• Project Financing Secured

  A conditional US$996 million loan from the U.S. Department of Energy (DOE) was finalized in January 2025 to support the Rhyolite Ridge Lithium-Boron Project. The company is actively seeking a strategic equity partner to meet the remaining conditions precedent for loan funding.

• Federal Permit Upheld in Court

  The U.S. District Court upheld the Bureau of Land Management's (BLM) approval of the Rhyolite Ridge mine plan on March 31, 2026. While plaintiffs filed an appeal to the Ninth Circuit on April 9, 2026, this is not expected to delay commencement of construction.

• Recent Equity Capital Raise

  Post-period, ioneer completed an A$72 million (approximately US$50 million) equity raise on February 5, 2026, through a single-tranche placement. Proceeds will accelerate project development, fund readiness, environmental permitting, and working capital.

• Updated Mineral Resources & Reserves

  The October 2025 estimates show a 4.1 Mt increase in total mineral resources to 283.1 Mt and a 5.2 Mt increase in total ore reserves to 265.5 Mt, reflecting improved project economics due to reduced leach retention time and lower acid consumption.

This 20-F filing provides a comprehensive update on ioneer's Rhyolite Ridge Lithium-Boron Project, showcasing substantial progress in de-risking and funding. The finalization of a conditional $996 million DOE loan, coupled with the recent court decision upholding the federal permit, significantly advances the project towards a Final Investment Decision (FID). The post-period $50 million equity raise further strengthens the company's liquidity and ability to fund critical early works. While the project remains in a development stage and requires an equity partner, these milestones, alongside updated and increased mineral resource and reserve estimates, provide a clearer path to commercial production and are highly positive for investor confidence.
