Why this target scores 0.91
Feature influence from the physics-informed model. Constraints listed in the run record.
- + D'Kar / Ngwako Pan redox contact within 2 km 34%
- + Magnetic low, interpreted graben margin 22%
- + Cu-Ag-Co pathfinder anomaly (soil, 2019) 19%
- + Historical occurrence density 11%
- − Kalahari cover 60 to 90 m 8%
Limitations
- Sparse drilling east of the anomaly
- 1978 map georeferencing ±120 m
