Rare Earths Resource and Processing Progress at Splinter Rock
OD6 Metals (ASX:OD6) continues to build its critical minerals footprint with its 100% owned Splinter Rock Rare Earths Project in Western Australia. The company boasts a substantial JORC resource of 682 million tonnes at 1,338 ppm total rare earth oxides (TREO), including a higher-grade core of 119 million tonnes at 1,632 ppm TREO in the Indicated category. Recovery rates for neodymium and praseodymium, key rare earths for permanent magnets, are around 75%, supported by high-quality mixed rare earth carbonate and hydroxide products with low impurities and exceptionally low uranium and thorium content.
Metallurgical testwork has advanced with ANSTO and CPC, including accelerated scale-up testing of 2.5 tonnes of metallurgical core. Ongoing heap leach optimisation, impurity removal via nanofiltration and ion exchange, and bulk product precipitation aim to refine flowsheets and produce customer-qualifiable material. The company is engaging with potential offtake and financing partners while reviewing the potential for selective rare earth oxide production.
Quinn Fluorspar Project Emerges as Strategic US Critical Mineral Asset
In the United States, OD6 has completed acquisition of the Quinn Fluorspar Project in Nevada, covering 226 mining claims across 4,670 acres. The project hosts a district-scale epithermal system with multiple high-grade fluorspar occurrences, including Horseshoe, Big Jim, and Mammoth deposits. Historic and recent sampling confirm exceptional fluorspar grades, with channel samples at Horseshoe averaging above 60% CaF2 and peak drill intercepts exceeding 80% CaF2. The company is targeting both Metspar (60–96% CaF2) and premium Acidspar (>97% CaF2) products, essential for applications ranging from steel and aluminium production to advanced battery technologies and defence.
OD6's metallurgical program integrates mineralogy, grind optimisation, flotation, and ore sorting technologies, notably TOMRA laser sorting, which has demonstrated clear discrimination between high-grade ore and waste. This supports a potential low-CAPEX direct shipping ore pathway. Permitting is underway alongside assay programs and geological modelling to prioritise drill targets. The fluorspar market is forecast to grow amid US import reliance and government initiatives such as the FAST-41 permitting pathway and Project Vault stockpiling, positioning Quinn well for strategic support.
Gulf Creek Copper Project Shows Encouraging Drill and Geophysical Results
OD6's Gulf Creek Copper Project in New South Wales also advances with promising early-stage results. Phase 1 drilling has confirmed copper grades up to 4.6%, with historical production reaching 12% Cu. A down-hole electromagnetic survey has identified strong conductors beyond drill hole endpoints, suggesting potential extensions of high-grade mineralisation. Geological reinterpretation points to fault offsets of historic lodes, and multiple high-priority targets remain open along a 3 to 10-kilometre VMS horizon. Drilling campaigns continue through 2026 to delineate resources.
Strategic Positioning Amid Government Support and Market Demand
OD6’s portfolio aligns with global and domestic priorities for critical minerals supply chains. Fluorspar is officially designated a US critical mineral, with the country highly import-dependent, sourcing predominantly from China, Mongolia, and Mexico. The US government’s initiatives including federal loan programs, strategic offtake agreements, and significant investment under the CHIPS Act and Inflation Reduction Act provide a supportive backdrop. Similarly, Australia’s A$1.2 billion Critical Minerals Strategic Reserve underscores the sector's strategic importance.
The company’s fluorspar grades compare favourably with peers such as Tivan Ltd’s Speewah Project, potentially enabling lower capital and operating costs. OD6’s focus on multiple commodities, rare earths, copper, and fluorspar, positions it to capitalise on the accelerating demand driven by electrification, battery technologies, defence readiness, and industrial resilience.
Development Pathway and Upcoming Catalysts
OD6 plans to progress its projects through systematic exploration, drilling, and metallurgical testwork. At Quinn, pending assay results and bulk sampling permit applications will inform maiden drilling programs and resource definition. At Splinter Rock, further scale-up testwork and offtake discussions are key. Gulf Creek drilling continues to refine geological models and target prioritisation. Investors should watch for assay releases, permitting milestones, and offtake agreements that will clarify the commercial potential and capital requirements ahead.
Bottom Line?
OD6 Metals is methodically advancing a diversified critical minerals portfolio, but project valuations hinge on upcoming assay results, permitting progress, and successful offtake partnerships.
Questions in the middle?
- Will assay results confirm the scale and grade continuity needed for commercial development at Quinn and Splinter Rock?
- How will OD6 navigate permitting timelines in the US and Australia to maintain project momentum?
- What are the prospects for securing strategic offtake and financing agreements amid shifting critical minerals geopolitics?
