What Geotech does

Geotech Ltd. is a Canadian airborne geophysical survey company founded in 1982 and headquartered in Aurora, Ontario, with 101-250 employees. The company provides technological solutions for airborne geophysical survey mapping, interpretation, and analysis, serving mining companies, government geological surveys, and exploration firms across more than 50 countries. Its core product portfolio centers on two proprietary electromagnetic systems: VTEM™ (Versatile Time Domain Electromagnetic), a helicopter-borne time-domain system with concentric loop configuration for high-resolution near-surface exploration, and ZTEM™ (Z-Axis Tipper Electromagnetic), an airborne AFMAG technology that uses natural electromagnetic fields from global thunderstorm activity to map deep resistivity structures at depths of 600m to 2km. Supporting capabilities include helicopter and fixed-wing magnetic surveys, radiometrics, gravity surveys using GT-2A meters, and the newer AirMt (Airborne Magnetic Tensor) System. VTEM variants such as Full Waveform VTEM, VTEM ET, and VTEM Plus with Horizontal Magnetic Gradiometer (HGRAD) provide differentiated sensor capabilities for specific survey conditions.

Geotech operates a project-based B2B services model, contracting directly with clients on a quote basis with no public pricing, and revenue is generated through survey contracts, data acquisition, processing, and interpretation services. The company is vertically integrated through wholly-owned subsidiaries UTS Geophysics (Australian survey operations) and Geophex Ltd. (geophysical instrumentation R&D and manufacturing in Ottawa), plus sister company Geotech Aviation, which operates a fleet of more than 20 aircraft including AS350B3 helicopters and Cessna 208B Grand Caravan fixed-wing platforms. Customer acquisition is sales-led through direct engagement and presence at major industry events including PDAC, AME Roundup, Mining Indaba, and Africa Downunder. Named customers span major mining companies (Barrick Gold), junior explorers (Mustang Minerals, CanAlaska, Quantum Minerals, Athos Metals), and government geological agencies (U.S. Geological Survey, Yukon Government, Burkina Faso Ministry of Mines and Energy). Primary customer segments are mining and exploration companies and government geological surveys, with secondary use cases in oil and gas, groundwater management, and geothermal energy assessment.
