Rescue crews searching for five trapped Chilean miners have discovered a body.

A section of the copper mine had collapsed on Thursday following a strong, 4.2-magnitude tremor.

The remaining four miners are still missing – and rescuers are vowing to continue their search with “strength and hope”.

Andres Music, general manager of El Teniente mine, said: “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.”

Crews are trying to drill through 90m (295ft) of rock to reach the trapped miners, but Mr Music said they had not yet made contact with the workers.

Just over a fifth of the blocked underground tunnels have been cleared, with teams hoping to get through about 15m to 20m (49ft to 66ft) every 24 hours using heavy machinery.

He said rescue efforts would continue with increased caution, which could slow progress.

Two people are now known to have died as a result of the collapse.

Another miner, Paulo Marin Tapia, was found dead on Thursday shortly after the incident.

Codelco, which owns the mine, said the identity of the second man is yet to be confirmed.

Nine other miners were injured.
