Anglo-Teck $53B merger could topple Escondida as world’s copper leader

The $53 billion Anglo American-Teck merger could create the world’s largest copper mine, surpassing Escondida in Chile by the 2030s. Learn how Collahuasi and Quebrada Blanca will reshape global copper production.

The announced $53 billion merger between Anglo American (LON: AAL) and Teck Resources (TSX: TECK.A, TECK.B, NYSE: TECK) could create the world’s largest copper mine by the early 2030s, surpassing Escondida in Chile, industry analysts say.

The centerpiece of the deal is the integration of Teck’s Quebrada Blanca (QB) mine with Anglo American’s Collahuasi operation. Together, they could produce around one million tonnes of copper annually, experts highlight.

“It is absolutely feasible that a Collahuasi-QB complex could surpass Escondida’s copper output in the early 2030s,” said William Tankard, analyst at CRU Group.

A proposed 15-kilometre conveyor would link Collahuasi’s high-grade ore to QB’s processing facilities, adding the equivalent of a new mine’s output. The system is projected to deliver an extra 175,000 tonnes of copper per year between 2030 and 2049, at lower costs and shorter timelines than a standalone development.

If completed, the combined Anglo-Teck entity would rank among the world’s top five copper producers, with 1.35 million tonnes annually, surpassing Escondida, which produced about 1.28 million tonnes in 2024. The deal would also mark the biggest mining transaction of the decade.

The companies project $800 million in annual pre-tax synergies, and up to $1.4 billion in additional EBITDA gains from shared procurement and operational efficiencies.

“I think it’s conservative,” wrote George Cheveley, portfolio manager at Ninety One. “The optionality to expand and develop that complex over multiple decades is not reflected in that number.”

Operational challenges and risks

However, execution risks remain significant. Teck’s QB mine has struggled with cost overruns, pit instability, plant outages, and waste storage issues. Anglo American, meanwhile, does not fully control Collahuasi, where Glencore and other partners hold significant stakes.

Analysts warn that fixing QB’s operational challenges is critical before the combined complex can compete with Escondida.

According to Wood Mackenzie, Teck’s post-tax value stands at $10.8 billion, broken down as: $13.8 billion from copper, $1.1 billion from zinc, offset by $4.1 billion in central costs through 2040. This estimate excludes potential synergies with Collahuasi, QB’s growth opportunities, and a life extension at Red Dog mine, but factors in downside risk from QB’s operational setbacks.
