What the model reads for gold.
Every gold target is scored on the same seven lines of evidence — with a pathfinder-geochemistry signature tuned to this system.
Host rock
rock type and age
Gravity & magnetics
buried structures and intrusions
Radiometrics
potassium, thorium, uranium
Terrain shape
elevation, slope, aspect
Surface texture

Pathfinder geochemistry the model weighs
Lead signal: Arsenic, antimony and bismuth. These are the elements this national model actually reads to rank gold ground.

What is gold?
Gold is the archetypal exploration target — high value, globally liquid, and hosted across a wide range of geological settings. MineDSS focuses on the two systems that hold most of the world's hard-rock gold: orogenic (mesothermal) lode gold, deposited where mineralising fluids move along major crustal faults during mountain-building, and intrusion-related gold, sourced from cooling granitic bodies at depth. Both leave a chemical and geophysical footprint far larger than the ore itself — and that footprint is what a prospectivity model learns to read.
The deposit model
Orogenic gold clusters along deep, long-lived fault systems and their splays, typically in deformed greenstone belts and metasedimentary terranes. It is strongly structurally controlled, commonly accompanied by quartz-carbonate veining and sericite-carbonate alteration, with the gold associated with sulphides such as arsenopyrite and pyrite. Intrusion-related systems sit in and around felsic intrusions as sheeted vein arrays with a characteristic metal association. MineDSS reads these settings through mapped geology and rock age, gravity and magnetic structure, radiometrics, terrain, satellite alteration and the pathfinder geochemistry below.
Why it matters
Gold underpins a large share of global exploration spend and the majority of listed explorers on the ASX and TSX. As a monetary metal held by central banks and investors as a store of value, its demand stays structurally resilient through commodity cycles — which keeps the search for new ounces continuous.
Where it's used
Beyond investment and jewellery, gold's resistance to corrosion and excellent conductivity make it essential in high-reliability electronics — connectors, bonding wire and circuitry — as well as dentistry, medical devices and aerospace components.
How MineDSS reads it
In MineDSS national validation, the single strongest signal for gold is arsenic — the classic gold pathfinder — followed by silver and the host-rock setting, then gravity and magnetic structure. The model weighs a full pathfinder suite alongside geophysics and satellite alteration, so a target reflects the whole mineralising system, not a single anomalous sample.
Gold prospectivity — common questions
What gold deposit types does MineDSS model?
Orogenic (mesothermal) lode gold and intrusion-related gold systems — the settings that host most of the world's hard-rock gold. The same engine has strong analogue support in classic gold districts, including the Carlin Trend in Nevada and Val-d'Or in Quebec.
How is the gold model's accuracy measured?
We validate every model the hard way — held-out spatial cross-validation. We hide known deposits, rebuild the model without them, then test whether it still finds them, with test blocks kept spatially separated so it cannot memorise nearby points. We are currently refreshing our published national skill figures so they reflect deployment-time performance, and will republish them per model. Coverage today spans Australia, the United States and Canada; the figures are model-level skill, never a specific site's measured accuracy, and never a discovery or JORC / NI 43-101 resource claim.
What data drives a gold target?
Pathfinder geochemistry (arsenic, antimony, bismuth, silver and associated metals), mapped geology and rock age, gravity and magnetics, radiometrics, terrain, and satellite-derived alteration — combined into a single ranked, explainable score.
Can I tune the model to my ground?
Yes. Upload your own assays or drillholes and a custom model sharpens to your project — used only for your job, never added to anyone else's model.
