EXPLORATION TRENDS & DEVELOPMENTS
Airborne Geophysical Surveying EON Geosciences flew several large aeromagnetic and gamma-ray spectrometric surveys in Quebec for the Ministry of Energy and Natural Resources (MERN) and in United States for the United States Geological Survey (USGS), as well as a horizontal gradient aeromagnetic survey in Manitoba for a private mining company. EON signed a contract with the Geological Survey of Norway for a large aeromagnetic, gamma-ray spectrometric, and VLF-EM survey in Norway to be flown in 2021. Expert Geophysics, an airborne geophysical survey company based in Newmarket, Ont., reported an active year with MobileMT, its helicopter-borne EM and magnetic technology. Using natural EM fields in the frequency range 25 Hz - 20,000 Hz, the MobileMT system uses the latest advances in electronics, airborne system design, and signal processing techniques. MobileMT surveys were flown in North and South America and Asia, to explore for gold, porphyry copper, silver, and uranium. Four MobileMT systems are available for worldwide commercial operations and data processing, data inversion, and interpretation services including resistivity-depth. Geosphair Aviation, based in Montreal, specializes in airborne survey platform operation, management, R&D and survey-aircraft modifications. Geosphair offers aircraft management services including pilots, maintenance, survey modifications and compliance with airworthiness regulations. The company’s R&D continued to improve its Seaplane platform, working on stability-at-sea and various aids to seaplane pilot decisions. Aurora, Ont.-based Geotech, along with its subsidiaries Geotech Airborne (Johanesburg, SA) and UTS Geophysics (Perth, WA) offer worldwide airborne geophysical surveys and consulting services using its VTEM helicopter time-domain EM and ZTEM natural field EM systems and fixed-wing and helicopter magnetic, radiometric and gravity systems. In 2020, surveys included completion of a two-year, 450,000 line-km fixed-wing magnetic and gamma-ray spectrometric survey in Cameroon. The project, for World-Bank funded PRECASEM (Projet de REnforcement des CApacités dans le SEcteur Minier), included a training component. VTEM and magnetic surveys were completed for Natural Resources Canada (NRCan) for n NRG Exploration’s Xcite TDEM system in South Africa. Credits: NRG
