economic studies. United States investors are cautioned not to assume that all or any part of measured or indicated mineral resources will ever be converted into mineral reserves. United States investors are also cautioned not to assume that all or
any part of an inferred mineral resource exists, or is economically or legally mineable. </I></P>
