Forward-looking statements involve known and unknown risks,uncertainties and other factors that may cause the actual results or events todiffer materially from those anticipated in such forward-looking statements. Thisis particularly the case with respect to forward-looking statements containedin the past Bisha Technical Reports and the Updated Timok PEA. Thesestatements speak only as of the date of this Form 40-F/A.

-  estimates of the quantity, quality    and the realization of mineral reserves and resources, the conversion of    mineral properties to reserves and resources as set out in the Bisha Technical    Reports concerning the Bisha Property and the Updated Timok PEA concerning the    Timok Project; 
-  interpretation of drill results as    such information constitutes a prediction of what mineralization might be found    to be present if and when a project is actually developed;

-  any pending litigation to which    the Company is a party;
-  the timing and success of    improving the quality of the copper and zinc circuit products by resolving the    metallurgical challenges from the variable ore materials being processed to    produce concentrate from both circuits;
-  the effect on resource or reserve    estimates due to the possible inability to resolve the metallurgical challenges    on the variable ore materials being processed on a timely basis or at all;
-  the potential to expand resources,    reserves and mine life;
-  exploration, environmental, health    and safety initiatives;
-  future exploration budgets, plans,    work programs and capital expenditures;

Although theCompany has attempted to identify important factors that could cause actualresults to differ materially from those contained in forward-lookingstatements, there may be other factors that could cause actual results todiffer from what is anticipated, estimated or intended. The Company’sforward-looking statements are based on the beliefs, expectations and opinionsof management on the date the statements are made and the Company assumes noobligation to update such forward-looking statements in the future, except asrequired by law.  There can be no assurance that such statements will prove tobe accurate, as actual results and future events could differ materially fromthose anticipated in such statements.
