The more significant areas requiring the use of management estimates and assumptions relate to the useful life of long-lived assets; future mining and processing plans; environmental reclamation and closure costs and timing; and estimates of fair value for long-lived assets, assets held-for-sale, and financial instruments. The Company bases its estimates on historical experience and other assumptions, including drilling and assay data that are believed to be reasonable at the time the estimate is made. Actual results may differ from amounts estimated in these Financial Statements, and such differences could be material. Accordingly, amounts presented in these Financial Statements may not be indicative of results that may be expected for future periods.</span></div>
