Here are the 424B prospectus supplements from Sunshine Silver Mining & Refining Company (SSMR) in our archive over the last 12 months, newest first, and each one links through to the document itself with the summary and the scores our analysis gives it.
A 424B covers the supplement that carries the terms of a priced offering, so if you follow SSMR and want that one kind of document rather than the whole filing history, this is the page to keep. The company's other filings, of every form, are on the full SSMR filings page.
Sunshine Silver Mining & Refining Company is offering 20,000,000 shares of common stock in a firm commitment initial public offering at an initial public offering price of $13.50 per share, with underwriters’ option to purchase up to 3,000,000 additional shares within 30 days.
