    The aim of study has been characterization of anisotropy of parameters variability of the $Cu-Ag$ Lubin deposit (located in SW Poland). The researches were based on results of sampling of cores from boreholes and mine workings (channel samples). Basic deposit parameters were analyzed: $Cu$ content, thickness of deposit and accumulation index. A research of directional differentiation of variability was made by geostatistical methods. Adjustment of theoretical models to empirical semivariograms has been checked by means of procedure Cross Validation. Geostatistical analysis didn't reveal any significant anisotropy of deposit parameters variability. Only in few cases anisotropy of parameters variation is essential.
