Summary
Data updated as at 1 Mar 2023
| ANOMALOUS METALS | Anomalous in soils: Ni, Cu, Pt Pd, Ag. Stream seds: Au, Pt, Pd. |
| MAGNETICS | Large northwest trending layered complex with weak magnetic bodies on the northeast margins and on a gravity high ridge. |
| DEPTH | 200 – 600m m to base. |
| ASSESSMENT | Large layered complex approximately 39km x 15km and trending northwest immediately west of the Yintjingga fault. Smaller magnetic features are to be targeted for magmatic Cu-Ni-PGE. Layered complex may have PGE reef potential. |
| PRIORITY | Medium priority. Historic soil lines along the axis of the Peninsula development road. |
Detail
The Koolburra area is interpreted as a large northwest trending layered complex with weak magnetic bodies on the northeast margins and is situated on a gravity high ridge. Targeting used for the soil lines was by analysing the magnetic and gravity anomalies, but, if it is a layered complex then the area could have PGE reefs and it will need more soil lines to find them to refine targeting in this large area.
- This area is interpreted as a large, layered complex approximately 39km x 15km and trending northwest immediately west of the Yintjingga fault
- It is magnetically quiet except on its eastern edge where small weakly to moderately magnetic bodies are located on a gravity high ridge
- The smaller magnetic features are to be targeted for magmatic Cu-Ni-PGE with partial leach soils. Some targets have a gravity high anomaly associated with the magnetic features
- The layered complex may have PGE reef potential.
- A Neoproterozoic age is suggested.
- Depth to basement is likely to be 350m or more.
