Drilling Advances 2027 Sunshine Mine Feasibility Study, Supports Near-Mine Growth Potential in Upper Country and Planned Return to Production in Late 2028 KELLOGG, Idaho, July 23, 2026 /PRNewswire/ -- Sunshine Silver Mining & Refining Company (the "Company" or "Sunshine") (NYSE: SSMR), a mining company advancing the next chapter of American silver, today announced new results from its ongoing 50,000-metre drilling program at the Sunshine Mine, located in Idaho's Silver Valley. As the largest mineral rights holder in the Silver Valley, Sunshine offers untapped exploration potential both near-mine and at district scale.

A disappointing IPO leaves the company with a short cash runway, and additional capital injection will likely be needed. Market conditions for Silver and Antimony are highly encouraging for medium-term prospects.
