DOE closes $996 million loan guarantee for Rhyolite Ridge lithium processing
Summary
On 17 January 2025 DOE closed an ATVM loan guarantee of $996 million ($968 million principal and $28 million capitalized interest) to Ioneer Rhyolite Ridge LLC for on-site lithium carbonate processing at the Rhyolite Ridge project in Nevada. The guarantee is a signed financing facility, not a disbursement, and DOE financing is restricted to the processing plant and related infrastructure, not the open-pit mine. As of June 2026 the issuer remained pre-final-investment decision with equity partner and additional financing requirements, with no substantiated DOE advance.
Analytical significance
Shows a binding U.S. industrial-finance commitment that remains short of funded physical implementation. Separate the closed loan guarantee from the older conditional loan proposal, third-party equity, cash advances, and future mine/processing construction. The U.S. borrower is distinct from the Australian public parent.

DOE/EIS-0565 — Rhyolite Ridge mine processing loan scope
Primary sourceU.S. Department of Energy, NEPA
DOE environmental summary explicitly confines contemplated federal loan to on-site lithium processing facilities, sulfuric acid plant and supporting infrastructure, NOT open-pit mine development/operation. The early NEPA synopsis calls the proposed borrower Rhyolite Ridge Holdings LLC; do not conflate that with the closing release's Ioneer Rhyolite Ridge LLC without legal proof.

Primary sourceIoneer Ltd / U.S. Securities and Exchange Commission (EDGAR)
Issuer securities filing recounts 2025 loan closing and conditions to first DOE advance (strategic partner equity, additional funding and project-finance model), and states that a final investment decision and construction need further financing. The February 2025 Sibanye proposal did not proceed; it is not a valid assumption of equity capital.
