The Stibnite Gold Project (SGP) consists of a mine site and processing facilities, associated access roads, and off-site facilities located in Valley County, in central Idaho. The mine site is located in the East Fork South Fork Salmon River (EFSFSR) drainage basin. The SGP area is a complex blend of both remote wilderness lands with high recreational values and potential wilderness characteristics, and areas impacted by historical gold, silver, antimony, and tungsten mining, processing, and resulting legacy contamination. The potentially affected area encompasses approximately 3,500 acres.
Midas Gold’s plan of operations to conduct mining operations that produce gold and silver oré, and antimony concentrates, includes open pits, ore transportation equipment, ore processing facilities, development rock storage facilities, a tailing storage facility, a water treatment facility, road construction, electrical transmission lines, and various other facilities needed to support mining activities.
The plan of operations incorporates closure and reclamation activities, and mitigation that may avoid, minimize, or compensate for adverse environmental effects caused by the SGP, and also incorporates actions that mitigate legacy contamination at locations within the mine site. Under the plan of operations, construction, operation, closure and reclamation phases of the SGP would take place over a period of approximately 20 years, not including the period of time required for long-term monitoring and maintenance. Environmental monitoring and maintenance would continue for as long as needed to demonstrate that the site has been fully reclaimed.
This is a hardrock mine and legacy clean up project that incorporates development and production of a listed critical mineral (antimony), gold and supporting infrastructure.
The purpose and objectives for the Project for Midas Gold are to:
• Economically develop and operate a modern mining operation at the Stibnite site;
• Fund the reclamation and restoration aspects of the Project;
• Obtain financial return and benefits from its property rights and investment; and
• Supply extracted minerals for various uses, including antimony which is a designated critical mineral and essential to support renewable energy generation and manufacturing processes.
This would be accomplished while providing broader environmental restoration and socioeconomic benefits at the site and for the surrounding area.
