Indonesia has the potential for asphalt deposits, especially on Buton Island. In determining asphalt resources, the most important parameter is the accuracy of the geological model. In geomodeling, there are several criteria, including analysis of geological complexity, analysis of quality distribution, and subsurface mapping to observe the geometry of the distribution of asphalt layers resulting from drilling activities. This paper aims to produce a geomodeling of asphalt deposits. The method used is the correlation between surface mapping data and subsurface data, in the form of sixty exploration drill holes data, then a subsurface geological model is generated. The results showed that there were four layers of asphalt found, where three layers of asphalt split into two layers. The asphalt layer found has varying thickness which is influenced by the presence of weak zones and is in the form of a fluid. The distribution direction of the modeled asphalt layer and several asphalt outcrops resulting from surface mapping are known to have a known stance and layer slope, the asphalt outcrop has a strike layer of N1950 – 2350E towards Southwest – Northeast and the slope of the layer is relatively gentle, which is between 150 – 200 NW. The geological model produced can be used as a reference for mining companies in detailed planning exploration and estimating resources.
