Not modelled
Ranked targets come with national models in Australia, the United States and Canada. 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.

The deposit system
Molybdenum is a refractory transition metal valued for the strength, hardness and heat resistance it confers on steel and specialty alloys. In nature it occurs chiefly as molybdenite, a molybdenum sulphide, and it is recovered both as the primary product of Climax-type porphyry molybdenum systems and as a by-product of porphyry copper mining.
MineDSS models molybdenum through two deposit systems: porphyry and vein molybdenum systems. Each is associated with felsic intrusions, hydrothermal alteration and structurally focused sulphide mineralisation. These processes leave a mappable footprint: altered and veined intrusive rocks, characteristic geophysical responses and a distinctive multi-element geochemical halo. That is exactly the pattern a prospectivity model is built to read across large, partly covered terrains.
Porphyry molybdenum systems form above felsic to intermediate intrusions emplaced at shallow crustal levels, where fluids exsolving from the cooling magma deposit molybdenite in dense quartz stockwork veins within and around the causative pluton. Vein systems concentrate the same mineralisation along faults, fractures and greisen zones on the margins of granitic bodies. Both are marked by potassic and phyllic alteration, silicification and zoned sulphide assemblages.
Molybdenum is a strategic industrial metal and features on critical-minerals lists in several jurisdictions. It is essential to high-strength, corrosion-resistant and high-temperature steels used in energy infrastructure, transport and defence, and demand is reinforced by the buildout of pipelines, power generation, chemical processing and clean-energy technologies. Because much production comes as a by-product of copper, its supply is partly tied to copper markets, which sharpens interest in primary molybdenum sources. Reliable identification of prospective ground supports secure, diversified supply for both enterprise and government stakeholders.
The dominant use of molybdenum is as an alloying element in steel and cast iron, where it raises strength, hardenability, toughness and resistance to corrosion and high temperature. It is central to stainless and tool steels, and to nickel- and cobalt-based superalloys for aerospace and power generation. Molybdenum compounds also serve as industrial catalysts (notably in petroleum refining and desulphurisation) and as high-performance lubricants, pigments, corrosion inhibitors and specialty chemical feedstocks.
Questions
MineDSS models two deposit systems: porphyry and vein molybdenum systems. Porphyry systems host molybdenite in quartz stockwork veins above shallow felsic intrusions, while vein systems concentrate mineralisation along faults, fractures and greisen zones on granitic margins. Molybdenum is won both as the primary metal of Climax-type porphyry molybdenum deposits and as a by-product of porphyry copper, and both routes fall within these systems. The model does not attempt to represent unrelated deposit 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 molybdenum run in Australia, the United States and Canada, with ranked targets. Molybdenum is not modelled outside those countries. Skill is model-level, never a specific site's measured accuracy, and never a discovery or JORC / NI 43-101 resource claim.
A MineDSS score ranks ground by how strongly its evidence (geology, geophysics, terrain and satellite alteration) matches the ground where samples assay anomalously high for molybdenum. It is a relative ranking for prioritising exploration: not a discovery, not a JORC or NI 43-101 resource estimate, and not drilling or investment advice. Read it together with the analogue-support class on each target: a high score on a strong match is a lead to take seriously; a high score on unproven ground is a prompt to collect field samples first.
The classic pathfinders are copper, tungsten, bismuth, tin, lead and zinc, with copper, tungsten and bismuth leading for porphyry and vein systems. These elements reflect the intrusion-related, greisen and sulphide associations typical of molybdenite mineralisation. 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.
