Global model
Ranked targets come with national models in Australia and the United States. Everywhere else, the global model returns the prospectivity map, the geology behind it and a confidence read. Next, the models are retrained on the full record and new sources, such as hyperspectral imagery, before we use them to rank and select ground.
How we rank europium ground
From a country to a decision.
- 01 · Atlas
Know the ground
The geology, structure, recorded deposits, tenure and geochemistry over the ground, on one map with the source of every layer.
See Atlas - 02 · Open Ground
Find ground you can peg
Which ground is open, held or excluded, read from each licensing authority's own register.
See Open Ground - 03 · Prospectivity
Rank it for europium
The ground scored for europium, with the evidence behind it and ranked targets in Australia and the United States. Anywhere else, the global model maps europium.
See Prospectivity - 04 · Spectral
Map the alteration
The alteration minerals and the structures that control them, from satellite: regional to district scale, and camp scale from WorldView-3.
See Spectral - 05 · Due Diligence
Check before committing
Tenure, land access, environment and the real cost to hold and test a europium position.

The deposit system
The europium system.
Europium is the most reactive of the rare earths and, gram for gram, one of the most valuable: the element behind the red and blue phosphors that made colour television possible and that still light LED displays, lamps and security features today. It has no ores of its own: europium substitutes in trace amounts into the same carrier minerals as the other rare earths (bastnäsite, monazite, apatite, xenotime) within carbonatite intrusions and alkaline igneous complexes, and is recovered as a companion product of rare-earth mining.

More on europium
MineDSS models europium through those host systems.
The deposit model
Europium's geochemistry is distinctive (under reducing magmatic conditions it partitions into feldspar as Eu²⁺, which is why many evolved rocks carry a europium anomaly), but as an exploration target it follows the rare-earth systems that host it. Carbonatites concentrate europium within their light-rare-earth minerals, bastnäsite and monazite; alkaline igneous complexes carry it in apatite, xenotime and eudialyte alongside the full incompatible-element suite. Both system types are marked by alkaline and carbonatitic geology, thorium-bearing radiometric anomalies, magnetic ring signatures and fenite alteration.
Why it matters
Europium's economics are the sharpest expression of rare-earth criticality: tiny volumes, near-total supply concentration, and no substitute that reproduces its red and blue emission in phosphors. It appears on the critical-minerals lists of the United States and other jurisdictions. Any new light-rare-earth source with a healthy europium budget improves a supply chain that currently depends on a handful of operations worldwide.
Where it's used
Europium's defining application is phosphors: trivalent europium provides the red and divalent europium the blue in LED lighting, displays, lamps and plasma screens, and europium phosphors are the machine-readable security feature in many banknotes. It also serves in specialty lasers and scintillators, in nuclear control applications as a neutron absorber, and in research optics. Almost all demand is met as a by-product stream of bastnäsite and monazite processing.
Questions
Europium: common questions.
Which europium deposit types does MineDSS model? +
Europium is a companion product of rare-earth mining rather than a standalone target, so MineDSS models its host systems: carbonatite intrusions, whose bastnäsite and monazite carry europium in the light-rare-earth budget, and alkaline igneous complexes, which hold it in apatite, xenotime and eudialyte. Both leave the alkaline-geology, radiometric and incompatible-element footprint the model is built to read.
How is the model tested, and where can I run europium? +
Every MineDSS model is tested before it is served: we withhold whole blocks of ground, rebuild the model without them, and check that it still ranks the anomalous samples there above background, with test ground kept spatially separate. A model that does not pass our release gates is not used, for any mineral, in any country. National models for europium run in Australia and the United States, with ranked targets. Anywhere else in the world, the global model returns the prospectivity map, the geology behind it and a confidence read. Skill is model-level, never a specific site's measured accuracy, and never a discovery or JORC / NI 43-101 resource claim.
Which pathfinder elements track europium? +
The co-located incompatible-element family: zirconium, niobium, thorium, uranium, hafnium, tantalum and beryllium, with zirconium, niobium and thorium leading. Europium enrichment occurs only within functioning rare-earth systems, and these high-field-strength elements are those systems' most reliable geochemical trace. These elements are part of the geochemical record our models learn from. In a run on any piece of ground, the map itself is read from geology and rock age, gravity and magnetics, radiometrics, terrain, satellite radar and spectral alteration, so it covers ground that has never been sampled.
Does a high MineDSS score mean a deposit or a resource estimate? +
No. A high score means its evidence closely matches ground where samples assay anomalously high for the target mineral, and it merits closer exploration attention. It is not a discovery, not a JORC or NI 43-101 resource or reserve estimate, and not drilling or investment advice. MineDSS ranks prospectivity to help prioritise where to look; confirming whether europium is present, and in what grade and quantity, still requires field programmes, drilling and independent assessment by qualified professionals.
