Perpetua Resources Corp. reports developments tied to the Stibnite Gold Project, a gold, silver and antimony mineral project in Idaho. Company news centers on mineral exploration and development, updated technical report summaries, project economics, early works activity, engineering and procurement planning, and financing-related disclosures for the project.
Recurring updates also cover antimony as a critical mineral, including pilot processing work with Idaho National Laboratory, as well as operating and financial results, leadership appointments, shareholder voting matters, capital-structure disclosures, material agreements and governance matters.
Perpetua Resources (PPTA) advanced road, housing and powerline construction while expanding exploration drilling at its Stibnite Gold Project.
Crews began pioneer roadwork on Burntlog Route. Civil work at the worker housing site finished in late August, and foundation installation began. Power poles and other equipment were delivered, while substations and transformers were ordered. Drilling surpassed the original 10,000-meter program in August and will continue into fall. Assaying of completed holes has begun. At the Clark Tunnel Fault Zone, five follow-up holes totaling 1,900 meters were completed by the end of August, and scheelite has been observed in subsequent drill core. Mining in exploration areas outside the approved plan would require further environmental review and permits.
Perpetua Resources (Nasdaq/TSX: PPTA) reported ongoing early works and critical-path construction at the Stibnite Gold Project in Idaho. Dual autoclave components are being fabricated in Europe, temporary workforce housing is operating, and about half of the permanent ATCO housing units are on site, with grading and utilities completed for installation.
Key infrastructure, including the Administrative Pad and Burntlog access route, is advancing. Exploration drilling has intensified to four rigs, with roughly 5,800 of 10,000 meters completed and multiple high-grade gold, antimony, and tungsten intercepts at Clark Tunnel Fault Zone, Huckleberry Fault Zone, and Hangar Flats. Perpetua, the U.S. Army, and Idaho National Laboratory opened a modular antimony processing plant to pilot domestic antimony trisulfide production, supported by over $87 million in U.S. government funding since 2022. A recent U.S. District Court ruling largely upheld federal approvals for Stibnite, remanding only certain incidental take monitoring provisions while allowing critical-path construction to continue.
Perpetua Resources (Nasdaq: PPTA) reported a Q2 2026 net loss of $97.5 million (H1 2026: $146.2 million) versus Q2 2025 net loss of $6.0 million, mainly from higher exploration and pre-development spending ahead of a planned final investment and construction decision in H2 2026.
The company ended the quarter with $574.2 million in unrestricted cash and cash equivalents and $60.9 million in restricted cash. The board of the U.S. Export-Import Bank unanimously approved a $2.9 billion senior secured long-term loan under the Make More in America Initiative to support the 100%-owned Stibnite Gold Project, with closing expected later in 2026 subject to definitive documentation.
Regulatory progress included Idaho DEQ’s final modified Clean Water Act Section 401 certification and an Idaho state district court decision upholding the project’s air permit. Perpetua started critical path construction on the Burntlog Route and worker housing, reported zero lost time incidents or reportable environmental spills, advanced a mobile modular antimony processing pilot with Idaho National Laboratory, announced new high-grade gold and antimony discoveries and a new gold-tungsten zone, and purchased $28.9 million of gold put options covering up to 158,016 ounces in 2031 at $3,000/oz.
Perpetua Resources (Nasdaq/TSX: PPTA) reported first exploratory drilling in nearly a decade at its Stibnite district in Idaho, confirming multiple high‑grade gold, antimony and tungsten intercepts at Yellow Pine and Hangar Flats. New results include 21.3 meters grading 3.2 g/t gold and 0.9% tungsten at the Clark Tunnel Fault Zone and 6.4 meters grading 16.2 g/t gold and 1.7% antimony near surface, plus 3.0 meters of 14.5 g/t gold at Hangar Flats.
Hangar Flats antimony‑tungsten holes returned up to 22.9 meters at 3.2% antimony and 1.2% tungsten, supporting tungsten as a new exploration focus and potential second critical mineral. A minimum 10,000‑meter 2026 core program is planned, with about 5,800 meters already drilled. The company highlights 3.1 million ounces of indicated and inferred gold and 99.8 million pounds of antimony located outside current reserves and has submitted U.S. grant proposals to fund tungsten‑focused drilling, sampling and metallurgical work.
Perpetua Resources (Nasdaq: PPTA), the U.S. Army and Idaho National Laboratory launched a new modular mineral processing pilot plant at INL in Idaho Falls, marked by a ribbon-cutting on July 29, 2026. The facility is designed to process antimony samples from Perpetua’s Stibnite Gold Project in central Idaho to demonstrate production of high-quality antimony trisulfide for specialized military and industrial uses.
The plant is part of a multi-year collaboration via the Defense Ordnance Technology Consortium to build a fully domestic “ground-to-round” antimony supply chain. According to Perpetua Resources, the Stibnite Gold Project hosts the only identified domestic antimony reserve, received final federal approvals in 2025, and has entered early works construction. Since 2022, Perpetua has been awarded over $87 million from the U.S. Department of War and U.S. Army, including more than $59 million in Defense Production Act Title III funds and $27 million under an Ordnance Technology Initiative Agreement, with up to $4.7 million added in June 2026.
Perpetua Resources (Nasdaq:PPTA, TSX:PPTA) published its 2025 Sustainability Report outlining ESG performance and milestones at the Stibnite Gold Project.
Highlights include 13+ years with no reportable spills, 10+ years with no lost time incidents, $159.6 million in construction-phase financial assurance, $63.4 million contributed to Idaho's economy, and over $19 million in legacy cleanup since 2021.
Perpetua Resources (Nasdaq:PPTA, TSX:PPTA) reported voting results from its June 4, 2026 virtual annual meeting. Shareholders representing 80.35% of outstanding shares were present.
All nine director nominees were elected, the board size set at nine, PricewaterhouseCoopers reappointed as auditor, and the 2026 Equity Incentive Plan approved with strong support.
Perpetua Resources (Nasdaq:PPTA) reported continued advancement of critical-path construction at the Stibnite Gold Project after a May 29 Idaho federal court decision denying a preliminary injunction sought by project opponents.
The company has begun 2026 field-season work, including the Burntlog Route, with a goal of 2029 gold and antimony production and about $45 million in contracts for Idaho businesses.
Perpetua Resources (Nasdaq:PPTA) received unanimous approval from the Export Import Bank of the United States for a $2.9 billion senior secured loan under the Make More in America Initiative to develop the Stibnite Gold Project in Idaho.
The financing, combined with existing cash, is expected to fully fund current estimated construction capital, supporting development of the only identified domestic reserve of critical mineral antimony, gold production, environmental cleanup, and an average of over 700 direct jobs per year over the mine life.
Perpetua Resources (Nasdaq:PPTA) filed unaudited Q1 2026 results and highlighted key milestones for the Stibnite Gold Project.
U.S. EXIM advanced a proposed $2.7 billion senior secured loan to a final board vote, permits and water-quality approvals progressed, safety performance was strong, and EPCM duties shifted to Hatch, while certain legal and permitting challenges remain ongoing.
