What it is

Read the ground's fingerprint

British Columbia's Regional Geochemical Survey is one of the richest public datasets anywhere. Detector Maps plots stream-sediment, soil, till and rock-chip gold assays where each sample sits — filter for gold and read the highs and clusters that point at mineralised ground.

What the layer shows you

Four ways prospectors put it to work

01

Stream, soil, till & rock

Every sample medium, plotted at the collection site.

02

Anomalies, not just dots

Read the clusters and highs that flag mineralised ground.

03

Till tells the story

Glacial till geochem traces gold back up-ice to source.

04

Confirm a target

Ground-truth a geochem high before you drive.

FAQ

Geochemistry questions, straight answers.

Gold assays from regional stream-sediment, soil, till and rock-chip sampling, plotted where each sample was taken.

BC’s Regional Geochemical Survey (RGS) and related public geochemical datasets.

Much of BC is glaciated — gold in till is carried down-ice from source, so a till anomaly points you back up-ice to the bedrock target.

Strong, clustered highs point at mineralised ground — pair them with geology and occurrences before you commit.
