Gold Mining Underground

Robertson Geo successful in logging multiple inclined bore holes in difficult space and application positioning.

Using a High Resolution Acoustic Televiewer (HRAT) to log data to assist management with mineralisation modelling, development planning and extraction projections; the application was used to identify and characterise stacked veins, fault breccia, mineralisation zones, foliation characteristics, secondary micro faults, fractures and fault patterns. It required nine boreholes to be logged during site visits staged over three months. The boreholes were 400 through 500m deep and typically inclined at 35 to 45 degrees, core drilled with an OD of 76mm.
