A small-cap ASX miner is turning heads on Friday after releasing an update that has gone down well with the market.
At the time of writing, the Ioneer Ltd (ASX: INR) share price is up 7.14% to 15 cents.
Despite the gain, it has been a rollercoaster ride for shareholders. The stock is still down around 19% in 2026, but it has jumped 54% over the past 12 months.
The latest release seems to have hit the right note, with critical minerals still a major focus in the US.
Here's what Ioneer announced.

Ioneer lands US Army-linked award
In a statement to the ASX, Ioneer said it received a conditional US Army award for land at Utah's Toole Army Depot.
The company said the long-term lease would support the development of a critical mineral processing facility.
Fortunately, Ioneer was one of four companies selected, alongside Empire State Mines, EnergyX and REalloys.
The US Army is looking to use parts of its land to help build more domestic processing capacity for critical minerals. These include lithium, boron, graphite and rare earths, which are used across defence, energy and advanced manufacturing supply chains.
Ioneer said the award is tied to its Rhyolite Ridge Lithium-Boron Project in Nevada.
The company describes Rhyolite Ridge as the largest undeveloped boron ore reserve in the world outside Turkey. It also said the project is the only known lithium-boron deposit in North America.
Why this is a big deal
The land lease is useful, but this update is really about the bigger opportunity around Ioneer.
The US is trying to build more mineral processing capacity at home, especially for materials used in defence, energy and advanced manufacturing.
And this is where Rhyolite Ridge stands out.
It's not just another lithium project. It has a large boron resource, which gives Ioneer another way into America's supply chain push.
Boron doesn't get mentioned as much as lithium. However, Ioneer said it is used in military armour, high-strength magnets, semiconductors and nuclear applications.
The company also noted that the US government added boron to its list of critical minerals in November 2025.
The US Army release said "The ability to process critical minerals on U.S. soil is a national-defence priority required for munitions, missiles, sensors, batteries, and the platforms our soldiers depend on."
What investors will be watching now
While today's update is a positive one, there is still plenty of work ahead.
Keep in mind that the lease award is conditional, and Ioneer still needs to keep moving Rhyolite Ridge toward development.
This means attention turns to progress on funding, approvals, construction plans and a final investment decision (FID).
Fortunately, there has been some progress on that front.
Recent reports have pointed to support from South Korean groups Hyundai Engineering and Korea Overseas Infrastructure & Urban Development for the project.
