Bamps - if this is the one you are talking about from February 2018 then it says the main ore-body could be up to 650,000,000 tonnes. It says the smaller body is immediately adjacent to the primary body - maybe a good shout for the drilling in the SW ??

"Forward modelling of detailed aeromagnetic data (50m line spacing and 40m mean terrain clearance) and detailed ground gravity data (100m x 100m and 100m x 200m station spacing) over the Havieron target was completed in February 2018 by independent geophysical consultants. Results of forward modelling have defined a primary body approximately 600m x 600m across with a depth extent from 400m to 900m below surface resulting in a potential volume of more than 240,000,000 cubic metres and an estimated mass of more than 650,000,000 tonnes. A second smaller body with a volume of more than 16,000,000 cubic metres lies immediately adjacent to the primary body. Results of forward modelling are indicative only as geophysical data is ambiguous, however modelled bodies were constrained to known physical rock properties and therefore potentially represent the core of the mineralised system at Havieron. Forward modelling suggests that of the six historic drill holes completed at Havieron only two intersected the target. Those two holes intersected only the very top of the mineralised system but returned over 100m of mineralisation (HAC9101) and over 50m of mineralisation (HAC9201) peaking at 15.4g/t gold and 2.5% copper within broad, lower grade intercepts"
So their forward modelling and surveys obviously have held up pretty well and are being proven by the NCM drilling.
In the same RNS they reported that they had carried out MMI & Ground Gravity surveys at Havieron and Ground Gravity at Scallywag. Interestingly they reported that the Ground Gravity was a success at Scallywag but it was just a one-liner.
"Gravity results from Scallywag show gravity highs co-incident with the magnetic targets over approximately 2km of strike."
If you listened to the video with Sam Garrett who had Havieron before GGP, that was one of his reasons for initially taking the Havieron license - the Gravity & Magnetic co-incident response. Listen from about 5 mins in.
