Jakarta, Indonesia CNN  — 

Emergency workers have recovered all 28 bodies from a collapsed tunnel at an underground mine training facility in Indonesia, the mining company said Wednesday.

Another 10 people were rescued in the aftermath of the accident, which occurred on May 14 about 500 meters from the entrance of the Big Gossan Mine, according to PT Freeport Indonesia, which mines gold, copper and silver in the region. The Indonesian government said a tunnel roof collapsed after a landslide.

The facility is in the eastern Indonesian province of Papua.

“I am deeply saddened and disturbed by this event. Our focus continues to be continuing efforts to gain access to the victims still buried at the accident, carried out as quickly as can be done safely. The entire Freeport family around the world joins Freeport Indonesia in grieving for our lost brothers.”

“With the recovery work completed we are now focusing on reviewing safety throughout our underground operations and in determining what caused the collapse. We will take all actions required to provide for the safety of our work force,” said Richard Adkerson, President and CEO of Freeport.

“Our workforce has always been, and will continue to be, our top priority. Our goal in all our worldwide operations has been to reduce incidents and avoid fatalities. Fatalities are unacceptable for our company.

“We are in the process of assembling an outside investigation team comprised of Indonesian and international experts in underground mining and geotechnical science. We will be transparent in the investigation and its findings and cooperating with the authorities from the Government of Indonesia.”
