Smelter benchmark at decade lows after what was supposed to be a year of mined supply growth turned out to be the second consecutive year of zero growth.
Canada's largest diversified miner said that before beginning the copper mine upgrade, it would have to secure a development partner able to invest $2billion for up to 30% to 40% stake in the project.
Teck Resources Ltd said on Tuesday that lead smelting had resumed at its Trail, British Columbia, facility after a seven-day suspension because of wildfires.
