Critical minerals are no longer a niche corner of the resources sector. Export controls, trade tensions and the rapid build-out of electric vehicles, renewable energy and defence technologies have pushed materials such as rare earths, lithium chemicals and battery intermediates into the centre of geopolitical and industrial strategy.
Rare earth elements illustrate the challenge most clearly. While mining takes place across multiple jurisdictions, the processing and refining steps that turn ore into usable industrial inputs remain overwhelmingly concentrated in China. Similar dynamics apply across battery materials and other strategically sensitive inputs, where dependence is less about where minerals are dug up and more about who controls the midstream.
Governments have responded with a surge of policy initiatives aimed at building non-Chinese supply chains. Investors, too, are being asked to reassess how supply risk, jurisdiction and strategic relevance are priced.
Yet beneath the urgency of the rhetoric sits a more constrained reality. Diversification is possible — but not across every stage of the value chain, and not on political timelines.
That distinction, says Dr Vlado Vivoda from the Sustainable Minerals Institute at the University of Queensland, is often lost in the debate.
Mining is the easy lever — processing is the strategic battleground
At first glance, diversification appears straightforward. New mines can be developed in jurisdictions outside China, particularly in countries with established regulatory frameworks and access to capital markets.
“Mining is the easiest lever to pull quickly because it’s largely about capital deployment and permitting, and we’re already seeing incremental growth in non-Chinese supply (especially in Australia, Canada, parts of Africa and Latin America),” Vivoda said.
But mining alone does little to resolve the strategic vulnerability policymakers are increasingly focused on.
“The bigger strategic scope is in midstream ‘de-risking’ rather than full ‘de-China’,” Vivoda said.
This midstream layer — refining, separation and chemical conversion — is where China’s advantage is most entrenched. In rare earths, mining output is far less concentrated than separation and processing capacity. The same pattern holds across battery materials, where lithium hydroxide, nickel sulphate and precursor chemicals are often produced inside China even when the raw material is mined elsewhere.
Industry analysis supports that view. A recent research note from RK Equity’s Howard Klein argues that the minerals most critical to allied industrial autonomy are often those with the most fragile processing markets — where mine supply alone does little to reduce dependence without parallel investment in conversion and refining capacity.
“Examples include lithium, graphite, nickel (sulphate), cobalt (sulphate), high-purity manganese, non-fertiliser-grade phosphates, and rare earths such as neodymium, praseodymium, dysprosium, and terbium,” Klein wrote.
“These markets are too large for simple stockpiles and too volatile and immature for reliable, long-term hedging.”
Vivoda sees scope for progress, but only in targeted parts of the chain.
“Processing steps that can be modularised, qualified and scaled in OECD and partner economies, particularly refining of lithium chemicals, nickel/cobalt intermediates, rare earth separation capacity and precursor/cathode materials,” represent the most realistic diversification pathway in the medium term, he said.
From policy logic to project execution
That focus is increasingly reflected in how Western-aligned developers on the ASX, including juniors, are advancing their projects. Arafura Rare Earths Ltd (ASX:ARU, OTC:ARAFF, FRA:REB) is progressing the Nolans project in the Northern Territory with an integrated mine-to-oxide development strategy aimed at supplying separated rare earth oxides into allied markets.
Lindian Resources Ltd (ASX:LIN, OTC:LINIF) has moved its Kangankunde rare earths project in Malawi into an execution phase, with recent activity centred on plant orders and processing readiness to convert one of the world’s highest-grade rare earth deposits into a viable non-Chinese supply option.
In the United States, American Rare Earths Ltd (ASX:ARR, OTCQB:ARRNF) has highlighted the size, consistency and domestic location of its Halleck Creek project in Wyoming as Washington intensifies efforts to support US-based rare earth supply chains.
At earlier stages of the cycle, companies are also responding to shifting priorities. Critical Resources Ltd (ASX:CRR, FRA:9S70) has focused recent work on antimony, a commodity that has re-emerged as strategically sensitive amid tightening export controls, while Askari Metals Ltd (ASX:AS2, FRA:7ZG) has strengthened its balance sheet to accelerate exploration across critical metals targets in Africa and Australia.
Recycling will matter — but not yet at scale
Recycling is often presented as a silver bullet for supply-chain resilience, particularly in rare earths and battery materials. Vivoda is more cautious.
“Recycling will matter, but it’s a medium-term volume story: feedstock constraints and collection systems mean it’s more of a resilience and price-stabilisation play than a near-term replacement engine,” he said.
In practice, this means recycling can complement primary supply — smoothing shocks and reducing exposure at the margin — but cannot yet replace the need for new mining and processing capacity.
For investors, that distinction matters. It also reinforces why midstream investment remains the most strategically sensitive — and capital-intensive — part of the diversification effort.
