Mineral Resources (MinRes) has appointed Darren Killeen as Chief Operating Officer, effective immediately.
The creation of a COO forms part of the MinRes Board’s leadership succession process and centralises the company’s leadership structure, with Killeen reporting directly to Managing Director, Chris Ellison.
Killeen has been with MinRes for 17 years.
He most recently served as Chief Executive Engineering and Construction since 2023, a role which saw him leading the delivery of major projects.
This included the design, construction and commissioning of Onslow Iron as well as other large-scale assets which underpin the company’s iron ore, lithium and mining services portfolios.
Ellison said Killeen has been instrumental in delivering the major projects that have transformed MinRes, and the client projects which have built the company’s reputation for execution excellence.
“Darren is highly regarded and has built strong and longstanding relationships with our major clients and joint venture partners,” he said.
“He brings a deep knowledge of our assets, people and culture and has a proven track record of turning strategy into reliable and disciplined capital execution – delivering projects on time, on budget and with an unwavering commitment to safety.”
On behalf of the MinRes Board, Non-Executive Chair, Mal Bundey, congratulated Killeen on his appointment.
“We look forward to Darren’s continued strong contribution to the business as we execute on our strategy,” he said.
