oa The TEMPEST AEM Systëm and the Walford Creek Prospect

A new airborne electromagnetic system has been developed by the CRC for Australian<br>Mineral Exploration Technologies and is operated by World Geoscience Corporation.<br>TEMPEST operates in the “INPUT” configuration with a towed bird and a transmitter<br>located on the aircraft. It utilizes a 25 Hz square-wave transmitter with a 50% duty cycle<br>and a variable switching ramp. The system has been designed to measure a wide<br>bandwidth (25Hz - 3ZSkRz) EM response for both geological mapping and recognition<br>of conductive targets.
