Agnico Eagle–École Mine (Joubi)

Canada

AeroVisionTM Magnetics

 

We present the results of an AeroVisionTM UAV magnetic survey flown over Agnico Eagle’s École Mine (Joubi) property near Val-d’Or, Quebec. The 77-km survey was conducted in December 2017, using Devbrio’s onboard Collision Avoidance System, which allows the UAV to fly safely at lower altitude.

The area had been previously flown with a helicopter-towed magnetic system.

Heliborne survey:

Average altitude: 156m; standard deviation: 63m; average sample interval: 7m.

AeroVision survey:

Average altitude: 30m; standard deviation: 0.7m; average sample interval: 1m.

 

The improved resolution of the drone-towed system is evident in a side-by-side comparison.
