Perpetua Resources
Perpetua Resources was formed in 2011 to acquire and revive the historic Stibnite mining district, a site that operated intermittently from the 1920s through the 1990s. In 2018, Paulson & Co. became the company's largest shareholder through a series of recapitalizations, effectively anchoring the venture as the primary asset within its natural-resources portfolio. The structure marks a departure from a passive family office: the vehicle is a publicly traded operating company rather than a pooled fund, with Paulson exercising influence through board seats and a concentrated equity position. The company's sole material asset is the Stibnite Gold-Antimony Project, located roughly 100 miles northeast of Boise. The deposit is uniquely positioned as the only domestic U.S. source of antimony, a metal used in munitions, flame retardants, and defense alloys. In 2022, the U.S. Department of Defense issued a letter of interest for up to $1.8 billion in financing through the Defense Production Act, underscoring the project's national-security importance. The mine plan also targets gold and silver byproducts, though antimony remains the strategic draw. The company reached a key regulatory milestone in September 2024 when the U.S. Forest Service published the Final Environmental Impact Statement, clearing a major path toward a construction decision. Paired with the Defense Production Act framework, the public-company structure allows Perpetua to access both government-linked capital and traditional equity markets. Paulson & Co. is the largest but not sole equity holder; the company attracts mining-focused institutional investors drawn to the scarcity of permitted antimony projects in secure jurisdictions. The team is led by professional mine operators and former government officials rather than family principals, with a board that blends financial and operational expertise. Perpetua's most unusual feature is its intermediation between a single-family investment vehicle and a critical-infrastructure asset of the U.S. government. The Stibnite project's permitting path, defense-financing backstop, and national-security narrative distinguish it from typical mining investments, aligning a large concentrated bet with federal industrial-policy objectives.

Frequently asked questions
Who effectively controls Perpetua Resources?
John Paulson's hedge fund firm, Paulson & Co., is the largest shareholder and controls the company through its equity stake and board representation. The investment is a direct bet on domestic antimony production, a departure from Paulson's broader event-driven and merger-arbitrage heritage.
Why is a single-family-affiliated vehicle pursuing a U.S. defense mineral project?
The Stibnite Gold-Antimony deposit is the only known significant antimony reserve in the United States. Antimony is essential for defense manufacturing and currently sourced almost entirely from China and Russia. The project aligns a concentrated family-office-style investment with a federal push to onshore critical mineral supply chains, attracting up to $1.8 billion in Defense Production Act financing.
Does Perpetua operate other mines or hold other assets?
No. The company is a single-asset entity focused entirely on the Stibnite project in Idaho. It has no producing mines or other material exploration properties, making it a binary bet on permitting and construction outcomes.
How does the Defense Production Act financing mechanism work for this project?
In 2022, the U.S. Department of Defense issued a letter of interest indicating up to $1.8 billion in potential financing. The mechanism is not a grant but a loan or loan guarantee structure, designed to underwrite construction costs. Definitive terms remain under negotiation and depend on final permitting and a positive construction decision.
What is the current permitting status of the Stibnite project?
The project reached a key milestone in September 2024 when the U.S. Forest Service published its Final Environmental Impact Statement and a Draft Record of Decision. A final Record of Decision, which would formally authorize the mine plan, is expected following a standard objection-resolution period.
How is Perpetua Resources structured relative to the Paulson family office?
Perpetua is a publicly traded company on NASDAQ, not a private family-office entity. Paulson & Co. holds a concentrated equity position and exerts control through the board, but the structure allows for co-investment from institutional mining funds and offers liquidity. It functions as a direct equity holding rather than a fund commitment.
What makes Stibnite's antimony deposit strategically important?
Antimony is a critical mineral used in projectiles, night-vision equipment, and flame retardants. The U.S. has no domestic production and relies on imports from adversarial nations. Stibnite is the only large-scale, permitted-track antimony reserve in the country, giving it near-monopoly status as a domestic defense supply chain node.
