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 U.S. securities laws. Without limiting the foregoing, this news

release refers to a technical report that uses the terms “measured”, "indicated" and "inferred" mineral resources.

U.S. investors are cautioned that, while such terms are recognized and required by Canadian securities laws , the

SEC under Industry Guide 7 does not recognize them. Under U.S. standards, mineralization may not be classified

as a "reserve" unless the determination has been made that the mineralization could be economically and legally

produced or extracted at the time the reserve determination is made. U.S. investors are cautioned not to assume

that all or any part of measured or indicated resources will ever be converted into reserves. U.S. 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, U.S. 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 U.S. companies subject to the reporting and disclosure requirements under Industry

Guide 7 of the SEC.
