Analysis the effects of Mineral Reserve Geometric factors on modelling technics with emphasis on vein Reserves (case study: Taknar copper vein deposit)

The main objective of deposit estimation is prediction of physical properties of reserves based on sample analysis and modelling of dimension, shapes and grade distribution. Numerous factors such as shape, depth, dimensions and grade distribution effect on deposit modelling process. In this research, with evaluation on copper vein deposit, the effects of geometric factors constrains on modeling process evaluated. Also the suitable modelling technics for increasing the accuracy of modeling suggested. Whole of exploration information analyzed based on gathered data from 1457 m conventional core drilling boreholes, 4839 m Reverse Circulation boreholes and 2685 m production boreholes.
For increasing the accuracy, the modelling performed with creation of topograghic DTM, fault models, 3D model of boreholes, and mineralization. Based on assuming the 0.28 percent grade as cutoff grade, the reserve estimation with kriging and Inverse distance performed. The estimated reserve tonnage in kriging and Inverse distance are equal to 118250 and 125150 tone.
