Teck Cominco

Teck Cominco. It is a major Canadian mining and metallurgical company, historically one of the world's largest producers of zinc and a significant producer of copper and steelmaking coal. Formed through the merger of Cominco and Teck Corporation in 2001, the company has a long operational history rooted in the Kootenay region of British Columbia. Its assets have included iconic mines like the Trail Smelter, the Red Dog mine in Alaska, and the Highland Valley Copper mine.

History

The company's lineage traces back to the Consolidated Mining and Smelting Company of Canada (Cominco), founded in 1906 through the amalgamation of several interests by American smelter magnate Augustus Heinze. Cominco's early center was the Trail Smelter, which processed ore from the legendary Sullivan Mine in Kimberley, British Columbia. The Sullivan Mine was a world-class lead-zinc deposit that operated for over a century. Separately, Teck Corporation was founded in 1913 by Keevil family patriarch Norman B. Keevil Sr., initially focusing on gold exploration in Ontario. A pivotal moment for Teck was the discovery and development of the Hemlo gold mine in the 1980s. The 2001 merger of these two entities, orchestrated by Norman B. Keevil Jr., created a diversified mining powerhouse. Subsequent major growth included the acquisition of Fording Canadian Coal Trust in 2008, making it a top steelmaking coal exporter.

Operations

The company's portfolio has spanned base metals, bulk commodities, and precious metals across the Americas. Its integrated zinc business was historically anchored by the Red Dog mine in northwest Alaska, one of the globe's largest zinc producers, whose concentrates were treated at the Trail Smelter. In copper, it operated the Highland Valley Copper mine in British Columbia and held a significant interest in the Antamina mine in Peru, a major copper-zinc operation. Its steelmaking coal operations were centered in the Elk Valley of southeastern British Columbia, with mines like Elkview and Fording River. The company also had interests in gold through its ownership of the Pogo mine in Alaska and development projects like Galore Creek in partnership with Newmont Corporation.

Environmental record

The company's environmental legacy is complex, marked by both significant historical liabilities and modern remediation efforts. The Trail Smelter was the subject of a landmark international arbitration, the Trail Smelter case, between Canada and the United States in the 1930s and 1940s over sulfur dioxide emissions damaging crops in Washington. This case established important principles in transboundary pollution law. In the 21st century, the company faced major challenges related to selenium and calcite leaching from its Elk Valley coal mines into the Kootenay River watershed, leading to ongoing regulatory oversight from Environment and Climate Change Canada and studies on impacts to aquatic life like the Westslope cutthroat trout. It has implemented extensive water treatment facilities to address these issues.

Corporate affairs

The company was headquartered in Vancouver and was a constituent of the S&P/TSX 60 index. For decades, it was controlled by the Keevil family through a dual-class share structure, with Norman B. Keevil Jr. serving as Chairman. A major corporate evolution began in 2023 when Glencore of Switzerland made a strategic investment, acquiring a significant minority stake. This was followed by an agreement for Glencore to acquire the company's entire steelmaking coal business, a transaction that received regulatory approval from the Competition Bureau (Canada) and the Investment Canada Act process. The remaining metals-focused company subsequently reverted to its historic name, Teck Resources.
