Just some notes I made, might be of interest, might not be accurate,,
Lake Rukwa is an alkaline lake and contains salt pans by its southwestern ends. Like many salt lakes, Rukwa has no outlets and many inflowing rivers that can bring salts. Offering a high likelihood of salt seal occurrence.
In 1929 it was only about 48 km long, but in 1939 it was about 128 km long and 40 km wide.
Last measured it was roughly 180 km long, averaging 32 km wide, covering 5,760 Km^2.
The Rukwa field is 3,448Km^2, located in, and around the southern half of the lake.
The 3 prospects, Kasuku, Mbuni and Itambula appear to be on the southwestern end of the lake, on an old dried up bed.
Itumbula springs show 8%-10% Helium.
Using the Geophysical heat map presentation, with Mbuni as the reference, adjacent Kasuku is ESE(~5km away), while Itumbula is ENE(~10.5km) with Chiriku and Mizizi in-between.
Mbuni is expected to have a higher unrisked(p50) yield, 7bcf compared to the others 5bcf each, but this is risk based using 4.2.% helium by volume not 8%- 10%.
So drilling results could give significantly higher bcf values especially for Itumbula(springs)
Starting with an initial exploration well, there could be up to 7 production wells in a 10km^2 field.
