Helium One Global commences ERT survey at the Rukwa project area

Helium One

Helium One Global Ltd (LON:HE1), the primary helium explorer, has announced the commencement of an Electrical Resistivity Tomography survey at its Rukwa (100%) project area.

Highlights

·    Initial testing completed over Tai prospect with data collected to date justifying continued operation

·    ERT to image specific priority areas identified from Phase I and Phase II 2D seismic as well as investigating surface helium anomalies identified in recently completed multispectral satellite spectroscopy (“MSS”) study

·    Results will contribute towards out understanding of the helium system and future exploration planning

Background

The ERT survey is designed to identify resistivity anomalies within the ultra-shallow zone (<200m), allowing a better understanding of near surface geology which is poorly resolved by seismic. The survey is best run during the rainy season where saturated ground conditions allow better coupling of source and electrodes, providing improved resolution to depth.

Data collected from the survey can be used to direct further study into areas that could be prospective for potential shallow gas accumulations.  Near surface geophysical investigation also assists in correlating surface anomalies identified in recently acquired MSS studies with deeper lying structures identified in 2D seismic.  Interpreted data can allow the Company to better understand helium charge and migration across the prospective area.

Work has commenced with test lines satisfactorily completed over the Tai prospect.  Processed data shows sufficient response to justify continuation of the ERT survey over other priority targets identified in Phase I and Phase II 2D seismic campaign, as well as near surface helium anomalies recently identified by multispectral satellite spectroscopy.  

David Minchin, Helium One Global Chief Executive Officer, commented: 

“We are pleased to have commenced our ERT survey at the Rukwa project area.  With the arrival of the rainy season providing saturated ground conditions ideal for running the ERT survey, results to date have shown interesting resistivity anomalies that justify additional data acquisition, interpretation and evaluation.

“Having completed our testing phase over the Tai prospect, the survey team will now move on to investigate other priority targets identified in Phase I and Phase II 2D seismic, as well as areas with near surface helium anomalies identified in our recent MSS study.

“We look forward to receiving the results of this survey which will contribute significantly to our understanding of potential shallow helium plays within the top 200m of the Rukwa basin.”
