Harmony’s US$1.6 B Eva copper build: project delivery notes for mine engineers

30 Second Briefing
Harmony Gold is committing US$1.6 billion to build the Eva copper project in Queensland, targeting 100,000 t/y copper output once combined with production from its CSA underground mine in Cobar, New South Wales. The Eva build signals a strategic shift from Harmony’s traditional South African gold base towards long-life copper assets in Australia, adding openpit tonnage to CSA’s high-grade, deep-level stopes. For engineers, the scale and greenfield nature of Eva point to substantial new demand for bulk earthworks, tailings capacity, and high-capacity processing infrastructure in the Mount Isa region.
Technical Brief
- For similar greenfield mining projects, such capex levels typically drive large-scale tailings and haul road construction programmes.
Our Take
Within our 29 Mining stories, copper pieces like this Harmony move are skewing towards Australia and the Americas, signalling that new-build copper capacity is increasingly being pushed into lower sovereign-risk jurisdictions rather than frontier regions.
Harmony’s exposure to copper via Eva complements its existing CSA mine position in New South Wales, which likely gives it regional operating and permitting familiarity that many first-time copper entrants into Australia lack.
Among the 86 tag-matched Projects and Contract Award items, few involve single-asset commitments in the billion‑dollar range for copper alone, suggesting Harmony is positioning Eva as a scale-defining asset rather than a bolt‑on diversification play.
