We currently lead the national trade in the purchase of minerals such as silver, copper, zinc, lead and many more, achieving successful marketing at a national level. We have a 5-year track record knowing the mineral concentrate marketing sector in Colombia and managing projects with community, which makes marketing and relationships easier for us. In addition to this we have experience in legal export procedures with the Colombian authorities, being already recognized in the environment. Our profitability lies in the volumes of cargo handled and not in high profit percentages, since we must be support and model for the Colombian producer who, with his efforts, delivers this precious material.
