- Exploration activities can not be separated from the measurement of geomagnetic method. Geomagnetic method is one of geophysical method that is often used and does not require big cost in exploration activity of tin. The use of geomagnetic method tools is very effective to reach a wide scale with a variety of measurement site terrain as well as data measurements of geomagnetic method can help analyze the state of the subsurface. Overview of the Earth's surface measurements of geomagnetic methods depends on the determination of point spacing measurement. Spacing point measurement geomagnetic methods typically use spacing of 20 meter. Determination of spacing of measurement points need to be tested using the comparison of spacing of 10 meter, 30 meter, 40 meter, and 50 meter with geostatistic approach (kriging). The measurement data of geomagnetic method used is Total Magnetic Intensity (TMI) value. The result of the geostatistical approach to the geomagnetic point spacing measurement point is expected to provide an alternative use of effective measurement point spacing in the exploration activities. The 40 meter spacing between geomagnetic measurement points shows a pattern that its almost the same as a 10 meter spacing with a level of confidence (r) that its higher than spacing of the confidence with 0.529 value.
