Abstract:

Integrated petrophysics linked with structural geology and mineralogy are powerful tools for mineral system characterisation. In this study, open-pit samples and drill core from the Osborne IOCG deposit were measured for anisotropy of magnetic susceptibility (AMS) and remanence. This study focused on the relationships between petrophysical properties and the high amplitude magnetic anomaly of the deposit.
