At the core of one of the mining sector’s most ambitious deals is a plan to revive Teck Resources Ltd.’s troubled copper operation in Chile’s Atacama Desert and merge it with Anglo American Plc’s vast neighboring assets, Bloomberg reported. The proposed more than $50 billion transaction aims to reshape copper production in one of the world’s richest mining regions but hinges on resolving significant technical and operational difficulties at Teck’s Quebrada Blanca (QB) mine.
Bloomberg’s sources note that Teck’s QB project, which has long been central to the company’s growth plans, has faced persistent setbacks since its inception. The mine’s construction was over 80% above budget and years behind schedule. Since then, it has been beset by instability in the pit and processing plant, failures at its ship-loader, and waste storage complications. These troubles forced Teck to cut production guidance earlier this year and delay decisions on expansion in order to focus on repairing the site.
“Quebrada Blanca has sizable technical challenges to reach capacity,” Juan Ignacio Guzman, head of Chile’s mineral consulting firm GEM, told Bloomberg. “The synergies it could have with Collahuasi aren’t simple.”
The integration with Anglo’s operations will require navigating governance complexities due to multiple partners in the Collahuasi mine, where Anglo lacks full control. “Among the challenges will be governance, due to the multiplicity of partners,” Juan Carlos Guajardo, founder of Plusmining, explained to Bloomberg.
Anglo’s Chief Executive Officer Duncan Wanblad told analysts this week that the company is carefully evaluating the technical hurdles. Anglo has dispatched specialists to QB and consulted independent engineers to ensure it fully understands the risks involved before proceeding with the merger.
Yet the deal’s structure has sparked concern among investors. Some Teck shareholders worry that Anglo is acquiring a distressed asset at a bargain price, while Anglo’s investors fear they may be inheriting deeper issues than anticipated. “It’s beyond me why Teck would surrender control of one of the world’s great copper-rich mining companies for nil premium, especially when they’ve inexplicably chosen to price the deal after underperforming Anglo by so much,” Tim Elliott, head of mining at Regal Funds Management, told Bloomberg. “Teck should fix their key asset first, then test the market properly from a position of strength.”
On the ground, operational problems have affected workers’ livelihoods. Union representatives reported filling cracks around the mine’s tailings dam and dealing with waste buildup from filtering issues and corroded pipes. The delayed ramp-up has also reduced production bonuses. “This hits the wallet,” David Munoz, a union official, told Bloomberg. “We don’t do less work than at other mines but we get less because of these issues.”
To address the challenges, Teck recently appointed a former senior BHP executive as a special adviser to tackle tailings issues. The company is focusing on raising the tailings dam wall and improving sand drainage times. In a statement to Bloomberg, Teck emphasized that dam and pipe maintenance is a routine process and poses no immediate safety risk.
Wanblad compared the situation at QB to challenges faced at Anglo’s own Quellaveco project in Peru, highlighting that supply expansions in the copper industry often take longer than expected. “The reality is that these major operations do just sometimes take time,” he said, according to Bloomberg.
As demand for copper surges with the transition to greener technologies, the outcome of the Anglo–Teck deal will likely have far-reaching implications—not only for the companies involved but for the global supply chain as a whole.
