Gold follows geology
NZ's gold is tied to the schist — the metamorphic grade and textural zones map where mineralising fluids moved. Read the geology and you read the ground.
Four ways prospectors put it to work
Host rocks at a glance
See the schist and units that carry gold.
Metamorphic grade
Textural zones flag the right metamorphic ground.
Structure & contacts
Faults and contacts where gold concentrates.
Tie it to the surface
Overlay geochem and occurrences to see why an anomaly sits where it does.
Seamless bedrock, nationwide
1:250k geology

Where it's been tested.
Geology questions, straight answers.
The GNS Science 1:250,000 geological map, plus metamorphic and textural-zone datasets.
In NZ, gold concentrates in particular schist textural zones — reading them narrows the search fast.
Survey-scale bedrock units, contacts and structures — enough to read the host rocks.
