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; estimates of fair value for asset impairments; valuation allowances for deferred tax assets; reserves for contingencies and litigation; and estimates with respect to assumptions regarding stock-based compensation expense. 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.</font> </div>
