High-resolution bare-earth hillshade analysis reveals what satellite imagery cannot — ancient watercourses, bedrock structure, tailings, shafts, and the subtle topographic signatures of historic workings.
What you can see
Lidar-derived 1m and 2m resolution DEMs from the ELVIS national elevation dataset, processed into multi-azimuth hillshade overlays that reveal micro-topography invisible to the naked eye or conventional satellite imagery.
Thousands of historic shafts, pits, costeans, and alluvial workings mapped from NSW Government records back to the 1800s. See exactly where prospectors found gold before you.
Vegetation and structures removed. Pure terrain. Multi-azimuth illumination exposes drainage lines, bedrock ridges, fault traces, and ancient creek channels that held alluvial gold.
Trace palaeochannels and benches where gold concentrates over geologic time. Shadow consensus analysis across four illumination angles confirms drainage features with high confidence.
Fault traces and shear zones are gold highways. Lineament density analysis highlights the structural corridors most likely to host reef and contact-style mineralisation.
Overlay current mining leases and expired historic titles so you know exactly what ground is taken, what is open, and where the miners have been throughout history.
A composite terrain analysis scores every cell in your area across alluvial, structural, slope-break, and roughness indicators — giving you a ranked prospectivity map.
The process
Government Lidar surveys are processed into bare-earth digital elevation models at 1–2m resolution across NSW.
Each DEM is processed with four azimuth angles (NE, SE, SW, NW) to reveal terrain features regardless of illumination direction.
Drainage shadows, lineament edges, slope breaks, and terrain roughness are extracted and cross-referenced across all four azimuths.
Alluvial and structural signals are combined into a prospectivity score overlaid on the map, updated in real time as you explore.
