It's a good question as to how they would have MLEM targets without AEM targets. Maybe they are using other data source (mag, existing wells/sampling).

Look at CVV's announcement today for the sort of thing PUR could be up against at Wubin wrt shallow conductivity. PUR would have chosen not to release such images. They are either still trying to process the data, or it has been processed and we may have to wait for them to show MLEM conductor plates (if they exist) on either the AEM or magnetic data.

I'm not sure exactly what you are referring to with the vein running through Wubin. The image I see (might not be what you are referencing) is just magnetics (best to ignore shallow EM conductors for impact on magnetics) and doesn't extend up to Wubin.
