100% of the Eva copper project, an iron oxide-copper gold resource, together with 16 exploration tenements, was acquired in December 2022. Following the completion of the feasibility study, a board decision was made in November 2025 to proceed with construction.
The project is poised to become the largest copper mine in northwest Queensland, Australia, and extends Harmony’s diversification into copper, a future-facing metal critical to the energy transition. First production is expected in the second half of 2028.
