IPEx: A lower-cost superior reconnaissance RES/IP/MT survey

Abstract

Summary This paper presents a technique derived from the full MIMDAS RES/IP/MT survey called IPEx. It offers a more cost-effective, enhanced reconnaissance IP investigation in areas of post-mineral cover, ensuring that a minimumsized predefined chargeable body would not be missed. The MIMDAS system is ideal for its capability to measure very low signals, due to the enhanced telluric correction, especially in caliche-covered areas. A total of four lines were surveyed with IPEx, and substantial anomalies were found, where some in-fill/detailing has been executed. IPEx takes approximately half to two thirds of the normal MIMDAS survey time, making it a lower-cost superior reconnaissance RES/IP/MT survey tool.
