Defence-driven demand reshapes surge of mining firms listing in U.S. markets

Mining companies are increasingly using U.S. stock market listings to underline their role as potential suppliers to defence supply chains rather than relying solely on traditional mining narratives about supply-demand fundamentals and long-term price cycles. This year, at least 18 companies - mostly from Canada and Australia, with some U.S. start-ups among them - have completed or are pursuing dual listings on U.S. exchanges, a sharp rise from three such listings in 2025, based on exchange filings and company disclosures.

The recent transactions have brought producers of minerals the Pentagon designates as strategic - including antimony, rare earths, tungsten and uranium - to exchanges such as the New York Stock Exchange and Nasdaq. Company filings show many of these miners are explicitly positioning themselves as suppliers of inputs used in munitions, armour-piercing materials and components for U.S. weapons systems, marking a notable shift in how they present themselves to investors.

One firm that has made defence demand central to its messaging is Guardian Metal Resources. In filings and public statements the company says its objective is to meet direct defence demand for tungsten, and the firm’s chief executive, Oliver Friesen, has estimated U.S. military annual consumption at about 2,000 to 3,000 metric tons. Guardian reports it has received $6.2 million from the Pentagon and has applied for additional U.S. military funding that would be worth at least $100 million, as indicated in company disclosures.

Other companies have similarly linked their projects to defence use-cases. United States Antimony has secured a $245 million Defense Logistics Agency contract to provide antimony to the defence stockpile, where the metal is used in munitions and other military applications. Rare earth developers are emphasizing defence applications as well: REalloy Inc has indicated its project contains dysprosium and terbium, elements used in high-performance magnets for advanced weapons systems; Rare Earth Americas, which has backing from Australian investor Gina Rinehart, has partly focused its U.S. offering on defence applications.

While the headline announcements often highlight listings, the amounts raised in traditional equity offerings to date have tended to be modest. Company filings show Guardian secured $68.3 million, Rare Earth Americas raised $63.3 million, and Atlas Critical Minerals reported roughly $11 million. Yet several firms have also tapped government-funded programs tied to the U.S. military, suggesting the listings serve a dual purpose: opening access to U.S. capital markets and unlocking strategic financing and procurement opportunities tied to defence programs.

Companies and U.S. listing moves cited in company disclosures include:

Beyond listings and IPO proceeds, some Canadian-listed miners are also engaging with U.S. defence-linked finance through direct equity stakes or project funding arrangements. Firms such as Lithium Americas and Trilogy Metals have been referenced in disclosures as tapping these defence-linked financing channels. These arrangements are part of a broader U.S. policy push to rebuild domestic mineral supply chains and reduce reliance on China for production and processing.

The backdrop to many of these corporate moves includes a series of policy and market developments. China imposed export controls on antimony in August 2024, tightening global commercial supply for a mineral used in military equipment and intensifying concerns about defence supply chains. A subsequent 2025 Chinese export ban on tungsten restricted feedstock for U.S. refineries, which historically were built for different industrial uses and now operate well below their nameplate capacity, according to company statements.

By December 2025 the U.S. military had begun testing small-scale refineries for critical minerals, a shift from funding projects to building processing capacity itself. In November 2025 China issued a one-year suspension of its export ban on antimony, gallium, germanium and super-hard materials to the U.S., while maintaining restrictions on military users. That eased some commercial supply, but filings and public comments indicate the Pentagon remains focused on securing domestic sources for the military supply chain.

Washington has also faced other supply risks, including restrictions on cobalt exports from the Democratic Republic of Congo, noted in company and policy briefings. Those constraints have helped drive private capital toward defence-oriented mineral projects and have pushed some investors and banks to consider larger commitments to the sector.

Private finance responses include statements from major banks and new government-backed initiatives. JPMorgan told investors it could deploy up to $10 billion into sectors tied to national economic security, including critical minerals. In February, the U.S. administration announced "Project Vault", a $12 billion strategic minerals stockpile initiative, backed largely by the U.S. Export-Import Bank, according to government disclosures. The administration has also taken equity stakes in mining companies, including MP Materials, USA Rare Earth and Korea Zinc, as part of a broader policy toolkit designed to underwrite supply chain resilience.

Analysts and lawyers say government equity and programme funding can provide more than cash: they can open doors to defence contracts, subsidies and policy support that help companies manage the cyclical risks intrinsic to commodity markets. Yet not all participants are sanguine about the near-term prospects for large-scale industry restructuring. "There’s absolutely a lot of money going into defence-driven exploration, but a lot of it is also very speculative right now," said Rick Werner, co-chair of the capital markets and securities practice at Haynes Boone. He added that, while securing access to mines and resources could help break what some describe as China’s dominance in certain minerals, doing so will require significant time and investment.

For now, listings, modest equity raises and defence-linked contracts and funding appear to be the immediate objective for a growing number of mineral producers. Those steps are intended to pair access to U.S. capital markets with strategic financing pathways tied directly to defence procurement and stockpile initiatives.

Key takeaways

• At least 18 mining companies have pursued or completed dual U.S. listings this year, up from three in 2025, with many highlighting defence end-uses for critical minerals.
• Companies producing antimony, rare earths, tungsten and uranium are explicitly targeting defence demand and in some cases have secured Pentagon-related funding or contracts.
• Listings are being used not only to raise equity but to access defence-linked financing, procurement opportunities and policy support that can supplement modest IPO proceeds.

Risks and uncertainties

• Supply-chain constraints and export controls - Policies such as China’s export curbs on antimony and tungsten have tightened feedstocks and could continue to create volatility for downstream processing and project economics.
• Speculative financing risk - Legal and market advisers note that much defence-driven exploration financing is speculative at present, and successful scaling to meaningful domestic production will require substantial capital and time.
• Policy and procurement dependency - Companies that rely on defence-linked funding and contracts face uncertainty tied to shifting policy priorities and the timing of government procurements.
