1634: Mapping near mine geology with advanced Geophysical technology
Authors: Roger Sharpe, Robert Hearst & Robert Gordon | Presenter: Robert Gordon


Find out why ORION 3D is the industry standard for deep accurate structural mapping and target delineation.

ORION 3D provides REAL 3D data acquisition which translates to REAL 3D data models.


Quantec will be at the Saskatchewan Open House

Please visit Quantec at our booth at the Saskatchewan Geological Open House Nov 27,28 and 29. Both Rob Gordon and Roger Sharpe will be in attendance to answer questions about our services and provide ideas for your exploration plans.

The Orion3D technology was first initiated in 2006 and trialed in 2007. The first commercial implementation was 2011.

Orion3D is the first ever distributed acquisition system (DAS) -based full 3D data acquisition system that includes both IP and MT.

There are several unique features of the system including a large footprint of 2 x 2 km to optimize DC and IP depth of investigation in the 500 m to 800 m depth range; and an ostensibly equal number of in-line and cross-line receiver dipoles that maximizes coupling with an target.

Survey results will be shown from a number of exploration situations globally including epithermal gold, IOCG and a copper-gold porphyry system. Case studies reveal the advantage, of true 3D vs 2D or 2.5D acquisition. True 3D is defined to mean acquisition where receiver electrodes sample the current in orthogonal directions and a large number of receivers (300) are deployed (using a DAS) to optimize the footprint geometry. For every current injection, all receivers are active. This results in a true omnidirectional coverage for each current injection and gives multiple intersecting current paths over the entire survey with a very large number data points acquired. The result is greater coupling with complicated 3D geology and structure which enhances resolution and target detection at both shallow and deep depths.  The omnidirectional coverage provides a better 3D inversion result because there is no acquisition directional bias and each cell in the inversion volume is sensitive to multiple omnidirectional current paths.

Examples which show this increased definition through a high correlation with drill results from actual field surveys will be discussed following a brief description of the technology.
