Fleet Space has announced the first deployment of its ExoSphere satellite-based mineral exploration system in Africa in a new partnership with Resonance Frequency Exploration Group (RFEG), based in the USA, with operations in Accra, Ghana. 

Under a licensing and technology cooperation agreement finalised in December 2022, Fleet Space will supply its Geode portable sensors, which use Ambient Noise Tomography (ANT) to collect subsurface data. This data is then beamed to the ExoSphere constellation of low earth orbit (LEO) satellites and relayed to computers that use intelligent data processing to generate detailed 3D subsurface maps. Unlike traditional prospecting methods, which can take months or years to complete, the process only takes days or weeks. 

Exosphere brings a powerful new dimension to the ongoing Mineral Resource Estimate projects RFEG is conducting, particularly in the Oti Region of Ghana. Under the auspices of the Ghana Geological Survey Authority (GGSA), with implementation by RFEG’s team, ExoSphere will complement RFEG’s own XPLR remote-sensing mapping-analysis technology. This is achieved by cross-referencing the data from both sources, thereby significantly increasing the likelihood of finding new mineral deposits more quickly and with much greater accuracy. 

ExoSphere’s Geodes are light enough to be carried by one team member, making them ideal for use in challenging and inaccessible terrain. They are also non-invasive, eliminating the need for explosives or vibrating trucks to collect subsurface seismic data. This substantially reduces costs, logistical issues and environmental disturbance; the accuracy of the combined data collection and analysis by Exosphere and RFEG’s systems also means, for mining operators, that drilling can be streamlined to areas where considerable deposits are known to exist. 

RFEG selected Fleet Space as its technical partner after a worldwide search. The company is seeking to help current and prospective clients in the USA, Africa, and Central and South America take a more tech-forward, eco-conscious approach to ascertain site viability better and increase operating efficiencies. In particular, it focuses on using satellite-based image processing technologies analysed by proprietary algorithms to determine a prospective site’s viability before embarking on traditional geophysical work. RFEG founder Schad Brannon said: “The addition of ExoSphere 3D rendering of subsurface topography by Fleet Space propels the XPLR technology product suite and technology stack to the next level by creating the most comprehensive satellite-based remote sensing survey product available within the mineral exploration marketplace to date”.
