Ioneer Ltd launched an institutional placement of approximately US$50.4 million (A$72 million) through the issue of about 400 million new ordinary shares, equal to 15% of its existing share base. The new shares are priced at A$0.18, a 14.3% discount to the last closing price of A$0.21 and a 19.4% discount to the 5‑day VWAP of A$0.22.
Proceeds are earmarked for long lead items and early works, advancing project readiness, environmental and permitting costs, other Rhyolite Ridge project expenses, working capital, obligations under the US$996 million DOE loan and general corporate purposes. Pro forma cash is expected to be about US$68.3 million, including an unaudited US$17.9 million cash balance as of 31 December 2025.
The Rhyolite Ridge lithium‑boron project is described as fully permitted and shovel ready, with a 265.5 Mt ore reserve supporting a 77‑year mine life and average annual production of 20,400 tonnes of lithium carbonate equivalent and 70,700 tonnes of boric acid. Updated project economics show an unlevered NPV8 of US$2.237 billion, unlevered IRR of 18.0% and average annual EBITDA of US$417 million, with all‑in sustaining cash costs indicating bottom‑quartile operating costs.
Ioneer Ltd is raising approximately US$50 million (about A$72 million) through a single‑tranche share placement to institutional, professional and sophisticated investors.

Management highlights strong investor support and views the raise as reinforcing confidence in the project’s strategic importance.
The new shares will rank equally with existing ordinary shares. The placement is being led by Bell Potter Securities and Canaccord Genuity (Australia), with settlement and trading of the new shares expected in early February 2026, subject to ASX confirmation.
