Mineral Resources Limited appoints Darren Killeen as new COO amid major growth
Mineral Resources Limited (MinRes) has confirmed the immediate appointment of Darren Killeen as its chief operating officer (COO), a move that centralizes leadership and marks a key succession milestone for the Australian mining giant. Killeen’s promotion underscores MinRes’ ambitious expansion plans, particularly in iron ore and lithium sectors crucial to global supply chains.
With 17 years at MinRes and recent experience as chief executive and head of engineering and construction, Killeen boasts a track record of delivering major projects including the design, construction, and commissioning of the Onslow Iron mine in Western Australia. His deep familiarity with MinRes’ assets and proven ability to execute capital projects on time and budget have earned praise from company leadership.
MinRes Chair Mal Bundey said, “Darren is highly regarded and has built strong and longstanding relationships with our major clients and joint venture partners… delivering projects with an unwavering commitment to safety.”
Mining production targets rise amid strong demand for services
MinRes has upgraded its FY26 (2025-2026 financial year) iron ore production volume guidance to 320-330 million tonnes, up from previous estimates of 305-325 million tonnes. This revision reflects sustained demand and contract renewals in haulage and crushing operations, key components of its mining services division, which has driven significant growth.
Despite weather disruptions in the recent quarter, Onslow Iron mine produced 2.8 million tonnes and shipped 7.2 million tonnes on a 100% basis, sustaining solid performance amid operational challenges.
Strategic moves include housing MinRes’ 50% stakes in premier Australian hard rock lithium mines, Wodgina and Mt Marion, under a newly formed entity called LithCo. This reshuffling positions the company to better capitalize on growing lithium demand vital for batteries and clean energy technology.
Why this matters now
As global demand for critical minerals like lithium surges, particularly from the U.S. and allied markets transitioning to green energy, MinRes’ leadership upgrade and production boosts place the company at the forefront of supplying essential resources. Killeen’s leadership is expected to accelerate project delivery and operational excellence, benefiting investors and customers alike worldwide.
For American readers, the implications extend to raw material availability for electric vehicles, energy storage, and advanced manufacturing that rely on hard rock lithium and iron ore. MinRes’ strengthened management and production outlook highlight an increasing global supply capacity critical to these industries.
Next steps
Investors and industry watchers will closely monitor Darren Killeen’s performance as COO and how MinRes executes on its ambitious production upgrade and operational expansion. Progress in mining services contracts renewal and output from LithCo’s lithium assets will be pivotal in shaping the company’s near-term growth trajectory.
