VANCOUVER, BRITISH COLUMBIA--(Marketwired - Feb 10, 2015) - Columbus Gold Corporation (TSX VENTURE:CGT)(CBGDF) ("Columbus Gold") is pleased to announce drill results from an additional 9 holes from its Phase II resource development diamond drilling campaign at its 100% owned Montagne d'Or Gold Deposit, Paul Isnard Project in French Guiana. Assay results have now been released for 98 holes and results are pending for the remaining 28 holes of the program.

Highlights of the 9 holes (195 to 203) from the Upper Felsic Zone ("UFZ") are reported below:

• Results from the 2013-2014 drilling campaign have confirmed good continuity of the principle Upper Felsic Zone ("UFZ") within the west and east-central sections of the zone.
• Holes 198, 199, 201, 202 and 203 were successful in establishing consistent wide mineralized envelopes in the central section of the UFZ, similar to the east-central section of the deposit.
• Holes 195 and 200 tested the west-central section of the UFZ. As in hole 195, the UFZ is split by a post-mineral mafic intrusion intersected from 267 to 292 meters down hole.
• Holes 196 and 197 were short holes that tested the subsidiary Hanging wall Zone ("HWZ") located to the south and stratigraphically above the principle UFZ, and returned no significant values.

A drill plan and complete results are available at the following link. The drill plan highlights drill hole intersections with a metal factor (g/t gold x true width) ≥50:

The 25,570-meter Phase II drilling program was completed in early November and totalled 126 holes. All assay results from the program are now anticipated by late February. A three-dimensional geological model of the deposit is being generated by a two-dimensional sectional interpretation, and will be used as the foundation for the updated resource model.

The objectives of the Phase II resource development drill program at the Montagne d'Or Gold Deposit were to:

• Complete a 50-meter spacing array over a strike extent of 2,300 meters to a vertical depth of 200 meters from surface, focused on mineralization potentially amenable to open pit mining;
• Increase current mineralized tonnage within the deposit;
• Increase confidence in the gold grade-width distribution;
• Convert portions of the Inferred resources to the Indicated and Measured categories in accordance with NI 43-101 standards; and
• Acquire a better distribution of copper assays for added value to the deposit.

The Montagne d'Or Gold Deposit is presently defined over 2,500-meter by 400-meters and to an average depth of 250 meters from surface. The mineralized zones remain open on strike to the west and at depth. Utilizing a cut-off grade of 0.4 g/t gold, the Montagne d'Or Gold Deposit hosts an Inferred resource of 140.1 million tonnes grading 1.0 g/t gold for a total of 4.31 million contained ounces of gold. Please refer to Columbus Gold's news release of June 30, 2014 for more information.

An updated resource estimate, combined with concurrent comprehensive metallurgical tests and a preliminary environmental assessment are on target to support the completion of a Preliminary Economic Assessment ("PEA") on the Montagne d'Or deposit in the spring of 2015.

The work is being funded by Nord Gold N.V. (LSE:NORD LI) as part of a minimum US$30 million exploration and development program pursuant to which they can earn a 50.01% interest in Montagne d'Or and the Paul Isnard mineral claims, by completing a bankable feasibility study no later than March 2017.

Qualified Person, Technical Info and QA/QC

Diamond drill holes were bored with HQ-size core in the upper oxidized saprolitic zone and NQ-size core in fresh rock. The core was placed in heavy PVC plastic core boxes with covers and delivered by the drilling contractor, Pro Forage Guyane, to the camp Citron logging facilities, located 5 km from Montagne d'Or. Columbus Gold personnel are present at the camp at all times during the drilling program.

The core was photographed for reference, logged (geotechnical and geological) and identified sulphide mineralized sections were sawed in half. Sample lengths vary between 0.5 to 1.5 meters. Individual half core samples were placed and sealed in heavy duty cellophane plastic bags and placed by batch of 9 samples in sealed polypropylene bags for air transport to the Cayenne and trucking to Filab Amsud laboratory in Paramaribo, Suriname, an ISO 9001 and ISO / IEC 17025 accredited laboratory. The remaining half core is stored in core racks on site at camp Citron for reference. Samples were assayed for gold by fire-assay method using an atomic absorption finish on a 50-gram pulp split and ICP-MS multi-element analysis, including copper.

A quality assurance and quality control program (QA/QC) was implemented by Columbus Gold and Filab Amsud to insure the accuracy and reproducibility of the analytical method and results. The QA/QC program includes the insertion of gold and copper standards, blanks and field duplicates in each laboratory assay batch and systematic re-assaying of samples returning values above 5 g/t Au by the fire-assay method using a gravimetric finish on a 50-gram pulp split. As well, 10% of random sample pulps are sent to SGS del Peru S.A.C. laboratory for gold and copper check assaying.

The drilling program was conducted under the supervision of Rock Lefrançois, P.Geo. (OGQ), Chief Operating Officer for Columbus Gold and Qualified Person under National Instrument 43-101. Mr. Lefrançois, the Qualified Person, has reviewed this news release and is responsible for the technical information reported herein, including verification of the data disclosed.
