Gallium prospectivityacross Australia, the USA, Canada & worldwide.

MineDSS models the two host families that actually carry gallium: aluminous host systems and zinc-sulphide host systems. Because gallium forms no ore of its own, the aluminous family covers bauxite (where lateritic and karst weathering concentrates gallium-bearing gibbsite, boehmite and diaspore) together with the highly-evolved, aluminium-rich granites and pegmatites that enrich it magmatically. The zinc-sulphide family covers sphalerite-bearing deposits, in which gallium substitutes for zinc and is recovered from zinc concentrates. 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 gallium 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 aluminium, rubidium, tin, niobium, beryllium and lithium, with aluminium, rubidium and tin leading. Aluminium is gallium's geochemical twin, marking the aluminous bauxite and igneous hosts into which gallium substitutes, while rubidium, tin, niobium, beryllium and lithium trace the strongly fractionated granites and pegmatites where it concentrates. The gallium-enriched samples the model learns from assay at or above 50 ppm. 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 estimate, and not drilling or investment advice. It also does not by itself imply an economic operation: gallium is recovered only as a by-product of aluminium and zinc production, so realising it depends on a viable host mine and processing stream. Confirming whether gallium is present, at what tenor, and whether it can be recovered still requires field programmes, sampling and independent assessment by qualified professionals.
