A method of ore reserve estimation based on the assumption that a linear relationship exists between the grade difference and the distance between all drill Another method, known as the triangle method, requires that we connect adjacent holes into triangles. The included area of each triangle is assigned the characteristic not of a single hole, but of the weighted average of the three holes forming the triangle. The weighting of the three holes is based on the length of the drill holes. Triangular method is and extended approach of the polygon method.

For reserve estimation volume and density parameters must be included into calculations. To include the volume parameter into calculations the width of a block (on XY plane) must be obtained. Therefore, in order to obtain the influence area borders of cross-sections the same method, which was applied to the drillings, was applied to the cross-section paths. The standard method of making these estimates is to find the cubic contents of triangular prisms, in the apexes of which the drill holes are placed, by multiplying the surface area by the average depth of the ore in the three drill holes and then multiplying the cubic contents by the specific gravity of the ore or rock to find the tonnage. The main objective of ore reserve estimation is to as accurately as possible define the extent (size) and value (grade) of a mineral deposit. We are confronted with two primary objective of this process and these are: 1.
