Economic Evaluation

Vulcan 's flexible block sampling facilities allow the user to manipulate the values for each block according to user defined conditions. It is common practice to calculate the economic value of each block according to variable commodity prices to calculate sensitivity to varying prices. In multiple mineral deposits the economic value for each block is often used as the indicator of ore or waste.

The economic values can be contoured and shells created from the contours. This makes for easy 3 dimensional analysis of orebodies that are not lithologically bound. Grade shells for various cut off grades can quickly be calculated and sensitivity analyses carried out. Of course the results are available for analysis using the statistical tools described above.
