Infinity Mining and Fleet Space Technologies Take the Search for Essential Elements to New Depths at Tambourah South

Flavia Tata Nardini, CEO & Co-Founder, Fleet Space Technologies said: “We’re delighted to be working on a major domestic mineral exploration project with a fellow Australian-owned company. ExoSphere gives Infinity Mining a unique opportunity to use our advanced ANT technology to map possible lithium-bearing pegmatites, potential host rocks and controlling structures at depth. The system is ideally suited to the rugged terrain of Pilbara, where our Geodes’ light weight and portability really come into their own. Combined with Infinity’s existing data, the ANT data will give the team a better understanding of Tambourah South’s overall geology, aiding drill targeting and speeding up the development of commercially-viable deposits of these vital minerals.” 

Infinity Mining will deploy Fleet Space's ExoSphere, to enhance mineral exploration activities and decrease time spent exploring for deposits of lithium, rubidium, and rare earth elements at Tambourah South.

The use of ExoSphere will significantly reduce the amount of scout drilling required, saving time and resources as LCT pegmatites follow structures within greenstone units making them elusive and difficult to find using established drilling protocols. 

These minerals play a crucial role in several industries, including the transition to renewable energy. ExoSphere's advanced capabilities will allow Infinity Mining to explore deeper and more thoroughly, improving the likelihood of discovering previously untapped mineral deposits. The successful deployment and delivery of ExoSphere at Tambourah South could pave the way for more efficient and effective mineral exploration across the Pilbara’s rouged terrain.

ExoSphere consists of real-time, satellite-enabled seismic nodes specifically designed for mineral exploration in remote settings called Geodes. The Ambient Seismic Noise (ANT) data is transmitted to a constellation of low earth orbit (LEO) satellites, then relayed to computers that use intelligent data processing to generate detailed 3D subsurface maps. The combination of Geodes and satellite connectivity allows small teams to map vast amounts of land accurately and with little to no environmental disturbance. Plus, unlike traditional methods, which can take months to years to complete, data collection and processing can be completed in a matter of days.

ANT will enable Infinity Mining to map where lithium-bearing pegmatites identified at the surface are going at depth, if they are thickening up and whether they are merging with other pegmatites. It will also help identify concealed pegmatites that don’t have surface expressions, and provide 3D mapping of favourable host rock units and structural controls on pegmatite development.

At Tambourah South, the data will be collected over a one-month survey period. The aim is to map the pegmatites dykes at depth and identify areas where the pegmatites have formed large structurally controlled Li-REE deposits. The lightweight, portable Geodes are easy to deploy in the area’s rugged topography, where conventional techniques make mapping and defining the extent of pegmatite swarm difficult.

ExoSphere’s passive seismic Geodes record the ambient seismic noise within the Earth’s upper crust, generated both by natural sources such as wind and wave action, and human activity such as nearby mining operations and even vehicle movements. This real-time data is transmitted by satellite to computers that build it into a complete 3D picture of the entire subsurface structure down to several hundred meters in depth.

Joe Groot, CEO of Infinity Mining, commented: “The ANT technique is easy to deploy, data is recovered in real time and requires no ongoing field work once in place. If the technique proves useful at Tambourah South, Infinity could also deploy it in other tenements where cover and topography are hindering surface exploration and drill targeting. I would like to personally thank Dr Darryn Hedger (Infinity Mining) and Mr Steve Ledger (Fleet Space) for their collaboration in adapting this new imaging technology to suit lithium exploration in the Pilbara region of Western Australia.”
