October 3, 2024
Contact: Dana Swift, Remediation Bureau Chief, [email protected]
BOISE - The Idaho Department of Environmental Quality (DEQ) received an application from Perpetua Resources Idaho, Inc. for a permit to construct, operate, and close a cyanidation facility intended to contain, treat, or dispose of process water containing cyanide.
In accordance with the "Rules for Ore Processing by Cyanidation" (IDAPA 58.01.13), Perpetua Resources is requesting a permit to operate a cyanidation facility as part of the Stibnite Gold Project (SGP), a proposed gold mine located in Valley County, approximately 12 miles east of Yellow Pine, Idaho. The SGP is located on private and public lands within the Boise and Payette National Forests. Perpetua has 29,827 acres of mining claims comprised of both unpatented (28,477 acres) and patented (1,350 acres) claims. The mine is also located within the historical Stibnite Mining District, an area characterized by previous mining activities including underground mine workings, rock dumps, tailings deposits, and open pits, including the Yellow Pine Pit.
The cyanide permit application is available for review at DEQ's State Office (1410 N. Hilton Street, Boise, Idaho), Boise Regional Office (1445 N. Orchard Street, Boise, Idaho) and on DEQ's website. Currently, DEQ is not accepting public comments on the contents of the permit application.
Upon receipt of the permit application, DEQ will perform a completeness review within 30 days. If the application is deemed complete, DEQ will have 90 days to reject the application or issue a draft permit. DEQ will issue a public notice in both cases.
If DEQ prepares a draft permit, a 60-day public comment period will begin on the date of the public notice. Within 30 days of the public notice for the draft permit, a public meeting will be held where oral or written comments may be provided. DEQ will address public comments submitted in its Response to Public Comments. All comments must be submitted in writing during the public comment period.
