To assess the content of Al2O3 in the exploration block of one area of Sangaredi bauxite field (the Repubtic of Guinea, West Africa), there was applied one of geostatistics method - discrete Kriging. The use of discrete Kriging in these terms altows for more reliability to provide tightly controlled value, namely, not less than 48 % Al2O3 content in the concentrate when shipping it with concentrator on bulk carriers. This problem becomes all the more urgent because of the rich oil field areas is becoming less.
