Tellurium prospectivityacross Australia, the USA, Canada & worldwide.

MineDSS models two families: epithermal gold–silver systems and polymetallic systems. Epithermal systems host gold, silver, lead and mercury tellurides, such as calaverite, sylvanite, petzite and hessite, in shallow, structurally controlled veins, and the richest are commonly tied to alkaline magmatism. Polymetallic systems concentrate the same telluride mineralisation in veins that also carry base-metal sulphides of lead, zinc and copper. Although most tellurium reaches market as a by-product of copper refining, the model targets primary tellurium enrichment in these precious-metal systems, ranking 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 tellurium 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 gold, bismuth, selenium, antimony, silver, copper and molybdenum, with gold, bismuth and selenium leading. Gold reflects the intimate association between tellurium and precious metals in these systems, while bismuth, selenium and the remaining elements trace the chalcophile and sulphide chemistry that accompanies telluride deposition. 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. The model is trained on the most anomalously tellurium-rich samples (samples assaying at or above 1 ppm tellurium), not to certify a deposit. It is not a discovery, not a JORC or NI 43-101 resource or reserve estimate, and not drilling or investment advice. Confirming whether tellurium is present, and in what quantity and grade, still requires field programmes, drilling and independent assessment by qualified professionals.
