Teck is a base metals miner with copper and zinc operations in Canada, the United States, Chile, and Peru. After selling its metallurgical coal business, copper is now its major commodity by EBITDA contribution, followed by zinc. Teck is a top-three zinc miner. Its major new copper mine in Chile at the majority-owned Quebrada Blanca 2, in partnership with Sumitomo, will drive an increase in Teck's attributable copper production by roughly 75%. Along with a number of additional copper growth options, Teck's strategy is to rebalance its portfolio to low-carbon metals such as copper. It sold its oil sands business in early 2023 and its coal business in mid-2024. In September 2025, it agreed to merge with Anglo American.
