(Incorporated in Delaware)

We are a development-stage mining company that owns the Sunshine Mine, which we are developing. We also own refining facilities in Kellogg. We own a historically producing silver mine whose byproducts include antimony, copper and lead.

We are involved with maintaining and modernizing this site to prepare for a targeted restart in 2028 of mining, milling and refining operations. 

Note: We own and lease land at the Sunshine Mine Core Area, the Coeur d’Alene Mining District and the Lakeview Mining District.

Note: We acquired the Sunshine Mine in 2010 but have not yet generated any operating revenue.

Note: Net loss is for the 12 months that ended March 31, 2026.

(Note: Sunshine Silver Mining & Refining priced its IPO at $13.50 – the low end of its range – and sold 19 million shares – the number in the prospectus – to raise $270 million on Wednesday night, June 3, 2026. Background: Sunshine Silver Mining & Refining disclosed the terms for its IPO on May 26, 2026, in its S-1/A filing: 20 million shares at a price range of $13.50 to $16.50 to raise $300 million, if priced at the $15.00 mid-point of its range. Background: Sunshine Silver Mining & Refining filed its S-1 for its IPO on May 11, 2026, without disclosing the terms. Estimated proceeds were $100 million, a placeholder figure. Some IPO pros had estimated that Sunshine Silver Mining & Refining’s IPO could raise as much as $400 million.)
