8-K: Perpetua Resources Secures $400 Million in Equity Financing to Propel Stibnite Gold Project, Targets $2 Billion EXIM Debt

Perpetua Resources Corp. announced a US$300 million underwritten equity offering and a US$100 million concurrent private placement with Paulson & Co. Inc., forming a key part of its comprehensive financing strategy for the Stibnite Gold Project, alongside a pending US$2 billion EXIM debt application.

Summary

• Perpetua Resources Corp. has entered into an agreement for an underwritten equity offering of 22,728,000 common shares at a price of US$13.20 per share, aiming for aggregate gross proceeds of approximately US$300 million.
• The company has granted the underwriters an option to purchase up to an additional 3,409,200 common shares, representing up to 15% of the offering, which if fully exercised, would bring the total gross proceeds to approximately US$345 million.
• Paulson & Co. Inc., the company's largest shareholder, has agreed to purchase US$100 million of common shares in a concurrent private placement at the same offering price, exercising its pro rata participation right.
• The combined proceeds from the offering and private placement, along with anticipated EXIM debt financing and royalty financing, are intended to fund the Stibnite Gold Project's construction costs, estimated at approximately US$2.2 billion, plus additional funds for a cost-overrun account, debt service, working capital, and exploration activities.
• Perpetua submitted a formal application to the Export-Import Bank of the United States (EXIM) in May 2025 for potential debt financing of up to US$2.0 billion, an increase from the initial US$1.8 billion Letter of Interest (LOI) received in April 2024, reflecting increased estimated job-years and engineering work.
• EXIM's due diligence on the application is ongoing, with the company anticipating closing the debt financing in 2026, conditional upon successful completion of the due diligence and underwriting process.
• The company is in advanced discussions with potential partners for a royalty or stream financing arrangement targeting proceeds between US$200 million to US$250 million, along with a US$155 million guarantee for reclamation bonds, expected to be formalized in summer 2025.
• The US$155 million guarantee is anticipated to be sufficient to satisfy construction phase financial assurance requirements, which is expected to position the company to receive the USFS notice to proceed and commence construction later in 2025.
• Most major state permits have been received, with the remaining principal state permitting programs and one state permit modification expected to be issued by relevant agencies in summer 2025.

Sentiment

Score: 8

Explanation: The announcement of a significant equity raise, coupled with the formal application for substantial EXIM debt financing and progress on permits and royalty financing, indicates strong momentum towards fully funding and commencing the Stibnite Gold Project. While inherent risks of a large-scale mining project and reliance on future financing remain, the comprehensive financing strategy and strategic importance of the project are highly positive developments.

Positives

• Successfully secured significant equity financing of US$400 million (US$300 million public offering + US$100 million private placement), providing substantial capital for project development.
• Paulson & Co. Inc., the largest shareholder, demonstrated continued strong support by participating in the private placement for US$100 million.
• Formal application for up to US$2.0 billion in EXIM debt financing has been submitted, an increase from the initial LOI, indicating progress and potential for substantial government support for the project.
• Advanced discussions for royalty/stream financing and a US$155 million guarantee for reclamation bonds are underway, which are crucial steps for satisfying financial assurance requirements and enabling project commencement.
• Anticipated receipt of remaining state permits and the USFS notice to proceed in summer 2025, paving the way for construction later in 2025.
• The Stibnite Gold Project is positioned as a domestic source of antimony, a critical mineral for U.S. defense needs, aligning with national strategic priorities for critical resource independence.

Negatives

• The EXIM Letter of Interest is non-binding and conditional, and there is no assurance that the company will receive the full requested amount or that the financing will be sufficient.
• The royalty/stream and guarantee agreement is not yet definitive, and there is no assurance it will be finalized on anticipated terms or be sufficient to meet all financial assurance requirements.
• Paulson & Co. Inc. holds significant influence (34.6% pre-offering, at least 30% post-offering), which could impact corporate decisions, delay or deter changes of control, and affect market liquidity.
• The company does not currently have sufficient committed financing to commence construction of the Project, relying on the successful completion of future EXIM and royalty financing.
• The Stibnite Gold Project has no history of commercial production, and there are inherent risks associated with establishing new mining operations, including unexpected costs, problems, and delays.

Risks

• Paulson & Co. Inc.'s significant influence (34.6% pre-offering, at least 30% post-offering) may delay or deter a change of control, deprive shareholders of a premium, and affect the market price and liquidity of the common shares.
• The company does not currently have sufficient funds or committed financing necessary to commence construction of the Project (estimated at approximately US$2.215 billion as of December 31, 2024), and there is no assurance of obtaining necessary funds on acceptable terms, or at all.
• Financing, if obtained, may subject the company to restrictive covenants, significant debt service costs, or dilution to existing shareholders.
• The issuance of a final financing commitment from EXIM is subject to EXIM's underwriting criteria, authorization process, and satisfaction of terms and conditions, and the amount and timing of such funding, if any, is uncertain and subject to conditions outside the company's control.
• The proposed royalty/stream and financial assurance arrangement is not yet definitive, and there can be no assurance that the company will realize the expected benefits, including satisfying financial assurance requirements on anticipated timelines.
• The company is in discussions with other government agencies for additional debt facilities to fund cost overruns, but there is no assurance such discussions will result in financing commitments.
• Delays or a failure to obtain remaining state and local permits, or successful legal challenges to existing permits, could have a material adverse impact on the company's ability to commence construction and operations.
• The company has no history of commercially producing precious metals from its mineral properties, and there can be no assurance that it will successfully establish mining operations or profitably produce precious metals.
• New mining operations commonly experience unexpected costs, problems, and delays during development, construction, and mine start-up, and a significant drop in commodity prices could render the Project uneconomic.
• The company's operations and permits are currently and may in the future be subject to legal challenges (e.g., February 2025 lawsuit against USFS, putative federal class action lawsuit), which could result in increased defense costs, delays, or adverse impacts.
• The company may be subject to liability and remediation responsibilities for impacts from legacy mining operations under CERCLA and existing consent decrees.
• A shortage of supplies and equipment, or the inability to obtain them when needed and at expected prices, could adversely affect the company's ability to operate its business.
• General economic conditions, including volatility in commodity prices, tightening credit markets, inflation, and trade tariffs, may adversely affect the mining industry, the company's growth, future profitability, and ability to obtain sufficient financing.
• Proposed changes in U.S. tax law, such as a bill passed by the House of Representatives on May 22, 2025, may have adverse tax consequences for certain non-U.S. holders of common shares, potentially increasing withholding taxes on dividends.
• Changes in U.S. administrative policy, including the imposition or increase of tariffs on steel (e.g., 25% on March 12, 2025, raised to 50% on June 5, 2025) and other raw materials, could increase costs and impact trade relations.

