Sunshine Silver Mining & Refining Company (SSMRC) is revitalizing America’s most iconic silver mine. Since acquiring the Sunshine Complex in 2010, SSMRC has invested more than $250 million, expanded its land package nearly fourfold, upgraded infrastructure, and deployed modern exploration technologies to identify new resources — all advancing a plan to return the mine to production in 2028.
The Sunshine Mine is one of the world’s highest-grade primary silver projects, with a current silver endowment of 3.3 Mt @ 1,067g/t Ag (31.1 oz/ton) for 112 Moz. of Indicated Resource, and 6.4Mt @ 797 g/t Ag (23.2 oz/ton) for 165 Moz. of Inferred Resource, as described in detail in the 43-101 report available HERE
Among the world’s highest-grade silver deposits, Sunshine pairs a 140-year operating legacy with significant resources and exploration upside.
COMEX-approved for silver, and uniquely permitted to process antimony, gallium, germanium – vital defense and high-tech minerals.
Sunshine is the only U.S. site permitted to process antimony, gallium, and germanium domestically in significant quantity.
Processing its own material and third-party feed, Sunshine could meet 40% of U.S. antimony demand by 2028 (80% by 2031), while its mine alone boosts U.S. silver output by ~20%
