I don't undertsand the point of your post, is it to suggest that Aerotem targets are no good?? If so you need do some more research and talk to a good geologist. I've been reading various posts about this crap for the last few weeks on various boards and laughing.

UC is drilling using ground geophysics which is superior to VTEM or Aerotem2 data generation. The airborne geophysics simply helps locate potential anomalies and is very useful in most conditions but especially where no or limited out cropping exists. The 100 line spacing Aerotem2 that was utilized by UC and Noront for all targets to date is an excellent product. VTEM does allow a deeper penentration though.
