Just in response.
The figure quoted by Lorna Blaisse, she herself stated was conservative.
Secondly this is a free-flowing rate from the Basement.
Not one bit of stimulation has been involved any point.
The one thing people are overlooking at Itumbula and that I'm equally as interested in is this
"The well has been successfully drilled to 961m MD and has reached its TD in granitic Basement. The well encountered elevated helium shows, over twenty times above background, whilst drilling through the Lake Beds Formation, Red Sandstone Group, Karoo and Basement targets. Elevated readings and an increased frequency of helium shows were encountered whilst drilling through the faulted zone."
We only know about the 4.7% Helium from the Basement. There are 3 other layers here with reported elevated Helium shows.
Noble Helium btw only drilled the shallowest Lake Beds formation and got two large reservoirs of Helium, the combined depth of which is the height of the Rock of Gibralter.
"Net Reservoir thickness increased across both wells
NHE confirmed that net reservoir thickness increased by 3x for Mbelele-1 and 2x for Mbelele-2.
Net reservoir thickness for the two wells now sit at 148m (Mbelele-1) and 271m (Mbelele-2).
NHE also confirmed high porosity and permeability across the two reservoirs."
It might also let you see how these initially conservative figures can improve. Incidentally the additional free flowing 20M Gas Cap that Noble Helium have - just multiplied itself x 6.
This isn't being called a "Unique and Prolific Helium Producing System Unlike Any Other In the World" without very good reason.
