Objectives of Aerogeophysical Investigations
- Regional and detailed geological mapping;
- Exploration and evaluation of mineral deposits;
- Study of tectonics and deep crustal structures;
- Identification of areas prospective for mineral resource exploration and extraction;
- Engineering-geological investigations and environmental monitoring.
Advantages of Aerogeophysical Surveys:
- Coverage of large areas in a short time
- High density and integrated data sets
- Capability to survey inaccessible or hazardous areas
- More cost-effective compared to many ground methods
- Production of digital models and 3D maps for advanced analysis
- Compatibility with GIS and satellite data for enhanced interpretation
EQUATOR Complex
The EQUATOR complex is designed for airborne geophysical surveying and supports a wide range of geological and exploration tasks. It includes:
- Airborne electrical prospecting system using transient process methods
- Aeromagnetic system
- Aero-gamma spectrometer (NaI(Tl) 48 l, energy resolution 8% @ 0.662 MeV)
- High-precision navigation and data acquisition systems
- Automatic processing software for airborne geophysical data

Bainazar Integrated Airborne Survey
Comprehensive aeromagnetic and aero-gamma spectrometric survey in the Karaganda region covering 4,008 line km at 1:10,000 scale. Flights were conducted with terrain-following at an average flight height of 72 m.
Results included maps of magnetic and radiometric anomalies and a digital database of magnetometric and radiometric data for further exploration

Staropyatigorskoye and Yuzhnoye Prospect Airborne Survey
In 2024, low-altitude aeromagnetic survey with UAV was conducted over an area of 11.5 km² at 1:10,000 scale, with 126 line km of profiles. Prior to the survey, aerial photography was carried out and a digital terrain model constructed.
The project produced numerical datasets and anomalous magnetic field maps, 3D geomagnetic models, and interpreted structural zones recommended for follow-up exploration for Cu, Pb and Au.

Advanced Airborne Survey in the Mangystau Region
2021–2023: Regional-scale airborne geophysical works were completed to establish a geophysical basis for GHK-200, GDP-200 and GGK-200 programs.
This included magnetic, gamma-spectrometric and ground gravimetric surveys, generating interpreted data and identification of priority targets for further mineral and hydrocarbon exploration.
