The preparation of the Company’s consolidated financial statements requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and the related disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of expenses during the reporting period. The more significant areas requiring the use of management estimates and assumptions relate to environmental reclamation and closure obligations; asset useful lives utilized for depletion, depreciation, amortization and accretion calculations; fair value of equity investment and the impairment test; recoverable gold in leach pad inventory; current and long-term inventory; mine development capitalization costs; the collectability of value added taxes receivable; the amount of mineral reserves; valuation allowances for deferred tax assets; income and mining tax provisions; and reserves for contingencies and litigation. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results may differ significantly from these estimates. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 12pt 0pt;">References to “C$” refer to Canadian dollar.</p>
