Over the course of three decades of operation, we have worked to make mining and sustainable development compatible concepts and realities. This is our history.
1975. The Colombian government invited 17 firms to participate in the bid for mining the 32,000 hectares that currently make up the Cerrejón North Zone. Only five of these companies participated and only three met the requirements: Intercor, an Exxon subsidiary, was chosen.
1976. Carbones de Colombia S.A. (Carbocol) and Intercor, after an international competitive bid, signed a 33-year partnership contract in the month of December for the development of the coal reserves of the Cerrejón North Zone. This contract considers three stages: exploration (1977-1980), construction (1981-1986), and production (1986-2009). An agreement was signed with the Colombian government in January of 1999 to extend the last stage for another 25 years, until 2034.
1977. During the exploration period, 202 studies were carried out.
