Ardea Advances Kalgoorlie Nickel Project with Fully Funded DFS and Strong Government Backing

Largest Nickel-Cobalt Resource Outside Indonesia

Ardea Resources (ASX:ARL) is advancing the Kalgoorlie Nickel Project (KNP) Goongarrie Hub as a cornerstone of secure, diversified nickel-cobalt supply chains. Boasting a massive Mineral Resource Estimate of 854 million tonnes at 0.71% nickel and 0.045% cobalt, the project contains 6.1 million tonnes of nickel, positioning it as Australia’s largest nickel-cobalt resource and one of the few globally significant deposits outside Indonesia.

The Goongarrie Hub’s scale and grade underpin its potential as a long-life operation, with a Pre-Feasibility Study projecting over 40 years of production averaging 30,000 tonnes of nickel and 2,000 tonnes of cobalt annually. The project’s ore reserve stands at 194 million tonnes at 0.70% nickel and 0.05% cobalt, reflecting a robust development base.

Fully Funded DFS with Experienced Japanese Partners

Crucially, the Definitive Feasibility Study (DFS) is fully funded to the tune of A$98.5 million by a consortium led by Sumitomo Metal Mining and Mitsubishi Corporation. These partners bring over 400 years of combined mining history, proven expertise in laterite ore processing and High Pressure Acid Leach (HPAL) technology, and extensive downstream nickel processing capabilities. Their involvement not only secures the DFS funding but also validates the project’s technical and commercial viability.

The Japanese consortium currently holds a 35% interest in the Goongarrie Hub joint venture, with Ardea owning 65%, and has secured 75% of the offtake with rights of first refusal on the remainder, ensuring strong market access aligned with allied battery and critical minerals supply chains.

Multi-Jurisdictional Government Support Accelerates Development

Government backing spans Australia, Western Australia, Japan and the United States, reflecting the strategic importance of the Goongarrie Hub in allied critical minerals frameworks. The project enjoys Major Project Status and Lead Agency Status in Western Australia, streamlined regulatory support via the Australian Government’s Investor Front Door program, and coordinated export finance support from Export Finance Australia (EFA) and the US Export-Import Bank (EXIM).

This multi-jurisdictional support is designed to facilitate financing, approvals and downstream market access, reinforcing the project’s role in securing a stable supply of nickel-cobalt outside Indonesia, which is tightening supply discipline and curtailing ore quotas. The Goongarrie Hub is explicitly recognised in key Australia-Japan and Japan-US critical minerals cooperation agreements, underscoring its geopolitical and economic significance.

DFS Progress and Strategic Milestones in 2026

The DFS is advancing with pre-Front End Engineering Design (pre-FEED) optimisations and engineering studies, maintaining the original $98.5 million budget commitment. While the final DFS report has been delayed beyond June 2026 to incorporate these enhancements and a scandium scoping study, the project fundamentals remain robust.

Recent milestones include the renewal of Major Project Status, the award of Lead Agency Status by the WA Government, inclusion in the Australia-Japan critical minerals joint statement, and the securing of conditional non-binding funding support from EFA and EXIM totaling up to A$1 billion. These developments materially strengthen the pathway toward a Final Investment Decision (FID).

Exploration Upside Beyond Goongarrie Hub

Ardea retains 100% ownership of the broader Kalgoorlie Nickel Project outside the Goongarrie Hub joint venture, including the Kalpini Hub with a resource of 270 million tonnes at 0.76% nickel and 0.05% cobalt. Exploration at Kalpini and the Emu Lake nickel-copper-PGE sulphide discovery offers additional growth potential, including precious and critical minerals such as scandium and rare earth elements.

Financial Position and Leadership

Ardea enters this pivotal phase with a tight capital structure, no debt, and approximately A$19.7 million in cash as of March 2026. The company’s board and management bring decades of combined experience in geology, metallurgy, project development, and corporate governance, supported by a strong shareholder base with the top 40 holding about 62% equity.

The strategic partnership with Japanese industrial giants, robust government facilitation, and the project’s scale and longevity position Ardea well to meet the rising demand for critical battery minerals amid global supply chain realignments.
