Mining company South32 has filed a request for arbitration at the World Bank over a dispute with Colombia concerning royalty payments from its majority-owned Cerro Matoso ferronickel mine, the company confirmed on Tuesday.
In February the Andean country’s comptroller opened an investigation into alleged unpaid royalties of 619 billion pesos ($152.3 million) from iron and nickel production at Cerro Matoso between 1982 and 2012.
