Rescue teams in Chile are racing against time to locate four miners trapped underground following a mine collapse that occurred after a 4.2 magnitude earthquake two days ago. Authorities from the state-owned Codelco company reported the grim discovery of one body at the El Teniente copper mine, situated about 70km (43 miles) south-east of Santiago, the capital. The identity of the victim has not yet been confirmed, but family members of the five missing miners have been notified of the developments.

In a statement, El Teniente's general manager, Andres Music, expressed sadness over the discovery while reiterating confidence in the rescue strategy. "This discovery fills us with sadness, but it also tells us that we are in the right place, that the strategy we followed led us to them," he stated.

Since the collapse of several underground tunnels, efforts to rescue the remaining miners have intensified, with teams deploying heavy machinery to clear blocked passageways. Current estimates suggest that rescuers aim to progress at a rate of 15-20 meters (49-66 feet) every day.

El Teniente is known as the world's largest underground copper mine and is located amidst the high peaks of the Andes mountains in central Chile. As rescue operations continue, hopes remain strong for the safe recovery of the four miners still trapped below.
