Grange Resources' Savage River mine has seen a rock slide at its Tasmanian Savage River mine that ran for more than two days.
According to the company "a rock slide commenced on the eastern wall of the North Pit….in the early hours of Wednesday 18 July and concluded early [Friday]".
However as the mine had geotechnical controls in place which notified them of the potential for a wall failure there were no workers or equipment in the area.
"No personnel were exposed to any danger as a result of the slip and no injuries were sustained," Grange stated.
As a result of the incident it has redeployed operations to alternate locations around the mine, with production to be maintained at normal planed levels while its mine plans are reviewed.
The miner said that "at this stage the slip is not expected to have a material adverse effect on the operation and it is anticipated that the 2012 production target is not materially at risk".
Workplace Standards Tasmania was notified soon after the event, and it approved the continuation of operations.
In 2010 the mine recorded another large rockfall at the same area, when around 140 000 cubic tonnes of rock fell into the pit.
Grange explained the latest rockfall event, stating that "the geotechnical environment at Savage River is well understood and the structure is such that slips will occur from time to time"
