Rhyolite Ridge Q2 Newsletter – May 2026

The Rhyolite Ridge Lithium-Boron Project continues to advance toward construction along a clear and well-defined path. As the only U.S. development that is fully permitted, construction-ready, and able to mine and refine two critical minerals, Rhyolite Ridge remains central to re-shoring domestic manufacturing and strengthening critical mineral supply chains.

In this edition, we share an update on the strategic partnering process now underway and the steps being taken to maintain construction readiness. We also explore how the Project is strengthening its optionality across lithium and boron—evaluating battery-grade lithium carbonate and defense-grade boron ceramics that connect directly to energy, technology, and national security supply chains. We also provide an update on our Tiehm's buckwheat conservation work, and recognize our 2026 Ioneer Sustainable World Scholars.

Rhyolite Ridge Q1 Newsletter - February 2026

The Rhyolite Ridge Lithium-Boron Project continues to advance towards construction, and our path forward is well defined. Rhyolite Ridge is key to re-shoring U.S. manufacturing and is the only development in the U.S. that is permitted, construction ready, and able to mine and refine two critical minerals.

In this edition of our newsletter, we provide an update on our recent equity capital raise and the proactive steps underway to ensure construction readiness, including procurement of long-lead items and site preparations. We also examine the expanding role of stationary battery storage and infrastructure resilience, which are broadening the demand landscape for U.S. battery materials beyond electric vehicles, and explore the accelerating national momentum to strengthen domestic critical mineral supply chains — with policies increasingly aligned to support projects like Rhyolite Ridge.
