This has been a marginal sleeper that now has nearby potential. It has always been undervalued IMO.

PP I followed your posts and luckily logic RE CDU. I am not a geologist but the 'hollow core' VTEM anomalies are what you expect from steeply dipping conductor. This is because when the VTEM system is over the top of a steeply dipping conductor it's transmitted EM field is not coupled to the conductor like it is when it is slightly offset to it, hence the relative low amplitudes in the centre of the anomalies. A relatively flat lying IOCG type conductor would have relatively uniform amplitudes, assuming homogenous electrical properties. Hope this helps.
