E028 Borehole Resistivity Tomography for Mineral Exploration W. Qian* (Geoserve Logging & Tomography) SUMMARY This paper focuses on the use of cross-borehole electric methods in ore body delineation. A BRT (Borehole Resistivity Tomography) test survey has been conducted to map massive and semi-massive sulfide zones between boreholes up to 180 m apart. The boreholes need to be water filled so as the electrode array couples to the rock formation. We have established a multi-step procedure for data acquisition processing and interpretation. Between boreholes we have successfully imaged the massive sulfide mineralization in a moderately conductive host. EAGE 69 th Conference
