Scandium Supply Risks Loom as Rimfire Advances Fifield Projects

Rimfire’s Strategic Position in Scandium

Rimfire Pacific Mining Limited (ASX, RIM) has released a comprehensive corporate update that underscores its ambition to become a globally significant scandium producer. The company holds the largest scandium prospective landholding in Australia’s premier scandium district around Fifield, New South Wales, a region increasingly recognised as a critical hub for this high-value mineral.

Scandium’s unique properties, lightweight yet strong, make it indispensable in aerospace, transportation, and emerging energy technologies such as solid oxide fuel cells. With global supply constrained and geopolitical risks limiting availability, Rimfire’s exploration efforts position it to meet growing demand from Western economies seeking secure scandium sources.

Advancing Mineral Resource Estimates and Drilling Programs

The company is targeting two new scandium Mineral Resource Estimates (MREs) by the end of 2025 and the first quarter of 2026. The maiden MRE at the Currajong prospect is expected by September 2025, following promising high-grade drill results that include intercepts such as 11 meters at 357 ppm scandium (548 ppm scandium oxide). Concurrently, Rimfire plans to convert the Murga exploration target, estimated between 15,000 and 46,000 tonnes of scandium oxide, into a formal MRE through extensive infill drilling.

Additionally, Rimfire’s 100%-owned Rabbit Trap project is poised for reconnaissance drilling to test strong scandium anomalies identified in historic data. These programs collectively aim to build a robust scandium resource inventory, reinforcing Rimfire’s leadership in Australia’s scandium hotspot.

Joint Ventures and Capital Raising to Fuel Growth

Rimfire has reinstated its earn-in and joint venture agreements with Golden Plains Resources (GPR) at the Fifield and Avondale projects. Under these agreements, GPR can earn up to 70% interest in Avondale and 50.1% in Fifield by funding exploration expenditures, with Rimfire managing operations during the earn-in phase. This partnership structure provides financial leverage and shared expertise to accelerate project development.

To support its ambitious exploration agenda, Rimfire proposes a $3.5 million capital raise through a placement of shares and attaching options. The funds will primarily finance over 5,400 meters of air core and reverse circulation drilling at Murga, assays and MRE completion at Currajong, and initial drilling at Rabbit Trap. The capital raise also secures approximately 12 months of working capital, ensuring operational continuity.

Contextualising Scandium’s Strategic Importance

Scandium remains a niche but critical mineral with no single dominant mine source globally. Its strategic value was highlighted during the Cold War when Soviet aircraft incorporated scandium-aluminium alloys to enhance performance, a technology that Western aerospace sectors have since sought to emulate. Today, scandium’s applications extend beyond aerospace to high-performance transport and clean energy technologies, making secure supply chains a priority for resource-dependent economies.

Within Australia, the Fifield district commands 74% of the country’s known scandium resources, with major players including Rio Tinto, Sunrise Energy Metals, and Rimfire. Rimfire’s exploration success and resource growth potential in this region could position it as a key supplier in a market facing increasing geopolitical and supply risks.

Looking Ahead

Rimfire’s update signals a pivotal phase in its development, with multiple high-impact drilling programs underway and new resource estimates imminent. The company’s strategic partnerships and capital raising efforts provide a solid foundation to advance its scandium projects and respond to growing market demand. Investors and industry watchers will be keenly awaiting assay results and resource confirmations that could reshape the critical minerals landscape.
