Perpetua Resources (PPTA) advances $2B EXIM Bank review for Stibnite

Rhea-AI Filing Summary

Perpetua Resources Corp. reported that it has received a preliminary, non-binding indicative financing term sheet from the Export-Import Bank of the United States in connection with its application for $2 billion in debt financing for the Stibnite Gold Project. The term sheet is part of a Preliminary Project Letter that also summarizes the bank’s initial due diligence findings on the project.

The company is working with the bank to advance the project through further due diligence and the loan application process and is anticipating final Board consideration by the spring of 2026. Perpetua cautions that the Letter of Interest, Preliminary Project Letter and indicative term sheet are conditional and do not represent a financing commitment, and any funding would depend on successful completion of due diligence, approval of the application, and satisfaction of future conditions and covenants.

Perpetua advances U.S. export credit review for $2B project financing, but all terms remain preliminary and non-binding.

Perpetua Resources now has a preliminary, non-binding indicative term sheet from the Export-Import Bank of the United States tied to its application for $2 billion in debt financing for the Stibnite Gold Project. This step, delivered via a Preliminary Project Letter, indicates that initial due diligence has progressed to a point where potential financing parameters can be outlined.

The company states it is continuing to work with the bank through the next stages of due diligence and the loan application process, with anticipated final Board consideration by the spring of 2026. However, the disclosure emphasizes that the Letter of Interest, Preliminary Project Letter and term sheet do not constitute a commitment, that approved financing may be for less than the amounts referenced, and that even an approved facility would require satisfaction of conditions and covenants before any funding is released.

From an investment perspective, this development highlights regulatory and financing path dependence for the Stibnite Gold Project. The outcome, timing and size of any eventual financing are uncertain, and the company underscores forward-looking risks, pointing investors to U.S. and Canadian securities filings for a fuller description of uncertainties around the review process, timing and potential results of the U.S. financing application.

Cautionary Statement

Investors should be aware that the U.S. EXIM Letter of Interest (“LOI”), PPL and indicative term sheet are non-binding and conditional, and do not represent a financing commitment. A funding commitment, if any, is conditional upon successfully completing the due diligence and underwriting process, which may not be completed on the expected timeline, or at all. If the Company’s application is approved, there can be no assurance that the U.S. EXIM financing will be for the full amount indicated in the LOI or the increased amount requested in the application, or that the approved U.S. EXIM financing will be sufficient for the Company to commence construction of the Project. Further, release of funding under any such commitment would be subject to the satisfaction of certain conditions and covenants by the Company.