Future Outlook

The company anticipates closing the EXIM debt financing in 2026 and expects the proposed royalty and financial assurance arrangement to be formalized in summer 2025. Remaining state permits are also expected in summer 2025, positioning the company to receive the USFS notice to proceed and commence construction of the Stibnite Gold Project later in 2025. The combined financing package is believed to provide sufficient capital for the Project's construction costs, cost-overrun account, debt service, working capital, and exploration activities.

Management Comments

• The Company intends to use the proceeds of the Offering and the Private Placement as part of a comprehensive financing package for the development of the Company’s Stibnite Gold Project.
• Together with the EXIM debt financing and royalty financing described below, if successfully completed in the amounts anticipated, the Company believes that the net proceeds from the Offering and the Private Placement will provide the Company with sufficient capital to fund the Project construction costs of US$2.2 billion, along with additional funds for a cost-over run account, debt service, working capital costs in excess of the Project capital costs and exploration activities.
• Securing the financial assurance in this amount is expected to position the Company to receive the USFS notice to proceed under the approved plan of operation and satisfy the financial assurance conditions of various federal and state permits, allowing the Company commence construction later in 2025.
• Based on indications from the relevant agencies, the Company expects the remaining state permits required to commence construction to be issued by the relevant agencies in summer 2025.
• The Company believes that the claim [putative federal class action lawsuit] is without merit and intends to vigorously defend itself.

Industry Context

The Stibnite Gold Project is highlighted as one of the highest-grade, open-pit gold deposits in the United States and is designed to be the only mined source of antimony in the U.S., a critical mineral essential for national defense needs (e.g., small arms, munitions, missile types). This aligns with broader U.S. strategic initiatives to secure domestic supply chains for critical minerals and reduce reliance on foreign sources. The project also emphasizes responsible mining practices and site restoration of an abandoned mine, addressing environmental concerns often associated with historical mining operations.

Legal Proceedings

• On February 18, 2025, claims were filed in the U.S. District Court for the District of Idaho against the USFS and other federal agencies by claimants alleging violations of NEPA and other federal laws in the regulatory process for the Project, seeking to vacate key governmental permits and enjoin further implementation. Perpetua Resources has intervened in this lawsuit.
• In February 2025, a putative federal class action lawsuit was filed in the United States District Court for the District of Idaho against the Company and certain of its current officers and directors, on behalf of a proposed class of purchasers of the Company's common shares during the period from April 17, 2024, to February 13, 2025. The Company believes the claim is without merit and intends to vigorously defend itself.
• The Company is currently party to an Administrative Settlement and Order on Consent issued under CERCLA requiring the Company to undertake response actions with respect to impacts from legacy mining operations.
• The Company is subject to certain restrictions on the use of the Project mine site under certain consent decrees previously entered into by third parties and governmental authorities.

Related Party Transactions

• Paulson & Co. Inc., the largest shareholder, agreed to purchase US$100 million of common shares in a concurrent private placement at the Offering Price, exercising its pro rata participation right pursuant to the Investor Rights Agreement.

Stakeholder Impact

• **Shareholders**: Potential dilution from the equity offering, but also significant progress towards fully funding the Stibnite Gold Project, which could enhance long-term value. Paulson's substantial ownership (at least 30%) grants it significant influence over corporate decisions and may affect share liquidity.
• **Employees**: The increased EXIM application amount reflects an increase in estimated job-years, indicating potential for significant job creation related to the Project's development and operation.
• **Customers/Nation**: The Stibnite Gold Project is positioned to become the only mined source of antimony in the United States, a critical mineral for national defense, thereby enhancing domestic supply chain security and reducing reliance on foreign sources.
• **Creditors**: The company is seeking substantial debt financing (up to US$2.0 billion from EXIM) and royalty financing, which will significantly increase its financial leverage but is intended to fund a major capital project.
• **Local Communities/Environment**: The project involves site restoration of an abandoned mine and is subject to extensive permitting and financial assurance requirements under federal and state law, aiming to mitigate environmental impacts and ensure reclamation.

Next Steps

• Closing of the underwritten equity offering on or about June 16, 2025.
• Underwriters have 30 days from the closing of the Offering to exercise the over-allotment option.
• Ongoing EXIM due diligence and underwriting process, with anticipated closing of debt financing in 2026.
• Formalization of the proposed royalty and financial assurance arrangement in summer 2025.
• Issuance of remaining state permits required to commence construction in summer 2025.
• Receipt of the USFS notice to proceed under the approved plan of operation.
• Commencement of construction of the Stibnite Gold Project later in 2025.
• Continued discussions with other government agencies regarding the possibility of securing additional debt facilities to fund any cost overruns.
• Vigorously defending against the putative federal class action lawsuit.
