The T4 results are for a zone of Cu found in the boundary between the footwall and hanging wall and are typical of the Kalahari copper belt. You can see in this representative diagram that the these zones of mineralisation are typically thin and go very deep.

In the case of T3 the zone of Cu is thick and almost horizontal (like a lens) and is associated with quartz veining.
According to Mr Janse van Rensburg this is different to what he has seen in the past 8 years and the amount of quartz veining associated with chalcopyrite and bornite points to a hydrothermal type of mineralisation.
What was being drilled at T3 was a
25 km gravity anomaly of a buried dome of something shown by the magnetic data. But MOD did not yet hit the footwall/hanging wall mineral deposit when they drilled T3, they have found something else that has been formed in a different way.
The potential size of what MOD has found at T3 is what has moved the share price and if it is confirmed then this will be life changing for those involved.
Hope that helps explain the reaction to the T3 results as compared to T4.
