Goliath target is very intriguing for me,
I've been looking at the blown up plan and cross section, on the web site you can only find it now in the Jorc section Nov 19 announcement.
The Residual gravity survey and the magnetic survey are shown above this. On these they've plotted the 3 historic drill holes, on the gravity one it's missed the centre of the high gravity area but on the magnetic they've just clipped it.
It looks like they were targeting the magnetic zone.
When you then look at the blown up map you can see the white area of the high gravity zone and also you can see the magnetic contours. To the NW of the central zone the contours form a tight ring and looking at section A you can see a blob shape which is the tight ring.
This is all between 200-1200m below surface.
The volume is about 785,000 cubic metres or 2.1bn tons
Havieron 176,000 cubic metres or 484m tons
This is the magnetic anomaly above 1,000m depth but it is also the coincidence with the high gravity zone.
We also have MMI results for this target.
So from what Goldworm suggested:-
Goliath has:-
Coincidence - tick
High magnetic zone - tick
High gravity zone - tick
MMI results - tick
2,100,000,000 tons
Cut off grade 0.2g/t Au 13.8m oz
Cut off grade 0.2% Cu 4.3m tons.
When you go back to the cross section between 1200-2400m below surface the coincidence continues and is far larger.
Looking to the plan again, the contours below the ring are more spread out indicating a flatter zone . This flatter zone spreads out southwards, you can see this on the cross section just below the 1000m and will get wider the further south you go.
I have calculated the tonnage but the figures are embarrassingly large for the coincidence from 1200-2200 below surface,
I don't want to be seen Bamping :)))
