Hi Impecunious. Portable XRF data for gold contained within another medium - i.e. rock, drill core, drill chippings, soils is highly unreliable due to a combination of what is described as the 'nugget effect' (the tendency for gold to occur as discrete grains - always irregularly distributed) and subsampling error (the sub-sample selected for analysis may not be representative of the whole sample). The presentation was actually very typical of a decent 'conference-style' presentation that could be made at an exploration conference, so I wouldn't knock it too much. Positive aspects are 1. the 20 km long fault structure, 2. the high-grade ore shoots are 'big, thick, high-grade' and 3. the association with sulphides - making geophysics feasible. On the downside the lab. chosen sounds like a bit of a dog's breakfast but shipping of samples for analysis outside a country (and during Covid) comes with risks - so I wouldn't knock that. Brad sounds like a sound-minded bloke to me.
