epithermal / vein

Silver prospectivityacross Australia, the USA, Canada & worldwide.

Epithermal and vein silver, ranked and explained across Australia, the United States and Canada, and available worldwide.

Ranked targets come with national models in Australia, the United States and Canada. 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.

The deposit system

The silver system.

Silver is a precious metal that is also a genuine industrial workhorse, and the two roles keep demand for it broad and persistent. MineDSS focuses on the epithermal and vein systems that host much of the world's primary silver: mineralisation deposited in the shallow crust from hot, circulating fluids, typically in and above volcanic arcs.

More on silver

These are the classic bonanza vein and disseminated deposits, where silver occurs as native metal, argentite and sulphosalts alongside gold and base-metal sulphides. This page covers that epithermal route specifically; the base-metal silver that travels with lead and zinc in SEDEX and VMS settings is a distinct system modelled separately.

The deposit model

Epithermal and vein silver forms at shallow crustal levels, where near-surface hydrothermal fluids deposit metal in veins, stockworks and breccias, most often in felsic to intermediate volcanic and volcaniclastic rocks above active or recently active magmatic systems. Mineralisation is strongly structurally controlled (hosted along faults, fissures and volcanic conduits) and carries a diagnostic alteration halo, from silicification and quartz-adularia through argillic clays to broader propylitic zones. Silver sits with gold, base-metal sulphides and sulphosalts.

Why it matters

Silver occupies an unusual position: a monetary and investment metal with deep, liquid markets, and at the same time an irreplaceable industrial input. That dual demand makes it structurally resilient across commodity cycles. Its industrial pull is increasingly tied to electrification and the energy transition (photovoltaics above all), while investment and monetary demand persist independently. Because much silver is produced as a by-product of gold and base-metal mining, primary epithermal silver remains a distinct and continuously pursued exploration target, keeping the search for new vein systems active across the Americas and Australia.

Where it's used

Silver has the highest electrical and thermal conductivity of any metal, which anchors its industrial use. It is essential to solar photovoltaic cells, printed and flexible electronics, contacts, switches and conductive pastes, and to brazing alloys and high-reliability soldering. Its antimicrobial properties support medical and water-treatment uses, and its optical behaviour serves mirrors, catalysis and specialised coatings, alongside enduring roles in investment bullion, jewellery and silverware.

Questions

Silver: common questions.

Which silver deposit types does MineDSS model? +

This page covers epithermal and vein silver systems: the shallow-crustal hydrothermal deposits, typically in volcanic settings, where silver occurs as native metal, argentite and sulphosalts alongside gold and base-metal sulphides. It is deliberately distinct from base-metal silver, which travels with lead and zinc in SEDEX and VMS settings and is modelled separately as the lead-zinc-silver system, so each is ranked against the geology that actually controls it.

How is the model tested, and where can I run silver? +

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 silver 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.

Which pathfinder elements track silver? +

A broad epithermal-focused geochemical suite: tellurium, thallium and mercury as the epithermal signature, together with gold, arsenic, antimony, lead, zinc, copper, molybdenum, bismuth, barium, cadmium, sulphur and selenium. 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 silver ranking mean there is a deposit or a resource? +

No. MineDSS ranks ground by how closely its evidence matches ground where samples assay anomalously high for silver. It highlights where the conditions and footprint are favourable, to help prioritise where to look next. A high ranking is not a discovery, not a JORC or NI 43-101 resource or reserve estimate, and not drilling or investment advice. Ground truth still requires fieldwork, sampling and drilling.
