BARBERTON - The Mpumalanga Premier, Association of Mineworkers and Construction Union (Amcu) and the minister of mineral resources say international experts will be called in to the Lily Mine to assess the stability of the ground above the area where three workers remain trapped.

An 80 metre hole is now visible at the entrance of the mine, making the rescue more dangerous.

Amcu has called for the situation at the mine to be declared a national disaster so that additional resources can be deployed to assist in finding the workers.

The rescue mission has been called off temporarily - after this morning's second collapse - and will only resume once rock engineers determine if it's safe to go underground.

Amcu president Joseph Mathunjwa says while the rescue teams that have worked have done a sterling job additional expertise is needed.

Mpumalanga Premier David Mabuza says he will appeal to South Africa's engineering companies for assistance.

The engineers will need to determine if the rescue team can use the same route to reach the container.
