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 the resource modeling process. 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 opted for the Isatis.neo clustering tool to overcome it, combining grades and the orebody thickness. They generated two domains that successfully separated the two grade populations. Without this, small areas of extreme grades would not have been considered in the estimation, and planning would not have targeted them.
