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 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.

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.

Ground Cesium-Mag 50-m lines trumps Old-School-Mag done on 100-metre lines.

Many cesium magnetometer surveys are carried out without cut lines.  The onboard GPS is used for navigation and positioning.  Data are recorded at 10x per second.  Therefore, lines are spaced 50-metres apart in areas where drills are standing by.  This allows for the interpretation of 'breaks' in the mag which can act as conduits for gold and other economic mineralization.  Gone are the days where traditional 'proton precession' style magnetometers are used for serious high resolution and high quality data.  IP/resistivity survey lines can be 'targeted' to specific areas (e.g., breaks in the magnetics contours) to reduce costs by exploring more efficiently!



In the image above, airborne data show a single large magnetic high whereas the 50-m lines 10x per second ground-cesium magnetics data clearly show two magnetic highs - this gained from just 1 hour of work on the ground.

Today's technology allows for the overlay of geologic maps on the GPS and magnetics datalogger console so that various features can be viewed real-time by the operator as the survey progresses.  For example, mapped faults and shears can be seen as the survey progresses, giving the geophysicist operator an advantage when interpreting the data.

The image below is a screen-shot of the geologic maps and claim boundaries on the office computer screen. The datalogger is also seen in this image with the planned survey waypoints (cyan dots) at 50-metre intervals.


The bottom image is the datalogger in the field as data are collected.  Notice the red lines showing the lines completed and the black 'cross' showing the present location of the geophysicist operator in the field.  The '-1' shows the distance in metres that the operator is off the planned survey line.  In this case, 1 metre to the left/west.
