled to extend the Central Zone.

The Golden Mile Property consists of 24 mineral claims, covering
approximately 154 hectares (380 acres), located along the Walker Lane
Gold Trend in Southwest Nevada. Subject to net smelter return
royalties, Columbus Gold controls a 100% interest in the Property. The
geologic setting at Golden Mile is similar to the productive Fortitude
(Newmont) and McCoy (Kinross) mines on the Battle Mountain Trend.
Golden Mile produced approximately ten thousand tonnes grading 12 g/t
gold in the 1930's. Geophysical surveys and limited drilling carried
out in the 1970's and 1980's defined skarn, breccia and disseminated
gold

mineralization and included a drill intercept of 16 g/t gold along 29.5
m, which included 47 g/t gold over 9.1 m.

QUALITY ASSURANCE/QUALITY CONTROL

Gold assays were determined by fire assay with an AA finish at American
Assay Laboratories in Sparks, Nevada. American performed internal check
assaying on about 7% of the samples. In addition, check analyses are in
progress on a second split on a further 10% of the samples. The second
split was collected at the drill rig at the same time as the first, and
retained for check assaying. Essentially all samples grading more than
1 gram per tonne gold will be checked in this manner, and some
replicate assaying of the second split likely will also be necessary.
The replicate analyses from the first round of drilling in earlier 2006
indicated variations in grade, most likely due to coarse gold
particles, particularly in some of the samples grading 4 grams/tonne Au
or more.

The check sampling program is still in progress. In addition to
internal checking done at American Assay Laboratories, fifty-five
additional check samples have been received so far from the recent
drilling, and these consist of triplicate fire assays (two assay ton)
done on separate splits of cuttings taken at the drill rig. The check
samples range from 49% lower to 67% higher than the original splits,
continuing the pattern seen in earlier drilling which is likely
produced by coarse gold in some samples. Further check sampling is in
progress, and it is clear that the Golden Mile Project will require
core drilling to better interpret the grade of the gold deposits.
