The Globe and Mail reports in its Thursday edition that until very recently, copper player Teck was considered so crucial to Canada's future in a greener global economy that Ottawa bear-hugged the company when it was under attack from Glencore in 2023. The Globe's Tim Kiladze writes that to protect companies such as Teck from takeover suitors, the feds changed the rules for foreign takeovers, telling the world that acquisitions of Canadian mining companies that engage in significant critical minerals operations would only be approved "in the most exceptional of circumstances." That rule change was only in July, 2024. Now Teck is testing the limits of its own protection, and it is not fully clear why. "The industrial logic of an Anglo-Teck combination is compelling due to the material operational synergies available in Chile," Scotia analyst Orest Wowkodaw said in a note. "However, the timing of this deal is hard to understand from a Teck perspective, and the relatively modest implied premium, along with the loss of a Canadian mining champion and the primary [stock] listing, are all disappointments." If Teck's Quebrada Blanca mine in Chile was the motivation, why did Teck not invite a JV partner to help with the costs?
