“All five missing miners confirmed dead after Chile copper mine collapse”, 3 August 2025

All five trapped workers who were missing in a collapsed shaft in the world’s biggest underground copper mine have been found dead, an official said on Sunday.

…

The five miners – Gonzalo Núñez, Jean Miranda, Alex Araya, Carlos Arancibia, and Pávez were trapped deep inside Chile’s El Teniente mine on Thursday after a section collapsed following a 4.2 magnitude earthquake that instantly killed miner Paulo Marín and injured nine other workers.

…

Authorities are investigating whether it was a naturally occurring earthquake or whether mining activity at El Teniente caused the tremor. Chilean prosecutors also launched a criminal investigation to determine whether any safety standards were violated.

…

El Teniente, located in the Andes mountains in central Chile, is the world’s largest underground copper mine and is owned by state company Codelco.

Shortly after Thursday’s collapse, Codelco halted operations in the affected section of the mine and evacuated 3,000 people from the broader site to safe areas.

The company cancelled a presentation of its first-half financial results, set for Friday morning, due to the rescue efforts.
