By Cecilia Jamasmie World’s No.1 miner BHP (ASX:BHP) is said to have agreed selling its Cerro Colorado mine, its smallest Chilean copper operation, to EMR Capital Advisors Pty, an Australian private equity firm that invests in natural resources. The Melbourne-based mining giant is supposed to announce the deal as early as Tuesday, according to unanimous sources with knowledge of the matter quoted by Bloomberg. BHP decided to offload its Cerro Colorado mine in May last year, as part of chief executive Andrew Mackenzie’s bid to focus on large assets in commodities such as iron ore, copper and oil.
