What Géophysique TMC does

Géophysique TMC is a privately-held, family-owned geophysical field-data-collection firm headquartered in Val-d'Or, Quebec, founded in 1998 by co-owners Gabriel and Simon McCrory. The company provides ground and drone-based geophysical survey services to mining and mineral exploration clients, covering eleven measurement methods (magnetic, induced polarization including downhole, gravimetry, surface and borehole TDEM, magnetotellurics/HSAMT, HLEM, VLF, lake-bottom sediment sampling, and seismic) plus adjacent services such as exploration camp construction, line cutting, topographic surveys, and senior-geophysicist-led interpretation and drilling-target recommendations.

Its core technology stack is built around crew-deployed instrumentation with proprietary AIM LOW™ active altitude-control and collision-avoidance logic enabling UAV-based cesium magnetometer surveys as low as 3m above treetops. Final deliverables are processed using third-party industry software (Geosoft Oasis Montaj® and Geotomo RES2DINV®) and exported in standard GIS/CAD formats (ArcView, AutoCAD, GeoTIFF, MapInfo, PDF). The business sells project-based professional services—priced per quote with no disclosed list rates—through a direct enterprise sales motion to mining clients. The firm operates from three legal entities spanning Canada, Mexico (since 2006) and the United States (Nogales, Arizona), and its project portfolio spans 15+ countries across North America, South America, the Caribbean, Europe, Africa and Asia.

Core offering

Géophysique TMC provides professional field data collection services for mineral exploration, delivering ground geophysical surveys (magnetic, induced polarization, gravimetry, surface and borehole TDEM, magnetotellurics, HLEM, VLF, and seismic), drone-based magnetic surveys using proprietary AIM LOW™ altitude-control technology, and complementary services such as exploration camp construction, line cutting, topographic surveys, and interpreted drilling-target reports.

Product overview

Géophysique TMC is a geophysical field data collection company headquartered in Val-d'Or, Abitibi since 1998, with a division in Mazatlán, Mexico (opened 2006). The company operates three interconnected service lines: Ground Geophysical Surveys (the core offering, covering eleven geophysical methods including magnetic, induced polarization, gravimetry, TDEM, magnetotellurics, HLEM, VLF, lake-bottom sediment sampling, and seismic), Drone Magnetic Survey Services (using a cesium magnetometer UAV with AIM LOW(TM) altitude control technology), and Additional/Adjacent Services (exploration camp construction, line cutting, topographic surveys, HR management, report writing, drilling targets, and interpreted maps). Data is processed using Geosoft Oasis Montaj® and Geotomo RES2DINV® software, with exports available in ARCVIEW, AUTOCAD, JPEG, GEOTIFF, MAPINFO, and PDF formats.

Direct peers

• Crone Geophysics and Exploration Ltd: Canadian provider of ground and borehole EM, magnetic and IP surveys for mineral exploration. Already a formal technology partner of TMC, making it the most directly comparable peer in method-mix and customer base.
• SJ Geophysics Ltd: Specialist in ground and borehole geophysics for mining exploration (TDEM, CSAMT, MT, IP, gravity). Closely comparable niche, customer base and method stack to TMC's ground survey offering.
• Discovery Geophysics International: Mining-focused ground and airborne geophysical survey contractor serving similar junior and major mining clients in the Americas. Comparable service model and target customer segment to TMC.
• Zonge International: US-based geophysical services firm offering ground IP, CSAMT/MT, TEM and gravity surveys primarily for mineral exploration. Overlaps directly with TMC's method stack and end markets.
• SkyTEM Surveys: Provider of airborne (drone and helicopter) EM surveys for mineral exploration and groundwater. Comparable to TMC where drone-based acquisition is concerned, representing both a peer and a partial substitute.
• Sander Geophysics: Airborne magnetic and radiometric survey provider serving global mineral exploration clients. Competes for the same exploration budgets as TMC, but from an airborne rather than ground-based delivery model.
• Geotech Ltd: Canadian airborne geophysical survey company (VTEM, magnetic, radiometric) serving mineral exploration clients globally. Comparable customer base and exploration-budget overlap with TMC.

Regional players

• Southern Geoscience Consultants: Australia-based geophysical consulting and survey services firm for mineral exploration. Highly comparable service offering but primarily serves the Australian/APAC market rather than the Americas-focused footprint of TMC.

Broad incumbents

• CGG: Large geoscience group historically focused on oil & gas subsurface imaging but actively expanding into mining and critical-minerals geophysics. Represents the broad-incumbent competitive threat to specialist firms like TMC.
• Fugro: Global site characterization and geoscience services firm that increasingly serves mining and infrastructure clients. Represents a much larger broad-incumbent peer that can compete for integrated exploration-geophysics scopes.