Export controls: Accelerating a shift already under way
Recent export controls and trade restrictions have sharpened attention on critical minerals, but Vivoda argues they have mostly accelerated trends already in motion.
Export controls and resource nationalism have shifted behaviour, he said, “but mostly by accelerating and hardening a behavioural shift that was already in motion”.
“Export controls have moved boardrooms from ‘efficiency-first’ to ‘resilience as a cost of doing business,’ and they’ve pushed governments to treat certain minerals and intermediate products as strategic dependencies, not just commodities,” Vivoda said.
“Resource nationalism has also changed the calculus: it’s increased jurisdictional risk and made downstream players more willing to pay a premium for stable, rules-based supply.”
RK Equity notes that this has sharpened policy focus, with allied governments increasingly concentrating support on materials and processing steps where supply disruption would have outsized economic or strategic consequences — including rare earth magnets and battery precursors — rather than attempting to diversify every mineral at once.
Still, Vivoda cautions that much of what is happening today falls short of full structural change.
“In many cases the policy response is still insurance buying, not full structural change, as firms are diversifying at the margins (second sources, buffers, qualification of alternates) rather than rebuilding entire value chains from scratch.”
That distinction helps explain why many high-profile announcements have yet to translate into bankable projects.
The reality gap: Time, capability and economics
Perhaps the most persistent challenge in building non-Chinese supply chains is the mismatch between political timelines and industrial reality.
“The gap is time + capability + economics,” Vivoda said. “Policy documents assume you can add non-Chinese supply chains into existence on political timelines.”
In reality, the constraints are more practical. According to Vivoda, these include:
- lengthy permitting processes and social-licence hurdles, particularly for new processing facilities;
- shortages of specialist skills and technical expertise, from rare earth separation through to metallisation and magnet quality control;
- long and complex qualification processes, with new suppliers often taking years to be approved in sectors such as automotive, aerospace and defence; and
- ongoing cost challenges, with China’s integrated scale, experience and policy support proving difficult to replicate elsewhere.
The result, he said, is a familiar failure mode: “lots of announcements, not enough bankable offtake, not enough risk-sharing capital, and not enough integration across steps (mine-to-chemical-to-component).”
This is where long-term contracts, financing structures and customer qualification become just as important as geology or process flowsheets — a point increasingly reflected in how companies pitch their strategies.
Australia’s role: Indispensable node, not full-spectrum manufacturer
Australia features prominently in many diversification strategies, but Vivoda urges realism about where the country’s comparative advantage lies.
“Australia’s strongest contribution is credible upstream scale with governance credibility, plus selective midstream where we can be globally competitive: lithium chemicals, certain nickel/cobalt intermediates, and potentially rare earth separation where projects have genuine scale and stable demand,” he said.
“Australia can also be a ‘systems’ contributor: transparent ESG and traceability, reliable contracting, and being a dependable partner for Japan, Korea, the US and Europe.”
That emphasis is visible across several Australian-linked projects. St George Mining Ltd (ASX:SGQ, FRA:S0G, OTC:SGQMF) has recently stepped up its engagement with US policymakers as Washington accelerates its critical-minerals agenda, alongside other Australian companies briefing US officials on supply chain opportunities. International Graphite Ltd (ASX:IG6, FRA:H99), Resolution Minerals Ltd (ASX:RML, OTC:RLMLF, FRA:NC3) and Nova Minerals Ltd (ASX:NVA, NASDAQ:NVA, OTC:NVAAF, FRA:QM3) have all participated in recent US-focused delegations, reflecting growing efforts to position Australian projects within allied critical-minerals strategies.
Where expectations should be tempered is further downstream, according to Vivoda.
“Australia is unlikely to become a full-spectrum manufacturer across the chain (e.g., mass-market magnets, full battery cell ecosystems) on cost grounds alone, unless it’s highly targeted, anchored to strategic demand, and backed by long-term procurement/offtake,” he said.
“The pragmatic lane here is: be world-class where we have comparative advantage, partner for the rest, and avoid trying to build everything everywhere.”
In that framing, success is measured less by national self-sufficiency than by strategic indispensability.
“The win condition is less ‘Australia does it all’ and more ‘Australia becomes the indispensable, trusted node in allied supply chains’ with a few carefully chosen midstream bets that actually clear the commercial bar.”
De-risking, not decoupling
Taken together, the picture that emerges is more nuanced than the headline rhetoric around ‘breaking dependence’ on China. Full decoupling remains unrealistic. What is achievable — and increasingly under way — is targeted de-risking, focused on the most strategically sensitive minerals and the most vulnerable parts of the value chain.
This means projects aligned with genuine bottlenecks, credible customers and realistic timelines are more likely to attract capital, while those built solely on policy enthusiasm may struggle to bridge the gap between ambition and execution.
As competition for critical minerals intensifies, the winners are likely to be those that understand where diversification is possible — and where it is not.
