Perpetua Resources has received a $2.9bn senior secured long-term loan from the Export-Import Bank of the US (EXIM) to develop the Stibnite Gold Project in Idaho.
This funding is part of EXIM’s Make More in America Initiative (MMIA), designed to enhance domestic manufacturing and job creation.
The loan approval from EXIM followed comprehensive technical, financial, environmental and social evaluations, along with a 25-day notice period to Congress.
The Stibnite Project is said to be the only identified domestic reserve of antimony, a crucial mineral for national security and industry.
The loan, alongside Perpetua's cash reserves, is expected to cover the project's construction costs.
The project aims to sustainably redevelop the abandoned Stibnite Mining District in Idaho, focusing on gold production and establishing the only reported domestic reserve of antimony.
It involves environmental clean-up, securing antimony for US commercial and defence needs, and creating an average of more than 700 direct jobs annually, contributing significant tax revenue to local communities and Idaho.
The loan includes a $2.4bn upfront facility, with the rest allocated for capitalised interest and EXIM’s exposure fee.
Interest on the loan will align with the long-term US Treasury bond rate, adding 100 basis points, and will be fixed at the initial drawdown. Repayments are expected to begin in 2030.
Perpetua Resources president and CEO Jon Cherry said: “It is time to make more in America and today marks not only a key milestone for Perpetua Resources but a significant step in mineral security for our country.
“When the federal government and private industry work together on a shared national priority, big things are made possible. The $2.9bn loan positions us to bring the Stibnite Gold Project to life and signals a new day in American mineral independence and responsible mining.”
The loan is set to be available in the latter half of 2026, pending completion of final documentation and customary conditions.
Perpetua Resources' engagement with EXIM began in 2024, leading to this approval after thorough evaluation.
Endeavour Financial is acting as the financial advisor for the loan, with Hunton Andrews Kurth providing legal counsel for the company’s transaction.
In October last year, Perpetua secured $255m through equity investments from Agnico Eagle Mines and JPMorganChase, collectively referred to as the private placement.

Four leading AI models discuss this article
"The EXIM loan approval materially advances PPTA's Stibnite project by locking in low-cost, long-term construction capital for antimony and gold production."
Perpetua Resources (PPTA) secures a major de-risking event with the $2.9 billion EXIM loan for its Stibnite Gold Project in Idaho. This funding, part of the Make More in America initiative, covers construction for gold output and the sole US antimony reserve, crucial for national security. Combined with October's $255 million equity raise, it positions the company to begin repayments only in 2030 at favorable Treasury-plus-100bp rates. The project promises over 700 jobs and environmental remediation of an abandoned site. This government backing signals strong federal support for domestic critical minerals supply chains.
Environmental lawsuits and permitting delays have historically plagued similar mining projects in the US, potentially pushing production timelines beyond 2030 or forcing costly redesigns that could strain even this loan structure.
"This is a national security subsidy disguised as project finance—transformative for US antimony independence but operationally risky and dependent on commodity prices the article never specifies."
This is a genuine inflection point for US mineral security, but the article conflates political win with commercial viability. EXIM's $2.9bn commitment signals government commitment to domestic antimony supply—critical for defense electronics and semiconductors. However, the loan structure reveals risk: 100bps over Treasury (likely 5-5.5% all-in) on a project with no revenue until 2028-29, plus repayment starting 2030 assumes flawless execution. Perpetua must still secure $500m+ in equity, navigate environmental permitting, and prove Stibnite can compete with Chinese antimony on cost. The article omits: timeline slippage penalties, commodity price assumptions, and what happens if gold prices collapse or antimony demand disappoints.
EXIM loans to mining are politically motivated, not economically rational—if Stibnite were truly viable, private capital would fund it entirely. The 2030 repayment cliff assumes zero cost overruns on a project in an abandoned mining district with complex environmental remediation.
"The EXIM loan transforms Perpetua from a speculative junior explorer into a government-backed strategic asset, significantly lowering their cost of capital and dilution risk."
This $2.9bn EXIM loan is a massive de-risking event for Perpetua Resources (PPTA). By securing financing at Treasury rates plus 100 bps, they effectively bypass the current high-cost capital markets, which usually punish junior miners with massive equity dilution. The strategic importance of antimony—a critical mineral for defense applications—provides a 'national security' floor that makes this project difficult for regulators to kill. However, investors must watch the 2026 drawdown date; this is not immediate liquidity. The company still faces significant execution risk, environmental permitting hurdles in Idaho, and the volatility of gold prices, which will ultimately dictate the project's internal rate of return (IRR) once production finally commences.
The project relies on the successful remediation of a legacy mining site; any environmental litigation or unforeseen cleanup costs could easily blow through the $2.9bn budget and trigger default clauses before the first ounce of gold is poured.
"The deal accelerates US critical-minerals independence but hinges on favorable prices and flawless execution; missteps could trap Perpetua with unsustainable leverage."
EXIM's $2.9 billion loan to Perpetua Resources for the Stibnite project signals a rare, state-backed bet on domestic critical minerals, potentially accelerating US mineral independence and job creation. Yet the article understates execution risk: the capex, permitting, tailings and environmental liabilities, along with reliance on favorable antimony and gold prices, could erode cash flows. The financing cadence (2.4B upfront, repayment starting 2030) ties a long-lived asset to a fixed-rate debt in a volatile sector, with policy and rate risk under MMIA as wildcards. If prices drop or costs overrun, the leverage could become a headwind rather than a tailwind.
The strongest case against is that project economics are highly price-sensitive and political-backed financing can become a liability if commodity prices or policy priorities shift; delays or overruns could strand the loan.
"Federal-state permitting mismatch could derail the assumed 2026 start and favorable loan terms."
Claude notes the equity gap but misses how EXIM support might secure defense offtakes for antimony, buffering against gold volatility. The real gap in arguments is the potential clash between federal loan milestones and Idaho's state environmental reviews. Any misalignment could push construction past the 2026 drawdown window, requiring amendments that dilute the favorable terms everyone assumes will hold.
"The 2026 drawdown date is more fragile than the panel assumes—state permitting risk could force costly restructuring before construction even starts."
Grok flags the federal-state permitting misalignment—this is the real landmine. But I'd push harder: EXIM's 2026 drawdown assumes Idaho's environmental review concludes by late 2025. State reviews for legacy mining sites routinely take 3-4 years. If Perpetua hits that wall, they either renegotiate (losing favorable terms) or tap equity markets at distressed valuations. Nobody's quantified the probability of timeline slippage or its cost.
"The federal government's political commitment to the environmental remediation aspect of Stibnite acts as an implicit guarantee against project failure."
Claude and Grok are fixated on the permitting timeline, but they are ignoring the 'remediation-as-a-service' model. Stibnite isn't just a mine; it's a massive, taxpayer-funded cleanup of a Superfund-adjacent site. If the project stalls, the federal government faces a political nightmare—admitting they financed a failure that left the site worse off. The political 'sunk cost' ensures they will likely subsidize overruns rather than let the project default, effectively creating a sovereign-backed floor.
"Timelines and permitting risk trump stated yield terms; if drawdown slips beyond 2026, the project risks debt service on a non-producing asset, forcing equity repricing or term renegotiation."
Claude, your focus on the 5-5.5% all-in yield masks a deeper risk: pushouts in Idaho's environmental reviews can push EXIM drawdown far beyond 2026, turning debt service into a burden on a non-producing asset. The article and your math treat favorable terms as a given; they aren’t. If timelines slip, Perpetua may need equity at distressed valuations or renegotiate terms, eroding the supposed 'tier-one' financing moat.
