Chilean Regulator Flags Safety Risks at Teck's Quebrada Blanca Dam

Teck's Quebrada Blanca copper mine in Chile has had some problems with its tailings dam, which is like a big wall that holds mine waste.

Workers noticed leaks and a big crack in the dam and told the mining regulator, Sernageomin, about it.

Sernageomin inspected the dam and found a large crack and some water leaks.

They told Teck to report any problems quickly.

Teck said the dam is safe and they fixed the issues.

They are also sending weekly reports to the regulator to make sure everything is okay.

Some people think these problems might be why Teck wants to merge with another company, Anglo American.

The mine's production targets were lowered, and Teck plans to spend money next year to make improvements.
