Newcrest has started the deposition of tailings at the old Cadia Hill open pit following the completion of crucial pipeline infrastructure.
Newcrest had to suspend operations for a period in March this year when the Cadia gold mine saw a breakthrough of tailings material at the northern tailings dam embankment, an incident that Newcrest is still trying to figure out the cause of.
The New South Wales Department of Planning and Environment granted approval for Newcrest Mining to use the first 200m of the old Cadia Hill open pit mine as a facility for tailings storage in April.
The Cadia Hill mine, which had been undergoing a period of care and maintenance, is part of the larger Cadia Valley operations 25km from Orange and 250km from Sydney, one of Australia’s largest gold operations.
Newcrest expects Cadia to return to full production rates before the end of the current financial year. Sandeep Biswas, managing director and chief executive officer of Newcrest, applauded the efforts of the Cadia staff.
“It has been a significant additional challenge to acquire and build the required infrastructures in such short time,” he said.
“Today’s announcement is a true testament to the dedication and commitment of our people, the support we have received from the State Government and local government authorities, and the constructive engagement and support we have received from the Cadia district community.”
