TIMIKA, Indonesia (AP) — Rescuers have pulled another body from a collapsed facility at a giant U.S.-owned gold and copper mine in Indonesia, bringing the death toll to six.

The Big Gossan underground training facility at the PT Freeport Indonesia mine collapsed Tuesday when 38 workers were undergoing safety training. Ten miners were rescued.

PT Freeport Indonesia says rescuers found the body of a 28-year-old miner buried under tons of rocks and soil early Sunday. They’re searching for 22 others who remain trapped and are feared dead.

Mining operations at the Grasberg mine in the easternmost province of Papua have been suspended since Tuesday to pay respects to the victims and to concentrate on rescue operations. The company said the accident was expected to have no significant impact on its operations.
