Aluminum Corp of China , known as Chalco, is set to make its first shipment from Boffa’s bauxite mine in Guinea by early-December, an official from parent and state-owned company Chinalco said on Thursday. A Chinalco official said last month at the China Mining conference in Tianjin that the Boffa launch had been delayed until 2020. Operations at the mine are now expected to be underway by early-December and it will eventually produce 12-million tonnes of bauxite a year.
