Nah, geophysics doesn't read ppm gold at all and the high magnetite content (~10%) will mask almost everything.

That Ema image is airborne radiometric data which maps broad-scale alteration and lithology by reading radioactive decay, etc. from micas, feldspar, etc in the soil and any outcrop so it might read sericites and clays in the porphyry and biotite alteration in the dolerite.

BBX is focussed on the metallurgical aspects of the project at the moment so they're not very forthcoming with geological data, interps, etc. The info on the website needs an update.
