U.S Government offers conditional commitment for a loan of up to US$700 million for the Rhyolite Ridge lithium-boron project

Salient features:

• The Proposed Loan is for an amount up to US$700 million
• The conditional commitment follows extensive engagement and demonstrates the DOE’s strong support for and confidence in Rhyolite Ridge and its technical fundamentals and confirms the expected economics of Rhyolite Ridge
• If completed, the Proposed 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 Proposed Loan and Sibanye-Stillwater’s expected equity contribution to secure its 50% stake in Rhyolite Ridge (once all conditions precedent* for completion of the joint venture have been fulfilled or waived, as applicable), are anticipated to fund a substantial part of the preliminary project capital.

The Proposed Loan remains subject to negotiation and documentation of long-form agreements and various conditions and may be revised to match updated project economics leading up to financial close following achievement of certain conditions.

Sibanye-Stillwater Chief Executive Officer, Neal Froneman commented; “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 U.S. mining operational and project development expertise, hydrometallurgical expertise and deep relationships with automakers and automotive OEMs globally.”

“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. Rhyolite Ridge is a high-quality lithium project that is ideally positioned to supply locally mined and beneficiated metals to support the U.S. battery ecosystem. The Proposed Loan represents a significant step towards further de-risking funding and ultimately progressing Rhyolite Ridge to production. If finalised, this loan will ensure that the project can be swiftly advanced once the necessary permits have been granted and the outstanding conditions fulfilled. This is a significant milestone in the development of Rhyolite Ridge, which promises to positively contribute to reducing climate change”, Froneman concluded.
