Sunshine Silver Mining & Refining Company (“SSMR”) is building the next chapter of the historic Sunshine Mine in Idaho’s Silver Valley. Since acquiring the Sunshine Complex in 2010, SSMR has invested over $200 million to expand its land position, modernize infrastructure, and advance exploration — supporting its plan to return the mine to production in 2028.
