Mineral Resource Estimation In Grade Control Panel Using Conditional Simulation-Case Study on the Gold Mine

Abstract

In the grade control panel area, when the sampling grid is less than the size of block, the grade is highly smoothed and has very minor variability with the actual “true” value interpolated by Kriging, which is completely different with the actual block grade and tonnage-grade model. In this paper, the optimized the grade distribution and spatial variability were studies by conditional simulation in the Selective Mining Unit (SMU), avoiding the high smoothing effect by linear estimation.
