Spectral IP and Resistivity

Spectral Induced Polarization & Resistivity surveys (IP & Res) are excellent methods for detecting disseminated sulphide mineralization that could be associated with gold. The surveys are carried out using surface and borehole modes.

Large Loop TDEM

ClearView Geophysics Inc. owns and operates transient PROTEM receivers and TEM57/67 transmitters built by Geonics. This system has proven itself useful for detecting both good and bad conductor sulphide mineralization located both shallow and 100’s of metres deep. It is also useful for detecting sources of water.

Snowmobile-Mode Cesium Magnetics

Cesium magnetometer surveys are carried out using a custom-built sleigh pulled behind a standard snowmobile. This system has proven itself on numerous large-scale mineral exploration projects during the past 15+ years.

Seismic Refraction

Seismic Refraction surveys are typically carried out for depth to bedrock investigations. The "shot" can be either an explosive or hammer source. Interpex IXRefraX software is used to process the data.

Electromagnetic (EM) and Magnetic surveys

EM and Magnetic surveys are perhaps the most common geophysical methods used on mineral exploration and environmental investigations. The most commonly used EM instruments for environmental investigations are the Geonics EM31 and EM61.

GPR ( Ground Penetrating Radar )

GPR works best in low conductivity areas. Conductive materials (e.g., clay) attenuate the GPR signal to the point that very little depth penetration is achieved. Penetration is greatest in unsaturated sands and fine gravels.

Gravity

Gravity surveys are completed for a number or applications, including mineral exploration (e.g., diamonds) and geotechnical investigations (e.g., escarpments).

Geophysical Interpretation

ClearView has extensive experience interpreting airborne and ground-based geophysical data. We use UBC's suite of inversion software to produce 2D and 3D interpretations of total field magnetics and IP/Resistivity data. Post-processing software is also used to produce various derivative datasets and maps.

Welcome to ClearView Geophysics

ClearView Geophysics Inc. is a geophysical services company founded in 1996. There is no better way to collect high resolution sub-surface data than with ground-based sensors or 'boots on the ground'. When you describe your project goals to us, we will design a geophysical survey to help you achieve those goals in the most cost-effective manner possible. Getting ground-based geophysical data is arduous - so we are constantly working to find ways to make it easier, whether its with our snowmobile- and ATV-mode surveys or with exo-skeleton systems for more supportive and safer fieldwork.

Joe Mihelcic, P.Eng., M.B.A.
Geophysicist, President & Owner

About the Owner: Mr. Mihelcic is an Applied Science '88 Geological Engineering (Geophysics Option) graduate of Queen's University at Kingston and '95 MBA graduate of Ivey Business School at the University of Western Ontario in London. He enjoys designing and implementing off-the-shelf components and technologies to make ground geophysical surveys easier and therefore more cost effective. He also writes his own software to streamline processing and interpretation.

ClearView owns IMAGEM system for TDEM surveys

The IMAGEM system is a state-of-the-art high resolution time-domain system that is capable of recording 200 channels of on- and off-time EM measurements.

Approximately 700 amps are transmitted through a single-turn and highly portable platform. This system, which is based on airborne survey designs, replaces 50-m and less inter-coil MaxMin/Promis readings. The fixed receiver and transmitter configuration provides data that are easier to interpet particularly in variable/rough topography. Readings are collected at less than 1-second intervals for much higher resolution than MaxMin or Promis surveys.

Time constants can be calculated and the data can be imported to modeling software such as Maxwell.

The IMAGEM system is in high demand for gold exploration where high precision is required. ClearView continues to apply it for walking-mode surveys and dual cesium-magnetics & electromagnetic snowmobile-mode surveys in the arctic.
