Perpetua Resources

Perpetua Resources is a United States-based mining company focused on the development of critical mineral projects, with particular emphasis on antimony and gold. The company is headquartered in Boise, Idaho, and is primarily known for its flagship Stibnite Gold Project located in Valley County, Idaho. Perpetua Resources positions itself as a domestic supplier of antimony, a mineral classified as critical by the US government due to its strategic importance in defence, renewable energy and industrial applications. The Stibnite project is designed to be one of the only significant sources of mined antimony in the United States, addressing supply chain vulnerabilities as the country currently relies heavily on imports, particularly from China. In addition to antimony, the project is expected to produce gold and silver as co-products. The company has received support from the US Department of Energy and other federal agencies as part of efforts to secure domestic critical mineral supply chains. Perpetua Resources is listed on the Nasdaq stock exchange under the ticker symbol PPTA and on the Toronto Stock Exchange under PPTA. The company has emphasised environmental restoration as part of its development plan, aiming to remediate legacy mining impacts at the Stibnite site while extracting resources. Perpetua Resources was formerly known as Midas Gold Corp before rebranding to reflect its broader critical minerals focus.

Perpetua secures $2.9-billion Exim loan to fully fund Stibnite gold/antimony project

Nasdaq-listed Perpetua Resources has secured a $2.9-billion senior secured loan from the US Export-Import Bank that, combined with cash on hand, will fully fund construction of the Stibnite gold project in Idaho, which has a total project cost of $2.5-billion. The 13-year facility, structured under the Make More in America initiative, comprises a $2.4-billion upfront loan with the remainder covering capitalised interest and fees, and is expected to close in the second half of the year following completion of definitive documentation.

Stibnite to supply US's only domestic antimony reserve

The project is designed to redevelop the abandoned Stibnite Mining District to produce gold and the nation's only reported antimony reserve, a critical mineral used in defence, flame retardants and manufacturing. Perpetua expects the mine to supply an estimated 35% of US antimony demand in its first six years of operation and create about 950 direct jobs during construction and 550 during operations.
