Title: New generation of helicopter time domain electromagnetic systems for mineral exploration in rough terrain

Date/Time: Thursday December 15, 2016 @ 4:30pm

Location: 4th Floor Conference Room, Room 451, 409 Granville St. (UK Building at Granville and Hastings), Vancouver

Abstract:
Advances in technology for helicopter borne Time Domain Electro-Magnetic survey systems in the last 10 years has allowed the Mining industry the ability to acquire high resolution data in areas historically very difficult to access.

This presentation will focus on some of the past and ongoing technical challenges associated with survey design, drape mode versus contour mode flying, helicopter and pilot performance, technical limitations of past helicopter AEM systems and data quality issues of previous public domain BC AEM surveys.

It will show examples of past system geometry and design, claimed system dipole moments and calculations of Effective Dipole Moments (EDM), based on the wave forms of the different commercial AEM systems, and realistic depth of investigation.

It concludes with details of the new SkyTEM AEM systems for providing high resolution data in these challenging areas and recent case study of a new generation system flying in British Columbia.
