Interpolation of iron grades of ores of the Yakovlevskoye deposit using MultipleIndicator Kriging method allowed taking into consideration mixed accumulations, which had been identified using statistical analysis of iron grade distributions of iron-rich ores. Using Indicator Kriging, there was carried out probabilistic logging of different ore types (paint, blueing) and barren rocks within the bounds of the first-priority development zones of the Yakovlevskoye deposit. That allowed taking into consideration density values of different ore types by reserve estimation.
