Our data
The estate, measured.
Every ranking draws on the same holdings: the published geoscience of 40 countries, reconciled onto one vocabulary, audited, and kept current. These are the numbers as they stand, generated from the data itself and never written by hand.

Layer by layer
What we hold.
A jurisdiction is a publisher's reporting unit: a state, a province or a nation. A country is a country. The two columns are different numbers, and we keep them apart.
| Layer | What it holds | Features | Jurisdictions | Countries |
|---|---|---|---|---|
| Geology | Mapped geological units, with lithology and age where the publisher states them | 6,356,791 | 57 | 40 |
| Structure | Faults, folds, lineaments and oriented structural measurements | 10,581,778 | 40 | 25 |
| Deposits and occurrences | Mineral deposits and recorded occurrences | 1,338,421 | 36 | 20 |
| Tenure | Exploration and mining titles from the licensing authorities' own registers | 8,719,310 | 65 | 48 |
| Protected and excluded ground | Parks, reserves and other ground withheld from mineral entry | 2,262,827 | 41 | 27 |
| Drillhole collars | Drillhole collars | 489,790 | 4 | 4 |
| Geochemical samples | Published assays of soil, stream sediment, rock and drill samples, on one analytical roster of 118 fields. Distinct samples: the 200,586,755 published records hold the same sample more than once, mostly the same publisher's data in two releases or an earlier compilation. | 110,012,442 | · | 34 |
Structure includes lineaments interpreted from imagery as well as mapped faults, contacts and oriented measurements; every row says which it is.
The geochemical holdings are concentrated: 94.8% of records are Australian. We tell you how deep a country's record runs before you plan around it.

The geochemistry
Every element, on one roster.
1.01B laboratory determinations on 110M distinct samples, on one element roster that covers the full platinum-group suite and every rare-earth element, with yttrium and scandium.
The chart shows the share of samples with a reported value for each element. Select an element to see where we model it and what we do for it.

Below the surface
The drill-core spectral archive.
Australia's national core library has scanned drill core with a hyperspectral instrument for years, from the visible to the thermal infrared. We hold the harvest, normalised, and paired with laboratory assays wherever the two can be lined up: what mineralised rock looks like to an instrument, and what it actually contains.
Scans published by the AuScope National Virtual Core Library with CSIRO and the state and territory geological surveys; the harvest, the normalisation and the pairing are ours.
