This contract extension reflects our commitment to delivering high-quality asset integrity services and supporting Indonesia’s growing nickel industry – an essential contributor to the global energy transition. Critical minerals like nickel are foundational to clean energy technologies, defence systems, and digital infrastructure. Through Leighton Asia’s expertise and our Group’s integrated capabilities, we are proud to play a role in securing the supply chains that underpin these strategic sectors.”
Leighton Asia Managing Director Brad Davey said: “This extension highlights Leighton Asia’s capabilities and reinforces our role in enabling sustainable development in Indonesia. As part of CIMIC Group, we bring deep experience in resources infrastructure and critical minerals delivery. We are proud to contribute to the success of this significant project and the region’s economic and technological growth and are humbled by the trust placed in us by our client PT Vale Indonesia.”
Work under the extended contract is scheduled to commence in Q4 2025 and complete in Q4 2028.
