Globe and Mail: BHP to mine Ekati diamonds a year longer

Canada’s Globe and Mail newspaper reports that BHP Billiton, 80%-owner of the Ekati mine in the Northwest Territories, will make a $400 million investment to expand the mine. The Australian mega-miner says its decision was based on higher diamond prices buoyed by healthy demand. Mining at the Misery deposit would start in late 2015 and last for two years.
