Ann: Aeromagnetic Survey Commences at Beasley Creek, page-44

I was curious too, so I looked up the rego. number. Testimonials on the magspec.com.au site say that the data is ‘on their desk’ about a week after the survey is flown. Terra Resources will process/interpret that data, so my guess is about 2.5 weeks, maybe longer b/c Easter, until CDT has the images. 2,323 line km @ about 100m would probably take a couple of days to fly - Magpec say their planes have 8hr ‘endurance.’ The aircraft pictured in the announcement (VH HHJ) is a Cessna 210M.

It’s an cheap way to explore + should help guide drill placement. It has taken a while but we’re here - the conglomerate gold story continues.

from wiki:
Cessna 210M Centurion / Turbo Centurion A 210L with an optional 310 hp (231 kW) TSIO-520-R engine and minor changes, produced 1977-80, 1381 built.
