Cautionary Notes to U.S. Investors

The United States Securities and Exchange Commission (SEC) permits U.S. mining companies, in their filings with the SEC, to disclose only those mineral deposits that the company can economically and legally extract or produce. We use certain terms on this website (or in press releases available on this website) such as ‘measured resources’, ‘indicated resources’, and ‘inferred resources’, which the SEC guidelines strictly prohibit U.S. registered companies from including in their filings with the SEC.

Cautionary Note to U.S. investors concerning estimates of Measured and Indicated Resources
This website uses the terms “measured” and “indicated resources”. We advise U.S. investors that while those terms are recognized and required by Canadian regulations, the U.S. Securities and Exchange Commission does not recognize them. U.S. investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into reserves.

Cautionary Note to U.S. investors concerning estimates of Inferred Resources
This website uses the term “inferred resources”. We advise U.S. investors that while this term is recognized and required by Canadian regulations, the U.S. Securities and Exchange Commission does not recognize it. “Inferred resources” have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an Inferred Mineral Resource will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Resources may not form the basis of feasibility or other economic studies. U.S. investors are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally minable.
