It proposed the Accepted 23rd Jan. 2022 priority for the exploration using the conventional technique combined Available online 28th Feb. 2022 with the geological mathematic method. The research essentially Keywords summarized that the study area had a complex geological and structural Attapeu setting the mineralization zones or gold orebodies most likely formed as a Gold exploration network lens shape and or mineralized single vein or vein zone extending from a few tens of meters to greater than 500 meters long within a single dipping Group of mines angle of 450 800 the geometric of orebodies likely illustrated as small to Lao PDR. medium size. The mineralization zone significantly extended following the geological setting indicating consistent to the strongly inconsistent group Vm . Medium- to high-grade gold ores are commonly found in each ore body and identified as a homogeneous to strongly inhomogeneous group Vc 785 . Regarding the exploration criteria exploring primary gold mineralization in the Attapeu area fits well with the mineral exploration group III. To estimate the ore reserve in category 112 significantly requires conducting the parallel exploration grid or rectangular grid with the exploration grid interval of 40 60 meters within the space of the exploration grid line between 20 to 30 meters. The .
