Cadia has been shaken by another seismic event.

Nobody was hurt.                                                 

In accordance with standard operation procedure all personnel working in the affected area were accounted for and safely returned to the surface.

The New South Wales Resources Regulator has issued a prohibition notice around the affected area.

The prohibition has not extended to other areas of the Cadia East mine or surface areas and there have been no impacts to Panel Cave 2-3 development activities.

Mining operations in all other areas, development activities and above-ground operations continued uninterrupted.

The replacement of the semi-autogenous grinding mill motor for Concentrator 1 started on July 5 as planned.

Inspections have confirmed the ground support Newcrest installed prevented damage to infrastructure. The only damage was localised damage to the roadways and ground support near the junction of two extraction drives and minor ground support damage to a nearby ventilation rise.

Newcrest is working with the regulator and will be sending it a geotechnical report as part of efforts to gain approval to restart operations in the affected area.

The company said in a statement to the Australian Securities Exchange that the seismic event was not expected to have an impact on gold or copper production for the 2021-22 financial year.
