High rainfall since early February in Tete, Mozambique, had created serious challenges to the Linha do Sena railway.
These conditions have impacted on the transportation of coal, with the company estimating a loss of 250,000 tons in metallurgical coal shipments.
The Brazilian coal giant had increased its 2012 production of metallurgical coal by 83.8% to 5.1 million tonnes with success at the Carborough Downs longwall mine in Queensland and Integra open cut and underground mines in New South Wales, Australia, as well as the Tete mine.
