Abstract: Lateritic bauxite deposits in Surinam have until now been modelled in two dimensions. The samples collected by auger drill are composited into 1 m (3 ft) intervals and the accumulated grade per hole used as the input for statistical and geostatistical studies. The aim of the study presented in this paper is to quantify the information lost by working with accumulated grades. In other words. the third dimension is taken into account, by considering successive slices with a thickness of 1 m. The composition of the bauxite orebody is characterised by the loss on ignition (LOI), silica, titanium oxide, iron oxide and aluminium oxide contents.
