Caldas Gold is a Canadian mining company currently advancing a prefeasibility study for a major expansion and modernization of its underground mining operations at its Marmato Project in the Department of Caldas, Colombia. Located within a historic mining district, the Marmato Project contains mineral resources of 2.0 million ounces of gold in the Measured and Indicated categories and 3.3 million ounces of gold in the Inferred category. The Marmato Project has excellent infrastructure, being located by the Pan American Highway with access to Medellin to the north and Manizales to the south and has access to the national electricity grid which runs near the property. In 2019, the Marmato underground mine produced 25,750 ounces of gold and in 2020, implementation of a mine optimization program is expected to increase gold production to between 32,000 and 37,000 ounces. Caldas Gold expects to complete a prefeasibility study for the underground mine expansion by mid-2020.
