Sunshine Silver Mining & Refining ^{Priced, NYSE: SSMR}

We are the owner and developer of the permitted Sunshine Mine and the Sunshine Silver/Copper Refinery, as well as the associated facilities including the Sunshine Tailings Storage Facility and historical antimony refinery grounds. The Sunshine Mine is a historic, permitted, large-scale past-producing silver mine in the United States, which historically also produced meaningful quantities of antimony, copper and lead. The Sunshine Mine is one of the highest-grade primary silver resources in the world, with an average diluted silver grade of 1,022 grams per tonne of Indicated Mineral Resources and 776 grams per tonne of Inferred Mineral Resources. When production is restarted, we expect the Sunshine Mine will also be one of the largest silver mines in the United States. We have the major permits required to restart mining, milling and refining operations, and we will not require an environmental impact study to initiate restart of such operations. Our mining, milling and refining complex includes substantial installed infrastructure, including approximately $208 million of investments that we have made over the last 16 years to maintain and modernize the Sunshine Complex and to consolidate the highly prospective land package surrounding the Sunshine Mine. We plan to restart operations at the Sunshine Complex in 2028.
