Montagne d'Or Gold Deposit Drilling Results

VANCOUVER, BC - Columbus Gold Corporation reported drill results from an additional 7 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. 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.

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.

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.

A quality assurance and quality control program (QA/QC) was implemented by Columbus Gold and FilabAmsud 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.
