Perpetua Resources Corp. has advanced construction at its Stibnite Gold Project in central Idaho, with key milestones including the delivery of worker housing units and the upholding of federal approvals.
By August 24, approximately half of the modular worker housing units supplied by ATCO had been delivered to the site, while the remainder were stored roughly 120 kilometers away in Cascade. The project, located in central Idaho, has also seen the manufacturing of two autoclaves for its processing facility underway at a European facility.
Federal approvals for the Stibnite Gold Project were upheld on August 18 by the U.S. District Court for Idaho, which rejected challenges under the National Environmental Policy Act, the General Mining Law and the National Forest Management Act. The court remanded the matter back to the U.S. Fish and Wildlife Service for clarifications regarding monitoring and reporting measures in the Incidental Take Statements, with plaintiffs filing an appeal.
Construction progress follows the July 29 inauguration of a modular mineral processing plant in Idaho Falls, developed in collaboration with the U.S. Army and the Idaho National Laboratory. Since 2022, Perpetua Resources has received over $87 million in funding from the U.S. Department of Defense and the U.S. Army.
On-site operations include a drilling program with four rigs currently active. Approximately 5,800 meters of a planned 10,000-meter program have been completed. Recent drilling results from the Clark Tunnel Fault Zone included intercepts of 6.4 meters grading 16.2 grams per ton of gold and 1.7% antimony from the surface, as well as 15.0 meters grading 6.3 grams per ton of gold and 0.8% antimony starting at 11 meters depth. A separate gold-tungsten discovery yielded 21.3 meters grading 3.2 grams per ton of gold and 0.9% tungsten from 24 meters depth.
Additional drilling at Hangar Flats returned intercepts including 22.9 meters of 3.2% antimony and 1.2% tungsten.
