Chalice Mining's Gonneville Project: A Strategic Pivot in Critical Minerals and Decarbonisation Supply Chains

Chalice Mining's Gonneville Project in Western Australia has emerged as a pivotal player in the global critical minerals landscape, with its pre-feasibility study (PFS) underscoring its potential to reshape supply chains for decarbonization technologies. The project's dual focus on platinum group metals (PGMs) and industrial metals like nickel and cobalt positions it at the intersection of economic viability and strategic resource security, addressing urgent gaps in the transition to a low-carbon economy.

A High-Grade, Long-Life Asset with Strong Financial Metrics

The PFS, released in late 2025, confirms Gonneville as a globally competitive critical minerals development with a 23-year mine life and projected $4.7 billion in pre-tax free cash flow. The project's maiden ore reserve includes 260 million tonnes of material grading 0.86 grams per tonne of 3E precious metals (palladium, platinum, and gold), alongside 0.16% nickel, 0.098% copper, and 0.017% cobalt. Annual production is expected to average 220,000 ounces of 3E metals, 7,000 tonnes of nickel, 8,000 tonnes of copper, and 700 tonnes of cobalt. These figures translate to a pre-tax net present value (NPV) of $1.4 billion and a post-tax NPV of $1 billion, with a pre-tax internal rate of return (IRR) of 23%. Such metrics highlight the project's resilience to commodity price volatility and its alignment with investor demands for robust returns in the critical minerals sector.

Critical Minerals and Decarbonization: A Synergistic Relationship

The Gonneville Project's output directly addresses the surging demand for materials underpinning green technologies. Nickel and cobalt are indispensable for lithium-ion batteries, with each electric vehicle (EV) battery requiring up to 200 kg of critical minerals. PGMs, meanwhile, are vital for hydrogen electrolysis and catalytic processes, with platinum-group metal demand projected to rise 21.7-fold by 2050 under a fuel cell vehicle (FCV)-dominant scenario. The project's production of palladium and platinum, for instance, could support green hydrogen infrastructure, while its nickel and cobalt output aligns with EV battery requirements.

This alignment is particularly significant given the current supply chain bottlenecks. The Global Critical Minerals Outlook 2025 notes that refining capacity for key energy minerals remains concentrated in China, Indonesia, and the Democratic Republic of the Congo (DRC), with the top three producers controlling 86% of refining for these materials. Such concentration heightens geopolitical risks, as export restrictions and geopolitical tensions-such as China's controls on gallium and rare earths-exacerbate supply chain fragility.

Diversifying Supply Chains and Mitigating Geopolitical Risks

Gonneville's strategic value lies in its ability to diversify supply. Currently, PGM production is dominated by Russia, South Africa, and Zimbabwe, while nickel and cobalt are heavily reliant on China and the DRC. By becoming Australia's first primary PGM mine and second-largest nickel producer, the project introduces a new, politically stable source of supply in a region with established infrastructure and regulatory frameworks.

The project's location 70 km northeast of Perth further enhances its logistical advantages, with access to deep-water ports, rail networks, and power infrastructure. This proximity reduces transportation costs and accelerates time-to-market, critical factors in a sector where supply chain delays can amplify price volatility. Additionally, the project's potential for life extension-due to high-grade mineralization beyond current resource models-ensures long-term supply stability, a rare attribute in the critical minerals space.

Strategic Partnerships and Geopolitical Resilience

The project's role in global supply chain security is amplified by the US-Australia Critical Minerals Partnership, which emphasizes integrated supply chain development from exploration to manufacturing-ready material production. This collaboration aims to reduce reliance on single-source suppliers, particularly China, by fostering regional processing capabilities and technological innovation. Gonneville's output could serve as a cornerstone for such efforts, providing raw materials for downstream applications in North America and Asia.

Moreover, the project's environmental and social governance (ESG) commitments-such as a science-based no-net-loss policy for biodiversity and a focus on local employment-align with investor priorities in an era where sustainability credentials are increasingly tied to capital allocation.

Conclusion: A Strategic Investment for the Decarbonization Era

Chalice Mining's Gonneville Project represents more than a high-grade mineral deposit; it is a strategic pivot in the global transition to clean energy. By delivering a diversified mix of critical minerals with strong financial returns, the project addresses both the economic and geopolitical challenges of decarbonization. As demand for green technologies accelerates, Gonneville's ability to supply PGMs, nickel, and cobalt from a stable, infrastructure-rich jurisdiction positions it as a key player in securing the materials needed for a sustainable future.
