MAGNETICSAEROQUEST OPERATES TWO HELICOPTER-BORNE MAGNETOMETER SYSTEMS. The first is thetri-axial magnetic gradiometer system (TAG) whichemploys high resolution optically-pumped magneticsensors with unique 3D sensor geometry for more detail and definition in gold and other mineralexploration surveys. The second system is a stinger-mounted magnetometer system whichemploys the same high resolution magnetic sensormounted on a boom. The stinger system is bestsuited for ultra-high resolution surveys in moderate to challenging terrain. Surveys can be flown with aline spacing as tight as 20 m and with a sensor heightof less than 10 m.Advantages of TAG> More accurate target positioning> Good performance in challenging terrain> Detailed definition of structure and small sources> Enhanced definition of complex structures> Actual gradients for improved cross-line griddingAdvantages of Stinger> Stable platform for low noise recording> Highest available airborne spatial resolution> Lightweight for flying in rugged and mountainousterrain> Compensation of mag data to monitor and removeplatform-induced noise> Accurate topographic drape flying> High data sampling rateCommon ApplicationsThe AeroMAG systems can be flown for a variety ofapplications, such as gold and other precious metals,diamond exploration, geological mapping andburied object detection.Advanced Helicopter-borne MagnetometersMAGNETICSAdvanced Helicopter-borne MagnetometersAeroquest International7687 Bath Road, Mississauga ON L4T3T1Phone +905 672 9129Toll free +866 693 9129Fax +905 672 7083Email sales@aeroquest.caWeb site www.aeroquest.caCalgary +1 403 450 9621Vancouver +1 604 676 9648Pretoria +27 12 332 3320Perth +61 8 9479 4232The AEROQUEST International Group of CompaniesTri-Axial Gradiometer System Stinger SystemMagnetometer: 4 separate Geometrics 823A Sensors Geometrics 823A SensorResolution: 0.001 nTSensitivity: 0.004 nT/vHzAccuracy: +/- 0.1 nTCompensation: Microstrain 3DM-GX1 Pico Envirotec MMS-4 ProcesorTracking Video: Composite video (MPEG2 format)Wide angle lens with Plextor MPEG4converter with time overlayGPS Navigation: WAAS-Enabled real-time differential with better than 1 m accuracyBase Station: Geometrics G823A high-sensitivity Cesium sensor (.001 nT) sampled @ 1 HzTow cable: 30 m NoneOperation: Operator in Helicopter No operator, pilot-only
