Chalice Mining has outlined the development strategy for its Gonneville nickel-copper-platimum group element (PGE) project located north-east of Perth in Western Australia.
The company remains on schedule to deliver its pre-feasibility study (PFS) in the fourth quarter of 2025, with draft environmental review documents (ERDs) on track for submission in mid-2026.
The proposed development includes a long-life bulk open-pit mine, beginning with a smaller-scale processing operation in the first four years, followed by an expansion from year five.
Stage 1 is focused on achieving the highest rate of return and the quickest capital recovery, while Stage 2 is structured to maximise long-term strategic value throughout fluctuations in metal prices.
A referral submitted to regulators in early 2024 supports a processing throughput of up to 15 million tonnes per annum.
Chalice has also executed a letter of intent to secure process water from the Water Corporation’s Alkimos facility, with plans to transport it via pipeline to site.
Renewable power options are being explored, including a hybrid solar and battery solution, alongside a new 132kV transmission line and long-term power purchase agreements.
The final project scope and site layout has enabled commencement of environmental modelling and impact assessments with leading consultancy GHD conducting the environmental modelling to support key approvals.
Environmental surveys for the power and water corridor are scheduled for the second half of 2025.
Chalice continues to engage with state and federal governments on potential shared infrastructure and funding opportunities.
As of March 31, the company held $83 million in cash and listed investments, fully funding the project through to a final investment decision expected in late 2027.
