ioneer Ltd is an Australian company focused on developing the Rhyolite Ridge Lithium‑Boron Project in Nevada, which it owns 100%. The deposit is described as the only known lithium‑boron deposit in North America and is intended to be a long‑life, low‑cost source of lithium and boron.
In October 2024, the project received a federal Record of Decision from the Bureau of Land Management, completing the main U.S. permitting process. In January 2025, ioneer closed a US$996 million U.S. Department of Energy loan with a 20‑year term to help fund an on‑site processing facility, while total project capital expenditure is now estimated at about US$1,667.9 million, more than double a 2020 estimate. The company has invested US$203.1 million to date, is seeking strategic partners after Sibanye‑Stillwater chose not to proceed with a joint venture, and warns it still needs substantial additional funding and faces legal and environmental risks that could delay or affect development.
