Cross Sections23 Aug 2020 09:48
I've been looking at the cross sections of Havieron and Scallywag.
At Havieron there were 2 historic surveys a ground magnetic and a ground gravity, also there were 4 historic drills , 3 were just outside the magnetic survey and 1 just inside. Only 1 hole came anywhere near the centre of the coincidence of both surveys.
GGP's first 4 holes are all in the coincidence of the surveys.
Cross sections 1 and 2 traverse SW to NE
through the coincidence. There are 6 drills to the SW on these cross sections and they have been stepped out in order to hit the High grade zone at the right angle through 400m of cover, it's nothing to do with a new zone in that direction and they're outside the coincidence.
The Breccias look as though they keep on going down below the HGZ and seem to be widening .
The Kraken anamoly has an IP survey cross section and a 3D magnetic model overlaid on to it. The coincidence looks very strong and I would expect the drills to be centred on it.
The coincidence doesn't look deep but they're saying on the web site it has a deep magnetic structure similar to Havieron but the IP depth is limited.
Blackbeard cross section shows the IP survey with 3D magnetic model overlaid .
It's a long structure and shows 2 or 3 coincidences but more importantly the 3D model looks very deep way below the IP survey. I believe a 3D magnetic survey can reach depths of 1400m.
London is a different geology and no section but sounds deeper from its description.
The MMI sampling surveys have indicated mainly copper, I think the high grades of Havieron will not be found at Scallywag but the bulk tonnages could be enormous.
