Columbus Gold is a leading gold exploration and development company operating in French Guiana and Nevada. In French Guiana, Columbus is developing its 45% owned Montagne d'Or Gold Deposit, which hosts NI-43-101 Proven and Probable Reserves of 2.75 Moz gold (54.11 Mt @ 1.58 g/t). The results of the March 2017 Bankable Feasibility Study demonstrate an open pit mining operation with average annual gold production of 237,000 oz over the first 10 years of mine life at an average grade of 1.73 g/t that results in an average AISC of US$749 per ounce. There is considerable expansion potential on strike and at depth and exploration drilling is currently underway. In Nevada, Columbus Gold is currently advancing its 100% owned Eastside Gold Project, hosting an NI-43-101 gold resource of 654,000 ounces of gold and 3.9 Moz of silver (35.78 mt @ 0.57 g/t gold and 3.5 g/t silver at 0.15 g/t gold cut-off), 32km west of Tonopah. To date, a total of 37,311 meters (122,411 ft) of drilling in 136 holes has been completed, and advanced detailed metallurgical studies are underway. Further drilling at target-5 (identical geology to the original target) is underway. The company also has controlling interest in 12 other gold projects in Nevada, Arizona and New Mexico.
