About The Project
The Gonneville Project is a critical minerals mine development, located on Chalice-owned farmland approximately 70km north-east of Perth in the Wheatbelt region. The Project hosts a deposit of critical minerals essential for technologies that will help address climate change.
Gonneville will involve construction of an open-pit mine, processing facility and supporting infrastructure to enable extraction and processing of critical minerals.
Why is the infrastructure corridor required?
Like any mine, the proposed Gonneville Project requires a dependable supply of water and electricity to operate. Chalice is proposing a water pipeline and a power transmission line to bring them in from outside the mine area. Together, this off-site infrastructure is known as the Infrastructure Development Envelope (IDE).
The IDE includes a water pipeline to bring treated recycled water from the Alkimos Water Resource Recovery Facility to the mine site, and a 132 kV power transmission line connecting the mine site to the South West Interconnected System at Muchea Substation (approximately 27km).
Both the water pipeline and power line corridors are subject to legislated environmental assessments and landholder engagement processes, which each take into account a broad range of legislative obligations. No works will commence without all required government approvals. The routes for this infrastructure to be constructed have been developed in consultation with government and other stakeholders. These routes will cross over a number of parcels of freehold and crown land.
Where will the infrastructure corridor be located?
The infrastructure corridor connects the Gonneville Project to the Muchea Substation and the Alkimos Water Resource Recovery Facility in an east-west orientation. The infrastructure has been co-located where feasible to minimise environmental disturbance.

When will construction commence?
Before a mine, processing plant and supporting infrastructure can be developed, the Project must receive the approval of State and Commonwealth Governments. Subject to receipt of approvals, Chalice is aiming to make a Financial Investment Decision (FID) to construct the Project in 2028.
Is Chalice consulting with landholders along the corridor?
Yes. In 2025, Chalice undertook a round of direct engagement with landholders along potential infrastructure corridor routes. This included written correspondence, follow-up calls and in-person meetings, and environmental field investigations on properties where landholders gave their consent.
That engagement, alongside environmental data and engineering requirements, informed the identification of the preferred route. Since May 2026, engagement has continued with landholders along the preferred corridor ahead of the planned Miscellaneous Licence application. Chalice will continue engaging with landholders as the Project progresses.

Protecting Aboriginal heritage
Chalice has engaged with Whadjuk Traditional Owners since 2021 with more than 70 Traditional Owners involved in cultural heritage monitoring and surveys across the region. The Project is in the Whadjuk Indigenous Land Use Agreement (ILUA) area (which guides how land is used and how cultural heritage is managed). Whadjuk has conducted Cultural Heritage surveys across the Mine Development Envelope (MDE) and participated in environmental surveys undertaken by Chalice.
Managing environmental impacts
Chalice is committed to identifying environmental impacts and avoiding, mitigating or managing these impacts. The proposal is being assessed at the highest level by the Environmental Protection Authority. Find out more about the assessment process.
