Thorium prospectivityacross Australia, the USA, Canada & worldwide.

MineDSS models three deposit systems: alkaline igneous, carbonatite and placer. Carbonatites host thorium in monazite, thorianite and pyrochlore alongside rare earths and niobium, often enriched further in weathered carapaces. Alkaline igneous systems (peralkaline syenites and granites) carry thorium in complex silicates such as eudialyte and allanite together with zirconium, beryllium and lithium. Placer systems concentrate chemically resistant, dense monazite into heavy-mineral sands alongside zircon, ilmenite and rutile. The model does not attempt to represent unrelated styles; it ranks ground by how closely its evidence matches ground where samples assay anomalously high for the target mineral.

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 thorium run in Australia, the United States and Canada, 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.

The classic pathfinders are led by uranium, yttrium and niobium, and completed by zirconium, beryllium and lithium. Uranium is thorium's radioactive twin and co-enriches in the same systems; yttrium proxies the heavy rare earths that travel with thorium in monazite; niobium marks the pyrochlore and carbonatite association; and zirconium, beryllium and lithium track the highly differentiated alkaline and pegmatitic rocks that concentrate thorium. 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.

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 thorium is present, and in what quantity and grade, still requires field programmes, sampling and independent assessment by qualified professionals.
