What the model reads for lead, zinc & silver.
Every lead, zinc & silver target is scored against the full national evidence stack — mapped geology and rock age, gravity and magnetics, radiometrics, terrain, satellite radar and alteration — the way a geologist reads a map sheet, with a pathfinder-geochemistry signature tuned to this system.
Pathfinder geochemistry the model weighs
Lead signal: The base-metal sulphide suite — cadmium, barium and sulphur. These are the elements this national model actually reads to rank lead, zinc & silver ground.

What is lead, zinc & silver?
Lead, zinc and silver are the classic base-metal trio, most often mined together from the same sulphide bodies. MineDSS focuses on the two systems that supply the bulk of the world's zinc and a major share of its lead and silver: sediment-hosted (SEDEX) deposits, formed where metal-bearing brines vent into a sedimentary basin and precipitate stratabound lead-zinc-silver sulphides, and volcanogenic massive sulphide (VMS) systems, deposited on and beneath the seafloor from hydrothermal fluids circulating through submarine volcanic piles. Both are large, chemically distinctive sulphide accumulations, and the silver they carry is by-product silver bound in that base-metal ore — distinct from the epithermal silver MineDSS models separately.
The deposit model
SEDEX systems are stratabound, hosted in fine-grained clastic and carbonaceous basin sediments, and controlled by growth faults and sub-basins that channel hot, metalliferous brines onto the seafloor, where sphalerite, galena and iron sulphides precipitate as bedded ore, commonly with a barite or exhalative signature. VMS bodies sit within submarine volcanic and volcano-sedimentary sequences as lens-shaped massive sulphides above a discordant feeder stockwork, with chlorite-sericite alteration marking the fluid pathway. Both are strongly stratigraphically and structurally controlled. MineDSS reads these settings through mapped geology and rock age, gravity and magnetic structure, radiometrics, terrain, satellite alteration mapping, and the pathfinder geochemistry below — resolving the broad hydrothermal footprint rather than the ore lens alone.
Why it matters
Zinc, lead and silver sit at the centre of industrial and energy-transition demand. Zinc is the primary defence against steel corrosion through galvanising, making it fundamental to construction, infrastructure and vehicles. Lead remains essential to stationary and backup energy storage, and silver is central to electrification, grid buildout and solar manufacturing. Because base-metal supply is concentrated in a relatively small number of large sulphide deposits, and grades decline as mature mines deplete, the search for new SEDEX and VMS ground stays commercially significant across the cycle.
Where it's used
Zinc protects steel through galvanising and alloys into brass and die-cast components. Lead dominates lead-acid batteries for vehicles, standby and backup power (UPS, telecoms), and is used in radiation shielding and specialist alloys. Silver combines the highest electrical and thermal conductivity of any metal with strong optical reflectivity, making it essential to solar photovoltaics, electronics, contacts and brazing alloys, alongside its longstanding roles in jewellery, coinage and investment.
How MineDSS reads it
Because SEDEX and VMS ore is a sulphide system, MineDSS reads a base-metal sulphide pathfinder suite — silver, copper, gold, arsenic, antimony, bismuth, molybdenum, cadmium, barium, sulphur, tellurium, selenium, mercury, thallium and indium — alongside geophysical structure and satellite alteration. The base-metal sulphide indicators of cadmium, barium and sulphur are particularly informative for these systems. Weighing the whole suite together means a ranked target reflects the entire mineralising system, not a single anomalous sample.
Lead, zinc & silver prospectivity — common questions
Which lead-zinc-silver deposit types does MineDSS model?
Two: sediment-hosted (SEDEX) systems, where metal-rich basin brines precipitate stratabound lead-zinc-silver sulphides, and volcanogenic massive sulphide (VMS) systems, formed from hydrothermal fluids in submarine volcanic sequences. Together these supply most of the world's mined zinc and a major share of its lead and silver. The by-product silver in this base-metal route is distinct from the epithermal silver MineDSS models separately. Mount Isa in Queensland is a well-known example of this style of endowment.
How is the model validated, and where is lead, zinc & silver available?
Every MineDSS model is tested the hard way before it is served: we hide known deposits, rebuild the model without them, then test whether it still finds them, with test ground kept spatially separated so the model cannot memorise nearby points. A model that does not pass our release gates is not offered — for any mineral, in any country. Coverage today for lead, zinc & silver spans Australia, the United States and Canada. Skill is model-level, never a specific site's measured accuracy, and never a discovery or JORC / NI 43-101 resource claim.
Why model lead, zinc and silver together?
Because they occur together. In SEDEX and VMS deposits the same sulphide bodies carry sphalerite, galena and by-product silver, so they share host rocks, structural controls, alteration and a common geochemical footprint. Modelling them as one base-metal system reflects how the ore actually forms and is mined, rather than treating co-located metals as unrelated targets.
Does a high ranking mean there is a deposit or a resource in the ground?
No. MineDSS ranks ground by how closely its geology, geophysics, satellite alteration and pathfinder geochemistry resemble known SEDEX and VMS systems. A high rank flags prospectivity for follow-up work, not a confirmed discovery, and it is never a JORC or NI 43-101 resource or reserve estimate, nor investment or drilling advice. Ranked ground still requires field validation and drilling to test.
