In the last two decades, the application of computer in mining industry has showed a rapid development with great success especially in the field of ore reserve estimation. Treatment of huge data set in an accurate and fast manner was a dream of the scientists working in the field of reserve estimation and sampling methods. This project aims to estimate the ore reserves in three parts of Upper Egypt, namely Wadi Kalabsha kaolin, Abu Ghalaga ilmenite deposit and Sukari gold. The three selected ores with different geological features were tested here, using different sampling points (number and distribution). Calculation of ore reserves using computer-aided have been done using triangular method and kriging technique to see which one is better in implementation. The ore reserve estimation as well as the estimation of the average thickness, and average assay of the deposits under study were carried out using Excel software, while, kriging technique was implemented using VARIOWIN 2.2 and GSLIB software’s. Not to mention, data were screened at the primary stage of calculations using summary statistics and the results were introduced in the form of tables, reports, contour maps, and 3D representations of the variables. While the triangular method showed success in determining the average assay and reserves of the stratified deposit (Kalabsha kaolin) and the lens of Abu Ghalaga ilmenite, it failed with the gold reserves of Sukari, where kriging technique showed better and more reliable results. In all cases our task was to provide a robust, accurate, and easy use tool that would assist the mining industry. On the other hand, we have prepared a database for the three deposits to be added to the Mining Information System (MIS), Software developed in 2003 by a group of computer applications in mining (camG) at the Mining Engineering Department of Assiut University.
