models for mineral reserves estimation is to train them using an existing borehole dataset of a mineral deposit and appropriate learning methods [1–5]. In this study, the application of NN and ANFIS and the issues involved with using them for reserve estimation were elaborated with the help of a drill-hole dataset of a copper deposit.

At some deposits the definition of their mineral resources and ore reserves requires an accurate estimation of the deleterious components. In particular, these are the contents of SiO 2 and Al 2 O 3 at iron ore deposits (Abzalov et al. 2010 ), and the contents of SiO 2 and Fe 2 O 3 at bauxite deposits (Abzalov and Bower 2009 );
