Abstract

Exploration is every activity that happens before the mining activity happens, it has purposes to know, predict and obtain the dimension in quality and quantity from a reserve that has economic value. From surveying at bukit Nunggal, Mesu Village, Pangkalan Baru Sub-district, Bangka Tengah District showed that there are outcrops that indicate the potential for becoming a reserve for granite. Measurement is done to know the resource estimation and it is done by an approach of geomagnetic method that is environment friendly. The geomagnetic method is passive (to measure the magnetism level or susceptibility) from the measuring point. The total of the line to know the dispersion pattern and the depth of the resource is 13 lines with the space between measurement is 10m. From the geomagnetic measurement obtained the IGRF value is 42969, inclined degree 0.424 declined degree – 21.157, susceptibility value in between -54.2nT to 56.1 nT, and the granite susceptibility value is in between 21 nT to 50nT. The anomalies map showed that there is a resource potential, and the resource dispersion is from east to west. Viewed from the topography and the residential areas, the mining activity is recommended to be done in the west area.

Keyphrases: Geomagnetic, Granite, outcrop, susceptibility
