About Us


Sunshine Silver Mining & Refining is a privately-held U.S. based silver company that is advancing its two principle projects, the Sunshine Mine in Idaho and the Los Gatos Project in Chihuahua, Mexico.

The Sunshine Mine deposit is one of the highest grade large primary silver deposits in the world with a resource of 75 million measured & indicated and 221 million inferred silver ounces at an average grade of 827 grams per tonne. The Company also owns the Sunshine Precious Metals Refinery adjacent to the Sunshine Mine and is the only silver mining and processing company in North America that is fully integrated and certified to sell high purity silver directly to the COMEX in New York.

The Los Gatos Project is a joint venture between Sunshine Silver Mining & Refining Corp (Sunshine Silver) and Dowa Metals & Mining Ltd (Dowa) where Sunshine Silver has 70% ownership and is the operating partner. The project is comprised of 103,000 contiguous acres of mineral rights that define a new silver-dominant polymetallic mineral district. The Cerro Los Gatos Zone within this district currently contains approximately 100 million silver ounces, over 1.5 billion pounds of zinc, 800 million pounds of lead and 135 thousand ounces of gold. Cerro Los Gatos is now being developed into Sunshine Silver’s first operating mine.
