Amira program P1245 Spectral Induced Polarisation (SIP) – completed on 11 Sept 2024 – demonstrated the promise of SIP for mineral exploration, for example with respect to identifying and distinguishing between varieties of sulphide mineralisation and/or textures. However, significant limitations in field data quality reduced its interpretive value and highlighted areas for potential improvement in survey design, execution and interpretation.
Low-frequency SIP data show particularly encouraging potential to distinguish true mineral targets from false positives, with further investigation required into methods for improving data fidelity (noise reduction), including electrode material selection/engineering, installation geometry, minimising transmitter infrastructure noise and remote reference techniques.
With traditional models failing to capture the complexity of SIP responses (e.g. distinguishing between Faradaic and non-Faradaic polarization), P1245A also aims to refine SIP modeling frameworks, along with investigating potential non-linearity effects in field data, improving interpretive accuracy and reducing ambiguity in inversion results.
