 Magnetic Surveys

• • Description: Magnetic surveys measure variations in the Earth’s magnetic field caused by the underlying geology. They help in mapping geological structures, mineral exploration, and identifying subsurface anomalies.
  • Methods: Ground-based magnetometers, airborne magnetometers, and marine magnetometers.

Electromagnetic (EM) Surveys

• Description: EM surveys detect subsurface conductivity variations by inducing electromagnetic fields and measuring the response. These are useful for mineral exploration, groundwater studies, and environmental investigations.
• Methods: Very Low Frequency (VLF), Time-Domain EM (TEM), Frequency-Domain EM (FDEM), and Magnetotellurics (MT). 

Gravity and Gradiometry Surveys

• Description: These surveys measure variations in the Earth’s gravitational field caused by density differences in subsurface materials. They are used for oil and gas exploration, mineral prospecting, and geological mapping.
• Methods: Ground-based gravimeters, airborne gravity meters, and gravity gradiometers.

Seismic Surveys

• Description: Seismic surveys use the propagation of seismic waves to image the subsurface. They provide detailed information about geological structures and are essential in oil and gas exploration, mineral exploration, and engineering studies.
• Methods: Seismic reflection, seismic refraction, and passive seismic methods.

Induced Polarization (IP) and Resistivity Surveys

• Description: These surveys measure the ground’s resistivity and chargeability to identify subsurface materials. They are commonly used in mineral exploration, groundwater studies, and environmental investigations.
• Methods: Dipole-dipole, pole-dipole, and gradient array configurations.

Radiometric and Spectral Gamma Surveys

• Description: Radiometric surveys measure the natural gamma radiation from rocks and soils to identify radioactive minerals. They are used in mineral exploration and environmental studies.
• Methods: Ground-based scintillometers, airborne gamma-ray spectrometers.

Ground-Penetrating Radar (GPR) Surveys

• Description: GPR uses high-frequency radar waves to image the shallow subsurface. It is effective for detecting buried objects, voids, and changes in material properties.
• Methods: Handheld and vehicle-mounted GPR systems.

Soil and Rock Mechanics Testing

• Description: These tests determine the physical and mechanical properties of soil and rock. They are critical for construction projects, mining operations, and slope stability analysis.
• Methods: Triaxial compression tests, direct shear tests, uniaxial compression tests, and point load tests.

Slope Stability Analysis

• Description: Slope stability analysis evaluates the potential for landslides and slope failures. This is essential for open-pit mining, road cuts, and construction projects.
• Methods: Limit equilibrium methods, numerical modeling, and field monitoring.

Groundwater Modeling and Dewatering Studies

• Description: Groundwater modeling predicts the behavior of groundwater systems. Dewatering studies are conducted to design systems to manage water in mining and construction sites.
• Methods: Numerical groundwater modeling, pump tests, and hydrogeological mapping.

Geotechnical Site Investigations

• Description: Comprehensive site investigations to determine the subsurface conditions for construction and mining projects.
• Methods: Borehole drilling, cone penetration testing (CPT), standard penetration testing (SPT), and geophysical methods.

Geological Services

Field Mapping and Sampling

• Description: Detailed field mapping and sampling provide fundamental geological information about the area of interest. This helps in understanding the geological framework and mineral potential.
• Methods: Geological mapping, rock and soil sampling, structural analysis, and lithological studies.

Petrographic and Mineralogical Studies

• Description: These studies involve microscopic examination of rock samples to determine their mineral composition and texture, providing insights into the geological history and potential mineralization.
• Methods: Thin section analysis, X-ray diffraction (XRD), and scanning electron microscopy (SEM).

Geochronology

• Description: Geochronology determines the age of rocks and minerals, which is essential for understanding the timing of geological events and mineralization processes.
• Methods: Radiometric dating techniques such as U-Pb, Ar-Ar, Rb-Sr, and fission track dating.

Resource Estimation and Classification

• Description: Estimating and classifying mineral resources and reserves following international standards. This is crucial for the economic evaluation and development planning of mining projects.
• Methods: Geostatistical analysis, block modeling, and classification standards (JORC, NI 43-101, SAMREC).

Environmental and Social Impact Assessments (ESIA)

• Description: ESIAs evaluate the potential environmental and social impacts of mining projects and develop mitigation measures to minimize negative effects.
• Methods: Baseline environmental studies, impact assessments, and development of environmental management plans (EMP).

Geotechnical and Geological Consulting

• Description: Expert consulting services for various geological and geotechnical challenges encountered in mining, construction, and environmental projects.
• Methods: Site investigations, risk assessments, and development of mitigation strategies.
