Columbus Gold Receives Phase I Drill Results From Overland Pass

Vancouver, British Columbia, Canada. May 2, 2007. Columbus Gold Corporation (CGT: TSX-V) ("Columbus Gold" or the "Company") is pleased to announce Phase I drill results from its Overland Pass Project, situated on the southern extension of the Carlin Trend, approximately 89 kilometres (55 miles) south of Elko, Nevada. Pursuant to an option agreement, Sniper Resources Ltd. ("Sniper"), a privately-held Vancouver based gold exploration company, is earning an initial 51% interest in Overland Pass by making annual exploration expenditures.

The reverse-circulation Phase I program which was operated by Sniper totaled 2,222 metres (m), (7,290 feet) and was comprised of 13 wide-spread, vertical and angle holes designed to evaluate previously untested parts of the property. Anomalous values of gold were present in most of the holes, with the best-mineralized holes being OP-6 and OP-10. OP-6 encountered 6.1 m (20 feet) of 0.38 grams per tonne (g/t) Au (0.011 oz/ton) at depths of between 45.7 and 51.8 m (150 to 170 feet), within a 15.2 m (50 foot) zone averaging 0.27 g/t Au (0.008 oz/ton). Hole OP-10 was drilled from the same collar, but at a 30 degree difference in azimuth, and encountered 3.05 m (10 feet) at 1.37 g/t Au (0.040 oz/ton) at a depth of between 62.5 and 65.5 m (205 -- 215 feet), within a 16.8 m (55 foot) zone that averaged 0.51 g/t Au (0.015 oz/ton). Oxidation was extensive, suggesting favorable metallurgical characteristics. This mineralized zone appears to have been truncated by a faulted contact which suggests the zone may be thicker than drilled.

Trace element geochemistry from selected samples was performed by BSI-Inspectorate in Sparks Nevada and suggests a Carlin-type system, with anomalous As, Ba, and Sb, and generally low Ag and base metals. Bi was anomalous in places suggesting a possible distal link to intrusive rocks of the Bald Mountain stock, which host some of the ore at the Top Zone Pit at Barrick Gold's nearby Bald Mountain Mine, as a metals/heat source.

Previous grab samples from surface at Overland Pass returned assays up to 15 g/t Au. The stratigraphy includes important host rocks in the region including the Pilot Shale, Joanna Limestone and the Chainman Shale. The geological setting at Overland Pass is similar to that of the Alligator Ridge Mine located approximately 24 km (15 miles) to the south and which produced nearly one million ounces of gold, as well as to several other nearby gold deposits being explored by Barrick Gold.

As a result of the encouraging results from Phase I, a Phase II drilling program is currently being permitted and is planned for the summer of 2007.

Five-foot sample intervals were submitted for initial Au assays to ALS Chemex in Elko and duplicate samples were collected from all intervals. Check assaying and geochemical analysis of selected samples was conducted by BSI-Inspectorate, in Sparks Nevada.
