Cautionary Note Regarding Estimates of Measured, Indicated and Inferred Resources
The United States Securities and Exchange Commission permits 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 use certain terms, such as “measured,” “indicated,” and “inferred resources,” that the SEC guidelines strictly prohibit us from including in our filing with the SEC. U.S. investors are cautioned not to assume that any or all of measured, indicated or inferred resources are economically or legally mineable or that these resources will ever be converted into reserves. U.S. investors are urged to consider closely the disclosure in our Form 10-K and Form 10-Q. You can review and obtain copies of these filings from the SEC Filings page of Hecla's website or the SEC's website at http://www.sec.gov/edgar.shtml.
