Based on the MCA model, the ore tonnage–thickness model and the metal tonnage–grade∙thickness model are also derived. For the tonnage–thickness model, a curve of ore tonnage vs. orebody thickness can be obtained by calculating the CA model for the orebody thickness contour map and by estimating one ore tonnage value via the FMRE model.
