Rescuers using drone technology have found a light vehicle the workers were believed to be driving when the collapse happened at Dugald River Mine near Cloncurry on Wednesday.

The collapse involved a light vehicle and a drill rig falling into a void at the mine, operated by MMG.

Rescue teams have been trying to locate the two Barminco contractors who were unaccounted for following the incident.

Barminco owner Perenti on Thursday said specialists using drones, void-scanning technology and video imagery had located the light vehicle, and rescue teams were using heavy underground mining equipment to access the location.

Perenti managing director Mark Norwell said the rescue operation would be executed as quickly and safely as possible.

“While the situation is still evolving, we are in contact with the family members of our missing team members and Perenti is providing support to their colleagues and rescue team,” he said.

MMG suspended work at the mine, which employs about 500 people, after the incident.

Inspectors from Resources Safety Queensland have been at the site assisting emergency responders.

Local state MP Robbie Katter said on Wednesday the event was “obviously the worst nightmare” for a mining community and there was a lot of anxiety about the situation.

“We know emergency services are on the ground and we are praying for a good outcome,” he said.
