Teck Extends Life of Canada’s Biggest Copper Mine Until 2046

Teck Resources Ltd. will keep digging up copper at its Highland Valley mine in Canada until 2046, adding about 18 years of life to the project to feed growing demand for the metal.

The decision, announced in a statement on Thursday, caps years of discussions on prolonging activity at the site beyond 2028. The extension project will cost between C$2.1 billion ($1.5 billion) and C$2.4 billion, Teck said.
