Aquares Resistivity Surveys for Freshwater – River Crossings

Aquares Land and Freshwater data sets may be merged for a seamless view of the sub-bottom. If sufficient soundings are collected, a 3-dimensional view of the sub-bottom may be constructed. In the example below, a survey of a freshwater river system was undertaken as part of a study to quantify the gravel in a diamond bearing river. Here gravels (generally > 80 Ohm.m) are seen above the bedrock and clay stones. The accurate calculations of gravel volumes allowed the diamond reserves to be estimated.

Vertical sections are shown within a 3D voxel rendering. Gravels are located within the light green to orange colour band. After the lithologies had been defined, it was possible to calculate the volume of gravels and estimate the total diamond reserves within the lease.
