Codelco Receives Approval to Reopen Part of El Teniente Mine

The El Teniente copper mine, after a tunnel collapse that killed six workers, is starting to reopen some areas.

Codelco, the company that runs the mine, got permission from the mining safety agency.

However, the labor inspection office still needs to give the final go-ahead.

The approved areas are safe, according to the regulator, but Codelco must watch for any earthquakes.

The collapse damaged a large part of the mine, and investigators are looking at how much was affected.

The mine is very old and has many tunnels.
