The Isatis.neo sample clustering tool identifies finely two complex geological domains in a platinum group metal deposit.
Geological domaining is a crucial step in resource modeling. However, domains can be challenging to identify when grade populations are too intricate. Sibanye-Stillwater faced one such challenge for a PGM (platinum group metals) deposit with complex low-grade and very high-grade zones and several faults. They used the Isatis.neo clustering tool to address it, combining grades and orebody thickness. They generated two domains that successfully separated the two grade populations. Without this, the estimation would not have considered small areas of extreme grades, and planning would not have targeted them.
