Noble Helium Limited announced that the Soil Gas Survey ("SGS") program being carried out by the University of Dar es Salaam over the Company's 100% owned North Nyasa Project area in Tanzania has now been successfully completed, on time and budget. Analysis of the results are ongoing, but encouragingly, some samples within the Company's North Nyasa Prospecting Licences (PLs) demonstrate anomalous helium concentrations at up to 7.8 parts per million (ppm), or over 40% above background. This additional helium can only be explained as the result of micro-seepage from underground.

Infill SGS programs were carried out over the areas of anomalous helium micro-seepage, providing greater detail on their extent. The Company will now carry out a detailed analysis of the North Nyasa SGS data. In combination with the legacy airborne gravity gradiometry and 2D seismic exploration dataset, the company expects to develop a Prospective Resource Estimate in 2023, following the same process that achieved an independently certified unrisked summed mean Helium Prospective Resource of 176BCF at the Company's North Rukwa Helium Project.

Soil Gas Surveying involves sampling the soil on a regular grid, one metre below ground, for helium and other useful indicator gases such as argon, CO2, nitrogen and methane. The method is an indirect indicator of helium and other gases present and potentially trapped much deeper underground, particularly for results that are significantly higher than background readings, as seen at North Nyasa. The North Nyasa Project is located 230km southeast of Lake Rukwa in the Western Branch of the East African Rift System and is in the same rift segment as the Rukwa Rift.
