Thiess has secured a $700m alliance agreement with Harmony to deliver bulk earthworks, workshop construction and mining services over five years for the Eva copper mine project.

Thiess group and chief executive Michael Wright comments on the alliance agreement.

“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,” he said.

Thiess group executive Australia East Rae O’Brien continues.

“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,” he said.

Early stage works for the project has begun with completion expected in June 2026.

Mining services such as drilling, blasting, mine planning, technical services, mining operations and mobile equipment maintenance across multiple open pits will begin from June 2026 to June 2031.

“The Eva copper mine project is integral to Harmony’s strategic objective to become an international gold and copper producer,” he said.

“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.”
