Gindalbie Metals has let current CEO Steve Murdoch go, as its combines the roles of CEO and CFO.
According to the company, Gindalbie's current CFO Paul Sims will now step into this combined role.
Murdoch will be leaving the company immediately.
Gindablie's managing director Tim Netscher thanks Murdoch for his efforts as CEO during the Karara iron ore mine's three year construction period and its commissioning phase.
"At its peak Karara was one of the largest construction projects in Australia, employing over 2500 people. It will provide long term employment for over 500 people and opportunity for the Mid-West region.
"Steve [Murdoch's] strong leadership has been absolutely pivotal in delivering this world-scale resource project.
"Now that construction and development are complete, commissioning well-advanced and with Karara now moving to steady-state operations, the board of KML (Karara Mining Ltd) believes this is an appropriate time this transition to occur," Netscher said.
