Gold Mining Stock Valuation

A general observation about the nature of mining, which typically involves extracting, lifting, transporting, milling and processing tonnes of ore, suggests that mining costs are determined, to a first order approximation, by the total number of tonnes to be handled and not by the metal content of each tonne. That is, the costs of extracting, lifting, transporting, milling and processing for a tonne of ore does not change whether the tonne contains a small amount of metal (low grade ore) or a large amount of metal (high grade ore). Therefore, high grade ore, or ore that has a higher metal value per tonne, is necessarily more valuable. High grade deposits have more robust economics, are less sensitive to changes in resource prices and typically may be developed with lower CapEx spending. Of course, dilution factors (not all ore can be mined) and metallurgical factors (not all metal in the ore can be extracted) do come into play and cause variances between deposits.
