Placer deposit.

Pontijn (or Pontyn) river, near Asemasen town, SE cost of Borneo.
2 km NE of Riam Pinang
Exsolution/recrystallization two-stage process from a homogeneous Fe/Cu/Ni sulfide melt : Exsolution into MSS (monosulfide solid solution) and ISS (intermediate solid solution) and evolution of MSS into pentlandite+heazlewoodite and of ISS into chalcopyrite+bornite.
