“AISC Margin” is anon-GAAP financial measure calculated as the difference between the realized gold price per ounce and“All-in sustaining costs” (AISC) per ounce for the relevant period. Management uses this metric to assess the efficiency of our gold mining operations and to evaluate the ability of our assets to generate cash flow in excess of sustaining expenditures. This measure does not have a standardized meaning under IFRS and should not be considered in isolation or as a substitute for measures prepared in accordance with IFRS. Other companies may calculate AISC Margin differently and therefore it may not be comparable to similar measures presented by other companies.
