How IRIS Metals plans to break the U.S. import reliance on critical minerals

When investors think of critical minerals, I’m sure that lithium and copper come to mind first and foremost ⁠– after all, they’ve been some of the more buzzy metals across the ASX and in global trade through the 2020s. And yet, highly specialised elements like rubidium, which is vital for GPS systems, atomic clocks, and night vision equipment, remain entirely under the control of foreign suppliers.

This leaves the North American supply chain for advanced technology and national defence facing a quiet but critical vulnerability: A near-total reliance on foreign monopolies for specialised minerals right when they need them most.

While traditional exploration remains bogged down in lengthy, capital-intensive permitting cycles, the urgency to onshore these assets has never been higher.

It’s against this backdrop that IRIS Metals (ASX:IR1) is shifting strategy. Operating in the U.S. west, IRIS has been evolving from a localised lithium explorer into a broader, multi-commodity critmins platform. It has focus, it has a unique rubidium opportunity, and it has the path to near-term production and revenue.

Disrupting the foreign monopoly

The U.S. government has placed an explicit focus on securing domestic supply chains for commodities critical to defence, energy storage, and advanced technologies. Right now, the North American supply chain for highly specialised minerals remains quite vulnerable. As things squeeze tighter, the U.S. is frequently strong-armed by imports from foreign jurisdictions, especially China.

IRIS Metals has built its value-prop on addressing this macro vulnerability. The company is building a portfolio of strategic assets for rapid advancement, combining lithium, rubidium, and tungsten exposure to diversify across high-interest critmins themes while staying entwined in U.S. supply chain initiatives.

This approach directly targets the broader U.S. critical minerals platform, establishing a footprint tied to defence and energy security supply chains.

A unique rubidium opportunity

But, to leave a major footprint, you need a big boot ⁠– and IRIS has just that with its flagship Beecher Project. Beecher sits in the Black Hills of South Dakota, U.S. and represents an advanced exploration and resource growth asset. IRIS has confirmed it hosts both lithium and rubidium mineralisation within the same pegmatite system.

The huge rubidium potential at Beecher is the key. IRIS’s most recent Beecher update includes what management believes is “the only mineral resource estimate in the U.S to include rubidium.” Rubidium is a fairly restricted market, but it’s required for GPS systems, atomic clocks, night vision equipment, and defence-related tech. The U.S. absolutely wants all of those made onshore.

“We perhaps have one of the better grade deposits out there for rubidium, certainly within the States,” IRIS’s President for U.S. Operations, Mart Hartmann, told HotCopper.

“While the market is not huge, the market’s highly specialised, and that demand is constantly there. We think that being the only resource that’s inclusive of rubidium in the States is going to be a huge differentiation for us as… and perhaps provide us with a highly-marketable material in the very near-term.”

The rare path to “very near-term” production, revenue

Beecher is well on its way, too. While some of their peers in the States are tied to far-off production horizons that will still require lots of capital and plenty of infrastructure deployment, IRIS is actively executing a strategy.

The company’s operational runway is helped by Beecher already having an existing mine permit ⁠– a rare regulatory pathway toward rapidly restarting work.

On top of that, IRIS has already demonstrated its on-demand ability to produce crushed direct shipping ore material from the asset, completing test mining and mobile crushing operations at site in 2025. The team successfully mined and crushed approximately 40 tonnes of spodumene-mineralised pegmatite.

From this, 15 tonnes were packaged for metallurgical testing, while the remaining crushed material was stockpiled directly on-site as a DSO pile.

“We demonstrated here last July that we could go mine and crush material and provide direct shipping lithium ore to the market immediately,” Mr Hartmann explained. “We have the ability to restart mining operations at our discretion, if commercially justified.”

Moving forward along the timeline to production, IRIS Metals management is also actively engaged in commercial discussions around possible direct shipping ore contracts and future offtake agreements. Securing a contract could provide the company with early cash flow and a self-sustaining funding mechanism, validating its development thesis far ahead of the typical junior mining timeline.

Not just Beecher under the belt either

To complement the lithium and rubidium assets at Beecher, IRIS has expanded its footprint through a farm-in agreement over the Finley Basin tungsten project. The agreement, executed in March, secured the right to earn up to 100% in the Montana project.

This project aligns with the company’s broader strategy of identifying and advancing clear development potential and existing advantages.

“We’re very focused on overlooked assets,” Mr Hartmann explained. “This opportunity came to us late last year. It was an underappreciated high-grade asset… and we had the opportunity to pick it up on what we think are very favourable terms.”

Best of all, he said, is that Finley Basin “fits with the strategy” IRIS has been building. The basin has clear upside and structural value, largely thanks to its drill-ready setup, as well as its historical high-grade tungsten mineral resource, which was previously defined by industrial operator Union Carbide. “We’re going to bring this project forward relatively quickly,” Mr Hartmann added, pointing to late CY26.

A prior exploration permit is being reactivated, and nearby contract processing infrastructure creates potential near-term development advantages.

What to watch next with IRIS Metals

IRIS has a busy six to twelve months ahead, packed with clear, high-impact milestones. The first thing to watch is the reaction to Beecher’s updated Mineral Resource Estimate before the team pushes forward with discussions on potential direct shipping ore (DSO) contracts.

Should those offtake agreements be locked in, IRIS has earned itself a catalyst that could fast-track a near-term production and revenue scenario at Beecher.

Alongside that, the company will run early staging at Finley Basin. A drill program is up next, to run through the North American summer months, July and August. That campaign, HotCopper understands, is designed to verify, expand, and advance the historical high-grade tungsten reserve into a modern, JORC-compliant resource.

And while drills turn at Findlay, the leadership team – helmed by Mr Hartmann – won’t just be sitting on their hands. Operationally, the focus remains firmly on executing a pragmatic, fast-tracked strategy rather than getting bogged down in endless exploration loops. That means investors can expect steady news flow, even as IRIS looks for other overlooked, permitted, or infrastructure-rich critical mineral assets across the United States to bolt onto its growing exploration platform.

“We’ve got a lot of different things going at the same time. I’ve got a great team that backs me up, and makes sure we act on all these in a very timely basis,” IRIS Metals’ exploration chief concluded while speaking to HotCopper.

By tackling U.S. import problems head-on, IRIS Metals is looking less like a standard explorer and more like a company on the edge of production ⁠— the whole team is “really excited to see the results of their hard work over the next months.”

Bank on it: “We’ll be sitting in a really excellent position six months from now.”
