Perpetua Resources Provides Construction Update on the Stibnite Gold Project and Exploration Activities
Perpetua recycles previous drill results from its Idaho gold-antimony project, confirming no new assay data was released.
Perpetua Resources Corp. (PPTA) issued a construction and exploration progress update on August 24, 2026, rather than a fresh assay release. The drill intervals cited in the report are the same ones first published on August 6, 2026.
Key reported intervals include: - Clark Tunnel Fault Zone: 6.4 m of 16.2 g/t gold and 1.7% antimony from surface - Clark Tunnel Fault Zone: 15.0 m of 6.3 g/t gold and 0.8% antimony from 11 m depth - Clark Tunnel Fault Zone: 21.3 m of 3.2 g/t gold and 0.9% tungsten from 24 m depth, described as a new gold-tungsten discovery - Huckleberry Fault Zone: 69.6 m of 0.8 g/t gold - Hangar Flats: 3.0 m of 14.5 g/t gold near surface - Hangar Flats deeper intercepts: 22.9 m of 3.2% antimony and 1.2% tungsten; 9.8 m of 8.3% antimony and 4.6% tungsten; 3.4 m of 10.6% antimony and 1.5% tungsten
Regarding construction, dual autoclaves are currently in fabrication in Europe. Roughly half of the ATCO worker housing units had been delivered by August 24, 2026, and the administrative pad build-out is underway. The Burntlog Route has been identified as the preferred project access.
Other developments include a July 29 ribbon-cutting for a modular antimony pilot plant with the U.S. Army and Idaho National Laboratory. On August 18, 2026, the U.S. District Court affirmed federal approvals, issuing a narrow remand to the U.S. Fish and Wildlife Service regarding Incidental Take Statements. Plaintiffs filed an appeal, but construction continues.
The release reports approximately 5,800 m of a 10,000 m program completed, matching the meterage figure given in the August 6 release, indicating no meaningful new drilling progress is disclosed.
Perpetua Resources Corp. (PPTA) is an advanced developer holding 4.8 moz of gold reserves and 149 Mlbs of antimony reserves. The company secured a $2.9 billion EXIM loan approval and currently carries a market capitalization near $4.4 billion. Near-pit drill results are considered incremental to the existing resource base.
The market previously adjusted to the August 6 drill release, with the stock rising from approximately $26.48 on July 30 to $34.48 on August 7, representing a roughly 30% move. The current price of $34.90 reflects those August 6 intercepts.
The August 31 release contains no new assay intercepts or new meterage, repeating the same highlight holes. While the litigation update is meaningful, it was already reflected in the August 19 price move from $33.08 to $35.69. Construction progress remains favorable but was expected. The release does not materially alter the embedded expectations, nor does it change the resource, reserve, or mine-life thesis on its own.
Perpetua Resources Corp. (PPTA) is advancing the Stibnite Gold Project, a permitted brownfield development asset located in central Idaho that targets gold, antimony, and silver. The project holds gold reserves of 4.8 million ounces and antimony reserves of 149 million pounds. Inferred and measured and indicated resources total 1.6 million ounces and 1.5 million ounces of gold, respectively.
The development plan includes three open pits—Yellow Pine, Hangar Flats, and West End—along with historical tailings. The early production profile calls for 463,000 ounces of gold per year during the first four years. Initial capital requirements are estimated at $2,576 million, with a base case after-tax NPV5 of $3,457 million.
Financing for the project includes a $2.9 billion U.S. EXIM loan, which has been approved pending definitive documentation. As of June 30, 2026, the company held $574.2 million in unrestricted cash. Major shareholders include Paulson & Co., Agnico Eagle, and JPMorgan Chase.
