Cautionary Note to U.S. Investors Concerning Estimates of Reserves and Resources

Calculations with respect to "proven reserves" and "probable reserves" referred to in the technical report have been made in accordance with National Instrument 43-101, as required by Canadian securities regulatory authorities. For United States reporting purposes, the U.S. SEC applies a different standard in order to classify mineralization as a "reserve". Under SEC standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally extracted or produced at the time the reserve determination is made. No such determinations have been made with respect to any mineralization at the Liberty Project, and it cannot be assured that such a determination will be made. The report uses the terms “measured”, “indicated” and “inferred” resources. We caution U.S. investors that while such terms are recognized and required by Canadian Securities Administrators pursuant to the National Instrument 43-101, the SEC does not recognize them. U.S. investors are cautioned not to assume that any part of or all mineral deposits in these categories will ever be converted into reserves. “Inferred Resources”, in particular, 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 Securities Administration rules, estimates of Inferred Mineral Resources may not form the basis of feasibility or pre-feasibility studies. U.S. investors are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally minable.
