Mineral Exploration Application Iris Instruments

For mining exploration applications, the method and equipment to use depend on how the precious metal is concentrated or disseminated in rocks, on the size of the orebody but also on its depth.When precious metal is concentrated in a dyke, the detection may be performed by resistivity profiling using the promis 10 slingram type em profiler or the t-vlf to image resistivity or the syscal range.
