Ivanhoe Electric Gets Preliminary U.S. EXIM Support for $1.1 Billion Arizona Copper Financing

Ivanhoe Electric has received a Preliminary Project Letter from the Export-Import Bank of the United States indicating up to $1.1 billion in potential debt financing for the Santa Cruz Copper Project in Arizona, increasing the amount under consideration from the $825 million outlined by EXIM in April 2025.

The letter marks completion of EXIM’s preliminary due diligence, according to Ivanhoe Electric, but it is not a financing commitment. The company said any loan remains subject to the agency’s remaining review and approval process, with final consideration by the EXIM Board anticipated in spring 2027.

The potential financing would support development of Santa Cruz, an advanced-stage underground copper project on private land near Casa Grande. Ivanhoe Electric plans to produce refined copper cathode at the site without a conventional smelting step, and it expects an updated preliminary feasibility study in September 2026.

A larger EXIM indication, but no final loan yet

The latest step builds on an April 2025 Letter of Interest in which Ivanhoe Electric said EXIM had indicated potential debt financing of up to $825 million with a 15-year repayment tenor. The new $1.1 billion figure is $275 million higher. Ivanhoe Electric’s August 24 announcement did not specify whether the 15-year tenor described in the earlier letter would apply to any final facility.

What has changed is the stage of EXIM’s review. Ivanhoe Electric said the Preliminary Project Letter reflects completion of preliminary due diligence and moves the application forward from the earlier indication of interest. What has not changed is the conditional nature of the funding. The company explicitly said the letter does not constitute a commitment to lend.

That distinction matters because several material terms are still unresolved publicly. Ivanhoe Electric did not disclose an interest rate, security package, draw schedule or final maturity for the proposed $1.1 billion facility. It also did not say that all of the amount would necessarily be authorized or drawn if the application ultimately receives approval.

Ivanhoe Electric applied through EXIM’s Make More in America Initiative, which makes the agency’s medium- and long-term financing tools available to qualifying export-oriented domestic projects. EXIM says all domestic finance awards under the program require Board approval, and domestic financings above $50 million are subject to congressional notification. The agency also applies its standard due diligence and reasonable-assurance-of-repayment requirements.

September study will update the project’s financing case

The size of the potential EXIM support is notable against the capital estimate in Ivanhoe Electric’s June 2025 preliminary feasibility study. That study put initial capital at $1.24 billion and outlined a 23-year mine life based on 136 million tonnes of probable mineral reserves grading 1.08% copper, containing about 1.5 million tonnes of copper.

The 2025 study also projected production of about 1.4 million tonnes of copper cathode over the mine life. Its process design used heap leaching followed by solvent extraction and electrowinning, allowing the project to produce copper cathode on site rather than shipping concentrate to a smelter. Ivanhoe Electric described average annual copper cathode output of about 72,000 tonnes during the first 15 years of mining. Those figures remain study estimates, not operating results.

Some development assumptions have already changed since that study was published. In May 2026, Ivanhoe Electric said it planned to use a Robbins Crossover XRE tunnel boring machine and associated material-handling system for underground access. At that time, it said major surface infrastructure construction was scheduled from the third quarter of 2027 through 2028, with first copper cathode production anticipated in the second quarter of 2029.

The September 2026 update is expected to incorporate that tunnel-boring plan along with engineering and development work completed since the 2025 study. The new study therefore matters to the financing process because it may update capital requirements, construction sequencing and the schedule against which lenders would assess the project. Ivanhoe Electric has not said that the $1.24 billion initial-capital estimate will remain unchanged.

EXIM support would add to bridge financing and existing cash

Ivanhoe Electric has already arranged shorter-term capital while pursuing long-term project financing. In December 2025, the company closed a $200 million senior secured, multi-draw bridge facility with a two-year maturity. Management said the facility was intended to strengthen near-term liquidity during project financing discussions and help fund the start of major construction activities.

That bridge loan is separate from the proposed EXIM financing. Ivanhoe Electric has also said it is considering other sources of project capital, including commercial banks and potential minority investors at the asset level. The company described its EXIM application as being in the advanced stages in May, while continuing discussions with commercial lenders and possible non-debt funding sources.

Ivanhoe Electric reported $256.9 million of cash and cash equivalents at June 30, 2026, up from $173.3 million at the end of 2025. That cash position and the bridge facility provide funding flexibility, but the scale of Santa Cruz’s development plan means the long-term capital structure remains a central issue for the project.

The next concrete project milestone is the updated preliminary feasibility study expected in September. For the proposed EXIM debt, the more consequential decision comes later: Ivanhoe Electric currently expects final Board consideration in spring 2027. Until that approval process is completed and final terms are agreed, the $1.1 billion should be treated as potential financing rather than committed capital.
