The ongoing Tanzania-based helium project Helium One has identified multiple additional surface helium anomalies across its three project areas following the completion of a remote sensing study.

The study used multispectral satellite spectroscopy (MSS) to analyse emissivity data which generated a heat map for helium signatures across the company’s 4,500km2 licence area, revealing widespread helium charge and migration across Rukwa, Eyasi and Balangida basins. 

Commenting on the study, David Minchin, CEO, said, “We are pleased with the results of the recently completed MSS study which identified abundant helium anomalies over all three basins.” 

A ‘robust’ helium anomaly was identified across the Tai structure, which has previously indicated subsurface helium through the identification of good quality reservoir and seal units. 

Additional surface anomalies within the Phase II 2D seismic area will help aid in the interpretation of the seismic data as well as target prioritisation. 

The anomalies identified within the three basins could provide information on prospectivity and will be examined using soil-in-gas analysis, ERT and 2D seismic geophysical investigations. 

Following the discovery of the anomalies, Minchin laid out the project’s next steps, saying, “Next steps must be to ground truth the data and then combine information on newly identified surface helium anomalies, with data from 2D seismic, airborne gravity gradiometry and knowledge of the helium system gained from phase I drilling.” 

The Helium One team can then use this data to prioritise subsurface traps that will be testing during its 2022 drilling campaign.
