As a leading geophysical company in Kazakhstan, we are excited to introduce vector measurement technology for induced polarization during this field season. The recent field trials conducted at the promising Besshoky ore target have yielded positive results. The implementation of this advanced technology expands our range of applied techniques, enhancing the efficiency of geophysical studies in mineral exploration operations.

In the Vector IP survey, the electrical properties are measured in two perpendicular directions, typically along the X and Y axes from a dipole source.
The measured values are utilized to calculate the chargeability vector and the electrical resistivity vector. This technique proves effective in the presence of complex geological structures and mineralization zones with isometric shapes.
The test survey on vector measurements was performed over the well-known ore deposit of the Besshoky area. The objectives of the project were to develop a best practice of observation and data processing, along with an assessment of economic indicators (determination of the performance of operation).
The observation points were located in a Kennecott checkerboard pattern with an average distance of 300 meters between them. The minimum distance of the receiving electrodes to the nearest current injection electrode was 300m.
As a result of the measurements, a conducting zone was identified in the central part of the survey area, along with an area of increased chargeability in the northeast part.
Additionally, an analysis of the temporal characteristics of the IP decay was performed. The selection of a two-component Cole-Cole model has been completed. The zone with increased chargeability is more pronounced in the second component with a larger time constant, which is typical for ore dissemination.
A detailed survey covering an area of 1,5 km² has been completed within half of a work shift. The operating results demonstrate a good correlation between the anomaly and a known ore deposit.
The completed works have confirmed the effectiveness of using vector measurement technology and the readiness of Aurora Geophysics Limited to apply the technology to objects of any level of complexity in geological structures.
