Court ruling backs Perpetua’s $1.3B Stibnite build

A federal court in the United States has upheld key approvals for Perpetua Resources' $1.3 billion Stibnite gold-antimony project in Idaho, allowing early construction to begin. The court dismissed environmental challenges under several federal laws, confirming that the $1.3-billion project would not jeopardize protected species.

National Bank of Canada analyst Rabi Nizami stated that the ruling was a significant de-risking event and anticipated construction to proceed as planned. The project, which has an annual gold potential of over 400,000 gold-equivalent ounces and an annual earnings potential of $1 billion to $2 billion, is crucial for the U.S. military due to its antimony content in weapons production.

Perpetua is advancing towards a final investment decision expected this year, with first gold production anticipated in 2029. The company received a $2.9 billion loan from the U.S. Export-Import Bank in May and is also supported by the Department of Defense. National Bank rates Perpetua as "outperform" with a target price of C$55.

Construction activities are already underway, with components for the project's autoclaves being fabricated in Europe and temporary worker housing installed. The company holds a cash reserve of $574 million, with its third-quarter budget totaling $177 million, including funds for detailed engineering, field operations, early construction, and exploration.

The project is part of U.S. efforts to establish a domestic antimony supply chain for defense and industrial uses, with 43.5 million indicated tonnes of gold resources and 99.8 million pounds of antimony resources outside the current reserves.
