Magnetic surveys

Exploration Service offers a full range of ground magnetic survey services, being one of the industry leaders in field operations and geophysical data processing.

The method is based on the study of inhomogeneities in the Earth’s magnetic field caused by variations in the magnetic susceptibility of rocks and is a key tool for geological mapping, mineral exploration, and studying deep geological structures.

Surveys are carried out through high-precision measurements of the total magnetic field intensity and/or its components within defined profiles or areas. The high mobility and productivity of ground surveys allow for rapid detection of magnetic anomalies associated with intrusive bodies, metasomatic zones, banded iron formations, and other magnetically active targets.

The method is widely used for structural mapping, fault tracing, and estimating the depth of geological objects. All data undergo comprehensive processing, including correction for magnetic field variations, enabling the creation of detailed anomaly maps and reliable geological interpretation.

Quality control and real-time data processing

Exploration Service provides a full cycle of data processing using professional software Oasis Montaj. Our key advantage is a team of QA/QC and data processing experts who support the project in real time. This allows us to:

promptly identify and eliminate potential errors in field data
monitor survey completeness and quality
accelerate the interpretation process and decision-making

This approach ensures high-quality final results and reduces risks at all stages of geological exploration projects.

For tasks requiring maximum detail, Exploration Service conducts walking magnetic surveys with minimal station spacing.

This method enables the detection of low-contrast anomalies and local structures that are not identified in less detailed surveys. It is particularly effective for gold exploration associated with magnetite, mapping hydrothermal alteration zones, refining geological boundaries, and identifying small-scale structures.

The result is high-precision maps that support informed decision-making at the drilling and subsequent exploration stages.

Modern quantum magnetometers based on the Overhauser effect are used, including systems such as GEM Systems GSM-19, providing ultra-high sensitivity, minimal drift, and stable measurements across a wide range of conditions.

Integration of GPS modules ensures precise positioning of each measurement point in real time, which is critical for subsequent data processing and interpretation.
