Thiess secures $700m agreement for Eva copper project
Thiess secures $700m agreement for Eva copper projectThiess 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.Harmony chief development officer Johannes Van Heerden comments on the Eva project.“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.”

Northern Star maintains $225m exploration budget
Northern Star maintains $225m exploration budgetNorthern Star Resources’ (ASX: NST) FY26 exploration program continues to target near-mine growth across production centres, with spend heavily weighted to the miner’s flagship KCGM operations.The $225m budget is being spent across Northern Star’s three production centres of Kalgoorlie, Yandal and Pogo as well as the newly acquired Hemi development project.The exploration has yielded significant new discoveries of Hercules (Kalgoorlie), Golden Wonder (Yandal) and Star (Pogo).Northern Star managing director Stuart Tonkin comments on the company’s exploration updates.“This update highlights the strong organic growth potential across our global portfolio,” he said.“At Kalgoorlie, drilling and investment are driving growth, with future options to supply high-margin ore to the expanded Fimiston mill from FY27.“At Pogo, new drill drives have enabled extensional drilling, while surface programs advance near-mine opportunities, unlocking high priority targets such as Goodpaster, Star and Central Link.“The integration of our recent strategic acquisition, the Hemi development project, into our gold inventory is underway, with approvals progressing for what is to become our fourth production centre.” Kalgoorlie KCGM operations include the Fimiston open pit (Super Pit), Fimiston and Mt Charlotte underground mines and the Mt Percy project.Drilling has focused on exploration and extensional drilling at the underground operations.Fimiston South highlights further growth opportunities as exploration drilling over the past 12 months has successfully identified mineralisation up to 800m below existing mineral resources.New target ‘Golden Goose’ — north of the Charlotte Fault in Mt Charlotte underground — has highlighted the potential for new mineral resources with results of 73.1m @ 1.9g/t and 25.6m @ 4.0g/t.The Hercules project is focused on the upgrade and expansion of mineral resources outside the existing ore reserve. Infill drilling here has returned thick, high-grade intersections including results of 21.3m @ 6.1g/t and 12.9m @ 9.7g/t. Yandal Successful drilling in Jundee has identified new extensions to Deakin, Barton and Plutus areas with narrow high-grade intersections reported outside the current mineral resources.Surface drilling at Wonder West, within the Thunderbox project region, presents new, strong results from outside the current mineral resource presenting as a new high-grade opportunity. Pogo, Alaska (US) At the Star discovery, a thick high-grade zone was confirmed from a small, surface infill program.Current drilling activities in the Pogo underground mine have focused on testing near-mine extensions opportunities, with strong results returned at East Deep across several high-grade trends.
