Rio Tinto Group and Anglo American Plc (AAL), which together own about three-quarters of Palabora Mining Co., said they plan to sell their entire holdings in the South African miner as it no longer fits their investment objectives. Palabora’s main asset, a mine that produces copper and magnetite, “is no longer of a sufficient scale” for either Rio or Anglo, and a sale process for their stakes has started, the companies said today. Rio holds about 58 percent of Palabora and London-based Anglo almost 17 percent. Their combined holding is valued at about $700 million based on the closing price of Palabora stock in Johannesburg trading today. Image of copper spools at Palabora mine, courtesy of Rio Tinto
