I should correct myself a bit about the Noble testing as it's not as clear as that but this is what was in the ASX announcement:
'Data collected from drilling the Mbelele-1 well indicates a 10-15 metre column of free gas within the upper part of the Mbelele structure, consisting of a mixture of helium and nitrogen. While as previously advised a sample of the gas could not be collected, this interval encountered the highest helium readings in mud-gas for the entire drilling program and the Company is now working with NSAI with a view to satisfying the requirements under the guidelines of the SPE-PRMS for declaration of a conventional helium discovery. The Company considers the free gas as potentially material to its early monetisation plans and intends to revisit this gas intersection as soon as possible with a small, low-cost rig for sampling and flow testing.
Gas-phase helium was further recovered at surface from fluid samples taken from deeper reservoirs beneath the free gas column within the Mbelele structure. As the fluid samples were brought to surface, they depressurised naturally and gas came out of solution (‘exsolved’) into free gas, which was then calculated to contain Nitrogen and 2-3% Helium (after correction for air contamination). This represents the minimum amount of helium contained within the fluid sample. Evidence indicates all of the reported reservoir intersections at Mbelele-1 and Mbelele-2 contain these helium-enriched fluids. Not only did each reservoir have helium shows in mudgas, in numerous cases exsolution bubbles with elevated helium were identified in the mud system while drilling, demonstrating high levels of gas saturation.'
