Friday, 13 January 2023 – ioneer Ltd (“Ioneer” or the “Company”) (ASX: INR, Nasdaq: IONR) is pleased to announce finalization of a term sheet and offer of a Conditional Commitment1 for a proposed loan of up to US$700 million from the U.S. Department of Energy (DOE) Loan Programs Office for financing the construction of the Rhyolite Ridge Lithium-Boron Project in Nevada, USA.
Under the term sheet, the proposed loan is for an amount up to US$700 million2 with a term of approximately 10 years. The loan will be at an interest rate fixed from the date of each advance for the term of the loan at applicable U.S. Treasury rates.
The proposed loan is to be made under the DOE’s Advanced Technology Vehicles Manufacturing (ATVM) loan program in support of the Biden Administration’s critical minerals strategy. DOE has over US$50.0 billion in remaining loan authority under the ATVM program to support the manufacture of eligible advanced technology vehicles including electric vehicles (EVs), and qualifying components and materials, in the United States. Domestic processing of critical minerals, such as lithium, for use in EV batteries qualifies for the ATVM loan program3.
After commencing pre-application discussions in February 2021 regarding the DOE’s ATVM loan program, Ioneer submitted an application in October 2021. The application was deemed substantially complete in December 2021 which initiated a third-party due diligence process that has been ongoing since March 2022. The Loan Programs Office has undertaken extensive and detailed market, technical and legal due diligence on both Ioneer and the Rhyolite Ridge Project. The Conditional Commitment is based on a revised Plan of Operations submitted by Ioneer to the U.S. Bureau of Land Management (BLM), now in the National Environmental Policy Act (NEPA) process, which completely avoids all direct impact and minimizes indirect impact on Tiehm’s buckwheat.
Rhyolite Ridge is the most advanced undeveloped U.S. lithium project, and it is on track to provide an environmentally sustainable, long-life source of both lithium and boron for delivery into the U.S. domestic EV supply chain.
The term sheet and Conditional Commitment from DOE demonstrates its strong support for the Rhyolite Ridge Project and, if finalized, the loan would be the first-ever by the DOE to provide financing for the processing component of a project where lithium is extracted and refined at site.
The proceeds from the DOE loan, along with Sibanye Stillwater Limited’s (“Sibanye-Stillwater”) expected equity contribution to secure a 50% stake in the Rhyolite Ridge Project once all conditions precedent for the joint venture have been fulfilled or waived, as applicable, are anticipated to fund a substantial part of the preliminary capital expenditure estimate from the revised plan of operations included in the application submitted to the DOE. Finalizing the term sheet and receiving the Conditional Commitment from the DOE represent a significant step towards completing the funding for the Rhyolite Ridge Project.
The proposed loan amount is necessarily based on preliminary and partially complete information that the DOE required from Ioneer pertaining to: 1) capital expenditure for a conceptual mine plan; 2) macroeconomic cost escalation assumptions; and 3) capital expenses to meet DOE stipulated requirements for participation in the ATVM program. As a result, the proposed loan amount remains subject to negotiation and documentation of long-form agreements and various conditions and may be subsequently revised to appropriately match updated project economics leading up to financial close and upon satisfaction of several conditions, including:
• Positive Record of Decision (ROD) issued by the BLM;
• Updated cost estimate including a P85 cost contingency4;
• Updated Resource and Reserve statements and mine plan incorporating the southern extension to the deposit;
• Updated economic model based on the updated information above;
• All necessary permits; and
• Final Investment Decision (FID) by both Ioneer and Sibanye-Stillwater.
Ioneer and Sibanye-Stillwater will continue to progress work on the engineering, complete additional drilling post ROD to delineate the southern limits of the deposit where mining is expected to commence and optimize the mine plan. Based on these outcomes, an updated capital and operating cost estimate will be provided to stakeholders before making an FID.
The final loan is subject to approval of the Ioneer and Sibanye-Stillwater Boards, receipt of all material governmental consents necessary for the loan and the negotiation and execution of binding loan documents. When binding loan documents are signed, certain closing conditions must be satisfied before the loan commitment from DOE becomes effective and funds can be advanced.
Jigar Shah, Director of DOE’s Loans Programs Office commented:
“Rhyolite Ridge is a major step towards bolstering domestic lithium production for clean energy technologies, and LPO is excited to further develop an environmentally responsible U.S. supply chain for critical materials.”
James Calaway, Executive Chairman of Ioneer commented:
“The Conditional Commitment highlights Rhyolite Ridge’s strategic role in strengthening America’s critical mineral supply chain in providing a secure, sustainable, and reliable domestic source of lithium for the growing electric vehicle ecosystem.”
Bernard Rowe, Managing Director of Ioneer commented:
“We are pleased to have finalized the term sheet and received a Conditional Commitment from the DOE for up to a $700mm loan from the ATVM program. The Conditional Commitment is the culmination of 23 months of discussions with and due diligence by the Loan Programs Office and it represents a significant milestone for Rhyolite Ridge. We look forward to working with the DOE and Sibanye-Stillwater to complete the remaining milestones to start construction of Rhyolite Ridge.”
Neal Froneman, Chief Executive Officer of Sibanye-Stillwater commented:
“Rhyolite Ridge is a world-class lithium project which is ideally positioned to provide locally mined and beneficiated metals to further develop the U.S. battery ecosystem. The proposed loan represents a significant step towards further de-risking funding and ultimately progressing Rhyolite Ridge to production. We are encouraged by the DOE’s commitment to the development of the U.S. national battery metals mining industry through supportive funding programs such as the ATVM program and the commitment of the Ioneer team to date, aimed at ensuring that this high-quality project can be swiftly advanced once the necessary permits have been granted and outstanding conditions have been fulfilled. This is a significant milestone in the development of this critical project which promises to positively contribute to reducing climate change.”
“Sibanye-Stillwater’s battery metals strategy is primarily focused on the U.S. and Europe in recognition of the developing need for battery metals for the transition towards greater electrification of their established automotive industries. Sibanye-Stillwater is well placed to be a supportive partner and add significant value to Rhyolite Ridge given its complementary global mining experience and expertise, including its US mining operational and project development expertise, hydrometallurgical expertise and deep relationships with automakers and automotive OEMs globally.”
