Mechanism of formation of mobile metal ion anomalies

Summary

Mobile Metal Ion (MMI) responses were demonstrated on soil samples from sponsors’ sites, and showed subtle anomalies in active depositional environments where conventional geochemical methods had failed.

The MMI anomalies are sharp and located vertically above and/or on the up-dip projection of mineralisation vapor sampling, and simulated rain water leaches indicate that movement of MMI is very recent and is independent of the soil system.
