Cu CopperKalahari Copperbelt · Sediment-hosted Cu-Ag · KCB-CU-014 Illustrative model
Ngwako Pan West
Sediment-hosted copper on an untested 18 km of redox contact. Advanced target, ranked 1 of 10 nationally by model run cu-v3.2.
Prospectivity
High 0.91
Confidence
82%
Area
184 km²
Ground
Open ground
What this means for a US$2m to 20m explorer
- 01 The next step costs US$640k: 3.2 to 32 percent of a US$2m to 20m annual programme.
- 02 Open ground. Apply through the Department of Mines cadastre; approval timing is not predicted here.
- 03 Copper is +48.1% over 12 months, which supports the case.
- 04 Confidence is high enough to plan a programme. Model cu-v3.2, accepted by T. Kgosi.
Geological rationale
- +D'Kar / Ngwako Pan redox contact within 2 km34%
- +Magnetic low, interpreted graben margin22%
- +Cu-Ag-Co pathfinder anomaly (soil, 2019)19%
- +Historical occurrence density11%
- −Kalahari cover 60 to 90 m8%
Limitations
- Sparse drilling east of the anomaly
- 1978 map georeferencing ±120 m
