The Next Generation of Heli-TDEM and the co-collection of TDEM, LiDAR, Magnetics and Radiometrics.

Helicopter based Time Domain Electromagnetics has proven to be a useful exploration method in targeting a wide range of ore systems for decades. The ability to collect high resolution data in short periods of time and low costs makes this a preferred method for larger areas across the industry. New technologies and construction methods developed in this field are resulting in increased resolution and decreased noise bringing better value to customers. The Xcite™ TDEM system powered by NRG and provided in Canada by Axiom Exploration Group LTD. offers state of the art inflatable construction and industry leading technology which push the limits of modern airborne TDEM systems. Real world examples of the Xcite™ data are shown over several commodity types as well as comparisons with other industry competitors. The co-collection of LiDAR, magnetics and radiometrics, has proven to be extremely effective in bringing multiple valuable products to clients across several projects to date.

Chris acquired a B.Sc. (Hons.) in Earth Sciences, focusing on geophysics, from Memorial University of Newfoundland in 2006. Since then, he has been applying borehole, ground and airborne geophysical methods to enhance mineral exploration projects in a wide range of environments globally. He has been involved in many aspects of geophysical project management from business development, client retention and budgeting, to survey planning, data acquisition, processing, modelling and interpretation. He has interpreted datasets for myriad mineral deposit types including magmatic Ni-Cu-PGEs, porphyry Cu, Pb-Zn-Ag, vein-hosted and placer Au, BIFs, REEs, U, VMS, graphite and diamonds. His work has taken him all over Canada, the United States, Mexico, Norway, Ethiopia, the Democratic Republic of Congo, Fiji and Italy.
