CAUTIONARY NOTE TO UNITED STATES INVESTORS

This news release contains disclosure that has been prepared in accordance with the requirements of Canadian securities laws, which differ from the requirements of US securities laws.

US investors are cautioned that, while such terms are recognized and required by Canadian securities laws, the SEC does not recognize them.

US investors are cautioned not to assume that all or any part of indicated resources will ever be converted into reserves. US investors should also understand that "inferred resources" have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. It cannot be assumed that all or any part of "inferred resources" will ever be upgraded to a higher category. Therefore, US investors are also cautioned not to assume that all or any part of inferred resources exist, or that they can be mined legally or economically. Accordingly, information concerning descriptions of mineralization and resources contained in this news release may not be comparable to information made public by US companies subject to the reporting and disclosure requirements of the SEC.
