Airborne Geophysical Surveys PDF

Geotech Ltd. provides full service contract airborne geophysical surveys, data processing and data interpretation. At the present time Geotech Ltd. offers VTEM (helicopter-borne time-domain electromagnetic), ZTEM and AirMt (measure natural alternating magnetic fields in the audio-frequency range), magnetic, magnetic gradient and gamma-ray spectrometer surveys.

Geotech Ltd. operates nine VTEM systems in North America of the world-wide total of 30. Our clients are mainly from the mineral and petroleum exploration industries. Our proprietary, large dipole moment VTEM system, in the six years since its first commercial survey, has become the airborne system of choice by the exploration community. A number of exploration successes have been attributed to VTEM surveys by the exploration companies. Read testimonials

Geotechs managerial staff are experienced geophysicists, electronics engineers and managers who understand the business of airborne surveying and the needs of its clients.

Geotech funds a large Research and Development effort to maintain its technological lead in its core airborne electromagnetic technologies.

Geoscience BC Releases new Analysis of the QUEST Geochemical Dataset, Z-TEM Data from Mt. Milligan and Preliminary QUEST Project Area Till Geochemistry

"... Geoscience BC is also pleased to announce the release of Geoscience BC Report 2009-7: "Helicopter-Borne Z-Axis Tipper Electromagnetic (ZTEM) and Aeromagnetic Geophysical Survey -- Mt. Milligan Test Block." The release includes a final report for the project, databases and grids, and maps in PDF format, all of which will be available from Geoscience BC's website. Z-TEM is a passive airborne electromagnetic system. It uses the natural time varying changes in the earth's magnetic field to detect conductors, map geology and explore for large poorly conductive features such as regional faults and porphyry copper deposits. Geoscience BC and Terrane Metals Corp partnered on the Z-TEM survey of the Mt Milligan property, which was flown at a 250 m line spacing by Geotech Ltd."
