This presentation contains "forward-looking statements" within the meaning of applicablesecurities laws, including statements relating to life of mine production plans and explorationplans, the Cerro Bayo restart plan and the growth and strategy of Mandalay. Readers arecautioned not to place undue reliance on forward-looking statements. Actual results anddevelopments may differ materially from those contemplated by these statements depending on,among other things, that exploration results at Cerro Bayo, Costerfield, and La Quebrada may notmeet management’s expectations, that Cerro Bayo and Costerfield capital, production andoperating cost results may not meet current plans, that reclamation costs associated withMandalay’s Furioso property may exceed current estimates, and changes in commodity prices andgeneral market and economic conditions. The factors identified above are not intended torepresent a complete list of the factors that could affect Mandalay.
