Viaroc Resources employs a comprehensive suite of geophysical survey methods to accurately characterize subsurface geology and identify viable mineral deposits across our operational regions.
01
Seismic Refraction
Measuring: Mechanical response of rock and rock masses
Involves the generation and transmission of sound waves into the subsurface
Sound waves are refracted or reflected at the interface between rocks with different physical properties
Identifies rocks that contain different fluid types
Provides detailed subsurface velocity models
02
Magnetic Survey
Measuring: Identify mineralization based on magnetic signatures
Magnetic readings made with special equipment
Logs the relative strength of the magnetic field at various points
Data stored in a computer for advanced analysis
Effective for identifying iron-bearing mineral deposits
03
Gravity Survey
Measuring: Density
Use of precise instruments to measure the strength of gravity at various locations
Most effective for: diamonds, rare minerals
Detects density contrasts between geological formations
Ideal for mapping subsurface structures
04
Magnetotellurics (MT)
Measuring: Resistivity as a function of depth
Use of natural electromagnetic signals
Images subsurface electrical conductivity structure
Works through electromagnetic induction
Effective for deep crustal investigations
05
Electrical Resistivity Tomography (ERT)
Measuring: Material properties & resistivity
Ground Penetrating Radar (GPR): emission of electromagnetic waves to characterize material properties based on reflected EM signal
Ground Resistivity Mapping (GRM): use of electrodes embedded or integrated on the ground
Provides high-resolution subsurface imaging
Effective for environmental and engineering applications
06
Induced Polarization (IP)
Measuring: Chargeability of the ground
IP measurements acquired using four-electrode geometry
Conventionally used for electrical resistivity surveys
IP surveys typically employ nonpolarizing electrodes
Excellent for detecting sulfide mineral deposits
