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 praseodymium 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 praseodymium
The ground scored for praseodymium, with the evidence behind it and ranked targets in Australia and the United States. Anywhere else, the global model maps praseodymium.
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 praseodymium position.

The deposit system
The praseodymium system.
Praseodymium is a light rare-earth element that works alongside its neighbour neodymium in the world's most important permanent magnets. The two are so closely paired in nature and in industry that they are often traded together as didymium.

More on praseodymium
It occurs in the classic light-rare-earth carrier minerals, bastnäsite and monazite, within carbonatite intrusions and alkaline igneous complexes, and MineDSS models it through those systems.
The deposit model
Carbonatites are the principal praseodymium source: mantle-derived carbonate magmas whose crystallisation and late carbothermal fluids concentrate bastnäsite, monazite and apatite, with praseodymium consistently accompanying neodymium, lanthanum and cerium in the light-rare-earth budget. Alkaline igneous complexes (peralkaline granites, syenites and their pegmatites) host the same elements in more evolved mineral assemblages. Both are marked by rare alkaline and carbonatitic geology, thorium-bearing radiometric anomalies, ring-like magnetic signatures and fenite alteration halos, and both carry the coherent incompatible-element halo that distinguishes a genuine rare-earth system from ordinary crust.
Why it matters
Praseodymium sits on national critical-minerals lists as one half of the neodymium-praseodymium (NdPr) couple that drives the permanent-magnet supply chain: the magnets inside electric-vehicle traction motors, wind-turbine generators, robotics and consumer electronics. Magnet demand is the fastest-growing segment of rare-earth consumption, mine supply and separation capacity remain geographically concentrated, and every credible new light-rare-earth source strengthens a strained supply chain.
Where it's used
Most praseodymium is consumed in neodymium-iron-boron magnets, where it substitutes for part of the neodymium, and in didymium alloys. Beyond magnets it strengthens the magnesium alloys used in aircraft engines, colours glass and ceramics a characteristic yellow-green, filters yellow light in didymium welding and glass-blowing goggles, and serves in fibre amplifiers and speciality optics. Its demand outlook tracks the electrification of transport and power.
Questions
Praseodymium: common questions.
Which praseodymium deposit types does MineDSS model? +
The light-rare-earth systems: carbonatite intrusions (whose bastnäsite, monazite and apatite carry praseodymium alongside neodymium, lanthanum and cerium) and alkaline igneous complexes, where evolved granites, syenites and pegmatites host the same element family. Both leave the distinctive alkaline geology, thorium radiometric signature and incompatible-element halo the model is built to read.
How is the model tested, and where can I run praseodymium? +
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 praseodymium 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 praseodymium? +
The co-located incompatible-element family: zirconium, niobium, thorium, uranium, hafnium, tantalum and beryllium, led by zirconium, niobium and thorium. Thorium is monazite's constant companion, so it doubles as both a geochemical and a radiometric trace of light-rare-earth systems. 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 praseodymium is present, and in what grade and quantity, still requires field programmes, drilling and independent assessment by qualified professionals.
