- Mineral chemistry studies, including DES in-house developed Machine Learning “fingerprinting” workflows were deployed to highlight an area with strikingly similar mineral chemistry to the Jwaneng cluster of kimberlites.
- Numerous geophysical techniques have been used to create a 3D model of the area in order to identify possible diamondiferous alluvial gravels underneath the relatively shallow Kalahari sands. These included Ground Penetrating Radar (GPR), Frequency Domain Electromagnetic (EM) surveys and Resistivity/Conductivity (Res) surveys.
- While the GPR and EM surveys were inconclusive, the Res data, although acquired on a limited scale, indicated potential diamond mineralisation features.
- Six sites have been proposed for drilling to target interpreted diamondiferous gravels and ground-truth the geophysical model and to provide additional samples for analysis. Applications have been made for the required environmental permits for this drilling programme.
