Exploration for massive sulfides is carried out at shallow depths (a few hundred meters or less) using IP or TDEM surveys. At greater depths, the only electromagnetic technique available is that of AMT or CSAMT.
Over the past decade improvements in acquisition hardware, processing algorithms and interpretation software have lead to increased reliability and almost an order of magnitude reduction in cost.
These have made the AMT method a useful tool for mineral exploration, specially in large scale frontier exploration. The method has become an effective tool for property assessment and in focusing exploration with controlled source techniques typically used in mineral exploration.
