LONDON, May 27 (Reuters) - There has been a surge in mining companies seeking U.S. listings this year, but even more striking is the change in language as firms explicitly target defence-related demand for critical minerals.

At least 18 companies, mostly Canadian and Australian but also some U.S. startups, have completed or are pursuing dual U.S. listings this year, versus just three in 2025, according to exchange filings and company disclosures reviewed by Reuters.

They span in value from about $25 million to $7.5 billion and mark a shift in how critical mineral producers seek access to capital markets as listings explicitly pitch for defence end-use applications.

DEFENCE FOCUS

This year's transactions have brought producers of antimony, rare earths, tungsten and uranium to the NYSE and Nasdaq - all minerals designated strategic by the Pentagon and used in fighter jets, missiles and radar systems.

The firms are positioning themselves as suppliers of munitions, armour-piercing materials and of inputs for U.S. weapons systems, their public filings show, departing from traditional mining IPO language focused on supply-demand fundamentals and long-term price cycles.

"Our goal is to cover direct defence demand for tungsten," Guardian Metal Resources GMTL.K, GMTL.L CEO Oliver Friesen told Reuters, estimating U.S. military annual demand at 2,000 to 3,000 metric tons.

Guardian aims to help the U.S. rebuild its domestic tungsten supply chain, citing uses in armour-piercing ammunition. It has received $6.2 million from the Pentagon and has applied for additional funding from the U.S. military that would be worth at least $100 million, Reuters reported in March.

United States Antimony UAMY.N secured a $245 million Defense Logistics Agency contract to supply antimony for the defence stockpile, where the metal is used in munitions and other military applications.

Rare earth developers are also emphasising defence uses. REalloy Inc ALOY.O said its project contains dysprosium and terbium used in magnets for advanced weapons systems, while Rare Earth Americas, backed by Australia's Gina Rinehart, partly focused its IPO on "defence applications".

Most companies have raised modest sums so far. Guardian secured $68.3 million, Rare Earth Americas REA.O $63.3 million, and Atlas Critical Minerals ATCX.O about $11 million, according to filings.

But several have secured government funding through Pentagon-linked programs, suggesting the listings are as much about unlocking strategic financing and investor access as upfront capital raising, analysts and lawyers said.

EQUITY STAKES, PROJECT FUNDING

Some Canadian-listed miners, including Lithium Americas LAC.TO and Trilogy Metals TMQ.TO, are tapping U.S. defence-linked financing through equity stakes and project funding as part of Washington's push to secure key minerals.

That push follows a series of crises that left the United States and other Western nations racing to rebuild domestic mineral supply chains and reduce their dependence on China's dominant production and processing.

China imposed export controls on antimony in August 2024, tightening global supply of a mineral used in military equipment and raising concerns about U.S. defence supply chains.

By December 2025, the U.S. military had begun testing small-scale refineries for critical minerals, shifting from funding projects to building processing capacity itself.

A 2025 Chinese export ban on tungsten has limited feedstock for U.S. refineries built in the 1950s for filament light bulbs, which have production capacity of about 18,000 tons but are operating significantly below that, Guardian's Friesen said.

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., but kept restrictions on military users, easing commercial supply but leaving the Pentagon reliant on domestic sources.

In addition to China's export curbs, Washington has faced restrictions on cobalt exports from the Democratic Republic of Congo and other risks.

CAPITAL FOLLOWS POLICY

Private capital has also responded. JPMorgan, for example, said in October it could invest up to $10 billion in sectors tied to national economic security, including critical minerals.

In February, U.S. President Donald Trump launched "Project Vault", a $12 billion strategic minerals stockpile initiative backed largely by the U.S. Export-Import Bank.

The administration has also taken equity stakes in mining firms including MP Materials MP.N, USA Rare Earth USAR.O and Korea Zinc 010130.KS.

Investors say U.S. government equity offers more than capital, giving companies access to defence-linked contracts, subsidies and policy backing, and helping protect them from price cyclicality.

Still, caution remains.

"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 law firm Haynes Boone.

"As long as you can gain access to the mines and the resources, I don't see why they can't break China's chokehold over it," Werner said, "but it'll take time and money."
