The distribution of gold minerals in the vein dependson the initial formation caused by hydrothermal process. The investigation in this work is related to the gold (Au) mineralization in Penjom Gold Minein the state of Pahang, Malaysia. Gold mineralization in Penjom can be described as sheeted orogenic mesotermal veins and dissemination deposit in Permian sedimentary sequence of fine-grained sediments and volcanics. Variogramcalculation results of gold values from 304 drill hole data obtained showthat anisotropyphenomenon occurs in east-west direction which the minor range a1=720 meters and major range a2=2397 meters, whilein southeast-northwest direction the minor ranges is a1=935 meters and the major a2=3401 meters. Isotropyphenomenon occurs in the southwest-northeast and north-south directions with each range of a = 1622 meters and a = 2143 metersrespectively. After the release of 88databased on variogram calculations of data outliers, anisotropy phenomenon still occurs in east-west direction with each a1=199 meters and a2=4828 meters, while in southeast-northwest direction the rangesarea1=1316 meters and a2=1829 metersrespectively. Isotropy phenomenon occurs in southwest-northeast and north-south with the same range of a=1543 meters. In trials with various active lag 823.95, 411 975 and 205. 987, the drift occurs in east-west and northwest-southeast, and indicating similarty with the directionsof lithologic structures. Key words: Geostatistics, areaof influence, drift effect.
