of gold from operations AISC reported in the FS includes total cash costs sustaining capital expansion capital and closure costs but excludes corporate general and administrative costs and salvage AISC per Ounce is calculated as AISC divided by payable gold ounces and copper silver credits Cautionary Note to U S Investors Concerning Estimates of Mineral Resources Mineral resource estimates have been prepared in accordance with the requirements of Canadian securities laws which differ from the requirements of U S securities laws The terms mineral resource measured mineral resource indicated mineral resource and inferred mineral resource are defined in NI 43 101 and recognized by Canadian securities laws but are not defined terms or recognized under U S securities laws U S investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be upgraded to mineral reserves Inferred mineral resources have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category Under Canadian securities laws estimates of inferred mineral resources may not form the basis of feasibility or pre feasibility studies U S investors are cautioned not to assume that all or any part of an inferred mineral resource exists or is economically or legally mineable Accordingly these mineral resource estimates and related information may not be comparable to similar information made public by U S companies subject to the reporting and disclosure requirements under the U S federal securities laws and the rules and regulations thereunder
