ExoSphere is a first-of-its-kind passive, non-destructive mineral exploration solution combining three radical technologies: ambient seismic noise tomography (Geode sensors), low-power satellite connectivity (Alpha constellation) + intelligent cloud-processing (Nebula visualisation-software), to discover critical resources 100x faster than traditional methods, while drastically reducing the requirement for environmentally damaging elements of existing surveillance practices.

  • At this critical point for our planet, the world is rapidly transitioning to green energy and cleaner industrial operations. The IMF predicts that in just two decades more than $13trillion (USD) worth of the four major energy transition minerals must be mined to reach net zero ambitions. This requires more sustainable, faster and economically viable exploration practices. Exploration is a costly, time intensive, manual process with varying levels of accuracy and scope, with efficiency being a critical metric for investors. New technologies are converging to revolutionise exploration with unprecedented opportunity for those who embrace innovation.

  • Our end-to-end solution ExoSphere is combining revolutionary non-invasive, low environmental impact sensors, unlimited global satellite data transmission and intelligent cloud processing to create a lightning fast, highly scalable, 3D exploration solution to rapidly pinpoint high value minerals beneath the earth to identify sources of these critical resources. This removes the need for invasive drilling practices, significantly reduces cost and can speed up discoveries more than 100x. We are proud to enable this critical step in mining to provide better access to resources we need to make a better future for humanity, and unlocking exploration at a scale never before possible.

  • Founded to open new frontiers on Earth and beyond, Fleet is building a prosperous and sustainable future for humanity. Now that's threatened by climate crisis, we’ve focused on how we use our revolutionary technology to help. Designed to explore space, Fleet can help on Earth finding resources needed to reach net-zero by 2050, making mineral exploration hyper efficient, lightning fast, with less environmental impact. Reaching net-zero is vital but unachievable without critical minerals. If we can’t explore rapidly, responsibly and widely enough discovering abundant deposits, the frantic satisfaction of demand could be catastrophic for communities, while delaying the energy transition.

  • Fleet’s solution is a first-of-its-kind system that combines wireless Geodes, edge-processing and intelligent cloud-processing, and a constellation of low-earth-orbit nanosatellites to discover critical resources up to 100 times faster than traditional methods. ExoSphere also drastically reduces the requirement for environmentally damaging elements of existing surveillance practices like explosives, noise machines and drilling, presenting a passive, non-destructive technique to assess site viability for mining minerals. Our in-house designed ruggedised, battery-operated Geodes contain sophisticated processing units, direct to satellite transmitters, and seismic sensors. The Geodes use the principles of seismology to map the properties of Earth’s subsurface from reflected seismic waves by recording ambient noise - a process known as Ambient Noise Tomography. Once sufficient ANT data is gathered, raw information is partially process on site, reducing data requirement for transmission (edge processing) that significantly increases connectivity speed between IoT devices, allowing more data to be sent using less power. This data is securely pushed to Fleet’s network of low-power satellites. Quickly and easily deployed by small local teams, customers receive 3D mapping visualisation of the subsurface down to 2km depth in 4 days, instead of traditional 6 months that included waiting for devices to be collected, shipped, and unpacked to collect data.
