Australia’s Critical Minerals Strategic Reserve is no longer a policy idea floating around Canberra. The enabling legislation has passed Parliament, and the first minerals named for attention are antimony, gallium and rare earths. For investors in ASX-listed critical minerals companies, that is a meaningful shift from talking about supply chain security to building the machinery that pays for it. With China still holding a dominant grip on processing, the question now is which Australian producers and developers are close enough to production to benefit.
A Reserve With Real Legislative Backing
The Export Finance and Insurance Corporation Amendment (Strategic Reserve) Bill 2026 gives Export Finance Australia new powers to secure, sell and stockpile critical minerals and rare earths. The government has said antimony, gallium and rare earth elements are the initial focus. The same legislation also lets the agency underwrite fuel purchases, which shows how closely Canberra now links mineral security with broader economic resilience. We covered the early design of the scheme in our earlier piece on the reserve taking shape as Beijing tightens its grip, and the passage of the bill moves the story from intent to execution.
What remains unclear is timing. The government has not published firm dates for first purchases or stockpiling, and the release does not set out volumes. That gap matters for share prices. Markets have already rewarded some names on the headline, yet the cash flows only arrive once contracts are signed.
Antimony: Small Market, Big Strategic Weight
Antimony is used in flame retardants, batteries and munitions, and the market is tiny compared with copper or iron ore. That is exactly why supply shocks hit hard. Few Western producers exist, and Australia has historically exported concentrate rather than refining it at home.
Larvotto Resources (ASX: LRV) is the standout local story. Its Hillgrove project in New South Wales is being refurbished, with first production targeted for mid-2026 and a direct grid connection that reduces exposure to diesel supply. The company has described itself as one of only two domestic suppliers able to serve the stockpile, and it is weighing a specialist refinery to supply Australian and AUKUS-linked industries. Treat those ambitions with care, because refining projects often take longer and cost more than first planned, and the company has not disclosed offtake or financing terms for any downstream plan.
Gallium and Rare Earths: The Processing Problem
Gallium is a by-product of alumina and zinc processing, and it feeds semiconductors and defence electronics. Australia produces alumina at scale, which is why the metal keeps appearing in bilateral talks with Washington. The Australia and United States cooperation on critical minerals and rare earths supply chains set out a pipeline of projects and shared financing, and a domestic reserve gives those projects a possible buyer of last resort.
Rare earths remain the most developed part of the local sector. Lynas and Iluka already sit at the centre of the debate about independent processing, a theme we explored in our analysis of rare earths at an inflection point. Our coverage of NdPr prices and Lynas shows how sensitive producer earnings are to price floors, which is the very problem a government buyer could help smooth.
Supply and Demand: Why Prices Alone Do Not Tell the Story
Critical minerals do not trade like bulk commodities. Many have thin or opaque pricing, and the Chinese export licensing regime can move availability overnight without any change in underlying demand. The latest Resources and Energy Quarterly from the Department of Industry, Science and Resources remains the best local reference for export volumes and forecasts, and it consistently flags concentration risk across the critical minerals complex.
Global reference data from the US Geological Survey Mineral Commodity Summaries shows how heavily world production of several of these metals depends on a single country. For investors, the lesson is that a project with a credible Western offtaker can hold more value than one with a headline resource and no buyer.
What It Means for ASX Investors
Reserve announcements tend to lift whole sectors briefly, then separate winners from the rest. Companies with permitted projects, near-term production and a clear path to a government or allied customer stand to benefit most. Explorers with early stage drilling results face a longer wait and often rely on equity raisings, which dilute existing holders. Broader context on supply security is available in our guide to what is changing in 2026 for critical minerals supply chains, and our critical minerals hub collects the latest company news.
What to Watch Next
- Publication of purchase volumes, price mechanisms and timing for the first Export Finance Australia stockpile transactions.
- Larvotto’s Hillgrove ramp-up progress and any announced offtake or refinery funding.
- Further Chinese export licensing changes affecting antimony, gallium and rare earths.
- Quarterly production reports and project financing updates from ASX-listed rare earths and critical minerals developers.
Frequently Asked Questions
What is the Critical Minerals Strategic Reserve?
It is a government-backed mechanism that lets Export Finance Australia secure, sell and stockpile critical minerals. Antimony, gallium and rare earth elements are the initial priorities.
Does the reserve guarantee higher prices for ASX miners?
No. The government has not published purchase volumes or pricing terms, so the benefit to individual companies depends on contracts that have yet to be announced.
