Fleet Space Technologies has terminated its contract with Resonance Frequency Exploration Group (RFEG), which the company signed to deploy ExoSphere satellite-based mineral exploration system in Africa.
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 then relayed to computers that use intelligent data processing to generate detailed 3D subsurface maps. Unlike traditional prospecting methods that can take months or years to complete, the whole process takes only days or weeks.
ExoSphere brings a new dimension to the ongoing Mineral Resource Estimate projects RFEG is conducting, in particular 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 and non-invasive, operating without the need for explosives or vibrating trucks to collect subsurface seismic data. Fleet claims, this substantially reduces costs, logistical issues and environmental disturbance.
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, Central and South America take a more tech-forward, eco-conscious approach to better ascertain site viability and increase operating efficiencies. In particular, it is focusing on using satellite-based image processing technologies analysed by proprietary algorithms to determine a prospective site’s viability before embarking on traditional geophysical work.
