The Sunshine Mine is one of the world’s highest-grade primary silver projects, with current mineral resources of 3.5 million tonnes at 1,022 g/t silver for 104 million ounces of Indicated silver resources and 7.1 million tonnes at 775 g/t silver for 160 million ounces of Inferred silver resources. Located in Idaho’s Silver Valley, one of the most productive silver regions in the United States, the Sunshine Mine has produced more than 360 million ounces of silver over its operating history.

Since acquiring the Sunshine Complex in 2010, Sunshine Silver Mining & Refining Company has invested over $200 million to expand its land position, upgrade infrastructure and apply modern exploration technologies to a historically significant silver system. For the first time in the mine’s history, more than a century of geological records have been digitized into a 3D mine model, providing new tools to evaluate the mine’s extensive workings and identify future exploration opportunities.

Today, Sunshine is advancing a plan to return the Sunshine Mine to production in 2028. With a high-grade silver resource, significant operating history, existing infrastructure and an expanded land position in the Silver Valley, Sunshine is building the next chapter of American silver.
