Six steps from opening the app to standing in the highest-probability gold zone in your area. No guesswork. No folklore. Just geology.
Open Xaureum on any device. Grant location access when prompted. The app instantly centres on your exact GPS position and identifies your region — Australia, New Zealand, or any other active coverage area.
Uses the browser Geolocation API on web and Capacitor GPS plugin on iOS and Android. Accuracy shown live in the sidebar.
Xaureum pulls real government geology data for your region from sources including Geoscience Australia, GNS Science New Zealand and USGS. This is the same data professional geologists use — simplified and overlaid on your map.
Data sourced via public WMS endpoints from Geoscience Australia (GA_Surface_Geology layer), GNS Science NZ, and USGS National Geological Map Database. Cached for 24 hours to reduce load times.
Our gold trap physics algorithm scores every 50-metre segment of every river and creek within your view. It looks for the conditions where alluvial gold naturally settles: inside bends, behind bedrock, at confluences, in flood trap zones.
Weighted scoring: geology 40%, historical mining records 25%, community finds 20%, topography 15%. Score range 0-100. Updated every 50 metres as you move.
The result is a colour-coded probability heatmap overlaid on your map. Red means high probability. Yellow means medium. Green means low. Tap any zone to see the full score breakdown explaining exactly why that score was assigned.
Rendered as a Mapbox GL layer using score-to-colour mapping. Score breakdown shows individual factor contributions. Updates in real time as you move through the field.
Walk toward the high-scoring zone. Your GPS dot moves with you and the score updates every 50 metres. The app works fully offline once you have downloaded a region — essential for remote goldfields with no mobile signal.
Offline mode available on Explorer and Pro plans. Region downloads cache geology tiles, score data and map tiles for offline access. Download before leaving home.
Found colour? Mark the exact spot as a waypoint, photograph your find, and log the weight and method. Your dig log builds over time into a personal goldfield map of every location you have worked.
Waypoints saved to Supabase with GPS coordinates and score at time of pin. Dig log supports weight, depth, method and photo upload. Pro users can contribute anonymised finds to the community heatmap.
Gold is 19 times denser than water. It behaves predictably in moving water. These are the six trap types Xaureum scores for.
Gold is heavy. As water slows around the inside of a bend, it drops its load. The inside of bends are the most consistent natural gold traps.
Gold sinks through gravel until it hits bedrock. Exposed bedrock in a streambed, especially with cracks and crevices, traps gold that has travelled downstream for thousands of years.
Where two creeks meet, water slows and mixes. The turbulence drops heavy material. Confluences are consistently productive across all gold-bearing river systems.
Major flood events can move large amounts of gold. Areas where floodwater slows and spreads — behind large boulders, in wide flat sections — accumulate gold over time.
Where a steep creek suddenly flattens, water velocity drops and gold settles. Xaureum uses topographic data to identify these gradient change points automatically.
Gold-bearing quartz reefs intersect other rock types. Where two geology types meet on a map, there is often a structural reason for gold to concentrate.
Every geology layer in Xaureum comes from a government geological survey. Free, authoritative, and updated regularly.
