Nonmetallic mineral resources are the object for extraction during ore development at Stoilenskoe deposit. Objective estimation of sources, volume and conditions of iron ore (as main raw material) extraction is the actual and complicated problem. Two methods of resources calculation, such as the method of geological blocks and the method of vertical parallel sections, have been presented in the paper.
