Sunshine Mining NYSE

Sunshine Silver Mining & Refining Co. owns and controls the Sunshine Mine, one of the highest-grade pure silver resources globally. The average diluted silver grade in indicated mineral resources reaches 1,022 grams per ton, approximately three times the grade of other high-grade silver mineral assets worldwide. The mine holds 103.9 million ounces of indicated silver resources and 159.8 million ounces of inferred silver resources.

According to the plan, the Sunshine Mine is expected to produce approximately 6.7 million ounces of silver annually in the first five years of operation, and about 5.8 million ounces annually over its 24-year mine life, making it the second-largest primary silver mine in the United States. The company is also one of the few in the U.S. with a vertically integrated platform, capable of integrating mine, mill, and refinery operations within permitted boundaries, with the potential to produce silver and antimony on-site.

As a potential hub for critical mineral supply, the Sunshine Mine historically contained economic quantities of antimony, producing over 48.4 million pounds of finished antimony between 1953 and 2001. Currently, the company is evaluating the design and engineering plans for the already permitted Sunshine Antimony Plant, which, if operational, could produce up to 34.5 million pounds of finished antimony annually, potentially meeting up to 60% of U.S. demand for this critical mineral.

Heather White, CEO of the company, noted that the NYSE listing is a significant step toward execution. Recent efforts have focused on completing infill drilling and engineering to support the Sunshine Mine feasibility study, targeted for completion in early 2027. Thereafter, the company will proceed with constructing the mill and upgrading infrastructure, aiming to achieve silver production by the end of 2028. She stated that the Sunshine Mine already holds the necessary permits, with existing infrastructure valued at approximately $600 million, and $208 million invested over the past 16 years in exploration, maintenance, and modernization.
