Workers to strike at Colombia's Cerro Matoso nickel mine

Union workers at Colombia's Cerro Matoso mine, one of the world's largest producers of ferronickel, will begin an indefinite strike on June 14 in protest of work and pay conditions, the union president said. A strike at Cerro Matoso, owned by Australia's South32, could impact global nickel prices as production stalls. Miners last year went on strike at the mine for two weeks before reaching agreement on a dispute that had forced previous owner BHP Billiton to declare force majeure.
