  • Rescuers using heavy machinery have cleared approximately 20 meters of debris out of the 90 meters blocking the Andesita section
  • Four miners remain without communication about 900 meters below ground after tunnel collapses cut off radio contact
  • President Gabriel Boric pledged full government support with prosecutors probing whether safety standards were violated
  • Codelco halted extraction in the affected area and evacuated 3,000 people to secure zones following the collapse
