Australian Mines has reaffirmed strong economics for its Flemington Scandium Project, highlighting a robust 28-year mine life and significant leverage to scandium price scenarios.
- Post-tax NPV8 of US$860 million at US$3,000/kg Sc₂O₃
- 28-year mine life with high-grade scandium feed
- Initial capital cost estimated at US$125 million
- Breakeven scandium price at US$815/kg with 90.8% recovery
- Funding of US$125 million pre-production capital required
Flemington Scoping Study Validates Long-Life, Low-Cost Scandium Operation
Australian Mines Limited (ASX:AUZ) has released an amended version of its Flemington Scoping Study, confirming the project's strong economic fundamentals remain intact. The study underlines a substantial 28-year mine life based on a 6.3 million tonne Mineral Resource grading 446ppm scandium, with an average feed grade of 573ppm over the first 15 years. Despite the re-release providing additional disclosures and clarifications, the core outcomes remain unchanged.
The Scoping Study, prepared by SRK Consulting, projects a post-tax net present value (NPV8) of approximately US$860 million and an internal rate of return (IRR) of 74% under a market-aligned scandium oxide price of US$3,000 per kilogram. This price is used for sensitivity analysis and valuation purposes, while the mine design itself is based on a more conservative US$1,500/kg Sc₂O₃ price, yielding a post-tax NPV8 of US$270 million and IRR of 32%. These figures highlight the project's significant leverage to scandium pricing volatility.
Capital and Operating Costs Reflect Low-Intensity Development
Flemington's initial capital expenditure is estimated at US$125 million, primarily allocated to the processing plant and supporting infrastructure, including a tailings storage facility. This capital intensity is considered low for a scandium operation, with sustaining capital over the life of mine pegged at US$18.2 million. Operating costs are competitively positioned, with a C1 cash cost of US$561 per kilogram of scandium oxide and a breakeven price of US$815/kg, underscoring robust margin potential even under conservative pricing assumptions.
The project benefits from simple, low-risk mining methods involving three shallow, free-dig open pits with a stripping ratio of approximately 1.9:1. Processing employs a conventional hydrometallurgical flowsheet featuring high-pressure acid leach (HPAL) technology, achieving a scandium recovery rate of 90.8%. Notably, nickel and cobalt by-products contribute marginally to revenue, approximately 4%, and are not material to the investment case.
Strategic Location and Upside Optionality
Situated in central New South Wales, Flemington lies contiguous to the Syerston Scandium Project and benefits from established regional infrastructure and road networks. The project’s proximity to existing mining services supports a streamlined development pathway. Additionally, there is potential upside from approximately 410,000 tonnes of lower-grade scandium material currently classified as waste, which may be stockpiled or processed in future expansions, potentially reducing the effective stripping ratio to 1.4:1.
Australian Mines’ CEO Andrew Nesbitt emphasised the project's strategic positioning within a scarce group of globally significant scandium assets, noting its combination of high grade, low capital intensity, and straightforward development route. The company sees Flemington as poised to capitalize on increasing strategic demand for scandium, particularly in secure Western supply chains, given recent Chinese export controls and sovereign procurement activities such as the U.S. Defense Logistics Agency's scandium acquisition plans.
Funding and Development Pathway
The study assumes pre-production funding of approximately US$125 million will be required to advance the project through pre-feasibility and feasibility studies. However, no funding has yet been secured, and there is no certainty that such capital will be raised on acceptable terms. Australian Mines may consider alternative value realisation strategies, including partial sales or joint ventures, which could dilute its ownership stake.
The company recently secured a $3 million strategic placement led by Tribeca Investment Partners to accelerate the Flemington project towards the Pre-Feasibility Study phase, supporting further technical work and permitting efforts. This injection is a step towards de-risking the project ahead of larger funding requirements, building on the strong economics outlined in the scoping study and its sensitivity to scandium pricing scenarios Strategic $3M placement led.
Market Sensitivity and Risks
The scandium market remains immature and opaque, with limited transparent pricing data and variable transaction prices. The study’s market-aligned price of US$3,000/kg Sc₂O₃ is a sensitivity case, not a forecast, reflecting reasonable grounds based on peer project disclosures such as the neighbouring Syerston Project, which also uses US$1,500/kg as a base case and US$3,000/kg as a sensitivity. North American projects reportedly use even higher price assumptions around US$3,700/kg. These factors illustrate the potential for significant upside but also underline the project's exposure to commodity price volatility.
Key risks include metallurgical performance, water supply definition, permitting and approvals, absence of binding offtake agreements, and exchange rate fluctuations. Further metallurgical test work, environmental baseline studies, hydrogeological investigations, and market engagement are planned to address these uncertainties and advance the project towards development decision-making Robust economics in Flemington Scoping Study.
Next Steps and Study Advancement
Australian Mines intends to progress Flemington through Pre-Feasibility and Feasibility Study phases, with an indicative two-year pre-production period before ore processing commences. The Pre-Feasibility Study is expected to take approximately 6 to 9 months and will focus on refining mine design, processing flowsheet, infrastructure, and funding strategies.
The company will also conduct further metallurgical sampling to confirm recovery assumptions, optimize processing, and validate product quality. Environmental and social baseline studies will support permitting, while ongoing market and customer engagement will aim to secure offtake agreements and strengthen the commercial case.
Bottom Line?
Flemington’s economics hinge on securing funding and navigating an opaque scandium market, with the next year critical for technical validation and commercial positioning.
Questions in the middle?
- How will Australian Mines secure the estimated US$125 million pre-production funding amid market uncertainties?
- Can further metallurgical test work confirm the assumed 90.8% scandium recovery across the broader resource?
- What impact will global scandium market dynamics and geopolitical factors have on pricing and offtake negotiations?
