MINNEAPOLIS (AP) — Swiss commodities giant Glencore moved Monday to take full ownership of PolyMet Mining, a company that’s developing a copper-nickel mine in northeastern Minnesota with one of Canada’s largest miners, Teck Resources.
Glencore already owns 82% of PolyMet Mining and has long been the project’s main financial backer. It offered Monday to pay around $71 million to raise that stake to 100%, which would take St. Paul-headquartered PolyMet private. Glencore’s proposal represents around a 167% premium over PolyMet’s closing stock price on Friday, and shares surged on the news in Monday’s trading.
