It should also be noted that the mining industry is in early stages of defining an industry-wide standard on the reporting of "all-in cash costs" hence, the definition adopted by the mining industry may differ from the Company's current definition. The Company may modify the calculation of its "all-in cash cost" to conform to the industry's standard once it is known.
Management uses all-in cash cost per ounce produced to evaluate current operating performance and for planning and forecasting of future periods. Management believes that the presentation of this new measure is useful for the investor because it allows investors to view results in a manner similar to the method used by management.
