Cerrejon, operator of an open-pit coal mine in northern Colombia that is the world's largest, said it beat its annual target by exporting 32.8 million tons of coal in 2012.

The joint venture, which is owned in equal parts by multinationals BHP Billiton, Anglo American and Xstrata, said its total output also came in above projections at 34.6 million tons.

"A dry climate enabled production that was 4 percent higher than our target (of 33.3 million tons)," the company said in a press release.

With 307 million tons of coal exported from the Cerrejon mine in La Guajira province since 2002, the company is one of the top exporters in Colombia's mining sector.

The company will continue ongoing expansion efforts in 2013 with the goal of boosting production to 40 million tons annually starting in 2015, the press release said.

Cerrejon is an integrated mining and transport complex made up of an open-pit mine that produces more than 34 million tons of thermal coal annually, a 150-kilometer (93-mile) railway and a maritime port capable of receiving ships of up to 180,000 tons dead weight. EFE
