Andesite is a mining commodity that is currently very prospective for business. This relates to the number of andesite needs used for infrastructure. To find out the condition of a prospect area for mining, it is necessary to identify the resource, one method to estimate the resource is to use a resistivity 2D geoelectric. In this research, the calculation of andesite resources was calculated in the Kaliglagah area, Loano district. Data was collected using 2D and IP resistivity methods of Schlumberger N9 configuration using Naniura NRD 300 device. This measurement will provide the measurement results in the form of a cross-section of resistivity. Measurements were carried out with 4 lines: each with a length of 310 m with a maximum depth of 60 m. The total volume of calculations for Andesite was 778,625 m3, Weathered Andesite was 160,875 m3, Overburden was 678,875 m3 and Top Soil was 447,625 m3. But considering the results of this calculation are inferred resources, the confidence level is 80% so that if the total volume is multiplied by 80% and the total number of Andesite resources is 622,900 m3, Weathered Andesite is 128,700 m3, Overburden is 543,100 m3 and Top Soil is 358,100 m3.
