With the proliferation of battery-powered technology, such as cell phones, laptops, and electric cars, the need for graphite is expected to increase as it plays a crucial role in batteries and fuel cells. We present the IMAGEM system, a high-resolution ground-based time-domain electromagnetic system, whose high spatial resolution allows it to accurately delineate small deposits, on the order of a few metres thick. We perform forward modelling and inversion using a 1D modelling software program, AarhusInv, and present the results of case studies where the system was used for graphite exploration. The IMAGEM system was able to differentiate multiple distinct anomalies where the classic MaxMin system could only outline one anomaly. The IMAGEM system is still being developed and shows great potential for detecting small near-surface bodies, such as graphite deposits. AarhusInv proves to be an effective program to model the IMAGEM system.
