Shuka caught my eye this morning with their RNS.
I don't know the full background here, so I'm sure someone will correct me if I have got the wrong end of the stick.
However Shuka reaching a deal with Upendo, bearing in mind the recent events in the Rukwa Valley could be an interesting development.
It is all to do with geography.
This is a map taken from the Tanzanian Mining Portal showing Edenville's licences (I know the company is now known as Shuka, but the licences are still in the Edenville name, I'll probably use both from time to time, but they are the same, of course).

Now the licence I'm really interested in this the one highlighted showing Edenville as 70%, Upendo as 30%.
I'm not quite sure how this fits in with Upendo having a legacy 10% interest as described in the RNS, however I'll gloss over that and whatever the disputes or interests are, they've obviously been settled on terms.
And just for context these are all the helium licences in the North Rukwa Rift Valley, Edenvilles are towards the upper left, but they're for coal and other commodities so weren't included when I did this map.

Now the interesting thing is that the dispute has been settled now following two companies apparently finding helium in significant quantities in the rift valley. Geology is also important as the helium is theorised to be generated deep underground within the rift, and its release is aided by volcanic heating. But the helium also has to be trapped by sedimentary rocks within the rift, most of it actually escapes.
Noble is targeting BMFC's on the edges of the rift, along the two main faults that form the rift itself. He1 is targeting IBFC's within the rift itself. Two quite different plays, but both have licences containing both types of closure.
Now Edenvilles three main licences fall outside the rift valley, so in theory any helium there should simply escape through the faulting system and not be trapped.
But the licence Edenville holds with Upendo (70/30) doesn't fall outside the rift, it falls within the BMFC, and here is a view of that looking from the north to south, with the Edenville/Upendo licence shown yellow, edged blue in the lower right corner.

The interesting thing is that this licence is bounded by the main Ufipa fault, but within the sedimentary rock area where Noble says they have found gaseous helium, Mbelele-1 is 31km SE of this licence area.
This is another view, again looking south, showing the Edenville/Upendo licence, Nobles well/licences, He1 wells/licences, and the Rungwe volcanic Province towards the top.

Interesting development. Will keep an eye out.
