The Cu-Ag deposit exploited in the Lubin-G?og?w Copper district (LGCD) in Poland is located in the Permian Rotliegend (sandstones) and Zechstein (shale and carbonate rocks) formations. The three main lithological series are not internally homogenous; within them, a total of 16 individual lithological units can be determined. The differentiation between lithological, mineralogical and geometallurgical ore properties is a criterion used to distinguish between main and individual lithologies in the deposit area. A sy...

The paper presents the results of the analysis of the accuracy of estimates of copper resources in parts of a Cu-Ag deposit in the Lubin-Glogow Copper District (LGCD) (Poland) where samples were not collected (test areas). The estimation was based on the samples collected from excavations surrounding the areas scheduled for mining activities, while the evaluation of the accuracy of the estimates was based on data obtained during the exploitation. The estimates of resources in the examined area were based on a 3D s...
