Gold and other heavy metals settle where the current slows. We score entire stream networks for that geometry, region by region.

How the app works

The same tools in every region: read the terrain, open the catchment, check the score, mark what you find.

See the shape of the groundA dark, quiet base instead of satellite imagery: hillshade and contour lines show the valley, the ridge and the point where the slope breaks. Score colours read at full contrast here; you see which branch comes from where at a glance.
See the whole catchmentTap a segment: the boundary of the catchment feeding it is drawn, every branch inside on one screen. Where the current slows, below junctions, on inside-bend bars and where bedrock breaks the surface — all marked.
See where a score standsThis segment’s place on the colour scale, its rank, source, bed, catchment and elevation in one list. The score is not a promise of gold but a sign of trap geometry — the same card shows what earned the points.
Decide what you seeSwitch layers on and off, slide the weights. You decide what matters; the map recolours instantly.
See the no-go zones before you leaveNational parks, nature reserves and heritage sites are hatched red on the map; the streams inside them drop off the list. No wasted trip to a closed area.
Write it where you saw itDrop a marker on the selected point with one tap: icon, title, date, note, photo. The marker stays on the map; next trip, tap the icon and read your notes.
Take the list with youThe highest-scoring segments in one list; export as GPX or CSV. Download your area in advance and the map keeps working in the valley without a signal.
Mobile

Carry it in your pocket

Why Türkiye

  • Orogenic and epithermal gold belts from the Aegean to the Pontides.
  • Placer country: steep, young drainages that sort heavy minerals fast.
  • The first country the engine ran end to end — the proof behind every other page here.

Where we are

Live today. The map, scoring and field tools are in Turkish; an English interface is on the roadmap.

GOLDONGO is a terrain-screening tool. A score is not a promise of gold, and it is not a licence: check land status and follow local rules before you dig.
