Ground Mag-VLF-EM
Ground Magnetics (MAG) and Very Low Frequency Electromagnetics (VLF-EM) are essential tools in identifying subsurface structures and mineralized zones. Ground MAG detects magnetic variations, often associated with minerals like magnetite, while VLF-EM highlights conductive bodies such as sulfide deposits.
-
Ground MAG: Measures variations in the Earth’s magnetic field to reveal magnetic minerals, geological structures, and lithology changes beneath the surface.
-
VLF-EM: Detects conductive zones, ideal for finding fault structures and shallow mineralized zones with electromagnetic fields.
-
Application: These surveys help geologists map structural and mineralized areas and refine targets for drilling.
GPR
Our Ground Penetrating Radar (GPR) surveys deliver high-resolution imaging of shallow subsurface layers, making it ideal for assessing depth to bedrock in till terrain and other complex environments.
-
High-Resolution Subsurface Imaging: GPR accurately maps subsurface features up to several meters deep, offering clarity on shallow bedrock interfaces and soil horizons.
-
Till Terrain Focus: Well-suited for understanding depth to bedrock in glacial till environments where traditional drilling may not be feasible.
-
Minimal Impact: GPR offers a non-invasive exploration solution, minimizing surface disturbance.
DC RES-IP
Our Direct Current Resistivity and Induced Polarization (IP) surveys provide high-resolution data to define geological units, fault structures, and mineralized zones with minimal environmental impact. These advanced surveys support accurate subsurface mapping for drill planning.
-
Detailed Subsurface Definition: DC RES-IP surveys map geological units and structures with high precision, useful for identifying faults and flat-lying ore bodies.
-
Flexible Configurations: Configurations can capture high-angled structures or flat-lying bedrock, maximizing data accuracy for diverse geological settings.
-
Eco-Friendly Approach: Using non-invasive geophysical technology to map subsurface structures efficiently minimizes surface impact.
