Abstract

As part of the exploration program near the Syama mine in Mali, a 3D resistivity and IP survey was designed for detailed lithological mapping of a partially drilled deposit, about 30 km along strike from the main orebody. Tight line spacing and offsets between transmitting and receiving lines ensured 3D coverage. The survey design had to accommodate simultaneous drilling activity on nearby lines. The combination of resistivity and chargeability measurements map distinct basalt, chert, and graphite lithologies. After 3D inversion, constrained by the available drilling information, the data show structures and folds that will influence resource models.
