Part 2
Well very deep, possibly down to 40km+ right down to the Moho, which is the boundary between the Crust and Upper Mantle, shown here https://www.flickr.com/photos/194934344@N06/53714482060/in/dateposted-public/ And this shows that this profile 3-3' is taken from exactly where these new drill locations are being created https://www.flickr.com/photos/194934344@N06/53712688212/in/dateposted-public/ This is another theorised image showing the Ifipa fault going down to around 30km https://www.flickr.com/photos/194934344@N06/53713583526/in/dateposted-public/ But this is the thing - it is all fairly theoretical, as very little deep exploration work has been done around Rukwa, it is effectively virgin territory. He1 IMHO don't know where the fault at Itumbula goes, how deep it is, whether it joins with the Ufipa fault many km down, or exactly where the helium is generated which then flows into their fault at Itumbula. But it would appear (to me) that whoever is preparing to drill at Ilemba is targeting the deepest fault that they can find, which goes all the way down to the base of the Earths crust. Work started at Ilemba around last September, long before the Itumbula result was known. We'll never know why they were diverted to Tai, which could be a conventional reservoir, but it seems to me that both Itumbula and Ilemba are targeting quite different plays, not reservoirs but helium flowing upwards, possibly from 30-40km deep, and it is for this reason that He1 have not revealed any detailed results. They simply don't know what they have got, as they've never seen the like previously. The EWT may give an idea, and help to quantify. Whether it is Noble at Ilemba, who knows, can't think it could be anyone else, but why so secretive? But I think any results from Ilemba, could have a material effect on how Itumbula is quantified. And we never did find out what was in the Noble/He1 cooperation agreement, did we?
