A tragic week for Chile has come to a heartbreaking end as authorities confirmed on Sunday that all five workers who remained trapped inside the El Teniente copper mine have been found dead. This brings the total fatalities to six following the partial mine shaft collapse that occurred after a 4.3 magnitude earthquake shook the O’Higgins Region.
Chile Mine Collapse
The Chile mine collapse at El Teniente—one of the world’s largest copper mines—was triggered by seismic activity last Thursday. The collapse initially claimed one life and left five miners buried under an estimated 20 meters of debris. After days of intense rescue efforts, the body of the last trapped miner was recovered, concluding the operation.
Government and Codelco Response
President Gabriel Boric confirmed the grim news on Sunday, expressing deep sorrow and declaring three days of national mourning. “Codelco’s heart is damaged,” said company chairman Máximo Pacheco, who emphasized the pain shared by workers and the community alike.
Rubén Alvarado, CEO of Codelco, had earlier warned that the first 48 hours were critical in locating the missing miners alive. Rescue teams worked around the clock, facing complex conditions due to the sheer volume of debris and ongoing structural concerns.
Earthquake and Collapse Details
According to the National Seismological Center of the University of Chile, the quake struck with a magnitude of 4.3, leading to the collapse of a shaft within the mine. In addition to the six confirmed deaths, nine other miners sustained injuries.

The tragic event has deeply shaken the mining community. Edgar Rodrigo Quesada, a former union leader, noted that although emergency shelters exist in the mine, they are far from the site of the collapse. Fellow miner Abelardo Céspedes expressed a sentiment echoed across the region: “We just trust in God, and maybe a miracle will happen.”
Despite these hopes, the recovery of the last body has marked a devastating end to a high-stakes rescue mission.
El Teniente’s Significance and Impact
Located in central Chile’s O’Higgins Region, El Teniente is the largest known copper deposit in the world. The halt in operations following the collapse may have economic implications for Chile, where mining remains a backbone of national exports.
This incident revives painful memories of past mining disasters in the region and reignites conversations about workplace safety and infrastructure resilience in seismic zones.
Conclusion
The Chile mine collapse at El Teniente has left a nation in mourning. As investigations continue and questions are raised about mine safety standards, the focus remains on supporting the families of the victims and preventing future tragedies.
