Cerrejón is an integrated mining and transport complex in La Guajira, a department in the northernmost section of Colombia. It includes a thermal coal open-pit mine that produces 32 million tonnes a year, a railroad that is 150 kilometres long, and a maritime port able to receive ships of up to 180,000 tonnes dead weight. The company employs 10,000 people, of which over 99% are Colombian nationals. It is the largest private exporter and one of the most important tax payers in Colombia.
Cerrejón is known for its social and environmental programs, which have earned it international awards. The Cerrejón Foundations System comprises four foundations. It works closely with the Colombian government and with national and international bodies to promote and accelerate sustainable, fair development for La Guajira and its people.
Cerrejón is independently operated, but belongs in three equal parts to subsidiaries of BHP Billiton, Anglo American, and Xstrata.
