Greatland’s Havieron Gold-Copper Project Clears Primary Approvals Ahead of June FID

Greatland Resources has moved Havieron from permitting risk into execution planning, securing the primary state and federal environmental approvals required to develop one of Western Australia’s most closely watched gold-copper projects.

The Western Australian Minister for the Environment granted state primary environmental approval on 25 May 2026, following the Commonwealth approval received under the EPBC Act on 24 April 2026. With both primary approvals now in hand, Greatland is targeting a final investment decision in the current June 2026 quarter. 

The timing is important. Havieron is not a remote, stand-alone development looking for a new processing route. The project sits in the Paterson region and is designed as a high-grade underground mine feeding ore into Greatland’s existing Telfer processing infrastructure, creating a development pathway built around a known operating hub rather than a greenfield processing build. 

Early works are already active. Critical-path packages have moved through tendering, including boxcut tunnel installation, underground development and preparation for blind bore construction. The decline tunnel works are intended to reduce water-related risk at the portal and de-risk the long-life Havieron operation against rainfall events. 

The project has strong technical and commercial weight. Greatland’s feasibility work positions Havieron as a long-life underground gold-copper mine capable of leveraging Telfer’s established plant, power, camp, logistics and regional operating base.

The company’s basis of design has considered ramping production from an initial 2.8Mtpa rate toward 4.0Mtpa to 4.5Mtpa, with a crushing and conveying materials-handling system forming part of the current development concept. 

The environmental approval framework also gives the project a clearer development envelope. The Telfer-Havieron proposal includes construction of the Havieron underground mine, associated surface infrastructure, waste rock landforms, evaporation ponds, expanded groundwater abstraction and a 55km haul road to move ore from Havieron to Telfer for processing. The approved framework covers a combined total of 32 million tonnes of ore production. 

Havieron’s value to Greatland lies in its fit with Telfer. The company acquired full control of Telfer and Havieron from Newmont, giving it an operating gold-copper base and a nearby underground growth asset in the same regional system. That ownership structure allows Greatland to frame Havieron as the next source of high-grade underground feed for a processing complex that already has workforce, infrastructure and export pathways in place. 

For the wider mining sector, the approval marks a significant step for a Western Australian gold-copper project moving toward construction in a strong precious-metals price environment. The story also carries weight for underground contractors, drilling groups, ventilation suppliers, ground-support providers, power and water contractors, mobile equipment suppliers and haulage operators because Havieron’s next phase will shift attention from approvals to project delivery.
