Australia’s critical minerals sector has spent the past year moving from policy talk to policy action, and this month that shift became harder to ignore. The federal government’s Critical Minerals Strategic Reserve, a $1.2 billion program first flagged in April 2025, is now backed by legislation that has cleared Parliament, with the first tranche of protected materials, antimony, gallium and rare earth elements, chosen because China dominates their global supply. At the same time, Beijing has kept extending its own licensing net over exactly the same materials. For ASX investors, a well funded domestic buyer of last resort meeting a tightening offshore supply chain is turning a niche corner of the market into one of the more closely watched thematics on the exchange.
A reserve that has moved from announcement to legislation
The Critical Minerals Strategic Reserve gives the Commonwealth power to secure offtake rights to minerals produced domestically and on-sell them to allied buyers, acting as a market maker of last resort when private offtake deals stall. Roughly $1 billion is earmarked for transactions through the expanded $5 billion Critical Minerals Facility, with a further $185 million set aside for physical stockpiling. Resources Minister Madeleine King has said the reserve is targeted to be fully operational by the end of 2026, and the enabling legislation has already passed Parliament. Antimony, gallium and rare earths made the starting list because Australia holds identified deposits of all three but limited processing capacity, a gap this site explored when the critical minerals supply chain overhaul was first announced.
Beijing keeps widening its own export net
The urgency behind Canberra’s reserve is easier to understand against what China has been doing with its own export licensing. Beijing has progressively added rare earth elements, along with antimony, tungsten and gallium, to a regime that now reaches beyond raw exports to any foreign made product containing 0.1 per cent or more of Chinese origin material. A second wave of controls covering five additional rare earth elements was due to take effect in late 2025 but has been pushed back to November 2026 under a US-China suspension arrangement. The latest USGS Mineral Commodity Summaries data shows China still accounts for the overwhelming share of processed rare earth output globally, precisely the concentration risk Australia’s reserve is designed to hedge.
The ASX names chasing the antimony and gallium story
A handful of smaller ASX stocks have moved on this policy tailwind. Metallium (ASX:MTM), developing flash joule heating technology to recover gallium, germanium, antimony, rare earths and gold from waste and ore feedstocks, jumped sharply in mid August as investors priced in a faster path to processing revenue. RareX (ASX:REE) has continued advancing its Cummins Range project in Western Australia, which carries rare earths, gallium, scandium and phosphate credits and secured a mining lease earlier this year. Pacgold (ASX:PGO) has been reporting high grade antimony intercepts alongside gold at its St George project in north Queensland, giving it optionality across two of the reserve’s priority commodities. Other explorers with antimony or gallium byproducts have flagged the reserve directly in shareholder updates as a potential offtake counterparty.
Gallium supply gets a rare local boost
Processing capacity, not just resources in the ground, has been the missing piece of Australia’s critical minerals ambitions, so a recent final investment decision to build gallium extraction capacity at a Western Australian alumina refinery is notable. Gallium is typically recovered as a byproduct of alumina refining, and Australia’s large alumina industry means the country could become a meaningful gallium producer without new mines, only new circuits bolted onto existing plants, exactly the kind of brownfield expansion the reserve’s offtake mechanism is designed to underwrite.
Where critical minerals sit in the broader commodity cycle
Critical minerals as a basket behave differently to more familiar bulk and battery commodities. Unlike the lithium price recovery currently playing out, which is driven by supply discipline and restart decisions, antimony and gallium pricing is shaped almost entirely by trade policy and licensing decisions in Beijing and Washington rather than conventional mine supply and demand. That makes the sector more headline sensitive, but it also means Australian projects with clean, non-Chinese supply chains can command a strategic premium unrelated to operating costs. Rare earths, already through this repricing via NdPr, offer the closest template, and the dynamic behind Lynas Rare Earths’ recent record quarter is now being watched for signs it repeats in antimony and gallium.
What it means for ASX investors
The practical takeaway is that the strategic reserve changes the risk profile of early stage antimony and gallium developers rather than guaranteeing anyone a windfall. A government backed offtake option lowers financing risk and can accelerate a project toward a final investment decision, but it does not remove exploration, metallurgical or execution risk. Investors should watch for dilution as smaller companies raise capital to fund studies needed to qualify for reserve support, and distinguish companies with confirmed government engagement from those simply flagging the reserve as a future possibility.
What to watch next
- Confirmation of the first offtake or stockpiling transactions under the Critical Minerals Strategic Reserve once it becomes operational later in 2026.
- Whether China’s delayed rare earth export controls, now pushed to November 2026, take effect on schedule or face a further extension.
- Progress updates from Metallium, RareX and Pacgold on metallurgical testwork and any formal engagement with the federal reserve program.
- Additional brownfield gallium or antimony processing investment decisions at existing Australian refineries and smelters.
Frequently Asked Questions
Which minerals are covered by Australia’s Critical Minerals Strategic Reserve?
The reserve’s initial focus is antimony, gallium and rare earth elements, chosen because China controls the large majority of global processing capacity for all three. The government has said the list of covered materials may expand as the program matures.
Why does China’s export licensing matter so much to Australian critical minerals stocks?
China processes the majority of the world’s rare earths, antimony and gallium, so tighter export licensing directly affects global availability and pricing. That scarcity makes non-Chinese supply, including Australian projects, strategically valuable to manufacturers and governments trying to diversify their supply chains, independent of where spot prices sit on any given day.
