Newcrest’s Cadia East Panel Cave 1 recommences production

Global Mining Review,

The remediation and upgrade work required to recommence use of Cadia East’s Panel Cave 1 (PC1) crusher chamber has been completed to a standard consistent with Newcrest’s emphasis on safe, strong and sustainable operations. Extraction of ore has now recommenced from two extraction drives in PC1.

Newcrest has submitted final ground support plans for the PC1 crusher chamber and extraction level to the regulator, and these have been accepted. As a result, the Prohibition Notice has been amended to allow operations to recommence as areas are upgraded in accordance with the submitted plans.

Remediation and upgrade work continues on other areas in the PC1 extraction level, which is expected to be completed by the end of December 2017.

As announced at the time, Newcrest completed the ‘test and response’ phase of the Panel Cave 2 (PC2) on 19 July 2017, with the ramp-up in production from PC2 continuing.

It is expected that Cadia East production rates will have been fully restored to normal by the end of March 2018.
