Dilution effects should be considered in the estimated model of deposit due to its significant impact on feasibility studies, mine planning and scheduling, milling, and stockpiling. This work compares the capacity of two approaches for modelling dilution of intrusive barren dykes into the ore body in a copper deposit. Two approaches were used to generate an undiluted model of copper grade in a copper deposit, which is cross cut by intrusive dykes. The results demonstrated that the second approach is more advantageous in comparison with the first approach, especially when there is hard contact between the ore and barren dykes.
