Loupe is a portable, time-domain EM system specifically designed for rapid reconnaissance and near-surface conductivity measurementsTo date the range of applications has included mapping seepage from tailings dams, mapping acid drainage from mine dumps, mapping combustible shale horizons in iron ore mines, detecting voids, mapping of sulphide ore near to surface, and routine exploration for base metals, diamonds, graphite, manganese, and gold. Other applications of benefit to the wider community are foreseen in the future, including mapping of potential groundwater aquifers or groundwater contamination, civil engineering studies, and archaeological mapping.Loupe is designed to be used in continuous profiling mode at walking pace.
