What Sunshine Silver Mines Corp (SSMC) does

Sunshine Silver Mining & Refining Company (NYSE: SSMR) is a publicly traded, pre-revenue U.S. silver mining and refining company headquartered in Kellogg, Idaho. It is advancing the historic Sunshine Mine in Idaho's Silver Valley, which hosts 104 million ounces of Indicated silver resources at 1,022 g/t and 160 million ounces of Inferred resources at 775 g/t — among the highest-grade primary silver deposits globally — over a 9,561-hectare consolidated land position that includes a permitted onsite silver/copper refinery with historical COMEX-deliverable production. The company has digitized more than a century of geological records into a 3D mine model to guide exploration and mine planning, and is evaluating additional value from by-product copper, lead, and antimony, plus optionality on critical minerals such as gallium and germanium.\n\nThe company's planned business model is commodity metals production and refining: at approximately 1,000 tonnes per day, the mine is expected to produce an average of approximately 6.7 million ounces of silver per year in its first five years of production and approximately 5.8 million ounces annually over a 24-year mine life, with by-product credits from copper, lead, and antimony. Sales are expected to flow through direct channels to commodity markets and industrial buyers, leveraging COMEX-deliverable credentials from the permitted refinery. Stated target customer segments are U.S. national security and defense, clean energy (solar, EVs, storage), and high-tech industries requiring high-purity silver and traceable domestic critical minerals.\n\nThe asset was acquired and developed by The Electrum Group beginning in 2010, with over $200 million of sponsor capital deployed before the company completed its IPO on NYSE in June 2026, raising approximately $310.5 million in gross proceeds at $13.50 per share. Electrum is expected to remain the majority stockholder post-IPO. Leadership includes CEO Heather White and Chairman Dr. Thomas Kaplan (Electrum). The company is in pre-production with a planned return to production in 2028.

Revenue model

1. Silver Production: Pre-revenue mining company planning to return to production in 2028. Expected to produce approximately 6.7 million ounces of silver per year in its first five years of production at approximately 1,000 tpd, and approximately 5.8 million ounces annually over a 24-year mine life.
2. By-product Credits (Copper, Lead, Antimony): The mine also produces copper, lead, and antimony as by-products. The company is evaluating additional value opportunities through silver/copper refining and antimony production. These by-product credits have not yet been captured in the technical report summary but are being substantiated by drill programs.
3. Refining Services: The company controls a permitted onsite silver refinery with historical COMEX-deliverable silver production and future processing optionality. This provides vertical integration and potential future revenue from refining third-party concentrates.
