n ORION 3D survey, covering an area of 4 sq km, can be completed in only 3 weeks and provides the most sophisticated electrical imaging of the subsurface possible. There are virtually no limitations to the configuration of an ORION 3D survey. A survey covering an area of roughly 2 km x 2 km will provide deep 3D information to a depth of 2 km. What is ORION 3D ? ORION is a highly flexible 3D ground geophysical survey that can mobilise anywhere, is unlimited by terrain and other surface conditions, and is perfectly suited to explore in sensitive areas. ORION 3D collects three sets of data in multi-directions – DC Resistivity, IP (induced polarization) to depths of 800 m, and deep MT resistivity to depths greater than 2000 metres. ORION 3D is the leading REAL 3D ground geophysical survey. The design of the survey allows for complete omni-directional coupling with geology, structure and mineral systems in the subsurface. This ability to measure in all possible directions means the system provides information on all possible orientations of subsurface structure and mineralisation. 3D surveys have no imaging bias imposed by survey geometry as can occur with traditional 2D. Quantec’s ORION 3D technology collects data along multiple lines and in multiple directions. The system collects more than 200,000 data points per survey. With more data and omni directional data the derived 3D images offer thorough exploration prior to drilling. ORION 3D uses core features developed through the evolution of the TITAN 24 system. Full time series data acquisition for processing optimisation and noise cancellation All transmitter signal is recorded and subsequently exactly removed from the recorded data (does not occur in traditional acquisition routines) Telluric cancellation available for IP
