Havieron environmental approval: design and scheduling notes for mine planners

30 Second Briefing
Greatland Resources has secured both Western Australian and federal primary environmental approvals for its Havieron underground gold–copper project, clearing a key regulatory hurdle ahead of a planned final investment decision later in 2025. The permits cover mine development and associated surface infrastructure tied to the nearby Telfer processing hub, enabling Greatland to progress detailed engineering, financing and long-lead procurement. For geotechnical and mining teams, the decision signals that decline development, underground stoping design and integration with existing Telfer plant capacity can now move from concept to execution planning.
Technical Brief
- Environmental conditions will influence placement and design of waste rock landforms and surface water controls.
- Similar WA gold–copper underground projects may benchmark Havieron’s approval pathway for future submissions.
Our Take
The feasibility study for the Havieron gold–copper project released in late 2025 in Western Australia’s Paterson Province pointed to a long-life underground bulk stoping operation, so the new environmental approval effectively clears a key non-technical risk for that development pathway.
Our database shows several recent items on Greatland Resources and Greatland Gold in the Paterson Province, including strong March 2026 quarter results from its 30 per cent Havieron stake and high-grade drilling at Telfer’s West Dome, suggesting the company is building a clustered gold–copper production hub in WA rather than a single-asset play.
With a stated two-year production outlook for Havieron starting later this year, the timing aligns with efforts to extend mine life at the ageing Telfer gold-copper operation, indicating a strategy to smooth regional mill feed and maintain processing utilisation in Western Australia.
