Sunshine Silver Mining IPO: silver mines owner listed on NYSE

Preliminary trading of Sunshine Silver Mining & Refining shares has begun on the Freedom client trading system. Sunshine owns the Sunshine Mine in Idaho, one of the largest silver mining regions in the United States. The company also owns antimony, copper and lead refining operations. Later on June 4, the company's securities will appear on the NYSE under the ticker SSMR.

Sunshine Silver Mining & Refining raised $270 mln as a result of IPO. The company placed 20 mln shares at $13.5 per paper: this valuation is at the lower end of the previously announced price range ($13.5-16.5). Based on the IPO results, the company's value can be estimated at $1.9 bln, Bloomberg estimates.

The deal was organized by Morgan Stanley, BMO Capital Markets and Scotia Capital, as well as Citigroup, RBC Capital and Canaccord Genuity.

Sunshine Silver, founded in 2010, specializes in the acquisition, development and operation of precious metals-related assets in North America.

Specifically, the company is working to reopen and expand the previously closed Sunshine mine in Idaho's Silver Valley, one of the largest historic silver mining regions in the U.S., Reuters wrote. Sunshine Silver plans to restart production at the mine by 2028 to produce antimony as well as copper and lead by-products. The company completed a $75 million financing round in September 2025.

According to documents filed with the U.S. Securities and Exchange Commission (SEC), the company is not yet generating revenue, and in the first quarter of 2026, its net loss was $13.3 million - more than triple the loss for the same period in 2025. The loss for all of 2025 totaled $34.7 million.

Over the past 16 years, Sunshine Silver has invested about $208 million to expand its land assets and modernize its mining infrastructure, it said in its IPO filing.

Investors in Sunshine Silver Mining & Refining include The Electrum Group and Ospraie Management. Electrum will retain over 50% of the outstanding shares in Sunshine Silver following the completion of the IPO.

The average cost of its closest peers per ounce of silver is $6.36: taking this into account and Sunshine Silver's resource base of 277 million ounces of silver, the company's business value can be estimated at $1.76 billion, Freedom Broker analyst Alem Bektemirov said. Taking into account debt and cash on the balance sheet, the equity value is estimated at $1.78 billion, or $12.63 per share: that's 6.3% below the lower end of the stated price range of $13.5 per share, Bektemirov added.

Among the main risks, the Freedom Broker analyst highlighted the company's dependence on one asset, the Sunshine mine in Idaho: no proven or probable mineral reserves have been identified, and the cost, timing and complexity of converting mineral resources to reserves may be higher than the company expects.

The company's valuation looks "quite aggressive" given the current stage of the company's development, Bektemirov summarized. Sunshine Silver Mining shares, he believes, could be "an interesting speculative position" for investors who want exposure to silver and are willing to wait until 2028.

Sunshine stock could also be an unexpected indirect bet on the artificial intelligence revolution due to demand for metals for wiring in data centers, Barron's suggested.

Sunshine Silver's listing comes at a time when other mining companies are considering IPOs, Reuters reports. In particular, Barrick Mining is studying the possibility of offering shares of its North American gold mining business, and McEwen Copper plans to hold an IPO and raise about $300 million by the end of the year to finance its copper project in Argentina.
