The Super Pit’s general manager Russell Cole has left the top job in unexplained circumstances.
The change is effective immediately, however the reason behind the move has been left a secret by Kalgoorlie Consolidated Gold Mines (KCGM)
"The JV partners and Russell have agreed to make a management change in relation to the KCGM general manager's position," a spokeswoman said.
"The detail behind this decision is a confidential business matter between the JV partners and Russell."
Cole has been general manager of the mine since 2006, but has worked for KCGM since 1998.
The spokeswoman thanked Cole for driving innovation during his tenure, including key improvements in safety and productivity.
KCGM operations manager Ian Butler will become acting general manager.
The Super Pit is managed by KCGM and owned (50/50) by Newmont Australia Pty Ltd and Barrick Australia Pacific.
