Without limiting the foregoing, this Annual Report uses theterms "measured", "indicated" and "inferred" resources. United States investorsare advised that, while such terms are recognized and required by Canadiansecurities laws, the SEC does not recognize them.

United States investorsare cautioned not to assume that all or any part of measured or indicatedresources will ever be converted into reserves. Further, "inferred resources"have a great amount of uncertainty as to their existence and as to whether theycan be mined legally or economically. It cannot be assumed that all or any partof the "inferred resources" will ever be upgraded to a higher category.Therefore, United States investors are also cautioned not to assume that all orany part of the inferred resources exist, or that they can be mined legally oreconomically.
