Cautionary Note to U.S. Investors-The United States Securities and Exchange Commission permits U.S. mining companies, in their filings with the SEC, to disclose only those mineral deposits that a company can economically and legally extract or produce. We may use certain terms in public disclosures, such as "measured," "indicated," "inferred” and “resources," that are recognized by Canadian regulations, but that SEC guidelines generally prohibit U.S. registered companies from including in their filings with the SEC. U.S. investors are urged to consider closely the disclosure in our Form 10-K which may be secured from us, or from the SEC's website at http://www.sec.gov.Additional Information and Where to Find It This document relates to Coeur D’Alene Mines Corporation’s (“Coeur”) proposed acquisition (the “Transaction”) of Orko Silver Corp.
