CAUTIONARY STATEMENT REGARDING TECHNICAL INFORMATION : This presentation contains information regarding mineral resources estimated at the mineral projects referenced herein. Mineral resources are not mineral reserves and do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, socio- political, marketing or other relevant issues. In particular, the quantity and grade of reported inferred mineral resources are uncertain in nature and there is insufficient exploration to define these inferred mineral resources and an indicated or measured mineral resource in all cases. It is uncertain in all cases whether further exploration will result in upgrading the inferred mineral resources to an indicated or measured mineral resource category.
