Aarhus Geophysics announces the release of a general HTEM module that allows complete advanced processing and inversion of virtually every helicopter TEM system on the market today, e.g., VTEM, AeroTEM, HeliTEM. You can now enjoy the full capability of the Aarhus Workbench software for detailed data editing, inversion to smooth and blocky models, results evaluation and display, production of final pdf maps. In true Aarhus Geophysics Aps style, the aim is to go beyond bump anomaly finding, fast approximate transforms or inversions, or any other forms of qualitative appraisal of the AEM data, and to produce quantitative results instead. The aim is to take you … from Data to Knowledge Import your AEM data in the GIS environment of the Aarhus Workbench, describing th e full System Transfer Function, and perform:

-advanced processing of navigation, altimeters and tilt metres data

-decoupling, filtering, and noise assessment of the EM data

-full non linear quasi-3D spatially constrained inversion

-constrained inversion with prior information from boreholes or other geophysics-derived layer boundary

-results evaluation, in terms of Data Residual, Model Parameter Sensitivity, Depth of Investigation

-model display, as horizontal maps in depth and/or elevation, and cross sections

-custom searches of model space and thematic maps, e.g., depth to good conductor.


2010 Frontier Exploration with airborne geophysics

The 2010 Long Range exploration program is focussed on two areas of activity, the first being the more advanced exploration on the Portage nickel discovery and the second being frontier airborne geophysics and follow-up prospecting over the newly acquired claims recently incorporated into the Long Range property. As of June 17th, 2010, the frontier airborne geophysical surveys over the newly acquired claims was completed with results anticipated to be available in August 2010.  Once received, data will be reviewed to select targets for immediate follow-up by ground prospecting. Areas surveyed by the 1,400 line kilometre Fugro HELITEM® airborne surveys include several properties underlain by unexplored gabbro bodies recently recognized to be prospective for magmatic nickel-copper sulphide deposits. Depending on results, it is hoped that the prospecting activities will help evaluate targets for further work including testing by diamond drilling.

The Long Range property, located 64 kilometres to the southwest of Buchans, covers 381,500 hectares (381.5 km2). The exploration philosophy at Long Range is centered around the potential for discovery of a magmatic nickel sulphide deposit broadly analogous to Vale Inco’s Voisey’s Bay mine in Labrador and Kennecott’s Eagle deposit currently being developed in northern Michigan

An airborne geophysical survey flown over the initial property in 2008 detected a number of anomalies in prospective gabbro. Follow up work ultimately resulted in the discovery of the Portage Nickel prospect and the Range Copper prospect highlighted below. Additional frontier exploration is ongoing to identify new prospects in this highly prospective and un-explored region of Newfoundland.
