Embodiments provide methods and systems for modeling a proposed geological volume. One such embodiment begins by digitally creating a three-dimensional (3D) model of a geological volume that includes one or more variables, each of which is a mathematical factor in an analysis confidence of one or more sub-volumes of the volume. Next, standardized values for each of the one or more variables are defined. In turn, the analysis confidence, e.g. mined, ore quality, etc., of the one or more sub-volumes is mathematically determined. Finally, the model is updated to include the determined analysis confidence of the one or more sub-volumes.
