Ground Geophysical Survey
We provide non-invasive, high-resolution subsurface imaging that replaces guesswork with data-driven certainty. Our methods reduce drilling costs, mitigate site risks, and accelerate project timelines across the mining, engineering, and environmental sectors.
Magnetic Survey
Magnetic survey detect variations in the Earth’s magnetic field to map structural trends and identify magnetic mineral deposits, acting as the industry’s most cost-effective tool for regional reconnaissance.
Gravity Survey
Gravity survey identifies dense blind ore bodies and underground voids by measuring minute changes in gravitational pull, ensuring that non-magnetic targets are not overlooked.
Seismic Methods (Structural Imaging & Bedrock Analysis)
Seismic surveys provide the highest resolution of subsurface layering and are the gold standard for depth-to-bedrock and reservoir mapping.
Electromagnetic (EM) Survey
Time Domain Electromagnetic Survey pinpoints highly conductive metallic sulfide deposits (such as copper and nickel) by measuring the ground’s response to induced electrical currents.
Induced Polarization (IP)
Induced Polirazion is the premier method for locating disseminated gold and copper deposits by detecting the ground’s ability to hold an electrical charge..
Electrical Resistivity (ERT)
Electrical Resistivity maps groundwater resources and monitors the movement of environmental contaminants by measuring how different materials resist electrical flow.
