The main cut-off parameter determining quality of iron ore reserves is the cut-off grade of Fe magn. It is proposed a method for choosing the optimum values of cut-off grade Fe in evaluation of BIF deposits on the example of one of the West Azov deposits. Dynamics of reserves’ quantity and quality have analyzed depending on changes in cut-off grade, and fluctuations in average grade have been taken into account.. The optimal values of cut-off grade of Fe magn within 12-14 % are substantiated using geostatistics and spatial modeling.
