4D Hyperspectral
Imaging

4D Hyperspectral Imaging (4DHSI) is a proprietary nano-electromagnetic mineral detection and modelling platform that uses Hyperspectral Imagery (HSI) captured by Earth-orbiting satellites to identify, position, and quantify mineral deposits from space — without ground disturbance, drilling, or physical sampling.

The HSI technique collects information of a target site across the full electromagnetic spectrum, from below ultraviolet to above long-infrared. This spectral data is processed through proprietary nano-electromagnetic methods to model mineral deposits in two dimensions (surface area mapping) and four dimensions (three-dimensional volumetric modelling with depth profiling over time).

The technology is capable of identifying and quantifying gold, rare earth minerals, diamonds, silver, copper, and other valuable minerals in a single satellite pass. It can characterise deposit boundaries, estimate quantities by depth, identify heterogeneous mineral co-location, and provide the data required for efficient, targeted extraction — dramatically reducing the time, cost, and environmental impact of conventional exploration programmes.

The MANF-01 demonstration was conducted on a site block of 8.52 km² in the Kankan region of north-western Guinea, centred on the town of Manfarani. A Hyperspectral Imagery satellite scan was performed across 28.40 km² encompassing the subject area. Investigators were given no information regarding known deposits prior to conducting the analysis — the results were entirely derived from the satellite data.

The site has a radius of 1.83 km and a subterranean investigation depth of 500 metres, representing a three-dimensional investigation volume of approximately 4.26 km³. The Republic of Guinea confirmed the site was known to contain gold and rare earth mineral deposits. The 4DHSI platform identified both, without prior information, and additionally identified diamonds, silver, and copper at depth.

For governments and mining companies working in regions where conventional exploration is expensive, slow, and environmentally disruptive, 4DHSI represents a fundamental shift in the economics of mineral discovery.

A conventional ground-based or airborne exploration programme covering 8.52 km² to 500 metres depth, across five mineral species simultaneously, would take years and cost tens of millions of dollars. The 4DHSI platform delivers equivalent or superior deposit characterisation data from existing satellite imagery — in weeks, at a fraction of the cost, with zero ground disturbance.

For countries like Guinea — resource-rich but capital-constrained — the ability to produce bankable deposit data for known but uncharacterised mineral concessions, without requiring large upfront exploration capital, opens new pathways to project financing, partner attraction, and in-country value realisation.
