In which South American country were thirty-three miners trapped underground for 69 days in 2010?

The event in question refers to the 2010 Copiapó mining accident that took place in Chile, where thirty-three miners were trapped underground for an extended period of 69 days. This incident garnered worldwide attention due to the dramatic rescue efforts involved in extracting the trapped miners from deep within the San José mine, which was located near Copiapó in northern Chile.

The successful rescue operation, which concluded in October 2010, involved a significant amount of planning, engineering challenges, and international collaboration. The miners were trapped approximately 2,300 feet underground after a cave-in on August 5, 2010, and their eventual rescue was celebrated as a remarkable feat, highlighting issues related to mining safety and emergency preparedness.

The other countries listed do not have a similar incident recorded in 2010, making Chile the definitive answer regarding this particular event.
