Global mining services provider Thiess has secured an alliance agreement with Harmony to deliver multiple packages of work at the greenfield Eva Copper Mine Project in Cloncurry, North West Queensland, Australia. This includes bulk earthworks, workshop construction and mining services over five years, with the mining scope valued at approximately A$700 million.
Thiess Group Executive Chair and CEO Michael Wright said: “The Eva Copper Alliance Agreement aligns Thiess and Harmony strategically and operationally – enabling us to set new benchmarks for sustainable, efficient copper development at what will be the largest copper mine in Queensland.
“Thiess' strategy to diversify our commodities portfolio is further progressed with this copper contract award, a critical metal that enables the world’s transition to low emissions energy.”
Thiess Group Executive – Australia East Rae O’Brien said: “We’re pleased to be returning to the Northwest region, the land of the Kalkadoon people, where Thiess has delivered multiple projects across the past 60 years.
“Our alliance with Harmony is underpinned by our deeply aligned values, particularly in supporting local procurement, new-to-industry and Indigenous workforce development, community engagement and a steadfast commitment to safety – we look forward to working together to drive employment, skills development and community partnerships that will endure beyond the mine life.”
Harmony’s Chief Development Officer Johannes Van Heerden said: “The Eva Copper Mine Project is integral to Harmony’s strategic objective to become an international gold and copper producer. Through the Eva Copper Alliance, Thiess and Harmony combine their strengths in a single, integrated framework - leveraging technical expertise, proven industry experience, and shared values to achieve common objectives.
“Our joint project delivery team is fully aligned and committed to operational excellence, with a clear focus on executing the project on schedule and within budget. Safety, transparency, and disciplined delivery are non-negotiable priorities. Thiess brings established systems, proven processes, and deep expertise in bulk earthworks and mining services, supported by a readily available fleet that can mobilise quickly – ensuring we meet our timelines and cost targets without compromise.”
Early stage works for the project are underway, with Thiess having leveraged off the strengths of its companies to commence bulk earthworks and civil works since May 2025.
Upon construction completion, Thiess will provide mining services from June 2026 through to June 2031, delivering drill and blast, mine planning, technical services, mining operations and mobile equipment maintenance across multiple open pits.
